Jurassic fossils from northeastern China reveal morphological stasis in the catkin-yew

Dong and colleagues studied well-preserved plant fossils from the Middle-Late Jurassic Daohugou Bed in eastern Inner Mongolia, northeastern China. These fossils closely resemble the extant catkin-yews Amentotaxus. They provide unequivocal evidence that the catkin-yews have undergone little morphological change over at least ~160 million years.
