The eleventh Archaeopteryx

Researchers from Ludwig-Maximilians-Universitaet (LMU) in Munich report the first description of the geologically oldest fossil securely attributable to the genus Archaeopteryx, and provide a new diagnostic key for differentiating ...

A Middle Jurassic monster put in its taxonomic place
