Paleontologists uncover prehistoric Colorado resident that lived along dinosaurs

A crew of paleontologists running in northwest Colorado have came upon Heleocola piceanus, a mammal that was once alive all through the age of the dinosaurs.

RANGELY, Colo. — College of Colorado Boulder introduced Wednesday {that a} crew of paleontologists running within the northwest nook of Colorado have came upon a “swamp dweller” that was once alive all through the age of the dinosaurs.

The researchers, led by way of CU Boulder’s Jaelyn Eberle, printed their findings on PLOS ONE, the media liberate says.

The crew unearthed a up to now unknown mammal fossil close to Rangely that is called Heleocola piceanus. “Heleocola” more or less interprets to “swamp dweller.” They have been in a position to spot it from a work of jawbone and 3 molar enamel.

The brand new mammal will have weighed round two kilos. It was once across the dimension of a muskrat that can have scurried in regards to the swamps with the dinosaurs, making it greater than maximum mammals from the Overdue Cretaceous duration. 

It lived in Colorado round 70 to 75 million years in the past when an inland sea lined massive parts of the American West. Eberle stated the brand new animal is a cousin to modern day marsupials and perhaps ate vegetation with a couple of bugs or different small animals thrown within the combine.

Different creatures within the space have been turtles, duck-billed dinosaurs and large crocodiles that can have flourished in and round marshes and estuaries. They ate wetland plants, fish and extra, the media liberate says.

“Colorado is a brilliant position to seek out fossils, however mammals from this period of time have a tendency to be lovely uncommon,” stated Eberle, curator of fossil vertebrates on the CU Museum of Herbal Historical past and professor within the Division of Geological Sciences. “So it’s in reality neat to look this slice of time preserved in Colorado.”

The invention is helping to color a greater image of a previous Colorado that will be unrecognizable to citizens nowadays.

Paleontologists John Foster and ReBecca Hunt-Foster, co-authors of the brand new find out about, were coming to this a part of Colorado to dig up fossils each and every summer season for roughly 15 years.

“The area may have appeared roughly like Louisiana,” stated Hunt-Foster, a paleontologist at Dinosaur Nationwide Monument in Utah and western Colorado. “We see numerous animals that have been dwelling within the water moderately thankfully like sharks, rays and guitarfish.”

The fossil was once amassed from the website online in 2016 the place Foster recollects seeing the little bit of mammal jaw emerge from the sandstone. The fossil measured about an inch lengthy.

“I stated, ‘Holy cow, that’s massive,’” stated Foster, a scientist on the Utah Box Space of Herbal Historical past State Park Museum in Vernal, Utah.
