Fossils of plants that survived the extinctionScience News

A collection of roughly 255-million-year-old fossils suggests that three major plant groups existed earlier than previously thought, and made it through a mass extinction that wiped out more than 90 percent of Earth’s marine species and roughly 70 percent of land vertebrates.

The fossils, described in the Dec. 21 Science, push back the earliest records of these plant groups by about 5 million years. “But it's not just any 5 million years — it's those 5 million years that span the Permian-Triassic boundary,” says study co-author Benjamin Bomfleur, a paleobotanist at the University of Münster in Germany. The find adds to the growing list of land plants that survived the catastrophe known as the Great Dying, the world’s greatest mass extinction, which occurred about 252 million years ago at the end of the Permian Period.
