Was this ancient animal the real father of modern lizards and snakes?
Buenos Aires: New research on a fossil found in Argentina has revealed that it was a lizard-like animal that was found there 231 million years ago. The study was conducted jointly by experts from the United States and Argentina.
Experts believe that this animal may have been the evolutionary ancestor of modern lizards and snakes.
This means that later generations of the same animal, called “Taytalura alcoberi”, gradually evolved into snakes and lizards.
Today it is also the largest group of vertebrates, including more than 11,000 species, including lizards, snakes and hundreds of waterfowl.
The group is named Lepidosaurs, which is thought to have evolved 260 million years ago, but the fossils of ancient Lepidosaurs are in an incomplete and scattered state. Because of this, their evolution became a mystery.
The tetralora alkuberi rakaz consists of a skull which is also quite complete and safe. Its size is only about 30 mm.
Apparently, this skull resembles a special type of lizard found in New Zealand, “Tawatara”.
When the scientists examined it in detail with a CT X-ray scan, they found some features that had not been seen before in any member of the Lepidosaurus group or in the present animal.
Careful analysis revealed that it belonged to an extinct species of Lepidosaurus that had not been discovered before.
The first part of its name, “Tetalora”, is a combination of the words of two tribal languages in South America: “Teta” meaning father. And “Laura” means lizard. That is, the animal was the “father of lizards.”
The discovery of Tatalora is expected to be of great help in learning about the evolution of reptiles.
