Still Waters Posted July 21, 2021 #1 Share Posted July 21, 2021 A finger-sized fossil from 308 million years ago unearthed in the United States gives tantalizing clues to the habits of tiny dinosaur-like creatures that may be the forerunners of reptiles, researchers revealed Wednesday. The new species is a microsaur—small, lizard-like animals that roamed the Earth well before proper dinosaurs made their appearance. The find sheds important light on the evolution of different animal groups, including amphibians and reptiles, scientists wrote in the journal Royal Society Open Science. Microsaurs lived during the Carboniferous period, when the forebears of modern mammals and reptiles, called amniotes, first appeared. https://phys.org/news/2021-07-fossil-reveals-burrowing-lifestyle-tiny.html https://royalsocietypublishing.org/doi/10.1098/rsos.210319 1 1 Link to comment Share on other sites More sharing options...
