Albian is a stage of the Cretaceous period.

Albian is a term proposed in 1842 by A. d'Orbigny for that stage of the Cretaceous system which comes above (later) the Aptian and below (before) the Cenomanian (Pal. France. Cret. ii.). Approximate time range is 113 to 100.5 Ma (million years ago).

The following representatives of the Albian stage are worthy of notice: the gaize and phosphatic beds of Argonne and Bray in France; the Flammenmergel of North Germany; the lignites of Iltrillas in Spain; the Upper Sandstones of Nubia, and the Fredericksburg beds of North America.

Sauropelta

Cedar Mountain Formation, Utah, USA
Aptian to ?Albian Ulansuhai Formation, Inner Mongolia, China
Aptian to Albian Cloverly Formation, Wyoming, Montana, Utah, USA A medium-sized nodosaurid, measuring about 5 meters (16.5 ft) long, Sauropelta had a distinctively long tail which made up about half of its body length. Its neck and back were protected by an extensive bony body armor including characteristically large spines
Mongolia
Dakota Formation, Kansas, USA A nodosaurid estimated to have been approximately four meters in length (13 ft). Besides the usual rounded and polygonal osteoderms, Silvisaurus may have also sported bony spines on its shoulders and tail
Late Albian to early Cenomanian Frontier Formation, Wyoming, USA A poorly known genus of nodosaurid
Paw Paw Formation, Texas, USA Poorly known, probably a nodosaurid

Originating in Lower Albian StrataEdit

The following is a list of Ammonite genera whose fossils are geochronologically found first in lower Albian strata. These genera may survive into later portions of the Ablian stage, or even into later geological stages. This list should not be thought of in terms of the lifespan of the genera included.

Originating in Middle Albian StrataEdit

The following is a list of Ammonite genera whose fossils are geochronologically found first in middle Albian strata. These genera may survive into later portions of the Ablian stage, or even into later geological stages. This list should not be thought of in terms of the lifespan of the genera included.

Originating in Upper Albian StrataEdit
