Astaracian
Encyclopedia
The Astaracian age age is a period of geologic time (16.0—11.6 Ma), equivalent with the Middle Miocene
and used more specifically with European Land Mammal Ages
. It precedes the Vallesian
age and follows the Orleanian
age. The Astaracian overlaps the Langhian
and Serravallian
ages.
Middle Miocene
The Middle Miocene is a sub-epoch of the Miocene Epoch made up of two stages: the Langhian and Serravallian stages. The Middle Miocene is preceded by the Early Miocene....

European Land Mammal Ages
The European Land Mammal Mega Zones are zones in rock layers that have a specific assemblage of fossils based on occurrences of fossil assemblages of European land mammals. These biozones cover most of the Neogene and Paleogene systems The European Land Mammal Mega Zones (abbreviation: ELMMZ,...

Vallesian
The Vallesian age is a period of geologic time within the Miocene used more specifically with European Land Mammal Ages. It precedes the Turolian age and follows the Astaracian age. The Turolian overlaps the Tortonian and Messinian ages....

age. The Astaracian overlaps the Langhian
Langhian
The Langhian is, in the ICS geologic timescale, an age or stage in the middle Miocene epoch/series. It spans the time between 15.97 ± 0.05 Ma and 13.65 ± 0.05 Ma . The Langhian was a continuing warming period defined by Lorenzo Pareto in 1864, it was originally established in the Langhe area north...

Serravallian
The Serravallian is in the geologic timescale an age or a stage in the middle Miocene epoch/series, that spans the time between 13.65 ± 0.05 Ma and 11.608 ± 0.005 Ma...
