chimera (paleontology)

{{short description|Fossil reconstructed from elements of more than one species}}

{{Distinguish|text = Chimaera, fishes belonging to the order Chimaeriformes}}

In paleontology, a chimera is a fossil that was reconstructed with elements coming from more than a single species or genus of animal. In other words, they are mistakes or sometimes hoaxes made by paleontologists, putting together parts that do not come from the same organism.
