Unidentified Fish Fossils

When I go on trips I sometimes try to find fossils or minerals from that area as a memento. My last trip to Arizona I found this plate in a museum gift shop. Unfortunately, it had no identification label so I do not know its name, location where found, geological formation, or time period. Since it was in a gift shop it must be from an area where fish fossils are commonly found and sold to collectors. Areas I find on the Internet as sources of fish fossils are Green River, Wyoming, Liaoning/Hubai, China, and Ceara, Brazil.


The fish does sort of look like a Dastilbe crandalli found in the Santana Formation of Ceara, Brazil. Fish from that area date to the Lower Cretaceous Period.

The matrix had 2 other fish remains on it. One is of the tail and rear vertebra and the other fossil on the other side of the plate is a jumbo of parts which includes some of the rib bones.
