Platycrinites are an extinct genus of Paleozoic stalked crinoids belonging to the family Platycrinitidae.
These stationary upper-level epifaunal suspension feeders lived during the Devonian, Permian and the Carboniferous periods, from 376.1 to 259.0 Ma.
These moderate sized extinct crinoids had a columnar stem with a twisted pattern. On top of the stem was a calyx with a number of feather-like arms.
Fossils of this genus have been found in the Devonian of Germany, in the Carboniferous of Australia, Canada, China, Ireland, United Kingdom, United States. As well as in the Permian of Australia, Canada, Indonesia, Oman and United States.
