An uncommon discover in southwest Iowa near to the East Nishnbotna River near Shenandoah was revealed a week earlier.
While the specimen itself, the skull of a sabertooth cat, was discovered in 2017, Matthew Hill, associate teacher of sociology at Iowa State, said research study of this kind takes some time.
What Hill called an unanticipated discovery had himself and David Easterla, teacher emeritus of biology at Northwest Missouri State University, finding out about the predators hypothesized to have actually been extinct for around 13,000 years.
Hill said the discovery was uncommon on many levels.
“First of all, to find a complete skull of this animal is extremely rare, especially outside of the tar pits in La Brea,” Hill said. “And then its physical condition is really spectacular. It’s like the animal died yesterday almost. There’s a little bit of damage to it but minimal. It does not affect the scientific value of the specimen.”

The LaBrea Tar Pits, where Easterla said a range of fossils might be discovered, lie in California. He said the factor is that when it rains, tar is much heavier, and the water collects on top of the tar pits, ending up being a natural trap for animals roaming in to consume the water. The predators — at the top of the food cycle, so they are less in numbers — likewise get caught in the tar pits pursuing victim.
Hill and Easterla said this is the very first fossil record of a sabertooth cat specimen discovered in Iowa, with Hill keeping in mind just about 70 tape-recorded throughout the United States. He said separated bones, random teeth and fragmentation specimens represent most of those.
Hill said it would not have actually been unusual for a sabertooth cat to have actually strolled the land now called southwest Iowa. In studying the specimen, Hill and Easterla found it was a young male, around 2 to 3 years of ages.
“So that means that we had mom and dad out there somewhere two years before,” Hill said.
Easterla said they might identify the cat had actually not maturated since of bone in the skull that had actually not entirely merged.
Easterla said it is thought that the sabertooth cat strolled throughout North America.
“I’ll be truthful, I never dreamed of a sabertooth cat skull turning up in our area,” he said.
So why is discovering a fossil record of the sabertooth cat exceptionally uncommon?
“Large carnivores like this cat are extremely rare in the fossil record because, in health ecosystems, the prey outnumbers the predators, and that means that the chances of a large predator like this dying, being stored in the fossil record for who knows how long and then discovered somehow are much slimmer compared to say a bison bone or what have you,” Hill said. “So there’s fewer of these animals to die, fewer of them to be buried and preserved, and fewer of them to be found.”
Hill said this specific sabertooth cat specimen was approximated to weigh around 550 pounds at its time of death. If it has actually maturated in prime physical condition, he said it might have reached 600 pounds or surpassed that weight.
Unsure of the cause of death Hill said a damaged tooth where the saber goes into the gum had attributes that recommended the tooth lived when it broke. So he said they might hypothesize he might have been hurt in removing victim, however there is no other way to be sure, which is just one possibility without any proof.
Using radiocarbon dating, Hill said the specimen dates to 13,500 years earlier, keeping in mind that the cat was “one of the last of its kind to walk the planet.”
Sabertooth cats are said to have actually strolled the earth throughout the Pleistocene date, or some describe it as the glacial epoch.
Esterla said he acknowledged the significance of discovering the skull and said it should be cleaned up, dried and a protect covering used prior to anything else might take place. He said that as soon as exposed to oxygen, it can break down rapidly. Then and just then might the research study begin.
Esterla and Hill worked side by side, determining and studying the skull, with Esterla keeping in mind “this isn’t a one-person research project.”
Hill said studying the sabertooth cat specimen included extensive, detailed, comprehensive basic documents, consisting of measurements of lots of functions of the skull, permitting them to compare it to other specimens discovered in other places.
He explained it as a basic morphological description of the specimen.
“So some things we can measure and some things we can’t measure, but we can describe them,” Hill said. “We also have to be able to describe the physical condition of the specimen in something that’s understandable to the scientific community.
You have to have a really careful eye for detail to pick up really subtle things that are preserved on the cranium that may or may not provide meaningful insights into how the animal lived and died.”
Hill expects this will be the only fossil record of a sabertooth cat he will have the opportunity to study, stating, “chances of another one being found in my lifetime are slim to none and slim just left the room.” Reiterating how uncommon they are to discover.
While research study arises from the previous 6 years of the skull have actually been launched, Esterla said the skull is such a substantial discover that research study will continue. He hopes that tarter on the teeth will help them identify what the sabertooth cat might have consumed.
“Dr. Esterla and I have really appreciated the support that we’ve received from the communities in southwestern Iowa,” Hill said.
