Ancient Beast Walked Across Pangea to Survive Extinction
Imagine a super-scary cat with giant teeth that lived before dinosaurs!
During a time when most animals died, this cat-like creature named Inostrancevia didn't.
To survive, it walked a super long distance, like going across a whole continent, about as far as from New York to China, to find food and a safe place.
Scientists found its bones in different countries, showing it moved to survive.
It was big and strong with legs bigger than other animals of its time.
This ancient creature was part of a group that was like a mix of mammals and reptiles, showing us how life on Earth has changed over millions of years.
Inostrancevia, a saber-toothed predator, survived the Permian extinction.
It traveled 11,265 kilometers across Pangea to avoid extinction.
Fossils indicate it lived in both Russia and South Africa.
The creature measured 10 feet long and weighed nearly 816 kilos.
Inostrancevia belonged to the Gorgonopsia family, resembling both mammals and reptiles.
