Additional Plants Outlived The World’s Pronounced Mass Extinction That Contemplated. A congregation of approximately 255-million-year-old fossils indicates that three paramount plant categories subsisted earlier than formerly contemplated and survived through mass extinction that erased more than 90 percent of Earth’s marine sort and approximately 70 percent of land vertebrates.

The fossils fend off the premature records of these plant groups by around 5 million years.  Study coauthor Benjamin Bomfleur, a paleobotanist at the University of Münster in Germany said that it’s not an ordinary 5 million years, it’s those 5 million years that traverse Permian-Triassic boundary. The discovery appends to increasing list of land plants that outlived the calamity known as the Great Dying, the world’s most extensive mass extinction which took place about 252 million years ago at the end of the Permian Period.

Bomfleur and his colleagues discovered the contemporary fossils in desert rock outcroppings proximate to the Dead Sea in Jordan. Paleontologists have been foraging those rock formation for decades. He said that they discover new fossils every time they go.

When these fossils were formed the region had a tropical climate but with extended dry spells. That environment was not good for modeling fossils. However, unanticipated these fossils are extraordinarily well conserved, Bomfleur says.

He and his compatriots were able to douse the rocks with an acid to withdraw waxy plant cuticles buried within. The cuticle conserves a mold of microscopic characteristics on the surface of fronds or leaves and those ingredients assisted the scientists recognize the plant species more precisely.
