Conodonts were tiny fish-like animals that were very abundant in the shallow seas. The animals were about 1/4 inch in length and had no hard parts except for their teeth. Conodont teeth are very common fossils in the Ordovician, Silurian, Mississippian rocks in Kentucky. Conodots are also numerus in India Conodont teeth fossils are microscopic and are studied by micropaleontologists. They became extinct during the Triassic Period. They aid geologists and paleontologists in determining the age of many sedimentary rocks. Fossil impressions of strange animals found recently in Montana contained groups of conodonts. They appeared to be embedded in the digestive organs of a small, primitive marine animal. Five or six kinds of conodonts were present in one individual. |
