The bones of over 10,000 years oldalso include specimens such as the macraucheniaa conspicuous animal with a small trunk, like that of the tapirs, or the toxodontsanimals similar to the current hippopotamus, reported the CTyS Scientific Journalism Agency of the National University of La Matanza (Unlam).
The team of paleontologists managed to recover the materials before they were washed into the riverbed and lost forever. “On many occasions, you find bones that the meteorological agents were breaking and it is difficult to identify the species or the genus. In this case, the fossils are very well preserved, which makes it easier for future researchers who want to analyze the materialAguilar pointed out.
The doctor Luciano Brambillaa researcher at the Center for Interdisciplinary Studies of the National University of Rosario (UNR), is analyzing the great diversity of remains found, together with the San Pedro team.
“The set of assembled fossils shows part of the extinct South American fauna from the end of the Pleistocenewhich highlights the giant and medium sized animals. Among them, the lazyjust like the glyptodonts of the group found, originated from a common ancestor that lived more than 60 million years ago and evolved to reach the forms found here in San Pedro”, explained Brambilla.
Meanwhile, the UNR researcher explained that, although much remains to be said about the evolution and interactions of these animals, “The findings of these fossil assemblages allow progress in this direction, recognizing the components of that lost fauna”.
