The Tertiary Period  By: GMW555 Landforms/Fossils You have probably seen fossils before, but never really thought how long ago these were from. In this wiki we’re going to be talking about fossils that are from around 65 million years ago. There was an abundance of them since the La Brea tar pit in California captured tons of unexpected creatures who were fooled by the coating of water over the sticky substance underneath. Pray of an animal will walk in and get stuck it would then attract predators and they would also get stuck and it would preserve their bones perfectly. Not all of these fossils were found in the La Brea tar pit, some were found across the US and in Canada. The Indricotherium was the largest land mammal ever, and was found around in the eastern part of the US. Another example of a animal that lived back then was a Multituberculates. They where little rodent like mammals and are the only mammals that have no living ancestors today. About 20 mya the rodents of today, their competitors, nocked them out. Desmostylia is the last example that I have and it is a group of extinct marine mammals. They have been found in parts of Japan, Mexico and eastern US as far down as D.C. Besides from animals, the abiotic was have an evolution of its own. Land bridges where created, like Central America and the connection between Alaska and Russia, (this soon broke). The wher e plate tectonics crashing in to each other and forming spectacular mountains and raised areas. The biggest land form in this time was India smashing into Asia creating the Tibetan Plateau but more famously the Himalayan mountain rage. With all the new land and landforms it opened it up to anybody who decide to adapt and live there.
