Disputed dinosaur fossil auctioned for $1M in NYC

A fossil of a fearsome T. Rex relative has been auctioned in New York City despite the Mongolian government's objections and a judge's order blocking the sale.
Heritage Auctions says the 24-foot-long tarbosaur skeleton sold for $1,052,500 Sunday.

 Dinosaur remains found near Beauly

Archaeologists working on a dig near Beauly have uncovered what are believed to be the fossilised remains of a dinosaur.
The location is not being revealed but it is understood the large fossil was only discovered recently.

Velociraptor's last meal revealed

The bone of a large flying reptile has been found in the gut of a Velociraptor, sparking fresh discussion among palaeontologists.
Velociraptors have previously been described as "hyper predators". However, scientists suggest this pterosaur was too large to be the Velociraptor's intended prey but could have been scavenged.
The findings are published in the journal Palaeogeography, Palaeoclimatology, and Palaeoecology.

T. rex bite was world's strongest

Tyrannosaurus rex had the most powerful bite of any creature that has ever walked the Earth, say scientists.
Previous estimates of the prehistoric predator's bite suggested it was much more modest - comparable to modern predators such as alligators.
This measurement, based on a laser scan of a T. rex skull, showed that its bite was equivalent to three tonnes - about the weight of an elephant.

Baryonyx: the discovery of an amazing fish-eating dinosaur

The story of one of the most exciting dinosaur discoveries ever made in Britain began in 1983 when a huge claw bone was found by an amateur fossil hunter in a quarry around 30 miles south of London. 

In this video Angela Milner, one of the Natural History Museum fossil experts who described and named the dinosaur, explains why Baryonyx was such an amazing and significant find that led to the discovery of a whole new group of dinosaurs, the Spinosaurs.

Title: A Computational Analysis of Limb and Body Dimensions in Tyrannosaurus rex with Implications for Locomotion, Ontogeny, and Growth
Authors: John R. Hutchinson, Karl T. Bates, Julia Molnar, Vivian Allen, Peter J. Makovicky

The large theropod dinosaur Tyrannosaurus rex underwent remarkable changes during its growth from <10 kg hatchlings to >6000 kg adults in <20 years. These changes raise fascinating questions about the morphological transformations involved, peak growth rates, and scaling of limb muscle sizes as well as the body's centre of mass that could have influenced ontogenetic changes of locomotion in T. rex. Here we address these questions using three-dimensionally scanned computer models of four large, well-preserved fossil specimens as well as a putative juvenile individual. Furthermore we quantify the variations of estimated body mass, centre of mass and segment dimensions, to characterise inaccuracies in our reconstructions.

New hi-tech study finds T. rex was bigger and grew faster than previously thought

In a new study just published in the journal PLoS One, a team of scientists led by Professor John R. Hutchinson of The Royal Veterinary College, London, and Peter Makovicky, PhD, curator of dinosaurs at The Field Museum of Natural History in Chicago applied cutting edge technology and computer modeling to "weigh" five Tyrannosaurus rex specimens, including The Field Museum's iconic SUE skeleton. Their results reveal that T. rex grew more quickly and reached significantly greater masses than previously estimated.

MSU palaeontologists, colleagues discover new raptor species in dinosaur "graveyard"

A Montana State University palaeontologist and graduate student are part of a research team that unveiled a new species of raptor dinosaur on Monday, Sept. 19.
MSU doctoral student Mike Knell found the fossil in southern Utah in one of the last pristine dinosaur graveyards in the United States.

Spinosaurus: the largest land predator known

Spinosaurus was a dinosaur that lived in the late Cretaceous period in what is today North America.
At 17m long, and weighing 11 tonnes, it is the largest land predator known, one that specialised in eating fish.

MSU researchers say small Asian dinosaur actually a juvenile tyrannosaur, not separate species

The small-bodied tyrannosaur named Raptorex kriegsteini - about 10 feet long -- was named in 2009 by University of Chicago professor Paul Sereno and colleagues, and was described as having originated during the Lower Cretaceous of China, around 130 million years ago. The Raptorex was important because it seemed to show that characteristic features of tyrannosaurids, such as the short two-fingered arms, were acquired some 50 million years before previously thought. As a result, Tyrannosaurus was relegated to being just a particularly large, brutish version of a much older body plan.
However, Museum of the Rockies researcher Denver Fowler and colleagues showed in a paper published June 29 in the journal PLoS One that key supporting evidence was misinterpreted by the original Raptorex authors, and that the old ideas might not have been so wrong after all.
