Earth during Pleistocene, years ago

Last Glacial Maximum

The earth was a pretty cold place years ago at the Last Glacial Maximum. Some geologist think we may be on the verge of plummeting into another one, myself included.

Tethys Ocean, in the area today covered by India, Pakistan, and Indonesia.  Its western arm became the Mediterranean.

Earth in the Miocene - apart from higher sea levels, warmer temperatures, and slightly different critters, not too different from today's Earth.

The bull's eye marks the location of the Chicxulub impact site. The impact of a 10 mile wide meteor caused global climate changes that killed the dinosaurs and many other forms of life. By the Late Cretaceous the oceans had widened, and India approached the southern margin of Asia. The Chicxulub crater is buried underneath the Yucatán Peninsula in Mexico, and occurred 65 million years ago at the Createceous-Tertiary (K-T) boundary.
