Origin: A borrowing from Latin. Etymon: Latin Platycrinidae.

Etymology: < scientific Latin Platycrinidae, family name ( T. Austin and T. Austin Monogr. Recent & Fossil Crinoidea(1843) 6) < Platycrinus , genus name ( J. Phillips Illustr. Geol. Yorks.(1836) ii. 204, after earlier Platycrinites : see platycrinite n.) + -idae (see -id suffix³). Compare earlier platycrinoid n., platycrinite n.

Palaeontology. rare.

A. n.

An extinct crinoid of the Palaeozoic family Platycrinidae (or Platycrinitidae), typically having broad, flattened radial and basal plates.Since the genus name Platycrinites has priority over Platycrinus, the family name Platycrinitidae is strictly more correct.
