A bunch of men were having a bachelor party at a state park popular for its camping, hiking, fishing and boating when they saw a skull of a mastodon with complete tusks sticking out of the sand along a lakeshore. They contacted a University of New Mexico professor who connected them with the head paleontologist at the New Mexico Museum of Natural History and Science. He was amazed because the skull was so complete, would be easy to excavate from sand within a day's time, and was found in a very popular area. The mean of the bachelor party also didn't disturb the skull.
