Construction in Oceanside Uncovers 45-Million-Year-Old Fossils of Mysterious Hoofed Mammal
Construction crews in Oceanside, California, unearthed the fossilized remains of a large, extinct hoofed mammal dating back 40 to 45 million years. The discovery, found 12 feet underground during a water infrastructure project, includes limb bones and ribs. Scientists believe the animal is either a 'thunder beast' or a 'swamp rhino,' but identification remains uncertain without a skull.
