Micro Fish Fossils

This posting shows some very small fish fossils. Some of them are parts of vertebrate and others I am not sure about. The specimens were obtained by Dr. Jim Conkin from material collected on one of his research trips. The fossils were photographed using a microscope set at maybe 15x.
