4x10cm Fish Fossil Replica, Mesozoic

Bony fish first evolved during the Paleozoic era, over 400 million years ago. This fossil replica represents a mold of a ray-finned fish that died and was buried in the ocean. The thin bones that make up the rays on the fish are easily recognizable, despite the disappearance of the fins themselves. This fossil is great in the classroom for teaching about paleontology and fossil preservation.
