Abstract

Paraphyllanthoxylon utahense, sp. nov., is described from the Cedar Mountain Formation and compared with similar fossil and modern woods. Fossil angiosperm woods from the Early Cretaceous are of great interest because very few have been reported from strata of this age. This species demonstrates that the angiosperms had developed many of their modern characteristics by Early Cretaceous time.
