1986 in paleontology

Wikimedia Commons has media related to 1986 in paleontology.

Paleontology or palaeontology (from Greek: paleo, "ancient"; ontos, "being"; and logos, "knowledge") is the study of prehistoric life forms on Earth through the examination of plant and animal fossils.^[1] 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 1986.

• Fossil jaw fragments containing multicusped teeth were found in Dockum Group rocks in western Texas.^[19] One fragment, apparently from a lower jaw, contained two teeth, each with five cusps.^[19] Another fragment, from an upper jaw, also contained several multi-cusped teeth.^[19] These finds are very similar to the pterosaur genus Eudimorphodon and may be attributable to this genus, although without better fossil remains it is impossible to be sure.^[19]
