The gar fish (Lepisosteidae) is a good example of a "living fossil" - an animal that has not changed much for the last 50 million years. Although the gar has been around since the Cretaceous period, this specimen was recovered from Pliocene to Pleistocene epoch deposits (approx. 11,000 to 5,000,000 years ago) in the Peace River of Florida. This scale is complete with excellent color and definition. From the condition, I would date these specimen as more recent (Pleistocene), but I have no way of accurately dating it.
