About: Ptycholepiformes

An Entity of Type: eukaryote, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Ptycholepiformes are an extinct order of prehistoric ray-finned fish that existed during the Triassic period and the Early Jurassic epoch. The order includes the genera , Ardoreosomus, Boreosomus, , Ptycholepis, and Yuchoulepis. Although several families have been proposed, some studies place all these genera in the same family, Ptycholepididae. Ptycholepiformes had a widespread distribution during the Early Triassic, but were restricted to mainly Europe and North America afterwards. They are known from both marine and freshwater deposits.
