by Scientists have discovered the fossil of a tiny mammalian in mouse that lived in the time of the dinosaurs in the Chilean Patagonia.
“Yeutherium Pressor” weighed between 30 and 40 grams (about an ounce) and lived in the upper Cretaceous period about 74 million years ago.
It is the smallest mammal that was ever found in this region of South America and goes back from the time when it was part of a continental land mass that is known as Gondwana.
The fossil consists of “a small piece of pine with a molar and the crown and the roots of two other molars,” said Hans Puschel, who cited the team of scientists from the University of Chile and Chiles Millennium Nucleus Research Center for early mammals.
The discovery was published this month in the British Scientific Journal Proceedings of the Royal Society B. B.
The researchers found the fossil in the Rio de Las Las Las Chinas Valley in the Magallanes region in Chile, about 3,000 kilometers south of Santiago.
“Yeutherium Pressor” despised his resemblance to a small rodent. He was a mammal that laid eggs like the platform or worn his young in a bag like Kangaroos or Opossum.
The shape of his teeth suggests that she probably had a diet with relatively hard vegetables.
Just like the dinosaurs with whom it was with, the tiny mammalian abruptly existed about 66 million years ago at the end of the Cretaceous period.
