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.[1] This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (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 1905.

Name Status Authors Age Unit Location Notes Images

Albertosaurus[3]

Valid taxon

Late Cretaceous (Edmontonian)

Horseshoe Canyon Formation

 Canada

An albertosaurine tyrannosaurid.

Albisaurus[4]

Nomen dubium.

  • Fritsch

Late Cretaceous (Turonian)

Unnamed chalk deposits

 Czech Republic

May have been a misidentified marine reptile.

"Diceratops"[5]

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.

Late Cretaceous (Lancian)

Lance Formation

 United States

Same as Tyrannosaurus, this name was rejected because Tyrannosaurus was mentioned earlier in the paper.

"Procerosaurus"

Preoccupied.

  • Fritsch

Late Cretaceous (Turonian)

Unnamed chalk deposits

 Czech Republic

Preoccupied by a name erected by Friedrich von Huene in 1902, this "Procerosaurus" would be later be renamed Ponerosteus.

"Stegopelta"[6]

Valid taxon

  • Williston

Middle Cretaceous (Cenomanian)

Frontier Formation

 United States

A nodosaurid.

Tyrannosaurus[3]

Tyrannosaurus is the largest recognized tyrannosauroid and one of the most famous dinosaurs.
