More turtles with temporal fenestrae
Yesterday we looked at several turtles with a lateral temporal fenestra. Today a few more are presented including Baena and Kayentachelys, turtles recently added to the large reptile tree (LRT, 1201 taxa).
These two extinct turtles
nest between basalmost forms and extant turtles.
By convergence
several turtle clades (Fig. 3) developed various skull fenestrae, including soft-shell turtles beginning with Arganaceras (not sure if it’s a turtle or not yet) and Odontochelys.
Among the most striking of the fenestrated turtle skulls
are the [cryptodire = straight neck] common Eastern box turtle (genus: Terrapene, Fig. 4) and the [pleurodire = side neck] matamata (genus: Chelus, Fig. 5). It’s difficult to label these two ‘anapsids’ based on their skull morphology, but that’s the traditional label.
