What is another word for conodont?
Pronunciation: [kənˈɒdɒnt] (IPA) 
Conodonts are an extinct group of small, tooth-like structures that are found in ancient marine sedimentary rocks. They are important biostratigraphic indicators, meaning they help geologists to date the rocks in which they are found. Some synonyms for conodont include "conodontophore," "conodont-bearing formation," and "conodont zone." These terms all refer to the same basic idea. Conodontophores are structures that contain conodonts, while conodont-bearing formations are rock layers that contain well-preserved conodonts. Conodont zones are specific intervals of geological time defined by the occurrence or absence of certain conodont species, which are used to correlate rock layers in different parts of the world.
