This single genus of synapsid, a mammal-like reptile, populated much of Earth for 5 million years.
An army of mammal-like reptiles dominated vertebrate life.
This would make the creature Mexico's oldest terrestrial vertebrate and the first mammal-like reptile

Summary: TEHRAN (FNA)- During the Triassic period (252-201 million years ago) mammal-like reptiles
called therapsids co-existed with ancestors to dinosaurs, crocodiles, mammals, pterosaurs, turtles, frogs, and lizards.
Its anklebones and vertebral column are also similar to the anatomy of previously known mammal-like reptiles
The changes ill the anatomy of the jaws that took place as mammal-like reptiles
evolved into mammals were characterized by an increase in the size of the temporalis muscle and the dentary bone and a reduction in the size of the postdentary bones (i.e., what was left of the mandibular arch) (figure 4).
The researchers have unearthed exquisitely preserved skulls and bones from mammal-like reptiles
, along with fragments of what may be the oldest dinosaurs yet discovered.
"In fact, the teeth are extremely similar to those of certain mammals and certain very advanced mammal-like reptiles
By noting that the southern beech tree, certain mammal-like reptiles
known as Dicynodonts and other Australian flora and fauna are found only on Gondwana continents, scientists have determined that these continents were once linked .
the scientists say the most significant discoveries among the 3 tons of rock trucked from the Canadian site to Columbia and Harvard are 12 skulls and jaws of mammal-like reptiles
known as Tritheledonts.
