Ancient ‍’Saber-Toothed’ Predator Rewrites Mammal Evolution ​History

A groundbreaking‍ fossil revelation⁢ in Spain has sent ripples through⁤ the scientific community, forcing a re-evaluation of early ⁢mammal evolution. The find, a previously‍ unknown species of gorgonopsian, an⁢ extinct group of⁣ therapsids – the⁤ lineage that eventually gave rise to all⁣ mammals – dates back‍ an astonishing 270 million years. These remarkable creatures, which resembled ⁣dog-like reptiles,⁣ were⁤ characterized ⁢by their saber-like canine ⁤teeth, making them the‍ oldest known saber-toothed predators. ‍ Paleontologists ⁣believe this fossil sheds light on a crucial missing link, offering ‌insights into the evolutionary journey of mammals. Ancient dog-like predator identified as oldest known mammal relative The ⁢exceptionally well-preserved skeleton, found in mallorca, Spain, includes fragments of bone, vertebrae, ribs, and importantly, a near-complete femur. This provides valuable ⁢clues about the animalS locomotion,⁣ revealing a gait that was‌ in between that of reptiles‍ and mammals. This​ groundbreaking discovery, published in the journal‍ *Nature Communications*, ‍challenges previous ‌understanding of mammalian​ evolution. (Image: X) “While the fossil appears⁢ to be‍ about 270 million years old,the mammal might have been ⁤alive over 30 million‌ years ago,” explains study​ author Kenneth D. angielczyk. ‌ This significant gap​ in the fossil ​record,⁤ termed the “ghost ⁣lineage”, adds another layer of complexity to the puzzle of mammalian evolution.

An Ancient Supercontinent

The discovery ⁤not only elucidates mammalian evolutionary history but also provides insight into the ancient supercontinent of Pangaea. Gorgonopsians are believed⁣ to ⁤have inhabited various parts of this vast landmass,⁣ including the Mediterranean islands. (Image: X) Researchers estimate that this remarkable predator was roughly the size of⁣ a ​dog, making ⁤it one of the largest ⁢land predators of ⁣its time. The exceptional preservation of its fossil‍ remains has provided scientists with a rare glimpse‍ into the dawn ‍of mammalian history. Before the reign ​of dinosaurs, an era of ⁣ancient mammal ​relatives thrived. These ‍creatures, though, looked ‍vastly different from the mammals we certainly ⁣know ⁣today, ⁣according ‌to Dr. Angielczyk.
