The horse had arthritis when it died. It’s potential, too, that it had bone most cancers in a single ankle.

That may occur to any horse as soon as it will get to be a sure age. This one is sort of 16,000 years previous.

Paleontologists final week recognized the skeleton of a horse from the ice age in Lehi, Utah — a very uncommon discovery on condition that a lot of the western a part of the state was underwater till about 14,000 years in the past. Buried for 1000’s of years beneath seven ft of sandy clay, the stays have been found solely when the Hill household started transferring dust round their yard to construct a retaining wall and plant some grass.

Laura Hill mentioned she and her husband, Bridger, uncovered the skeleton final September, however didn’t assume a lot of it at first. They puzzled if it was a cow; Lehi is about 15 miles from Provo and was as soon as largely farmland that hugged the perimeters of close by Utah Lake. She consulted a neighbor, a geology professor at Brigham Younger College, who examined the bones, and guessed they have been from a horse from the Pleistocene Period.

“I used to be shocked,” Ms. Hill mentioned. “That is one thing we didn’t count on.”

Rick Hunter, a paleontologist on the Museum of Historical Life, a brief drive from the Hill residence, mentioned Ms. Hill approached him final month to examine the household’s discovery.

“She got here in and mentioned, “I discovered a skeleton within the yard and I don’t know what to do,’” Mr. Hunter recalled. “I replied, ‘I do.’” Final week he and a workforce from the museum’s lab, the place they examine dinosaur fossils, went to her residence.

The skeleton was lacking its head, however was in any other case intact. Mr. Hunter estimated the horse to be the scale of a Shetland pony; it was discovered mendacity on its left facet, with all 4 legs tucked close to its torso. Elements of the skeleton have been broken from publicity to climate. Curious onlookers had picked on the ribs and different bones.

Mr. Hunter didn’t know the way the animal died, however he has a principle. Utah was coated over the last ice age by Lake Bonneville, a prehistoric lake. (The Nice Salt Lake because it at the moment exists is a remnant of Lake Bonneville.)

Maybe the horse was attempting to flee from a predator and bumped into the lake, Mr. Hunter surmised. “Horses can swim,” he mentioned. “Perhaps it obtained trapped on the market, drowned and sank to the underside.

Mr. Hunter mentioned he and his workforce visited the positioning on the Hill residence for 2 days final week to excavate the stays. The bones have been uncovered in a sandbank seven ft beneath the floor. “This isn’t unusual,” the paleontologist mentioned. Nonetheless, there was the query of what occurred to the top.

He broadened the search to 50 ft past the unique website. Within the expanded space the group discovered bone fragments, molars and small items of the cranium. Thriller solved: The cranium had been shattered and moved when the landscaper cleared the land.

The skeleton was taken again to the museum final week, the place it is going to be cataloged, preserved and repaired. Not like with dinosaurs, the horse’s bones have been dehydrated and never but fossils. Fossilized minerals in bone flip to stone, however the horse was not sufficiently old for that to have occurred. That posed an issue for Mr. Hunter’s workforce. “In the event that they dry too shortly, they may crack,” he mentioned. “It’s a must to treatment them slowly.”

Mr. Hunter additionally hopes to pin down the horse’s age with higher precision. The present estimate of 14,000 to 16,000 years is the workforce’s finest guess till it may be studied additional. As soon as the skeleton is reassembled, Mr. Hunter mentioned, he would really like it to turn into a everlasting exhibit on the Museum of Historical Life. Mr. Ross of the American Museum of Pure Historical past concurred.

“It’s necessary that it leads to an establishment someplace,” he mentioned.

Ms. Hill mentioned she and her husband weren’t certain what they have been going to do but. She mentioned neighbors had flocked to the yard to see the oddity earlier than it was eliminated, and relations have been advising the couple to have the skeleton appraised. (They’re hoping to get a tax deduction in the event that they donate it.) “It might be good to have it right here on the museum,” Ms. Hill mentioned. “Mr. Hunter does need us to donate it.”

When Mr. Hunter visited final week he introduced a volunteer who talked to the neighborhood kids about Lake Bonneville, historic animals and, after all, the horse within the yard. Mr. Hunter mentioned he would identify it “Hill Horse” in honor of the household that discovered it.

Ms. Hill was happy. “Now all these little children need to be paleontologists,” she mentioned with fun.
