There is an informative website dealing with the famous La Brea Tar Pits, at http://www.tarpits.org/blog
I highly recommend checking it out. Their latest news shows many excellent pictures of activities going on at La Brea. Just go the link given above and start scrolling down. The picture that involves the "drifting" mammoth replica is particularly interesting.
Also, click on the "You Tube" link at the bottom right side of the main page. Then click on the video featuring Will Ferrell at the Page Museum. He was upstaged somewhat by a life-size, three-dimensional, moving replica of Smilodon, with fur and camouflage markings. It really makes it clear how the back of Smilodon was sloped (i.e., its front legs were longer than its rear legs).
In sum, checking out this website will be a valuable use of your time. Enjoy.
