5F6EA32AC5C4522EAA1B6E0CB577A06D.taxon	description	Description. The present material is poorly preserved and only fragmentary. The illustrated specimen is 23 mm high. The whorl face is weakly concave. The whorls are ornamented with a subsutural row of knobs and two strong, knobby spiral cords below it, followed by one or two weak spiral cords and a strong, knobby suprasutural spiral cord. The knobby sub- and suprasutural cords form a bulge on which the suture is situated. The base is flat and its transition to the whorl face is angulated. A distinct umbilicus is present. The aperture is rhomboid. It is unclear whether a siphonal canal is present. The aperture has a parietal, a columellar, and a palatal plait.	en	Gruendel, Joachim, Keupp, Helmut, Lang, Fritz, Nuetzel, Alexander (2022): Late Jurassic (Upper Kimmeridgian) Heterobranchia (Gastropoda) of the coral-facies of Saal near Kelheim and the viciniy of Nattheim (Germany).

Larger specimens have a somewhat inflated last whorl. The sutures are distinct. The whorls have a relatively broad, strongly oblique ramp, demarcated from whorl face by an edge. The spire whorls are broad and low. The early whorls have opisthocline axial ribs which weaken during ontogeny and finally change to strengthened growth lines. The ribs or strengthened growth lines run prosocyrt opisthocline from edge near ramp to base, and curve strongly backward at the edge that demarcates the ramp. The course of the growth lines is not visible on the ramp. Spiral ornament is absent. The base is strongly convex and smooth except of growth lines. The aperture is narrow and acute adapically. It has a short, oblique siphonal canal.	en	Gruendel, Joachim, Keupp, Helmut, Lang, Fritz, Nuetzel, Alexander (2022): Late Jurassic (Upper Kimmeridgian) Heterobranchia (Gastropoda) of the coral-facies of Saal near Kelheim and the viciniy of Nattheim (Germany).

ADB72959ADC75A068D92D7EA86C96C16.taxon	description	Description. A large specimen is 3.2 mm high. The shell is fusiform, relatively slender with a high spire. The whorls are rather high and have a distinct, oblique ramp, demarcated from whorl face by a spiral cord. The whorl face is straight. The suture is distinct and is accentuated by the ramp. The whorls are ornamented with straight, slightly opisthocline, rounded axial ribs separated by wide interspaces. The ribs become weaker and may fade entirely on the last preserved whorl. The transition from whorl face to base is evenly rounded. The ribs do not continue onto the smooth base. The aperture is oval, higher than wide, with a weak, short canal and an acute posterior part. The inner lip is reflexed in the columellar portion.	en	Gruendel, Joachim, Keupp, Helmut, Lang, Fritz, Nuetzel, Alexander (2022): Late Jurassic (Upper Kimmeridgian) Heterobranchia (Gastropoda) of the coral-facies of Saal near Kelheim and the viciniy of Nattheim (Germany).

F1B9336CCEA053A4B954E428979AC80D.taxon	description	Description. The holotype is 15 mm high. The early teleoconch is conical, acute, coeloconoid, slender, and consists of numerous very low whorls. A relatively well-preserved juvenile paratype (Plate 8: fig. 4) has a flat ramp demarcated by a distinct angulation. Later whorls increase more rapidly in width producing coeloconoid shape. The last part of the last whorl is deflected downward so that the height of the whorl increases more rapidly. The transition from whorl face to the strongly convex base is evenly rounded. The last whorl is strongly convex and somewhat inflated. The shell is smooth, except in rare cases (due to preservation?) with a narrow subsutural spiral furrow. The base is narrowly phaneromphalous. The aperture is strongly damaged in all specimens; it has a strong parietal plait and two columellar plaits (adapical one weaker).	en	Gruendel, Joachim, Keupp, Helmut, Lang, Fritz, Nuetzel, Alexander (2022): Late Jurassic (Upper Kimmeridgian) Heterobranchia (Gastropoda) of the coral-facies of Saal near Kelheim and the viciniy of Nattheim (Germany).

