Dinosaurs Current Events

A unique dinosaur species has been discovered in South Africa. Aardonyx celestae apparently walked upright on two legs most of the time, but sometimes used all four.

Were dinosaurs warm-blooded or cold-blooded creatures? This article from EARTH Magazine explains why they could have been endothermic.

Portable 3D laser technology can be used to scan fossils for data to create three-dimensional replicas. An example of this is in Glen Rose, Texas, where a dinosaur track was built into a courthouse wall.

Marks on a Tyrannosaurus rex skull indicate that the creature may have been fighting with its peers. The young dinosaur, “Jane”, was apparently bitten on the snout, causing the bones to heal asymmetrically.

This .pdf from the National History Museum of Los Angeles County announces the unveiling of Fruitadens haagarorum. Found in the Morrison Formation of Colorado, it is the smallest dinosaur discovered in North America to date. Weighing slightly less than a kilogram (2 pounds), the creature was quick and nimble, and possibly had an omnivorous diet.

A 7.5-acre site in Prince George’s County will become Maryland’s first dinosaur park. County archaeologist, Donald Creveling calls it “one of the most prolific sites for dinosaur and plant fossils east of the Mississippi River.”

Researchers at the Natural History Museum of Los Angeles County are assembling a dinosaur that is only 28 inches long and weighed about two pounds.

Some fossils found in northeastern China could be the “missing link” in pterosaur evolution. The Darwinopterus, named after Charles Darwin, has characteristics of both earlier and more recent Mesozoic reptile species.

As new fossil discoveries allow us to learn more about dinosaurs, a puzzling problem has surfaced. A dinosaur’s bone structure could change significantly between youth and maturity. It is possible that the fossils of young dinosaurs may have been mistaken as being those of a separate species. National Geographic is currently airing a show on the subject, called “Dinosaurs Decoded”.

Numerous dinosaur imprints measuring up to 2 meters in diameter and covering a distance of over 100 meters have been discovered near the village of Plagne, France.

“Samson” is the name of the third most complete tyrannosaurus skeleton ever found. He was placed up for auction in Las Vegas with the expectation that he would fetch at least $8 million – the price paid about ten years ago for a similar fossil. Bidding fizzled at $3.7 million – less than the reserve price.

A small ancestor of Tyrannosaurus rex has been discovered in China. Raptorex lived about 60 million years before T. rex and stood about 9 feet tall.

Once a name attains global popularity it can be very difficult to make a correction. A post at Everything Dinosaur explains the confusion between the names Apatosaurus and Brontosaurus.

PBS has a new children’s series titled “Dinosaur Train”. The star of the show will be Buddy, an animated Tyrannosaurus rex. Paleontologist, Scott Sampson, research curator at the Utah Museum of Natural History will be featured in live-action segments within the show.

A Tyrannosaurus rex skeleton named “Samson” will be auctioned on October 3 in Las Vegas, Nevada. In 1997 a similar Tyrannosaurus rex was purchased at auction by Chicago’s Field Museum for $8 million.

The Arenysaurus ardevoli, a duck-billed hadrosaur, may have been one of the last surviving dinosaurs before the mass extinction. It is theorized that the creature had large limb muscles which were used for swimming.

One of the largest known specimens of Tyrannosaurus Rex will be auctioned by Bonhams & Butterfields on Saturday, October 3, 2009 in Las Vegas. The skeleton is expected to bring millions of dollars.

When many people think of the Tyrannosaurus Rex, they imagine a vicious predator attacking a large Brontosaurus or Triceratops. As it turns out, T. Rex may have been more apt to pursue weaker prey, like juvenile dinosaurs and smaller species.

When fossils are stolen from a dig site, valuable information is taken along with them. Researchers are working on developing a way to link fossils with their original surroundings so that stolen fossils (and thieves) can be positively identified.

A new species of therizinosaur has been found in Utah. The Nothronychus graffami had a pot belly, a beaklike mouth, and very long, curved claws.

“Dakota”, a duck-billed hadrosaur unearthed several years ago in North Dakota, is being examined by experts from the University of Manchester. They have been able to identify cell-like structures in its mummified skin.

It appears that Cretaceous dinosaur species in both America and Australia used to dig burrows into the earth. While it is not entirely clear what the burrows were used for, two possibilities could be shelter or nesting.

Three new dinosaur fossils have been found in Western Queensland, Australia. The theropod and two sauropods have been named Banjo, Matilda and Clancy. This page links to the extensive PLoS article and other information.

About seventy paleontologists attending the North American Paleontological Convention at the University of Cincinnati took a field trip to the Creation Museum, just across the Ohio River in Petersburg, Kentucky. An article in the New York Times describes their visit.

Nathan Murphy, a well known dinosaur hunter plead guilty to removing 13 dinosaur bones from government land without permission. His sentence was four months in a halfway house and three years probation.

“Scientists have discovered a unique beaked, plant-eating dinosaur in China. The finding, they say, demonstrates that theropod, or bird-footed, dinosaurs were more ecologically diverse in the Jurassic period than previously thought, and offers important evidence about how the three-fingered hand of birds evolved from the hand of dinosaurs.” Quoted from the NSF press release.

Bonhams’ Natural History has recently auctioned two dinosaur skulls for a hefty price. The skulls of a Triceratops and Alioramus remotus both sold for about twice their estimated value.

Some dinosaur tracks found in both Scotland and the U.S. state of Wyoming are remarkably similar. Is it possible that they were made by the same species of dinosaur?

It’s difficult to know for sure how dinosaurs carried themselves, and scholars have different opinions on sauropod posture in particular. This article argues that the dinosaurs probably held their long necks in a more vertical position.

Thieves stole items from a dinosaur exhibit in Yorkshire that is used to educate children.
