Paleontology or palaeontology 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 1886.

Pallimnarchus pollens^[3]	Nomen dubium	De Vis	Pliocene	Darling Downs	Australia	Pallimnarchus was informally named, but the name acquired widespread use. The syntype material consisted of multiple individuals of different crocodilian species and a later erected lectotype was lost. It was eventually declared a nomen dubium, with much of the material transferred into the genus Paludirex.^[4]	The lectotype of Pallimnarchus, B shows the only parts still known.
