Extinct genus of reptiles

Longosuchus Temporal range: Late Triassic Mounted skeleton Scientific classification Kingdom: Animalia Phylum: Chordata Class: Reptilia Clade: Pseudosuchia Order: †Aetosauria Family: †Stagonolepididae Subfamily: †Desmatosuchinae Genus: †Longosuchus Hunt & Lucas, 1990 Species †L. meadei (Sawin, 1947) (type)

***Longosuchus*** (meaning "Long's crocodile") is an [extinct](/source/Extinct) [genus](/source/Genus) of [desmatosuchin](/source/Desmatosuchinae) [aetosaur](/source/Aetosaur) from the Late [Triassic](/source/Triassic) of [North America](/source/North_America).[1][2] Reported fossils from Morocco are likely misidentified scutes of a [paratypothoracin](/source/Paratypothoracini) aetosaur.[3] *Longosuchus* measured about 3 metres in length.[1]

## Taxonomy

Restoration

*Longosuchus* was originally named as a species of *[Typothorax](/source/Typothorax)*, *T. meadei*, in 1947 on the basis of skeletal remains from the Otis Chalk quarries in Howard County, western Texas. Hunt and Lucas (1990) recognized *T. meadei* as generically distinct from the type species of *Typothorax* and renamed it *Longosuchus* in honor of Robert Long.[4][5]
