Unexpected Treasures on Nebraska’s High Plains: Agate Fossil Beds National Monument

Agate Fossil Beds National Monument in Nebraska features much, much more than fossils. Bob Pahre photo. In the ranching country of western Nebraska lies a small national park unit with a big name, Agate Fossil Beds National Monument . It emphasizes two treasures, but it also holds some unexpected riches on this prairie landscape. “Agate” is named after James Cook’s Agate Springs Ranch, a privately-owned working ranch that still lies just outside the park. Cook was an adventurer of the Old West who eventually settled down in this country when it was still Indian land. A man of diverse [...]

Strudiella devonica could significantly narrow that gap in the fossil record

Strudiella devonica is an eight-millimeter invertebrate that seems likely to significantly narrow a large gap in the fossil record, specifically a period known as the Hexapoda Gap (between 385 and 325 million years ago).  Until now there have been minimal if any confirmed insect fossils found from this period.

Here are some articles with more information on this:

This is truly a great discovery that helps paint a better picture of our Earth’s natural history.

 

Egg Fossil Discovered that Links Dinosaurs to Modern Birds



Scientists Discover Fossil Egg That Links Dinosaurs To Modern Birds (via redOrbit)

It is the only dinosaur egg in the world to have an oval shape, similar to that of chicken eggs Before her death in December 2010, Nieves López Martínez, palaeontologist of the Complutense University of Madrid, was working on the research of dinosaur eggs with a very peculiar characteristic: an ovoid…

Discovery of Underground Fossil Forest Offers Answers to Climate Change

The largest fossil forest ever discovered has been unearthed in the dark and clammy depths of an Illinois coal mine. Scientists are saying it is more than fifty times larger than any other fossil forest. This fossilized forest dates back to the carboniferous era, about 307 million years ago, just before the first great forests in the world were wiped out by global warming.

According to the New York Times, the fossilized forest is located in the Springfield Coal Mine, which has been one of the nations largest energy resources for over ten years and underlies Illinois and two neighboring states. Over millions of years layers of rock have crushed the forest to varying depths of 250 to 800 feet below ground. Scientists are unsure of its exact size, but samples from the vicinity of Galatia, Illinois make them think it extends over 100 miles.

With the find of this fossil forest stretching hundreds of miles scientists will be able to undertake an analysis of the ecosystem in a way never before possible in ancient landscapes. The studies and evidence they will gather will help them predict the effects of global warming today.

“With our own CO2 rises and changes in climate, we can look at the past here and say, ‘It’s happened before’” said Scott D. Elrick, a team member of the Illinois State Geological Survey.

Disputed Tarbosaurus Dinosaur Fossil Auctioned for $1M in NYC

Tarbosaurus Fossil, Credit: Wikipedia

The Heritage Auction house recently sold a cousin of the tyrannosaurus for $1,052,500 despite a court order to not do so. The completely assembled Tarbosaurus fossil came with very little documentation, casting a shadow of speculation on where the remains were found. It seems this dinosaur fossil appeared out of thin air.

In 1955 paleontologist Evgeny Maleev found the first fossil of a Tarbosaurus in the Gobi Desert, and every specimen thereafter has also been found in Mongolia. There is little doubt where this skeleton came from, and Elbegdorj Tsakhia, President of Mongolia, questioned the legality of selling the dinosaur fossil two days before the auction. The Mongolians have strict regulations and heritage laws to prevent the poaching of fossils. All paleontology expeditions must receive formal permission and every find remains in the country, although the Mongolian Academy of Sciences makes loans to academic institutions.

Heritage Auctions is claiming the dinosaur fossil entered the United States legally and went on to sell the fossil, despite the outcry from paleontologists and the Mongolian government. Lawyer Robert Painter obtained a temporary restraining order for the sale of the Tarbosaurus from Judge Cortez. Painter actually rushed in to the auction with Cortez on the phone and Heritage Auctions President Greg Rohan asked Painter to leave and refused to speak with Cortez.

Pending the results of the legal dispute, there is still some hope that the fossil may be returned to Mongolia. The United States has returned smuggled fossils in the past, and in 2009 the US government returned to China the ancient bones of a saber-tooth cat and dinosaur eggs dating back 100 million years. Fossil poaching is a serious issue, and Heritage Auctions should have respected the wishes of the Mongolian Government.

Oldest Known Fossil of Flying Insect Discovered

Credit: Jacob Benner, Tufts University

The 300 Million year old fossil is from the Carboniferous Period. Paleoichnologists say it is likely to be an ancestor of the may fly. This is the oldest known full body impression of a flying insect ever discovered.

According to National Geographic News, fossil hunters found the imprint excavating the woods behind a shopping mall in North Attleboro, Massachusetts. Finding a specimen of this quality “is like winning the lottery,” said study leader Richard Knecht, a geology student at Tufts University.

This is such a valuable find because the nature of insect bodies. They’re usually not preserved well due their soft and fragile bodies. Scientists tend to find only the remains of insect wings because they are not easily digested by predators.

This 3 inch, ancestor of the may fly made this fossil with a near perfect impression by landing in mud for a brief second before flying away. More information and the study can be found on the oldest flying insect can be found at the Journal Proceedings of the National Academy of Sciences.
