An article published in the journal “PLOS ONE” reports the identification of a new species of cynodont that lived in today’s Argentina about 230 million years ago, in the Late Triassic period. A team of researchers subjected a fossil skull to a high-resolution micro-CT scan to study it in detail and named it Pseudotherium argentinus. Its look made paleontologist Ricardo Martínez compare it to Scrat, a squirrel among the characters in the movie “Ice Age”.
