However, ecosystems 150 million years ago also included many small, fragile species. A recent study in Current Biology provides fresh details about how two small pterosaurs from Germany’s Solnhofen Limestone beds met their end during intense tropical storms. Meet Baby Pterosaurs “Lucky I” and “Lucky II”Researchers from the University of Leicester identified two specimens, called “Lucky” and “Lucky II.” Both are members of Pterodactylus, the first pterosaur described by science. “For centuries, scientists believed that the Solnhofen lagoon ecosystems were dominated by small pterosaurs,” said Smyth. Larger pterosaurs were more likely to survive these storms or perish on the surface, leaving fewer opportunities for their fossils to be preserved.
