Ice Age fossils found in Central Texas cave

Ice Age fossils found in Central Texas

A discovery in Central Texas is difficult what scientists know in regards to the area’s pre-historic previous. Fossils uncovered deep inside a Comal County cave are actually giving us a greater concept of what animals roamed round right here throughout the Ice Age.

COMAL COUNTY, Texas – A discovery deep underground in Central Texas is difficult what scientists thought they knew in regards to the area’s historical previous.

Inside a collapse Comal County, researchers have uncovered lots of of Ice Age fossils—some from animals by no means earlier than believed to have lived within the space.

What they’re saying:

“We thought we knew so much,” stated paleontologist John Moretti. “These fossils really kind of start to shake that idea.”

The backstory:

Moretti, an Ice Age paleontologist and analysis affiliate on the University of Texas, is a part of the duo behind the invention that’s now drawing consideration within the scientific group. Beginning in March of 2023, Moretti started travelling with caver, John Young, to Bender’s Cave. Equipped with snorkeling gear and wetsuits, the 2 repelled greater than thirty toes to a stream that runs by the cave system. Beneath the water’s floor, they found one thing exceptional.

“Under the water, the bed of this stream channel is just strewn with fossil Ice Age animal bones,” Moretti stated. “They’re everywhere.”

Over the course of round 8 journeys, the crew uncovered round 1,000 fossils-many of them sitting loosely alongside the streambed, as simple to seize as a stone.

“A tooth from a mammoth, a bone from a saber-toothed cat—we’d put them in our pouches right where we found them and keep going,” Moretti stated.

Among essentially the most shocking finds had been fossils from animals by no means earlier than documented in Central Texas.

That consists of the pampathere—an enormous, armadillo-like creature that would develop as much as seven toes lengthy and practically three toes tall.

Researchers additionally discovered proof of large floor sloths, together with huge claws from the animals that when stood as much as six toes tall.

In addition to these discoveries, the crew found saber-toothed cat tooth, child mammoth bones, and the stays of camels and mastodons.

Moretti estimates the fossils are between 70,000 and 130,000 years previous—with proof pointing they may very well be from the final interglacial, a heat interval that occurred round 100,000 years in the past over the last Ice Age.

Another clue that these fossils might belong to the final interglacial is the habitat and temperature. Ground sloths and mastodons lived in forested environments, whereas large tortoises and pampatheres trusted hotter climates to outlive. Scientists say these circumstances doubtless existed throughout hotter interglacial durations.

In distinction, throughout colder glacial durations, Central Texas was dominated by vast, open grasslands.

What’s subsequent:

Now, researchers are attempting to reply the subsequent huge query: how did the fossils get there?

“They probably are entering in a similar way we are through sinkholes, through these vertical shafts that extend down from the Edwards Plateau surface and intersect these horizontal spring channels,” says Moretti.

As the investigation continues, Moretti says discoveries like this rely closely on entry to personal land—and he’s encouraging extra landowners to companion with scientists.

“Paleontologists like me can really only operate through partnerships with private landowners,” he stated. “Big discoveries like this are still out there waiting to be made.”
