Extinct genus of reptiles

Apachesuchus Temporal range: Late Triassic, late Norian Scientific classification Kingdom: Animalia Phylum: Chordata Class: Reptilia Clade: Pseudosuchia Order: †Aetosauria Family: †Stagonolepididae Subfamily: †Typothoracinae Genus: †Apachesuchus Spielmann and Lucas, 2012 Species †A. heckerti Spielmann and Lucas, 2012 (type)

***Apachesuchus*** is an extinct [genus](/source/Genus) of [aetosaur](/source/Aetosaur) from the [Late Triassic](/source/Late_Triassic) of [New Mexico](/source/New_Mexico). It is only known from several paramedian [osteoderms](/source/Osteoderm) discovered in [Quay County](/source/Quay_County%2C_New_Mexico) in eastern New Mexico. This area belongs to the late [Norian](/source/Norian)-age Quay Member of the [Redonda Formation](/source/Redonda_Formation). Unique among aetosaurs, its osteoderms are nearly completely smooth, without strong pits or grooves.[1] The left dorsal paramedian has a relatively high width-to-length ration (about 3.25), suggesting that *Apachesuchus* is a wide-bodied aetosaur within the [clade](/source/Clade) [Typothoracinae](/source/Typothoracinae).[2]

The [holotype](/source/Holotype) and referred material of *Apachesuchus* were initially described by Heckert et al. (2001), who assigned them to the South American aetosaur *[Neoaetosauroides](/source/Neoaetosauroides)*.[3] However, this comparison was based on *Neoaetosauroides* osteoderms which had been overprepared, removing their surface texture. In their 2012 monograph on vertebrates of the Redonda Formation, Justin Spielmann and Spencer Lucas decided that the material reported by Heckert et al. was sufficiently distinct to be recognized as a new genus and species. They named it ***Apachesuchus heckerti***, in honor of Andrew Heckert.[1]
