Cenozoic Hall: The Hall of Ice Age Animals
Cenozoic Hall reflects the most recent 65 million years of the history of life on Earth, known as the Cenozoic Era, or the Age of Mammals. Although mammals had evolved during the early part of the Mesozoic Era (the Age of Dinosaurs), they thrived during the Cenozoic, when the absence of dinosaurs made it possible for a great diversity of species to emerge.
The last two million years of earth history are the Pleistocene Epoch, or the Ice Age. At least four times during this epoch, ice sheets advanced and retreated over much of the northern hemisphere. The fluctuating climatic conditions strongly affected plant and animal evolution and distribution.
The fantastic creatures that have evolved during this era are featured in the Hall of Fossil Mammals. Displayed in the hall are fossil representatives of Cenozoic plants, fish, and mammals. The exhibitions are arranged chronologically according to their appearance in the fossil record. Actual skeletons and lifelike models illustrate the various life forms that flourished two million years ago. Other exhibitions demonstrate anatomical changes, such as the evolution of two families that were originally North American natives: the camel and the horse. Visitors can see the evolution of the horse from a small cat-sized animal to today's recognizable animal. The hall also discovers early ancestors of the llama, rhino, and dog.
Pleistocene Epoch Hall has several well-known Ice Age species on exhibit such as the animals from California's famous Rancho La Brea tar pits: the Colombian mammoth with stone spear points, so-called Clovis Points, that were made by the Paleoindians and the American mastodon, possibly the largest one ever discovered. Also on exhibit are the Irish elk and the moa, a large, flightless bird from New Zealand.
