Conodonts
fossil remains of animals whose classification is uncertain. They have been found in deposits from the Cambrian through the Triassic. Upper Cretaceous types have also been described. Conodonts have been found in a variety of forms—toothlike, comblike, or leaflike—with dimensions ranging from fractions of 1 mm to 2–3 mm. They are composed of calcium phosphate. They evidently were arranged in the bodies of the living organisms in the form of intricate complexes known as apparatus. Conodonts are important for the stratigraphy of Paleozoic deposits.
