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. Like ginkgo, the catkin-yews are living fossils that provide an important new example of evolutionary stasis.
