Conodonts are extinct agnathan chordates resembling eels, classified in the class Conodonta. For many years, they were known only from tooth-like microfossils found in isolation and now called conodont elements. Knowledge about soft tissues remains limited. The animals are also called Conodontophora to avoid ambiguity.
Promissum is an extinct genus of conodonts, primitive chordates, that lived during the Upper Ordovician period.
Archaeognathus is a fossilized jaw apparatus from the Ordovician that has been compared to the conodonts and vertebrates, yet remains unclassified.
Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 2013.
The St. Clair Limestone is a geologic formation in Arkansas, Indiana, Missouri, and Oklahoma. It preserves fossils dating back to the Silurian period. This high density, high magnisium dolomitic limestone was originally classified as a marble in Oklahoma due to the fact that it would hold a high polish, hence Marble City.
This timeline of Permian research is a chronological listing of events in the history of geology and paleontology focused on the study of earth during the span of time lasting from 298.9–252.17 million years ago and the legacies of this period in the rock and fossil records.
