When Laura Hill and her husband started a landscaping project, they didn’t think much of the skeleton that was uncovered. Initially, they assumed it was a cow. It was about the size of a Shetland pony and it was missing its head.

Luckily, before it was destroyed, she asked a neighbor about it, who happened to be a geology professor at Brigham Young University. He examined the bones and guessed they were a horse from

the Pleistocene Era — it was around this time — 12,000 – 16,000 years ago — that a global cooling event precipitated the extinction of many large mammals. North America was one of the geographic areas hit hardest, and this species of prehistoric horse was one of those that didn’t survive.
Although the bones of the horse had not fossilized yet (they weren’t old enough), the find is considered significant. The skeleton has been removed to the Museum where it will be catalogued, preserved and repaired.

The funniest part of the landscape test in Ca is they say “what do you do on a job if you find bones? The answer is call the undertaker. This is on the state test!
