Prehistoric Tank Tops

Kelenken guillermoi is a species of giant flightless predatory birds of the extinct family Phorusrhacidae, or "terror birds". Phorusrhacids, colloquially known as terror birds, are an extinct clade of large carnivorous flightless birds that were the largest species of apex predators in South America during the Cenozoic era; their temporal range covers from 62 to 1.8 million years (Ma) ago.

In the 1920s Captain Marshall Field funded two expeditions to South America which were undertaken by the Field Museum of Natural History in Chicago, Illinois; these expeditions were launched under the hopes of finding fossils of mammals and other animals from the Cenozoic Era. In 1926, during the second expedition, a team was searching the Ituzaingo Formation in northern Argentina when they came across the remains of three animals thought to be never before discovered species of ancient marsupial. It was roughly 4.9 feet in length and weighed around 330 pounds and it lived during the Late Miocene to Pliocene, roughly 9 to 3 million years ago.

A land dwelling prehistoric relative of modern day crocodiles described scientifically in 1959, head to tail it measured some 23 feet in length and weighed over 1,000 pounds. It roamed what would eventually become known by humans as North Western Argentina, and it shared its environment with a wide variety of other creatures, such as early dinosaurs like Herrerasaurus and Eoraptor, as well as massive dicynodonts like Ischigualastia, Pound for pound it appears to have been the largest predator in the region it inhabited, but this weight and its likely cold-blooded metabolism likely slowed it down. Despite this it was more than fast enough to catch up with prey of that era.

Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins c. 3.3 million years ago and the beginning of recorded history with the invention of writing systems

Estemmenosuchus mirabilis was a genus of therapsid that lived during the Middle Permian (267 million years ago). Found in what is now the Perm region of Russia in the 1960s, both of the currently recognized species: E. uralensis and E. mirabilis are most recognizable from their distinctive knobby, antler-like facial structures; these structures are in face where they get their name which means "crowned crocodile."
