Summary

Description

Cyrtaspidichthys sculptus (Bryant, 1933) fossil fish from the Devonian of Wyoming, USA. (CMC VP collection, Cincinnati Museum of Natural History and Science, Cincinnati Museum Center, Cincinnati, Ohio, USA)

This species is also known as Crytaspis sculptus and Protaspis sculptus.

This Devonian fossil jawless fish from Wyoming is an agnathan with a bony exoskeleton. All agnathans are jawless - they represent the oldest-known, ancestral fish group. Agnathans are still alive today and include the hagfish. Early agnathans with bony exoskeletons are often called ostracoderms. The fossil shown here is a rare specimen of Cyrtaspidichthys - the dorsal (upperside) surface is exposed. Cyrtaspidichthys has a dorso-ventrally compressed body, consistent with a benthic swimming lifestyle.
