Paleontology or palaeontology is the study of prehistoriclife 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 1821.
Conybeare named the genus in Plesiosaurus 1821 without designating a type species. The genus was named on the basis of a complete skeleton discovered by Mary Anning.
