Teleosauridae Geoffroy Saint-Hilaire 1831 (Zoological Code)

Teleosauridae Geoffroy Saint-Hilaire 1831: 41 (PhyloCode)

RegNum registration number 800.

Type genus: Teleosaurus Geoffroy Saint-Hilaire, 1825 .

Etymology

‘The family of Teleosaurus ’. The stem Teleosaur - is based on the genus Teleosaurus . - idae, is a Latin patronymic suffix, introduced into zoological nomenclature, as -idae, by Kirby (1815: 88). Under Article 29.2 of the Zoological Code, the suffix - idae denotes a family rank within the family-group.

Geological range

Early Jurassic (early Toarcian) to Late Jurassic (early Tithonian) ( Johnson et al. 2020a).

PhyloCode phylogenetic definition

The largest clade within Teleosauroidea containing Teleosaurus cadomensis ( Lamouroux 1820) but not Machimosaurus hugii ( von Meyer 1837) . Definition from Johnson et al. (2022b).

Zoological Code diagnosis and PhyloCode diagnostic apomorphies

Teleosauroid crocodylomorphs with the following unique combination of characters (4): anterior and anterolateral premaxillary margins are oriented anteroventrally and extend ventrally (125.1); anterior margin of the supratemporal fossae is noticeably inclined anterolaterally (195.1); postorbital extensively forms part of the orbit ventral margin (283.1); palatal ramus of the maxilla takes part in the anteromedial border of the supratemporal fenestra (349.1).

Composition

An unnamed clade composed of the unnamed Chinese teleosauroid, Indosinosuchus , and Mystriosaurus ; Teleosaurinae (comprising Platysuchus and Teleosaurus ); and another unnamed clade (see the Steneosauridae section above for the rationale as to why) composed of Seldsienean (note we have submitted an application to the ICZN to make the type species of Seldsienean the new type species of Steneosaurus ; Young et al. in review a), and Aeolodontini (comprising Aeolodon , Bathysuchus , Mycterosuchus , and Sericodon ).
