Allosuarus, like Al here, lived 155 to 150 million years ago and averaged about 28 feet in length.
Look past Big Al’s daggerlike teeth and you’ll see that the 10-foot-tall allosaurus endured some Jurassic-size knocks in his day. His well-preserved remains reveal a mangled toe and some cracked ribs—injuries that date back more than 145 million years to the time when this carnivore stalked his meals in what is now northern Wyoming. Al is on display with one of his contemporaries—a 75-foot-long apatosaurus—at the University of Wyoming Geological Museum in Laramie. (307) 766-2646, www.uwyo.edu/geomuseum.
