The order Conodontophorida is a group of extinct jawless vertebrates that lived during the Paleozoic era. Some synonyms for this order include Conodonts, Conodonts-phorida, Conodont Animals, and Conodont Vertebrates. These synonyms are used interchangeably to refer to the characteristic teeth of the Conodontophorida, which are used to identify them in the fossil record. Conodont fossils have been found in rocks all over the world and are important for understanding the evolution of early vertebrates. Despite their small size and lack of a recognizable body plan, Conodontophorida played an important role in the ecosystems of their time and left behind a significant legacy in the fossil record.
