1905 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 1905.

Name	Status	Authors		Age	Unit	Location	Notes	Images
Albertosaurus[3]	Valid taxon	Henry Fairfield Osborn		Late Cretaceous (Edmontonian)	Horseshoe Canyon Formation	Canada	An albertosaurine tyrannosaurid.	Tyrannosaurus
"Diceratops"[4]	Preoccupied.	Lull vide: Hatcher		Late Cretaceous (Lancian)	Lance Formation	United States	Has been considered a member of Triceratops, but recent work has indicated it deserved its own genus after all. In 2008 it was renamed Diceratus because Diceratops was preoccupied by a hymenopteran insect Foerster, 1868.
"Dynamosaurus"[3]	Junior synonym.	Henry Fairfield Osborn		Late Cretaceous (Lancian)	Lance Formation	United States	Same as Tyrannosaurus, this name was rejected because Tyrannosaurus was mentioned earlier in the paper.
Stegopelta[5]	Valid taxon	Williston		Middle Cretaceous (Cenomanian)	Frontier Formation	United States	A nodosaurid.
Tyrannosaurus[3]	Valid taxon	Henry Fairfield Osborn		Late Cretaceous (Lancian)	Lance Formation Hell Creek Formation Scollard Formation North Horn Formation McRae Formation Frenchman Formation Denver Formation Laramie Formation	United States  Canada	Tyrannosaurus is the largest recognized tyrannosauroid and one of the most famous dinosaurs.
