Neuropteris

A four-foot-tall seed fern from the genus Neuropteris grows near waters edge among towering tree-like plants from the genus Lepidodendron over 300 million years ago in what is today North America. On the lower left are "roachoids," primitive ancestors of modern cockroaches from the Superorder Dictyoptera, and on the right is a giant millipede from the class Diplopoda.

Now extinct, Neuropteris thrived for most of the Carboniferous, its distinctive leaves making up some of the most common fossils from this period.
