Conodont
Conodonts ( Greek ''kōnos'', " cone", + ''odont'', " tooth") are an extinct group of agnathan (jawless) vertebrates resembling eels, classified in the class Conodonta. For many years, they were known only from their tooth-like oral elements, which are usually found in isolation and are now called conodont elements. Knowledge about soft tissues remains limited. They existed in the world's oceans for over 300 million years, from the Cambrian to the beginning of the Jurassic. Conodont elements are widely used as index fossils, fossils used to define and identify geological periods. The animals are also called Conodontophora (conodont bearers) to avoid ambiguity. Discovery and understanding of conodonts The teeth-like fossils of the conodont were first discovered by Heinz Christian Pander and the results published in Saint Petersburg, Russia, in 1856. The name ''pander'' is commonly used in scientific names of conodonts. It was only in the early 1980s that the first fossil evi ...

Baltoniodus
''Baltoniodus'' is an extinct genus of conodonts. Use in stratigraphy The base of the Dapingian, the third stage of the Middle Ordovician, is defined as the first appearance of ''Baltoniodus triangularis''. The Whiterock Stage refers mainly to the early Middle Ordovician in North America, it is often used in the older literature in a global sense. The Whiterock Stage is given a range from 471.8 (ca. 472) to 462 m.y.a., spanning close to 10 million years. Officially its start is defined by the potentially lowest occurrence of the conodont ''Protoprioniodus aranda'' or ''Baltoniodus triangularis''. ''B. gerdae'' has been found in the early Sandbian Bromide Formation The Bromide Formation is a geological formation in Oklahoma, USA. It is well known for its diverse echinoderm and trilobite fossil fauna. Location The Bromide Formation crops out in the Arbuckle and Wichita Mountains and in the Criner Hills ..., in Oklahoma, USA.

Promissum
''Promissum'' is an extinct genus of conodonts, primitive chordates, that lived during the Upper Ordovician period. A conodont, ''Promissum'' had a primitive mouth under its eyes with mineralized teeth, which are both typical for conodonts. It had a primitive backbone and probably looked like a small eel or large worm, lacking any kind of fins except for perhaps a small one on the tail. It was relatively large for a conodont, reaching about 40 cm (16 inch) in length. Well-preserved specimens were discovered in the Soom shale of South Africa in 1994. ''Promissum'' was probably capable of maintaining a cruising speed, but not of bursts of speed.
