Thecodontia

Heavily armored quadruped reptile North American stagonolepidae aetosaur Binary nomenclature related to Loricata One of the largest former thecodonts And a massive menacing appearance But a carnivore crurotarsan not Actually a docile herbivore Blunt, bulbous, curved teeth Perhaps omnivorous insectivore Homodont sheath-covered dentition Toothless beak and shovel snout Slender, forked, expanded premaxillae Large mandibular fenestra Its bite reminiscent of ornitischians It lived in muddy water areas Near rivers, lakes and waterways Digging up soft vegetation Median and lateral scutes carapace Unique aetosaur with five rows of spines Desmatosuchus spurensis, the archosaur spur

Chalishevia, Fugusuchus Garjainia, Guchengosuchus Vjushkovia, Shansisuchus genera Erythrosuchidae The top of the food chain in the early-middle Triassic kannemeyeriid dicynodonts were their main prey Hiding in the vegetation ambushing and scavenging a massive gigantic skull long half the size of their body Potent jaws and teeth which put fear even in the eyes of the other predators Erythrosuchus africanus A primitive crocodile vermillion digitigrade clade Archosaurformes a Thecodont no more

A holotype with intergumentary appendages Projecting from the back of its skeleton Seven, radiating in a fanlike pattern Spaced close together, tips unpreserved Proximal straight section divided Into three longitudinal lobes Raised rugae and deep interstices Not unlike a bone-made rosary bead Interior flange up to the tip of the distal section Ridged and separated by a grooved axis Projecting perpendicular or curving in S-shapes Vertebrae spines to anchorage points Resembling raised knobs, slightly convex Tubular in life, like feathers into a folicle Long scales, pseudosuchian, proto-archosaurian A gift of the lacustrine fluvial Madygen

Thick armoured scales ran down its body Heavy body armour to repel carnivores Small headed, slowly moving browser A long intestine to digest vegetation Beak-like tip that arched upwards Peg-like teeth to uproot plants Snout-like unusual structure of the skull Allowing to dig through the undergrowth Chewing tough cycads, horsetails and ferns Fossil remains found in sandstones In Lossiemouth and Krasiejów deposits Some species stratigraphically younger Like the Stagonolepis Olenkae specimens The genus Aetosauroides as a junior synonym Aetosauroides Scagliai and Subsulcatus Sequential studies to smaller specimens Proposed they belonged to the Robertsoni The Wellesi specimen was called Calyptosuchus Now they belong to the same monotypic genera And are restricted to the Carnian stage
