This is a series of skulls and front leg fossils of organisms believed to be ancestors of the modern- day horse. Usually only a portion of an organism is preserved as a fossil, such as body fossils (bones and exoskeletons ), trace fossils (feces and footprints), and chemofossils (biochemical signals). This fossil record shows that many kinds of extinct organisms were very different in form from any now living. Fossils of horse skulls and legs across different species show adaptations over time, like a reduction in toes and elongation of legs. Comparisons of homologous structures across species, such as fins and flippers, provide evidence that organisms evolved from a common ancestor and adapted to different environments over generations.
