Paleontologists have recently discovered the remains of an animal that lived 230 million years ago, and it's very similar to Scrat, the squirrel from the Ice Age movies. It is the first specimen of this species ever to be discovered, so they had to name it and eventually choose Pseudotherium argentines (False Theria from Argentina).
The skull was repaired by paleontologists under the direction of dr. Ricardo Martínez, a researcher at the Institute and Museum, discovers the natural sciences of the University of San Juan (IMCN). He found it at the famous place Ischigualasto (province of San Juan in northwestern Argentina). He found that the appearance of the mammal was actually very similar to Scrat:
"The new species has a very long, flat and shallow muzzle, and its long fangs are almost at the top of the muzzle, so the similarity [to Scrat] is enormous. […] At some point I thought of calling it Scrat.
Together with Rachel Wallace and Timothy Rowe (The Jackson School of Geosciences at the University of Texas, Martinez, examined the Skull of Mammalian Morph (a relative of mammals) and published her work in Plos One Martinez not only discovered two different species in one place, but three – the third was the femur of the first and a single relatives of stockpetid dinosaurs who found in this place
The study provides some details about the Pseudotherium: it lived in a warmer environment than it was today, was about 25 cm long and fed on small animals and insects, but definitely not on acorns.  As far as the long fangs are concerned, Martinez theorises. It is thought that they were used either to attract women, if this was the skull of a man, or to pin down and catch his prey. The problem of finding out more about this animal is that only one specimen is available for the study:
"If many individuals had to be analyzed, one could determine if variability existed and could assume that males and females have different lengths of fangs. ".
Two "Scrats" from two completely different epochs
Years later, researchers Guillermo Rougier, Sebastián Apesteguía and Leandro Gaetanoier discovered the Remains of an animal similar to that excavated by Martinez. Cronopio was found in La Buitrera, a town on the Río Negro.
This time it had a size of 10-15 cm and was called Cronopio dentiacus. However, research has shown that Pseudotherium argentinus is 231 million years old, but Cronopio is 95 million years old.
Dr. Ricardo Martínez concluded that the study of the two specimens looks like " restores the phylogenetic bonds of Scrat."
