Specimen: Knightia alta Species: Fossil fish Age: Green River Formation, Eocene Period Location Found: Wyoming, USA Knightia is a prehistoric fish that lived in the fresh water lakes and rivers of North America and Asia during the Eocene epoch, 56 to 33.9 million years ago. They belong to the same taxonomic family as herring and sardines, and likely fed on algae and diatoms, as well as insects and the occasional smaller fish. Knightia fish had heavy scales, small conical teeth and rows of dorsal and ventral scutes that ran from the back of the head to the medial fins. They were schooling fish and are often preserved as fossils still in their shoals, with some specimens even being preserved on top of each other SIMILAR TO SEEN: The image shows an example of the single specimen you will receive.
