In one corner of the mazelike, climate-controlled room at the heart of UC Berkeley, a triceratops horn rests on a shelf a few inches above the floor. The massive skull of a baleen whale that lived some 15 million years ago is fixed to a wooden plank bolted to a nearby wall. There are drawers upon drawers stuffed with skeletons and labeled with locations that dot the globe.
Anyone who enters the Valley Life Sciences Building has likely seen the replica Tyrannosaurus rex on the ground floor, in the circular stairwell. It’s but one of dozens of pieces on display just outside the museum doors, like the skeleton of Stenopterygius, a Jurassic marine reptile.
But it’s farther inside the museum where tens of millions of years of history unfold among the movable shelves of the University of California Museum of Paleontology. Normally off-limits to all but select researchers, the space is home to hundreds of thousands of pieces that range from massive dinosaur bones to minuscule invertebrate fossils. The state’s designated museum for California fossils, it is home to massive aquatic predators discovered in Shasta County and scores of specimens plucked from the La Brea tar pits in Los Angeles.
