Palaeontology: Modern look for ancient lamprey
Philippe Janvier1
Abstract
It was once thought that lampreys evolved from armoured jawless vertebrates. But a recently discovered lamprey fossil dates from the twilight age of their supposed ancestors, and looks surprisingly modern.
Most living vertebrates have jaws. Such creatures comprise about 51,000 species ranging from sharks to four-legged land vertebrates.
