Paleontology, palaeontology or palæontology (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. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised faeces (coprolites), palynomorphs and chemical residues. Because mankind has 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 in the year 2000.

Name	Status	Authors	Discovery year	Age	Unit	Location	Notes	Images
Bambiraptor	Valid	Burnham Derstler et al.			Two Medicine Formation	USA	A very bird-like two foot long dromaeosaurid. May be a juvenile Saurornitholestes.	Bambiraptor Charonosaurus Fukuiraptor Graciliceratops Microraptor Nanyangosaurus Nomingia Pyroraptor with a human to show scale. Sauroposeidon with a human to show scale.
Byronosaurus	Valid	Mark Norell Makovicky Clark			Djadochta Formation	Mongolia	A five foot long troodontid. Mysteriously, skulls of extremely small juveniles have been recovered from an oviraptorosaur nest. This may be evidence of brood parasitism or predator-prey relationships between the two species.

Chuanjiesaurus	Valid	Fang Pang et al.			Chuanjie Formation	China	A mamenchisaurid.
Fukuiraptor	Valid	Azuma Phillip Currie			Kitadani Formation	Japan	A neovenatorid known only from juvenile specimens.
"Ginnareemimus"	Nomen nudum	Kaneko			Sao Khua Formation	Thailand	Formally named Kinnareemimus in 2009 in paleontology.
Glyptodontopelta	Valid	Ford			Ojo Alamo Sandstone	USA	Named after the armored mammal Glyptodon.
Graciliceratops	Valid	Paul Sereno			Sheeregeen Gashoon Formation	Mongolia	Primitive ceratopsian. Only a partial skeleton has been found.
Huabeisaurus	Valid	Pang Cheng Z.			Huiquanpu Formation	China	Opisthocoelicaudia-like titanosaurid.
“Iguanoides”	Nomen nudum; synonym of Iguanodon	Conybeare vide: Cadbury					Junior synonym of Iguanodon.
Ilokelesia	Valid	Rodolfo Coria Salgado			Rio Limay Formation	Argentina	A primitive abelisaur who name is derived from "flesh lizard" in Mapuche.
Isanosaurus	Valid	Buffetaut Suteethorn et al.			Nam Phong Formation	Thailand	A small, 6.5 metres (21 ft) long sauropod.
Jeholosaurus	Valid	Xu Xing Wang X. You			Yixian Formation	China	A 71.1 centimetres (28.0 in) long hypsilophodont.

Nomingia	Valid	Rinchen Barsbold Halszka Osmólska et al.			Beds of Bugeen Tsav	Mongolia	The first non-avian dinosaur known to have a pygostyle at the end of its tail. In life this structure probably supported a fan of feathers.

"Ponerosteus"	Nomen dubium; possibly non-dinosaurian	George Olshevsky,					A dubious taxon whose name means "useless bone" to reflect the low quality of the material, which had fueled taxonomic confusion.
Pyroraptor	Valid	Allain Philippe Taquet			Grès à Reptiles	France	A dromaeosaurid known from a single specimen.
Rocasaurus	Valid	Salgado Azpilicueta			Allen Formation	Argentina	A small, 8 meter long titanosaur.
