Teleosaurinae Geoffroy Saint-Hilaire 1831 (Zoological Code)

Teleosaurinae Bonaparte 1838: 123 (PhyloCode)

RegNum registration number 799.

Type genus: Teleosaurus Geoffroy Saint-Hilaire, 1825 .

Etymology

‘Pertaining to Teleosaurus ’. The stem Teleosaur - is based on the genus Teleosaurus . - inae, is a Latin feminine plural suffix for ‘pertaining to’. Under Article 29.2 of the Zoological Code, the suffix - inae denotes a subfamily rank within the family-group.

Geological range

Early Jurassic (early Toarcian) to Middle Jurassic (Bathonian) ( Johnson et al. 2020a).

PhyloCode phylogenetic definition

The largest clade within Teleosauroidea containing Teleosaurus cadomensis ( Lamouroux 1820) but not Aeolodon priscus (von Sömmerring 1814) . Definition from Johnson et al. (2022b).

Zoological Code diagnosis and PhyloCode diagnostic apomorphies

Teleosauroid crocodylomorphs with the following unique combination of characters (6): between 50–65% of the premaxilla total length is posterior to the external nares (shared with Machimosauridae ) (127.1); frontal–postorbital suture lower than the intertemporal bar (236.1); five alveoli per premaxilla (577.4); dorsal osteoderms ornamented with small round-toellipsoid pits that are very densely distributed (840.0); presacral osteoderms partially embrace the vertebrae laterally (847.1); transverse expansion of the thoracic dorsal osteoderms, with the transverse width 1.5-to-2.0 times greater than the anteroposterior length (856.1).

Composition

Platysuchus and Teleosaurus .

Comments

Authorship: While the nomen Teleosaurinae was first used by Bonaparte (1838: 123), as Teleosaurina , under the Zoological Code Geoffroy Saint-Hilaire 1831 is the nominal authority. The nominal author of a family-group is the author who first erected a family-group taxon that is valid (in fulfilment of Article 11), and in accordance with the Zoological Code Principle of Coordination applied to family-group names (Article 36.1). However, under the PhyloCode, Bonaparte (1838) is the nominal authority.
