Summary
| Description |
Dunkleosteus terrelli (Newberry, 1873) - fossil fish skull (cast) from the Devonian of Ohio, USA. (public display, Field Museum of Natural History, Chicago, Illinois, USA) The placoderms are a group of extinct, mostly predatory fish that existed during the Middle Paleozoic (Silurian and Devonian). The most famous placoderm was Dunkleosteus, which was named after David Dunkle, an Ohio paleontologist. It was not a shark - it had a bony skull, a neck joint, and remarkably, the jaws lacked true teeth. Instead, the jawbones were sharp-edged and pointed. Classification: Animalia, Chordata, Vertebrata, Placodermi, Arthrodira, Dunkleosteidae Stratigraphy: Cleveland Shale Member, upper Ohio Shale, Famennian Stage, upper Upper Devonian Locality: Rocky River Valley, Cleveland urban area, western Cuyahoga County, northeastern Ohio, USA See info. at: <a href="https://wiki.riteme.site/wiki/Dunkleosteus" rel="nofollow">wiki.riteme.site/wiki/Dunkleosteus</a> |
