WThe Astaracian age is a period of geologic time, 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.
WHanna Czeczott was a Polish botanist, and paleobiologist. She was award the Order of the Banner of Work.
WThe Late Cenozoic Ice Age, or Antarctic Glaciation began 33.9 million years ago at the Eocene-Oligocene Boundary and is ongoing. It is Earth's current ice age or icehouse period. Its beginning is marked by the formation of the Antarctic ice sheets. The Late Cenozoic Ice Age gets its name due to the fact that it covers roughly the last half of Cenozoic era so far.
WMessapicetus is an extinct genus of beaked whale from the Late Miocene. It currently holds two species, M. longirostris from the Tortonian of Italy and M. gregarius from the Pisco Formation of Peru. However, a third unnamed species is represented in the St. Marys Formation of Maryland known from fragmentary material. M. gregarius is sexually dimorphic, males having tusks which are hypothesized to have been used in intraspecific combat for mates as in extant (living) beaked whales.
WNacholapithecus is a Middle Miocene genus of hominoid found in the Nachola formation in northern Kenya. It is a key genus in early hominid evolution. Similar in body plan to Proconsul, it had a long vertebral column with six lumbar vertebrae, no tail, a narrow torso, large upper limbs with mobile shoulder joints, and long feet.
WThe Orleanian age is a period of geologic time, within the Miocene and used more specifically with European Land Mammal Ages. It precedes the Astaracian age and follows the Agenian age.Agenian-Early Orleanian migration 23.8 to 18 mya
WPuente del Inca, is a natural arch that forms a bridge over the Las Cuevas River, a tributary of the Mendoza River. It is located in Mendoza Province, Argentina, near Las Cuevas. The nearby hot springs are also named Puente del Inca.
WThe 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 so-called Vallesian Crisis resulted in the extinction of several mammalian taxa characteristic of the Middle Miocene.
