The fossilized bones of an ancient bison were found at a highway construction site in San Diego’s North County. Experts at the San Diego Natural History Museum say the animal, which lived during the last Ice Age, is the first bison fossil found in Southern California.

The museum unveiled the fossil this week and visitors could watch staff clean away sediment deposits.
