Dilophosaurus amidst Ginkgos

A hungry, carnivorous dinosaur theropod of the genus Dilophosaurus hunts for her next meal in a valley forest of non-flowering plants of the genus Ginkgo 180 million years ago in what is today North America.

The Ginkgo first emerged 270 million years ago and it is the oldest genus of tree still living today--a "living" fossil. It has no close living relatives. The Ginkgo is very tolerant of extreme conditions including manmade pollutants, which ironically makes this primeval plant well-suited for today's urban environments.
