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 2016.

A study on the respiratory system and paleobiology of caseids is published by Lambertz et al. (2016), who argue that at least some caseids might have been predominantly aquatic and that a homologue of the mammalian diaphragm might have been present in caseids.
A redescription of the sphenacodontian taxa Palaeohatteria and Pantelosaurus is published by Spindler (2016), who assigns both these taxa to the clade Palaeohatteriidae, but considers it likely that they represent distinct valid taxa.
A study on the paleoneurology of non-mammaliaform therapsids is published by Benoit, Manger & Rubidge (2016), who argue that whiskers, body hair coverage and mammary glands might have been present in some non-mammaliaform therapsids.
A study on the occurrence and size of the parietal foramen (an opening in which the pineal eye is located) in non-mammaliaform therapsids (especially non-mammaliaform eutheriodonts) known from the Karoo Supergroup of South Africa is published by Benoit et al. (2016).
A study of life histories and growth patterns as indicated by bone tissue microstructure and body size in members of three synapsid groups that survived Permian–Triassic extinction event (dicynodonts, therocephalians and cynodonts) and one that didn't (gorgonopsians) is published by Botha-Brink et al. (2016).
A revision of the systematics of the gorgonopsian subfamily Rubidgeinae is published by Kammerer (2016).

Hair-like structures found in a coprolite recovered from the Late Permian Vyazniki site (Russia), which might represent the oldest evidence of hair in the stem group of mammals, are described by Bajdek et al. (2016).

=Traces of a wriggling, mucus-secreting animal are described from the Ediacaran Doushantuo Formation (China) by Wang et al. (2016), who name a new ichnotaxon Linbotulitaenia globulus.
New fossils of Ernietta plateauensis are described from the Ediacaran site in southern Namibia by Elliott et al. (2016).
Embryo-like fossils are described from the Ediacaran Doushantuo Formation (China) by Yin et al. (2016), who argue that at least some of these fossils represent crown-animal embryos.

=Probable stromatolites are described from the 3,700-Myr-old rocks from the Isua supracrustal belt (Greenland) by Nutman et al. (2016); however, Allwood et al. (2018) subsequently argue that these putative stromatolites as more likely to be structures of non-biological origin.

Organic-walled microfossils (at least some of which are eukaryote fossils) with holes in the walls similar to those formed by predatory protists in the walls of their prey to consume the contents inside are described from the 780–740 million-year-old Chuar Group (Grand Canyon, Arizona, USA) by Porter (2016).