0C349C98DA6B5AE5AD19196F19CF9AFC.taxon	description	Description. The largest fragment is 58 mm high. The shell is slender. The whorls increase regularly in width. The sutures are situated in the middle of a bulge that is formed by two neighbouring whorls. The whorl face is distinctly concave. The whorl face is ornamented with broad, orthocline axial ribs that reach from suture to suture in early whorls but may be reduced on late whorls except of nodes. They are thickened and node-like near the sutures. The whorls are deepened and pit-like between the axial ribs at mid-whorl. Juvenile specimens have two spiral cords between the nodes. The base is flat, smooth, and distinctly umbilicated. The transition from base to whorl face is sharply angulated. Sections show that the aperture is rhomboid and has two columellar plaits, a parietal, a palatal, and a basal plait.	en	Gruendel, Joachim, Keupp, Helmut, Lang, Fritz, Nuetzel, Alexander (2022): Late Jurassic (Upper Kimmeridgian) Heterobranchia (Gastropoda) of the coral-facies of Saal near Kelheim and the viciniy of Nattheim (Germany).

The whorls are regularly increasing in width forming an acutely conical shell. The whorls are relatively low with concave whorl face. The earliest whorls are poorly preserved. Later whorls seem to have a subsutural, weakly knobby bulge. The suture is barely visible. One or two weak knobby spiral cords below the bulge are present. The knobs of the bordering spiral cord emerge from the abapical suture. The whorl face is ornamented with broad, barely visible axial ribs. The base is flat and its transition to the whorl face is almost rectangular with a distinctly knobby bodering spiral cord. The base is entirely covered with numerous densely spaced, fine spiral cords. The aperture is not preserved; it probably has at least a columellar and a parietal plait.	en	Gruendel, Joachim, Keupp, Helmut, Lang, Fritz, Nuetzel, Alexander (2022): Late Jurassic (Upper Kimmeridgian) Heterobranchia (Gastropoda) of the coral-facies of Saal near Kelheim and the viciniy of Nattheim (Germany).

019703F140FF5EF78046D4D202DE0915.taxon	description	Description. A large specimen is 30 mm high. The shell is very slender. The whorls are slowly increasing in width. The apical angle is somewhat variable. The whorl face is concave and ornamented with a subsutural bulge (smooth or knobby), with a strong and distinctly knobby spiral cord at approximately mid-whorl, and a narrow projecting bordering spiral cord that emerges above the suture. This cord demarcates the flat base from whorl face. Only very well preserved specimens show further weak spiral cords between adapical bulge and median spiral cord, and another between median spiral cord and abapical suture. They are at least partly knobby. The base lacks ornament. The rhomboid aperture has a siphonal canal.

641661AB2F5E5785B30A5A9FE453731C.taxon	description	Description. A specimen is 120 mm high. The shell is very slender, needle-shaped. The shell has a pronounced bulge at the suture that is formed by two neighbouring whorls. The suture lies on this bulge. The whorl face is distinctly concave between the bulges where it is entirely covered with numerous weak spiral cords. Details of this ornament cannot be recognized because of insufficient preservation. The base is flat with an angular transition to the whorl face. The aperture is damaged in all specimens; it probably has a rhomboid outline and a distinct siphonal canal, a columellar plait that forms the adapical border of the canal, and a parietal plait.	en	Gruendel, Joachim, Keupp, Helmut, Lang, Fritz, Nuetzel, Alexander (2022): Late Jurassic (Upper Kimmeridgian) Heterobranchia (Gastropoda) of the coral-facies of Saal near Kelheim and the viciniy of Nattheim (Germany).

