A bachelor party out to have a good time before their friend got married made an ancient fossil discovery by mistake. Most bachelor parties don’t go driving through Elephant Butte State Park in New Mexico, but Antonio Gradillas and friends did and what a discovery.

As they were driving they noticed a large tusk sticking out of the ground so they formed a digging party and they unearthed the giant remains of a prehistoric elephant skull. Scientists think it’s a Stegomastodon and the skull looks to 100% complete. It’s one of the most complete skulls ever found and dates back about 3 million years.

The skull weighs nearly 1,000 pounds because it is full of sand and took about six hours to recover. Experts will continue to clean it and study it over the next several months.
