Figure 21. Comparative plate of teleosauroid crania in dorsal view. A, the teleosaurid Mystriosaurus laurillardi, referred specimen NHMUK PV OR 14781 (holotype of Steneosaurus brevior); B, the aeolodontin teleosaurid Mycterosuchus nasutus, holotype NHMUK PV R 2617; C, the machimosaurid Macrospondylus bollensis, referred specimen NHMUK PV R 5703; D, the machimosaurid Charitomenosuchus leedsi, referred specimen NHMUK PV R 3806; E, the machimosaurin machimosaurid Lemmysuchus obtusidens, holotype NHMUK PV R 3168. All scale bars equal 20 cm. Note, all of these species were previously referred to the genus Steneosaurus, highlighting that taxonomic lumping and paraphyletic genera obscure morphological variation.
