Description: | Specimen of a fossil fish, Acentrophorus varians Kirkby, collected from the Concretionary Limestone of Late Permian, Zechstein (Durham Province), EZ2 age from Fulwell Hill, Sunderland, Tyne and Wear (NE England). Collected by James Walter Kirkby.
Acentrophorus varians was a small fish, about the same size as a sardine. It lived in the Zechstein sea (a warm tropical sea), 250 million years ago. Acentophorus was adapted to survive in the very salty water. It was probably a scavenger and fed from the remains of other dead fish. It had tiny sharp, pointed teeth for tearing flesh, but was one of the smallest fish in the sea at that time and was therefore probably not a predator.
The specimen was found in Tyne and Wear.
It is from the Permian period (290 - 248 million years ago) | Publisher: | Tyne & Wear Archives & Museums | Subjects: | Classification: Chordata Kirkby Semionotiformes Pisces James Walter Neopterygii Semionotidae Actinopterygii Osteichthyes | Temporal: | Permian period (290 - 248 million years ago) | Source: | Tyne & Wear Archives & Museums | Identifier: | http://www.twmuseums.org.uk/geofinder/se... | Go to resource |
