Subfamily of reptiles

Desmatosuchinae Temporal range: Late Triassic Desmatosuchus Scientific classification Kingdom: Animalia Phylum: Chordata Class: Reptilia Clade: Pseudosuchia Order: †Aetosauria Family: †Stagonolepididae Subfamily: †Desmatosuchinae Huene 1942 sensu Heckert and Lucas, 2000 Genera †Adamanasuchus? †Aetobarbakinoides? †Calyptosuchus? †Chilenosuchus? †Neoaetosauroides? †Olkasuchus †Scutarx? †Desmatosuchini Parker, 2016 †Desmatosuchus †Gorgetosuchus? †Longosuchus †Lucasuchus †Sierritasuchus

**Desmatosuchinae** is a major [subfamily](/source/Subfamily) of [aetosaurs](/source/Aetosaur) within the [clade](/source/Clade) [Desmatosuchia](/source/Desmatosuchia).[1] It is a [stem-based taxon](/source/Stem-based_taxon) defined as all aetosaurs more closely related to *[Desmatosuchus](/source/Desmatosuchus)* than to *[Stagonolepis](/source/Stagonolepis),*[2] *[Aetosaurus](/source/Aetosaurus)*, or *[Paratypothorax](/source/Paratypothorax)*.[1]

The clade Desmatosuchinae has often been restricted to a few closely related aetosaurs with spiny armor, such as *Desmatosuchus*, *[Longosuchus](/source/Longosuchus)*, and *[Lucasuchus](/source/Lucasuchus)*.[3] It was later expanded to include a number of *[Stagonolepis](/source/Stagonolepis)*-like aetosaurs with less specialized armor. Under this more expansive usage, the strongly-supported clade encompassing "traditional" desmatosuchines (*sensu stricto*) was given a new name, **Desmatosuchini**.[1] [Synapomorphies](/source/Synapomorphies) that diagnose this clade can be found in the [osteoderms](/source/Osteoderm). These include tongue-and-groove articulations for lateral plates present in dorsal presacral paramedian plates and large spikes on the lateral cervical, dorsal, and caudal plates.[3]
