E. appetolatus was a Middle Triassic amphibian found in North Central New Mexico in the Tecolotito bonebed. Eocyclotosaurus appetolatus is a genus of amphibian predator that lived in both North America and the‭ ‬British‭ ‬Isles during the early Triassic.‭

Eocyclotosaurus directly translates as‭ ‘‬dawn rounded eared lizard‭’‬. Eocyclotosaurus appetolatus is a recently named Middle Triassic (Perovkan: early Anisian) amphibian (Temnospondyli: Capitosauroidea: Cyclotosauridae) from the Moenkopi Formation of New Mexico.

This disarticulated, attritional assemblage reflects an all-adult population comprising animals in the 1.2 to 2.5 meter length range, and averaging 1.7 meters. The body proportions, and skull and jaw morphology of E. appetolatus was alligator-like, implying that they filled an ecological niche similar to that of some modern crocodilians.

Eocyclotosaurus appetolatus were generalist feeders; they probably took fish in the lakes and rivers that they inhabited and small to medium-sized prey along the shorelines. Data indicate that juveniles grew quickly to sexual maturity in three to four years, after which their growth rate continuously slowed until death.

Survivorship analysis indicates that mortality was probably high in the juveniles, was very low in mid-life, and continuously increased in old age.

Very few Eocyclotosaurus appetolatus reached the ultimate age of perhaps 30 to 40 years. Based on limb bone allometry and stress-strength analysis, juveniles probably had significant terrestrial capability, allowing dispersal of the species, whereas the adults likely formed breeding populations that became increasingly water-bound.
