Dermatemydidae
Taxonomy
Dermatemydidae was named by Baur (1888) [incorrectly credited by someone (Carrano?) to Gray 1870]. It is extant.
It was assigned to Cryptodira by Lydekker (1889); to Chelydroidea by Baur (1893); to Cryptodira by Hay (1908); to Cryptodiri by Jaekel (1911) and Perrier (1928); to Emydoidae by Hay (1930); to Testudinoidea by Estes (1964) and Kuhn (1966); to Testudinata by Estes and Berberian (1970); to Metachelydia by Khosatzky and Mlynarski (1971) and Mlynarski (1972); to Cryptodira by Zittel (1890), Gadow (1898), Kuhn (1946) and Thurmond and Jones (1981); to Trionychoidea by Gaffney (1975) and Carroll (1988); to Testudines by Frank and Ramus (1996); to Kinosternoidea by Joyce et al. (2004), Knauss et al. (2011), van Dijk et al. (2014) and Bourque et al. (2015); and to Pandermatemys by Joyce and Bourque (2016).

Diagnosis
Reference | Diagnosis | |
---|---|---|
O. P. Hay 1908 | Plastron in most cases suturally articulated to the carapace; with an entoplastron, but without mesoplastra; the anterior and posterior lobes usually reduced in size. Nuchal bone with or without costiform processes. Neural bones reduced in number, except in Baptemys; some of the hinder costal bones meeting their fellows in the midline, except in the same genus. Peripheral bones in 10 or 11 pairs. Plastron furnisht with a full series of inframarginal scutes, except in Basilemys. The scutes of the anterior lobe perhaps in all cases modified from the condition seen in Baina. Caudal vertebrae in all the known forms procoelous. The hinder lobe of the plastron often with a scar for the pelvis, but the latter never suturally joined to the plastron. Temporal region not rooft over and no parieto-squamosal arch. Quadrate notcht behind for the stapedial rod. | |
E. Perrier 1928 | Queue courte, moindre que la moitié de la carapace; tête complètement rétractile, grande, recouverte d'une peau non divisée en écailles, sauf un bouclier corné sur le nez ; carapace fortement déprimée, tricarénée, recouverte par des plaques cornées typiques; série des plaques osseuses neurales non continue, les costales postérieures se rejoignant sur la ligne médiane; plaques cornées du plastron séparées des marginales par des inframarginales. Tortues de marais, s'enfonçant dans la vase, vivant de poissons, de crustacés et de mollusques. | |
J. R. Bourque et al. 2015 | Plastron suturally united to the carapace;
entoplastron present (Appendix S1:Ch. 28); plastral lobes reduced; nuchal with or without costiform processes; three to five pairs of inframarginal scutes present (Appendix S1:Ch. 30)(Hay, 1908); temporal region emarginated from behind, separating squamosal from parietal and postorbital; frontals enter orbital margin; maxilla does not meet quadratojugal; quadrate does not surround stapes; no foramen present in prootic for temporal artery; dentary expanded posteriorly over much of external surface of jaw; only one biconvex centrum in cervical vertebrae; eighth centrum doubly concave anteriorly; caudal vertebrae procoelous; paired pubes and ischia meet ventrally, but pubic and ischiadic symphyses are widely separated; trochanteric fossa of femur widely open (Iverson and Mittermeier, 1980); axillary buttress contacts C1 (Appendix S1:Ch. 25) (Meylan and Gaffney, 1989); carapace smooth or with some crenulated sculpturing; club-shaped terminus of axillary buttress; C3 spans P5 dorsally (Hutchison and Bramble, 1981); distal C1 terminates in P3 (Appendix S1:Ch. 7); two suprapygals present (Appendix S1:Ch. 10); lack of distinct anterior musk duct groove (Appendix S1:Ch. 15); loss of extragular and pectoral scutes; marginals not encroaching upon suprapygals or costals; abdominals contribute to axillary notch (Appendix S1:Ch. 34); femoral–humeral sulcus arched anteriorly; reduction or loss of foramen stapedio-temporale;medial triturating ridge of dentary curving laterally anteriorly and contacting lateral ridge to form a pocket. |
