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.
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
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
An early hadrosauroid iguanodont, about 17 - 20 feet (5 - 6 metres) in length. It had a narrow snout, an elongated lower jaw and double rows of flattened cheek teeth. It was a possible ancestor of the duck-billed dinosaurs.
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.
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.
