Paleontology

Paleontologists report paired discoveries from China that rewrite the early chapter of bony fish evolution and, by extension, the evolutionary lineage leading to all living vertebrates including humans.

A team led by the University of Chicago has named Spinosaurus mirabilis, a scimitar-crested, fish-eating theropod found 500–1,000 km from the nearest ancient sea, reshaping what scientists know about where spinosaurs lived.
