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.

Porosphaera globularis Fossil From Spain





This sponge fossil is called Porosphaera globularis from the Cretaceous Period. They were found in the region of Navarra, Spain.

According to the Natural History Museum of the U.K, people sometimes use these fossils as beads in necklaces. One was even found at a Bronze Age burial site with a skeleton from the Higham Marshes of Kent in south east England.

Thanks to Herb for these fossils.
