Asian land mammal age, the Glossary

Index Asian land mammal age

The Asian land mammal ages, acronym ALMA, establish a geologic timescale for prehistoric Asian fauna beginning 58.7 Mya during the Paleogene and continuing through to the Miocene (Aquitanian) (23.03 Ma).[1]

Aquitanian (stage)

The Aquitanian is, in the International Commission on Stratigraphy's (ICS) geologic timescale, the oldest age or lowest stage in the Miocene.

See Asian land mammal age and Aquitanian (stage)

Arshantan

The Arshantan age is a period of geologic time (48.6–37.2 Ma) within the Early Eocene epoch of the Paleogene used more specifically with Asian Land Mammal Ages.

See Asian land mammal age and Arshantan

Biochronology

In paleontology, biochronology is the correlation in time of biological events using fossils.

See Asian land mammal age and Biochronology

Bumbanian

The Bumbanian is an Asian Land Mammal Age (ALMA), a large biozone which corresponds to ages between 55.8–46.8 Ma for finds of fossil mammals in Asia.

See Asian land mammal age and Bumbanian

Ergilian

The Ergilian age is a period of geologic time (37.2–33.9 Ma) within the Late Eocene epoch of the Paleogene used more specifically with Asian Land Mammal Ages.

See Asian land mammal age and Ergilian

European land mammal age

The European Land Mammal Mega Zones (abbreviation: ELMMZ, more commonly known as European land mammal ages or ELMA) are zones in rock layers that have a specific assemblage of fossils (biozones) based on occurrences of fossil assemblages of European land mammals. Asian land mammal age and European land mammal age are biochronology and Regional geologic time scales.

See Asian land mammal age and European land mammal age

Fauna

Fauna (faunae or faunas) is all of the animal life present in a particular region or time.

See Asian land mammal age and Fauna

Fossil

A fossil (from Classical Latin) is any preserved remains, impression, or trace of any once-living thing from a past geological age.

See Asian land mammal age and Fossil

Gashatan

The Gashatan is an Asian Land Mammal Age, a large biozone which corresponds to ages between 58.7–55.8 Ma for finds of fossil mammals in Asia.

See Asian land mammal age and Gashatan

Geologic time scale

The geologic time scale or geological time scale (GTS) is a representation of time based on the rock record of Earth.

Houldjinian

The Houldjinian age is a period of geologic time (37.2–33.9 Ma) within the Late Eocene epoch of the Paleogene used more specifically with Asian Land Mammal Ages.

See Asian land mammal age and Houldjinian

Hsandagolian

The Hsandagolian age is a period of geologic time (33.9 – 23.03 Ma) within the Oligocene epoch of the Paleogene used more specifically with Asian Land Mammal Ages.

See Asian land mammal age and Hsandagolian

Irdinmanhan

The Irdinmanhan age is a period of geologic time (48.6–37.2 Ma) within the Middle Eocene epoch of the Paleogene used more specifically with Asian Land Mammal Ages.

See Asian land mammal age and Irdinmanhan

Kekeamuan

The Kekeamuan age is a period of geologic time (33.9–28.4 Ma) within the Early Oligocene Epoch of the Paleogene Period.

See Asian land mammal age and Kekeamuan

Million years ago

Million years ago, abbreviated as Mya, Myr (megayear) or Ma (megaannum), is a unit of time equal to (i.e. years), or approximately 31.6 teraseconds.

See Asian land mammal age and Million years ago

Miocene

The Miocene is the first geological epoch of the Neogene Period and extends from about (Ma).

See Asian land mammal age and Miocene

North American land mammal age

The North American land mammal ages (NALMA) establishes a geologic timescale for North American fauna beginning during the Late Cretaceous and continuing through to the present. Asian land mammal age and North American land mammal age are Regional geologic time scales.

See Asian land mammal age and North American land mammal age

Paleogene

The Paleogene Period (also spelled Palaeogene or Palæogene) is a geologic period and system that spans 43 million years from the end of the Cretaceous Period Ma (million years ago) to the beginning of the Neogene Period Ma.

See Asian land mammal age and Paleogene

Prehistory

Prehistory, also called pre-literary history, is the period of human history between the first known use of stone tools by hominins million years ago and the beginning of recorded history with the invention of writing systems.

See Asian land mammal age and Prehistory

Quarry

A quarry is a type of open-pit mine in which dimension stone, rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground.

See Asian land mammal age and Quarry

Sharamurunian

The Sharamurunian age is a period of geologic time (48.6–37.2 Ma) within the Middle Eocene epoch of the Paleogene used more specifically with Asian Land Mammal Ages.

See Asian land mammal age and Sharamurunian

South American land mammal age

The South American land mammal ages (SALMA) establish a geologic timescale for prehistoric South American fauna beginning 64.5 Ma during the Paleocene and continuing through to the Late Pleistocene (0.011 Ma). Asian land mammal age and South American land mammal age are Regional geologic time scales.

See Asian land mammal age and South American land mammal age

Stratigraphy

Stratigraphy is a branch of geology concerned with the study of rock layers (strata) and layering (stratification).

See Asian land mammal age and Stratigraphy

Tabenbulakian

The Tabenbulakian age is a period of geologic time (28.4–23.03 Ma) within the Oligocene Epoch of the late Paleogene Period and Miocene Epoch of the early Neogene Period, used more specifically with Asian Land Mammal Ages.

See Asian land mammal age and Tabenbulakian

Taxon

In biology, a taxon (back-formation from taxonomy;: taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit.

See Asian land mammal age and Taxon

Ulangochuian

The Ulangochuian age is a period of geologic time (37.2–33.9 Ma) within the Late Eocene epoch of the Paleogene used more specifically with Asian Land Mammal Ages.
