On November 23, the Bullock Museum in Austin will open its new exhibit, "Extreme Mammals: The Biggest, Smallest and Most Amazing Mammals of All Time." The exhibit features amazing creatures, including a 15-foot tall re-creation of an extinct mammal that was the size of three to four African elephants. Learn about the lives of mammals as small as a bumblebee, one with a tongue that weighed four tons, and a wide assortment of creatures with massive claws, fangs and odd snouts.

Family and children's activities from noon to 3 pm include: Mammal Trivia, Animal Olympics, Design-a-Mammal and Exploration Stations with touchable mammal specimens.
