The Albian is both an age of the geologic timescale and a stage in the stratigraphic column

epoch
/series
. Its approximate time range is 112.0 ± 1.0 Ma to 99.6 ± 0.9 Ma (million years ago). The Albian is preceded by the Aptian
and followed by the Cenomanian

.
The base of the Albian is defined as the place in the stratigraphic column where the coccolithophore
species Praediscosphaera columnata first appears. A reference profile for the base of the Albian stage (its GSSP) had in 2009 not yet been established.
The top of the Albian stage (the base of the Cenomanian stage and Upper Cretaceous series) is defined as the place where the foram species Rotalipora globotruncanoides first appears in the stratigraphic column.
The Albian is sometimes subdivided in Early/Lower, Middle and Late/Upper subages or substages. In western Europe, especially in the UK, a subdivision in two substages (Vraconian and Gaultian) is more often used.

Fukuiraptor Fukuiraptor was a medium-sized carnivore of the Early Cretaceous that lived in what is now Japan. Scientists first thought it was a member of the Dromaeosauridae, but after studying the fossils they now believe it was related to Allosaurus in the family Neovenatoridae. The type specimen is the... |

Originating in Lower Albian Strata
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 Albian stage, or even into later geological stages. This list should not be thought of in terms of the lifespan of the genera included.
- AiolocerasAiolocerasAioloceras is an ammonite, order Ammonitida, from near the end of the Early Cretaceous. The shell is compressed with the outer whorl covering much of the previous. Sides are slightly convex, converge toward a narrowly ached venter. Inner whorls have sharp falcoid ribs, outer are smooth. Umbilical...