03C8F07BEC87525E868F3FA2C68BE3BE.taxon	diagnosis	Diagnosis. The adapical part of the shell is slender with many whorls lacking a ramp. Later whorls are broad in relation to their height and have a ramp which becomes broader from whorl to whorl in most specimens. Below the ramp, a weak concavity (lateral view) is developed; rarely, the ramp remains narrow and the concavity is lacking. The last whorls of large specimens increase only slowly in width and this part of the shell is more or less cylindrical. The transition from whorl face to base is evenly rounded without edge or spiral cord. Aperture with two columellar and palatal plaits and one parietal plait. This species is present in two morphotypes and specimens that are intermediate: Morphotype 1: Plate 18: figs 1 - 10; Transition from morphotype 1 to morphotype 2: Plate 18: fig. 11; Morphotype 2: Plate 18: figs 12 - 14.	en	Gruendel, Joachim, Keupp, Helmut, Lang, Fritz, Nuetzel, Alexander (2022): Late Jurassic (Upper Kimmeridgian) Heterobranchia (Gastropoda) of the coral-facies of Saal near Kelheim and the viciniy of Nattheim (Germany).

03C8F07BEC87525E868F3FA2C68BE3BE.taxon	description	Description. A large specimen (early whorl missing) is 33 mm high. The early shell is very slender consisting of at least eight smooth whorls having a weakly convex whorl face and somewhat impressed sutures. The following 2 - 3 whorls increase rapidly in width and are very wide in relation to their height. As a result, the spire is coeloconoid. In the mentioned 2 - 3 whorls following the slender spire whorls, a broad, distinctly concave, funnel-shaped ramp is formed. From now on, the ontogenetic evolution of the shell follows different pathways leading to two varieties (morphotype 1 and 2 as well as to intermediate forms). In morphotype 1 (much more abundant than morphotype 2), the wide ramp continues and becomes wider. It is delimited from whorl face by a broad concavity with indistinct borders. Initially, the whorls continue to rapidly increase in width. In large, more or less fully grown specimens, the increase in width decelerates, the last whorls are high and almost cylindrical in shape. The edge of the ramp is projecting abaxially and forms the whorl periphery. In the other extreme form, morphotype 2, the rapid increase of the width of the whorls and the formation of a broad ramp is confined to 2 - 3 whorls. Afterwards, the whorls become wider and increase in width only slowly, but considerably increase in height. The ramp forms only a narrow band. The whorl face is straight and lacks a concavity below the ramp so that this part of the shell is almost cylindrical. As mentioned, there are transitional forms between varieties 1 and 2 (Plate 18: fig. 11). All individuals have a continuous, rounded transition from whorl face to the strongly convex base. Base and whorl face are smooth. The base has a distinct umbilicus. The growth lines run straight and somewhat opisthocline on the whorl face and curve strongly backward below the ramp. The aperture is very narrow, adapically acute and has a weakly developed siphonal canal. The inner lip is broadened and detached in the columellar area; it partly covers the umbilicus. The inner lip bears a strong parietal and two columellar plaits. The adapical columellar plait is weaker than the abapical one. The aperture has two palatal plaits which are, however, rarely recognizable.	en	Gruendel, Joachim, Keupp, Helmut, Lang, Fritz, Nuetzel, Alexander (2022): Late Jurassic (Upper Kimmeridgian) Heterobranchia (Gastropoda) of the coral-facies of Saal near Kelheim and the viciniy of Nattheim (Germany).

The whorls are ornamented with a subsutural row of axially elongated, opisthocline knobs. Below it, the whorl face is ornamented with three spiral cords: a weak upper one, then a stronger one and again a weak spiral cord. All spiral cords are knobby. The size of the knobs corresponds to the strength of the spiral cords. The knobs of the bordering spiral cord emerge from the abapical suture. The bordering spiral cord is strong and marks the angular transition from whorl face to the weakly convex base. The base is ornamented with at least one distinct spiral cord and possibly with additional weaker ones. The growth lines are weakly prosocyrt on the base and almost straight orthocline on the whorl face. They curve strongly backward immediately below the adapical suture.

