Hatcherichnus is a trace fossil ichnogenus from the Upper Jurassic Morrison Formation of western North America and Europe. [1] The type material is from the Salt Wash Member of the Morrison Formation in southeastern Utah, although the name is in honor of John Bell Hatcher, who illustrated a referred specimen from the Morrison of Garden Park, Colorado, in 1903. The type specimen consists of natural casts of the manus and pes, plus a tail trace, preserved in the roof of a uranium mine. [2] These traces are believed to be those of swimming or floating neosuchian crocodyliforms. [2]
