Fish Fossils

Fish fossils are a good indicator of what type of species lived at that geologic time period. Many fish from worldwide localities have been fossilized and the environment they lived in. Such as the ocean and inland seas and lakes. Fish first appear on the planet at the beginning of the devonian period (some 400 million years ago). They are one of the first vertebrate animals to populate our planet and are still with us today. They pre-date the rise of the reptiles, dinosaurs, and birds etc. Fossil fish are sought by fossil collectors and make great looking display fossils.
