Los Angeles Museum of Natural History showing displays of prehistoric skeletons, a mastodon and giant ground sloth, ca.1920

Interiors of the Los Angeles Museum of Natural History showing displays of prehistoric skeletons, a mastodon and a giant ground sloth ("from Rancho La Brea"), ca.1920. The two prehistoric skeletons, displayed on platforms, are made to look as if they are in motion. Tables nearby offer a view of prehistoric artifacts. Glass tops protect the artifacts. Throughout the room are a variety of bird figures (birds models?). At the top of the left wall are two sets of horns with labels describing them.; "American mastodons (Mammut americanum) stood about seven feet tall at the shoulder. They ate a variety of soft vegetation such as leaves and pine needles. Although they looked superficially similar, mastodons were only distantly related to mammoths and elephants." -- unknown author.
