I just loved the whole idea of mammoths and saber-tooth tigers (not really tigers), when I was a kid.

The Mammoth Saga

This virtual exhibition of mammoths and other animals, and plants of the ice ages is based on an exhibition held at the Swedish Museum of Natural History, Stockholm, from May 11 to September 18, 1994. The material from the Russian tundra exhibited was made available by the Zoological Institute, St. Petersburg, Russia and the Zoological Museum, Kiev, Ukraine. Other items shown were from the collections of the Swedish Museum of Natural History.

I had the opportunity/misfortune to live in LA during the mid-eighties. One of the coolest things I saw (and there were some really cool things) was the La Brea Tar Pits. I was fascinated with them as a kid and it was a treat to see the amazing museum built around the amazing things that fell into that tar pit.

LaBrea Tar Pits

The Page Museum is located at the Rancho La Brea Tar Pits in the heart of Los Angeles. Rancho La Brea is one of the world’s most famous fossil localities, recognized for having the largest and most diverse assemblage of extinct Ice Age plants and animals in the world. Visitors can learn about Los Angeles as it was between 10,000 and 40,000 years ago, during the last Ice Age, when animals such as saber-toothed cats and mammoths roamed the Los Angeles Basin. Through windows at the Page Museum Laboratory, visitors can watch bones being cleaned and repaired. Outside the Museum, in Hancock Park, life-size replicas of several extinct mammals are featured.
