Reports of a"gorgon" mass extinction at the end of the Permian period were greatly exaggerated, new research finds. These bizarre paleo-beasts were thought to have died out along with most other life on Earth at the time, but scientists recently found that some of these so-called gorgons survived into the Triassic period. However, they didn't survive long, making them a"dead clade walking," the team said.
"'Dead clade walking' is a term used in extinction studies that refers to when a group of organisms technically survives a mass extinction, but is so damaged by it that they never recover, and linger on for a little bit before finally disappearing," project co-researcher Christian Kammerer , the research curator of paleontology at the North Carolina Museum of Natural Sciences in Raleigh, told Live Science in an email.
The research was presented Nov. 3 at the Society of Vertebrate Paleontology's annual conference in Toronto and has yet to be published in a peer-reviewed journal.Gorgonopsians — named after the mythical and monstrous Greek gorgons, whose looks could turn people to stone — existed long before the dinosaurs emerged during the Triassic about 240 million to 230 million years ago.
Then, the duo analyzed two additional specimens, likely also members of Cyonosaurus, from the Karoo Basin. Of the three gorgonopsian specimens, two are from sites spanning the Permo-Triassic boundary, and the third is from an early Triassic layer.
