Photo: The George C. Page Museum, part of the Natural History Museum of Los Angeles County, was built next to the tar pits in Hancock Park on Wilshire Boulevard. Construction began in 1975 and the museum opened to the public in 1977. It tells the story of the tar pits and presents specimens from them.
Photo: Specimens on display at the museum were alive during the Pleistocene Era (40,000 - 11,000 Years ago).  For further info:  http://www.tarpits.org/
Photo: Only one human has ever been found, a partial skeleton of the "La Brea Woman" dated to approximately 10,000 years ago, who was 17 to 25 years old at death, and found associated with remains of a domestic dog, and so was interpreted to have been ceremonially buried.
Photo: Smilodon, often called a saber-toothed cat or incorrectly a saber-toothed tiger, is an extinct genus of machairodonts. This saber-toothed cat was endemic to North and South America, living during the Pleistocene epoch (2.5 million to 10,000 years ago).
Photo: The nickname "saber-tooth" refers to the extreme length of their maxillary canines. Despite the colloquial name "saber-toothed tiger", Smilodon is not closely related to the tiger (or any other living cat). The name Smilodon comes from Greek for "carving knife" + "tooth".
Photo: On the grounds of the park are life-size models of prehistoric animals in or near the tar pits.
Photo: Harlan's ground sloth (Paramylodon) is an extinct genus of ground sloth. Paramylodon measured about 10 ft in height and weighted as much as 2400 lbs.

Photo: The short-faced bear or bulldog bear (Arctodus simus) is an extinct genus of bear endemic to North America during the Pleistocene ~3.0 million to 11,000 years ago.
Photo: The short-faced bear may have once been Earth's largest mammalian, terrestrial carnivore. The species is thought to have been larger than any living species of bear.
Photo: The short-faced bear was the most common of early North American bears, being most abundant in California.
Photo: The American mastodon (Mammut americanum) is an extinct North American proboscidean that lived from about 3.7 million years ago until about 10,000 BC. It was the last surviving member of the mastodon family.
Photo: The American mastodon resembled a woolly mammoth in appearance, with a thick coat of shaggy hair. A few skeletons have been found with the fur still attached; examination of the hair suggests that mastodons lacked the undercoat characteristic of mammoths. It was about 10 ft in height at the shoulder and reached a weight of about 6 tons.
Photo: The Columbian mammoth (Mammuthus columbi) is an extinct species of elephant of the Quaternary period that appeared in North America during the late Pleistocene.
Photo: Large Columbian mammoth males ranged from 12–13 ft high and weighed 8–10 tons) with spiralled tusks that could grow up to 14 ft long.
Photo: The remains of Columbian mammoths were discovered in the La Brea Tar Pits and the skeleton of one of them is on exhibit in that site's museum.
Photo: Its molars had low crowns and a small number of thick enamel ridges, adapted to a woodland diet of leaves and shrubs. This indicates it lived in a relatively warm climate which makes more probable that it lacked dense fur.

Photo: Western Horse (Equus Occidentalis) Horses evolved in North America about 50 million years ago and survived until about 11,000 years ago. The western horse was one of the last horse species native to North America. (All horses now in the Americas were imported from Eurasia after Columbus' discovery.)
Photo: Ancient Bison (Bison Antiquus) - Bison are the most common large herbivores from Rancho La Brea. Originating in Asia, they only entered North America about 200,000 years ago.  Bison Antiquus was the most common large herbivore of the North American continent for over ten thousand years, and is a direct ancestor of the living American bison.
Photo: The dire wolf (Canis dirus "fearsome dog") is an extinct carnivorous mammal of the genus Canis related to the smaller currently living gray wolf. It was most common in North America and South America from 1.80 million to 10,000 years ago.
Photo: The dire wolf averaged about 5 ft in length and weighed between 110 lb and 175 lb. The dire wolf  weighed 25% more than living gray wolves.[
Photo: The dire wolf had an overpowering bite that could hold and subdue its prey. Its bite force was 1.3 times that of the modern gray wolf. As inferred from its large body and carnivorous teeth, it often took on large prey. Travelling in packs made this possible for dire wolves.
