As detailed in Forel &amp; Grădinaru (2020), the revision of their classification requires the addition of new characters to avoid producing another classification system that would only be a new point of view further complicating the current situation. The peak of diversity of ornate Bairdiidae occurred in the Late Triassic but they were already present in the Permian (see Forel &amp; Crasquin 2020 and references therein for a review) as illustrated for instance by the material described herein from the Middle Permian of the Guadalupe Mountains. Specifically, the confusion and instability of the conceptions of Petasobairdia Chen, 1982 and Praelobobairdia Kozur, 1991 have recently been described and discussed in Forel &amp; Grădinaru (2020). Herein, we follow the view that Praelobobairdia is a junior synonym of Petasobairdia, as was first introduced by Becker (2001).</p> </div>	https://treatment.plazi.org/id/21095E52CF60C307FDCD511E631CEBB9	Public Domain	No known copyright restrictions apply.

In the present analysis, Bairdia sp.

Sohn (1954) observed that specimens of Ceratobairdia dorsospinosa Sohn, 1954 have one or two spines along the dorsal margin of LV. However, all other characters of the carapaces and valves are very similar, so he suggested that all specimens are conspecific. Although very similar morphologically, Ceratobairdia mescaleroella sp. nov. cannot be considered as another degree in the variability of Ceratobairdia dorsospinosa Sohn, 1954 as the lateral morphologies of the two species are significantly different as detailed above. Contrary to what was shown for Ceratobairdia dorsospinosa Sohn, 1954, Ceratobairdia mescaleroella sp. nov. has a conservative number and position of dorsal spines, the only difference observed is in the expression of the central spine.</p> </div>	https://treatment.plazi.org/id/21095E52CF5BC33EFDB8531860D5E9E7	Public Domain	No known copyright restrictions apply.

Noteworthy, Sohn (1954) considered that Bairdia monstrabilis Cooper, 1946 does not belong to Ceratobairdia mainly because of the lack of a dorsal structure at LV. Lobobairdia ventriconcava (Chen, 1958) in Chen &amp; Bao, 1986 from the Early Permian of South China (Chen &amp; Bao 1986) is similar to Ceratobairdia sexagintaduella sp. nov., but has an even shorter latero-ventral ridge and lacks the dorsal blade at LV. The morphology of the latero-ventral ridge in Ceratobairdia sexagintaduella sp. nov. is similar to that of Ceratobairdia sinensis Wang, 1978 from the Changhsingian, Late Permian of South China (Wang 1978) by the morphology of the lateroventral ridge but differs by lamellar DB at LV, PB less upturned and AB located lower. Ceratobairdia sexagintaduella sp. nov. is very similar to Bairdia permiana Hamilton, 1942 from the Kungurian of the Glass Mountains (Hamilton 1942): this species has later been shown to be a junior synonym of Bairdia pecosensis Delo, 1930 by Sohn (1960), who additionally mentioned that the ridge on the ventral part of the RV is not as pronounced as shown in the original drawing of Hamilton (1942).</p> </div>	https://treatment.plazi.org/id/21095E52CF59C338FDAB54FB65D1EE22	Public Domain	No known copyright restrictions apply.

The identification of RV is more complex and has been possible because of the description provided by Hamilton (1942: 716) of “the centrodorsal portion of the right valve flattens abruptly to hingeline, expressed as a flat terrace in dorsal bi and as a rather prominent ridge in lateral view; […]; the ventral portion of the right valve sharply infolded, forming a sharp downward projecting ridge terminating in mature molds as a backward projecting spine.”</p> <p>Hamilton (1942: 716) described the dorsal margin of LV of Ceratobairdia wordensis as “usually ornamented by two to seven short strong spines equally spaced and concentrated dorsally on the middle third or more.” The present material provided LV with 4 to 6 spines, but all other characters leave no doubt on the conspecificity of the specimens. Is the number of spines related to ontogeny? Although Hamilton (1942) mentioned 2 to 7 dorsal spines on LV, the unique specimen illustrated displays 6 spines and no discussion is provided on the possible link between size and number of the spines. Conversely, Sohn (1960: pl. 4 figs 12, 14, 17) illustrated specimens with 8 to 10 dorsal spines and at least one of them shows spines organized into 2 overlapping rows. For the present material, the number of spines along the dorsal margin of LV of Ceratobairdia wordensis ranges from 4 to 6 without pattern related to ontogeny (Fig. 10):</p> <p>• most of the smallest specimens, assigned to A-2?, are weathered but the two sufficiently well preserved at dorsal margin show 5 spines, the 2 external being ‘embryonic’,</p> <p>• the only known specimen of A-1? stage displays 4 dorsal spines,</p> <p>• the adult specimens display from 4 to 6 spines, the external ones being the smallest.</p> <p>It is worth noting that in A-2? specimens, the external spines are very small and may be overlooked, leading to the wrong identification of only 3 dorsal spines. However, these specimens cannot be confused with Petasobairdia tricornuta Chen in Shi &amp; Chen, 2002 from the Late Permian of South China (Shi &amp; Chen 2002) which is more elongate, larger, and with only 3 spines for specimens of a size slightly larger than the adults of Ceratobairdia wordensis.</p> <p>A significant morphological trend is observed in Ceratobairdia wordensis from the Guadalupe Mountains: whereas the majority of specimens have a relatively smooth surface, several show the development of scattered nodules in the dorsal area of their lateral surface (Fig. 9O–Q). This trend culminates in very rare specimens with the entire lateral surface of the valves covered by nodules (Fig. 9R). This nodular surface is reminiscent of Pustulobairdia Sohn, 1960 but all characters of Ceratobairdia wordensis and the morphological trend observed from smooth to nodular leave no doubt that these specimens belong to Ceratobairdia wordensis.</p> </div>	https://treatment.plazi.org/id/21095E52CF5FC33AFDB853B66356EBF8	Public Domain	No known copyright restrictions apply.

Conversely, the two horny dorsal spines and the three denticles along the dorsal border originally described by Yuan et al. (2009) as of generic significance to the newly erected genus Denticupachydomella rather appear as variations of the morphology and strength of the spines, thus being of specific significance. The diagnosis of Denticupachydomella Yuan in Yuan et al., 2009 is here emended to clarify this issue of generic versus specific characters.</p> </div>	https://treatment.plazi.org/id/21095E52CF51C331FE71568E6294ED63	Public Domain	No known copyright restrictions apply.

Denticupachydomella bellcanyonensis sp. nov. differs from Denticupachydomella multinodosa (Forel in Crasquin et al. 2010) from the Changhsingian (Late Permian) of Sichuan, south-west China (Crasquin et al. 2010) by the presence of a postero-ventral spine and by the organisation of nodules along dorsal and ventral margins at both valves. Herein, the dorso-central shoulder at RV is absent and the surface is covered by nodules. The species from the Late Capitanian of the Penglaitan section (Guadalupuan–Lopingian GSSP) in Guangxi, South China (Zazzali 2016: fig. 13o–p, unpublished material) differs from Denticupachydomella bellcanyonensis sp. nov. by a more elongate carapace and a PB with smaller radius of curvature. The species from the Penglaitan section is also new and has to be described.</p> </div>	https://treatment.plazi.org/id/21095E52CF56C330FE7B5076656AEDFE	Public Domain	No known copyright restrictions apply.
