It features two epochs: the Miocene and the Pliocene. citation The Miocene spans from 23 to 5 million years ago and is a period in which grass spreads further across, effectively dominating a large portion of the world, diminishing forests in the process.

Importantly, this fossil is from the time period known as the late Miocene when the Tibetan Plateau was continuing to rise rapidly in altitude and changing the climate of central Asia with an increase in aridity, along with a strong monsoon season.

According to DNA studies, the ancestor of the hammerheads probably lived in the Miocene epoch about 20 million years ago.

A large question remains as to why there was a progressive decline in hypercarnivorous carnivoramorphans during the late Oligocene/early Miocene.

Although there no records from the Miocene in the Atlantic, a re-examination of the North Carolina material indicated that the diversity of puffins in the early Pliocene was as great in the Atlantic as it is in the Pacific today.

But a significant share of the decline of perissodactyls was due to climate changes during the Miocene towards a cooler and dryer climate, which was accompanied by the spread of open landscapes.

Camel-like animals have been traced from the thoroughly differentiated, modern species back through early Miocene forms.

During the Middle Miocene this zone was affected by intensive calc-alkaline Pácskay, Z., Lexa, J., Szákacs, A., 2006, Geochronology of Neogene magmatism in the Carpathian arc and intra-Carpathian area.
