Mammoth search gives insight into the Rockies in ice age

A whole series of fossilized mammoths and mastodons and other creatures that ice age was turn at a dizzying rate in Western Colorado.


Researchers believe this is one of the most important finds of such that could be date.


The credit for this find goes Jesse Steele to construction workers, who says he pretty much "grew up on the seat" of a bulldozer.Last month, he worked at a typical urban project extend a reservoir located near Aspen/Snowmass ski resort.


"I was stripping the peat moss and noticed a few of the rib bones in load of dirt come to me", says Steele."And this is where I stopped and got out and looked at."


It was clear that this was something great.


"" It was kind of scary ", says Steele."I think it made me nervous right on the ersten.Die bone looks not like bones."

Steele, says that there was an eerie feeling him so well preserved.But then the excitement to come.


"It is a Colombian mammoth" archaeology says PhD student Brendan Asher, one of the 40 researchers from Denver Museum of nature and science that descended on the site have.


With a savvy move Asher takes a trowel and the surrounding soil removed disk slowly and so painstakingly to expose the mammoth skeleton.


"Off shaving is essentially, what we do millimeter by millimeter, very thin layers [and] levels available, what is below and potentially more bone and hopefully discover evidence - find potentially find human interactions - with this animal," says Asher.


Identification of 22 species


Compared with other findings in North America and Siberia, this site is more complete and detailed because it contains insects, plants and animals.


So far, scientists have two periods at the location identified - a 12,000 to 16,000 years old and other more than 40,000 years old.

"" We partial skeletons of many a Mastodon, the two mammoth a couple of bison - including the skull, a magnificent skull a gigantic ice age Bison with a 7-foot Horn span, "says Kirk Johnson, the Chief Curator at the Denver Museum that supervision is the dig.""We have the bones of Jefferson's ground sloths that known the highest ice age deer this animal is gefunden.Und ever in the world we have a complete skeleton."


And the list goes weiter.So far, researchers have identified at least 22 species.


The highest ice age site


Scientists not sure why time says the remains of the period so many animals at the site of one such long endete.Johnson passed the fact this site atop a mountain - rather than at the base - means the bones as time covers less sediment.


"" This is the highest ice age website,"says Johnson."And it will tell us much about what life in the Rocky Mountains during the last ice age war.Es is a window into an ice age ecosystem. we know very little about places like that, so this is really a world-class fossil site."


Researchers have cringe last month, get, are what could set off the ground before the winter in the verbracht.Jetzt move the bones of the dig site to Denver for further analysis.


And with what so far found you expect, back when the soil taut in spring.
