More than 100 million years ago, a flying reptile called a pterosaur flew over the oceans hunting squid and fish. Much more recently, one of its wing bones was discovered in Brazil, transformed over the eons into a fossil made of a complex assemblage of different chemicals and minerals. And in new research published in […]
