Not all prehistoric mammals needed to scurry to avoid dinosaurs with whom they shared the planet in the Jurassic age. Some just glided, according to research published on Thursday.

Fossils of two extinct mammals that lived in what is now China some 160 million years ago revealed the outlines of wing-like membranes joining the rodent-like animals’ front and hind limbs, a team of US and Chinese scientists wrote in the journal Nature.

“With long limbs, long hand and foot fingers, and wing-like membranes for tree-to-tree gliding, Maiopatagium furculiferum and Vilevolodon diplomylos are the oldest known gliders in the long history of early mammals,” said a statement from the University of Chicago, whose researchers took part in the study.

It was not until more than 100 million years later that bats, which use powered flight like birds, and more gliding mammals appeared, following the dinosaurs’ demise.