27E915B60EF35D8AAB4BC52D99BF58CB.taxon	description	Description. The specimen is 45 mm high and has a moderately broad shape. The whorls increase regularly in width. They are distinctly wider than high. The sutures are hardly visible. The whorls are ornamented with three spiral cords. The subsutural spiral cord is the most prominent one. All spiral cords bear small knobs. The largest knobs are on the subsutural spiral cord. In the last whorls, the knobs on the middle and suprasutural spiral cord become weaker. The base is flat and has an angular transition to the whorl face which is demarcated by a spiral cord that is probably not knobby. The growth lines on the base are prosocyrt. The aperture is not preserved. Only a strong palatal plait can be recognized.	en	Gruendel, Joachim, Keupp, Helmut, Lang, Fritz, Nuetzel, Alexander (2022): Late Jurassic (Upper Kimmeridgian) Heterobranchia (Gastropoda) of the coral-facies of Saal near Kelheim and the viciniy of Nattheim (Germany).

The shell is very slender and consists of many whorls. The whorls are high with concave whorl face. The most conspicuous sculptural feature is a bulge lacking knobs (or weakly knobby?) forming the periphery which is formed by two neighbouring whorls. The suture is not clearly visible on this bulge. A weak spiral cord is present directly below the bulge followed by two stronger spiral cords in abapical direction. All spiral cords are knobby. Base and aperture are incompletely preserved. At least one columellar and a parietal plait are present. The aperture seemingly has an abapical canal.	en	Gruendel, Joachim, Keupp, Helmut, Lang, Fritz, Nuetzel, Alexander (2022): Late Jurassic (Upper Kimmeridgian) Heterobranchia (Gastropoda) of the coral-facies of Saal near Kelheim and the viciniy of Nattheim (Germany).

They have a broad, nearly horizontal ramp that is demarcated from whorl face by a sharp edge forming the periphery. The whorl face is straight, somewhat tapering abapically. The details of the ornament are commonly obscured by poor preservation. The whorls are ornamented by a spiral cord at about mid-whorl. The originals of Quenstedt (1881 - 1884) show further spiral cords. The transition from whorl face to base is demarcated by a rounded bulge that is covered by the following whorl of the spire whorls. The base is moderately convex. The aperture is elongated, rhomboid with a long, almost vertical canal. The aperture has a strong parietal plait, one somewhat weaker columellar plait, and one palatal plait.	en	Gruendel, Joachim, Keupp, Helmut, Lang, Fritz, Nuetzel, Alexander (2022): Late Jurassic (Upper Kimmeridgian) Heterobranchia (Gastropoda) of the coral-facies of Saal near Kelheim and the viciniy of Nattheim (Germany).

F381A523E38C59229B3C1A56A65D2D45.taxon	description	Description. The holotype is 22 mm high. The shell is slender, high-spired, and consists of many whorls. The whorl face is straight. The sutures are accentuated by a narrow ramp. The early whorls are poorly preserved, seemingly with two spiral cords near sutures and having a concave whorl face between the cords. Later whorls have a subsutural bulging spiral cord (weakly nodular?) that is demarcated by an abapical spiral furrow. This furrow is rarely distinct or frequently not visible at all probably due to preservation. No other ornament is present. The transition from whorl face to the strongly convex base is evenly rounded. The base has several, weakly defined, bulging spiral cords. It is anomphalous. The growth lines are indistinct; they are strongly curving backward adapically. The aperture is narrow with a weakly convex outer lip; parietal and columellar lip meet at an angle. The aperture has a distinct siphonal canal, a distinct parietal and two columellar plaits. The columellar plaits are commonly weak or not visible even in seemingly well-preserved specimens (variability or due to preservation).	en	Gruendel, Joachim, Keupp, Helmut, Lang, Fritz, Nuetzel, Alexander (2022): Late Jurassic (Upper Kimmeridgian) Heterobranchia (Gastropoda) of the coral-facies of Saal near Kelheim and the viciniy of Nattheim (Germany).

