• Matt Perkins and his husband were in the midst of having a pool installed in the backyard of their new home in Las Vegas when police and crime scene investigators showed up on April 26.
The pool builders had unearthed some bones buried about 5 feet below the surface, the Associated Press reported.
The bones turned out not to be human; they are those of a horse or other large mammal.
More important, they are not recent: Nevada Science Center Research Director Joshua Bonde said they're dating to Earth's most recent Ice Age.
The area was once a watering spot for wildlife in the Mohave Desert.
Bonde said U.S. laws give ownership of fossils to property owners; Perkins is deciding how best to preserve the antiquities.
