Pycnodontidae indet. (Fig. 6 D-F)

DESCRIPTION

A second pycnodontiform taxon is represented by beanshaped to suboval teeth with a transverse groove or depression and one or two lateral tubercles (Fig. 6 D-F). This taxon is also present in the Purbeckian facies of Cherves-de-Cognac, and has been described as “tooth morphotype 7” by Pouech et al. (2015: fig. 8b). A very similar and likely congeneric form has also been described from the Wealden facies of southern England as Coelodus sp. (Sweetman et al. 2014) then assigned to Ocloedus sp. (Sweetman 2016) . However, the English material includes nearly complete vomerine dentitions with three tooth rows (Sweetman et al. 2014: fig. 10e), indicating that this unnamed species does not belong to either Coelodus or Ocloedus, which both have five vomerine tooth rows (Poyato-Ariza & Wenz 2002). Numerous ventral keel scales showing contacting spines of anteroposteriorly increasing size, can be assigned to Pycnodontidae (see Poyato-Ariza & Wenz 2002; Sweetman et al. 2014).