The last whorl covers all previous ones in lateral view. Some of the earlier whorls can be seen in apical view. The adapical portion of the last whorl is bulging and possibly knobby (uncertain due to poor preservation). This portion of the shell is narrower than the portion below it and is demarcated by a shallow furrow. No ornament is visible. The damaged aperture stretches from the adapical furrow to the base. It is very narrow and somewhat broadened at its abapical termination.

A4826EFB1DA4529285523B16C04C865D.taxon	description	Description. The present material consists of fragments of larger specimens and juvenile specimens. The largest specimen is 32 mm high. The apical whorls are not preserved. The shell is slender with a somewhat variable apical angle. The ornament consists of a nodular adapical bulge forming a narrow ramp. The suture is situated on the adapical portion of the bulge. The nodular spiral cord (in some specimens only very weakly developed) is mostly close to the abapical suture or - more rarely - about half way between adapical bulge and abapical suture. The number of nodes per whorl is strongly variable (only in part due to preservation). In few specimens, an additional weakly nodular spiral cord is present between the nodular spiral cord and the adapical bulge. The base is weakly convex with a pronounced spiral cord at the almost rectangular transition to the whorl face. This bordering spiral cord is sometimes nodular. The base is covered with spiral cords. The aperture has a rhomboid outline and a distinctly oblique siphonal canal. The plait pattern is only visible in few specimens. It consists of one or two columellar plaits, one strong parietal plait, while a palatal is plait very rarely visible - perhaps due to the preservation.	en	Gruendel, Joachim, Keupp, Helmut, Lang, Fritz, Nuetzel, Alexander (2022): Late Jurassic (Upper Kimmeridgian) Heterobranchia (Gastropoda) of the coral-facies of Saal near Kelheim and the viciniy of Nattheim (Germany).

2D4F9FE0F36C51ECAB7429747813F941.taxon	description	Description. The shell is very slender; a fragmentary specimen (incomplete ad- and abapically) is 62 mm high; the shell illustrated in Plate 10: fig. 6 is ca. 50 mm high. If the assignment of the specimen illustrated in Plate 10: fig. 1 is correct, then the juvenile shell is very long, slender, and consists of numerous whorls. The whorls are generally wider than high but the height / width ratio varies. The whorls increase only slowly in width. The whorl face is concave. The only recognizable ornament is a subsutural bulge forming the whorl periphery. The subsutural bulge forms a sharp crest and ramp in well-preserved specimens. The whorls have a subsutural bulge bordered by the adapical suture. The base is flat, smooth and joins the whorl face at an angular edge. The base has a narrow umbilicus. The growth lines are generally opisthocline and curve backward strongly immediately below the adapical suture. The damaged aperture has a rhomboid outline and an oblique siphonal canal, two columellar plaits, one parietal, and one palatal plait.	en	Gruendel, Joachim, Keupp, Helmut, Lang, Fritz, Nuetzel, Alexander (2022): Late Jurassic (Upper Kimmeridgian) Heterobranchia (Gastropoda) of the coral-facies of Saal near Kelheim and the viciniy of Nattheim (Germany).

36055E12A8B95738BB927475F5DAE368.taxon	description	Description. The largest specimen from Saal is 9 mm high. The shell is slender to very slender. The whorls are regularly increasing in width. The whorl face is concave, with a strong, sometimes ramp-like bulge. The bulge is formed at the suture by both whorls. The suture is situated somewhat above the middle of the bulge. The whorl face between the bulges is initially ornamented with one spiral cord, later whorls with 4 - 5 spiral cords: two of these spiral cords may be stronger than the others. The bulges and stronger spiral cords are possibly nodular (unclear due to preservation). The base is flat, with an almost rectangular transition to the whorl face. The transition has a strong, protruding bulge that is largely covered by the following whorls of the spire. The base is densely covered with weak spiral cords. The aperture has an approximately rectangular outline and distinct oblique siphonal canal. The aperture has a single parietal plait, two columellar plaits, and a palatal plait.	en	Gruendel, Joachim, Keupp, Helmut, Lang, Fritz, Nuetzel, Alexander (2022): Late Jurassic (Upper Kimmeridgian) Heterobranchia (Gastropoda) of the coral-facies of Saal near Kelheim and the viciniy of Nattheim (Germany).

9643073B122C5458B59A5ADED8998067.taxon	description	Description. A large specimen with damaged spire is 10 mm high. The shell is elongated fusiform. The last whorl is very high, cylindrical, tapering in abapical direction, embracing high on the previous whorl and covering most of it. The spire is relatively high for the genus and is acutely conical, consisting of several low whorls. A narrow but distinct horizontal ramp is formed early in ontogeny. The ramp is sharply demarcated from the whorl face by an edge. The shell is smooth. Growth lines are not visible, only on the ramp, remains of strengthened opisthocyrt growth lines are visible. The aperture is elongated, narrow and stretches over the entire height of the last whorl. Its adapical portion is narrow and acutely tapering. The abapical portion of the aperture is widened drop-shaped. The columellar portion of the aperture is covered by callus which also covers parts of the base. The abapical delimitation of the callus is formed by a somewhat oblique plait which also demarcates the columellar area from the abapical edge of the aperture. A further weak plait forms the outer edge of the callus of the aperture.	en	Gruendel, Joachim, Keupp, Helmut, Lang, Fritz, Nuetzel, Alexander (2022): Late Jurassic (Upper Kimmeridgian) Heterobranchia (Gastropoda) of the coral-facies of Saal near Kelheim and the viciniy of Nattheim (Germany).

852005829AA15D60AD7D3066727CF122.taxon	description	Description. The larger specimen is 6 mm high. The overall shape closely resembles that of Rugalindrites cylindracea. The spire is distinctly elevated and gradate. The spire whorls increase more rapidly in height than in width due to a downward shift of the suture. The whorls have a narrow ramp with a more rounded transition to the whorl face. The growth lines are almost straight and weakly prosocline. In the upper part of the whorls, they are strengthened and thread-like. The growth lines are distinctly prosocyrt on the convex base. At about mid-whorl of the last whorl, there is a broad band with a micro-ornament of numerous spiral threads (Plate 20: fig. 12). The aperture is not preserved.	en	Gruendel, Joachim, Keupp, Helmut, Lang, Fritz, Nuetzel, Alexander (2022): Late Jurassic (Upper Kimmeridgian) Heterobranchia (Gastropoda) of the coral-facies of Saal near Kelheim and the viciniy of Nattheim (Germany).

28750504D3D15FA6B148551CF2DCA777.taxon	description	Description. The shell is 4.2 mm high. It is slender oval. The last whorl is higher than the distinctly elevated and gradate spire. The whorl height increases rapidly by a downward shift of the suture. The sutures are accentuated by the presence of a narrow ramp. The whorl face is weakly convex. The spire whorls have a suprasutural spiral furrow. The transition from whorl face to the strongly convex base is evenly rounded. The base is entirely covered by spiral furrows (ca. 15). The furrows are widely distant to each other on the adapical portion of the base and become increasingly more narrowly spaced towards the abapical portion of the base. The aperture is elongated oval and acute posteriorly. The outer lip is convex. The inner lip consists of the parietal and columellar lips that meet at an obtuse angle. The columella terminates abruptly at the anterior margin of the aperture.	en	Gruendel, Joachim, Keupp, Helmut, Lang, Fritz, Nuetzel, Alexander (2022): Late Jurassic (Upper Kimmeridgian) Heterobranchia (Gastropoda) of the coral-facies of Saal near Kelheim and the viciniy of Nattheim (Germany).
