Dinosaurs like Velociraptors owe their fearsome reputation to the way they breathed, according to a UK study.
They had one of the most efficient respiratory systems of all animals, similar to that of modern diving birds like penguins, fossil evidence shows.
It fuelled their bodies with oxygen for the task of sprinting after prey, say researchers at Manchester University.

The discovery of the first fossil tracks belonging to a large, carnivorous dinosaur in Victoria, Australia has shed new light on the fact that dinosaurs lived in a polar environment during the Cretaceous Period, when Australia was still joined to Antarctica and was closer to the South Pole.
The three separate dinosaur tracks are about 14 inches long, and show at least two or three partial toes.
Palaeontologists from Emory University (the US) and Monash University and the Museum of Victoria (both Australia), believe large carnivorous dinosaurs (theropods) made the tracks on river floodplains about 115 million years ago during the Cretaceous Period.
Senior lecturer in environmental studies at Emory, Anthony Martin said, based on track sizes, the dinosaurs were 4.6 to 4.9 feet tall at the hip, large by human standards, but about 20 percent smaller than Allosaurus, a large theropod from the Jurassic Period.

Giant footprints from meat-eating dinosaurs have been discovered on Victoria's south-east coast, providing proof the beasts roamed the area millions of years ago.
The three fossil tracks found near Inverloch show at least two or three partial toes about 35 centimetres long, which suggest the creatures were up to 1.5 metres tall at the hip.
While bone fragments from carnivorous dinosaurs have been found in Victoria, experts say the footprints prove "beyond doubt" they were actually living in the area.

Part of the problem surrounding the arms of Tyrannosaurus was that no one knew for sure what they looked like until the discovery of lower limb bones in 1989. The initial discoveries, two skeletons found by Barnum Brown at the beginning of the 20th century, did not preserve the radius, ulna, metacarpals, or digits, and so some of the earliest reconstructions envisioned Tyrannosaurus with three fingers like the Jurassic Allosaurus. Relatives of Tyrannosaurus discovered just before or some time after Brown's significant finds (like Lawrence Lambe's discovery of Gorgosaurus) showed that tyrannosaurids possessed two fingers, not three.

A dinosaur hunter has discovered what he hopes is the world's first footprint of the savage Tyrannosaurus rex.
Dr Phil Manning, of Manchester University, found the metre-square print in the arid badlands of North America - all of 67 million years after its owner left it there.

A British palaeontologist has found what he thinks is a preserved Tyrannosaurus rex footprint.
The metre-square, three-toed track was discovered in the Badlands of Montana, US, an arid landscape that has yielded many of the finest dinosaur specimens.
Dr Phil Manning, from the Manchester Museum, University of Manchester, first saw the impression last year.
He returned to the US in July to study the print further, and now plans to publish details in a science journal.

A fossil hunter has discovered what is believed to be a footprint left 67 million years ago by a Tyrannosaurus rex.
Phil Manning, of the University of Manchester, found the print, 76cm (29.9in) long, in rock at Hell Creek, Montana, US. If confirmed it will be the only known T. rex print.

People have been trying to find T. rex tracks for a hundred years - Dr Phil Manning.

His discovery is shown on Inside Out North West on BBC One tonight. While it could be T. rex or a Nanotyrannus, the size suggests the former is more likely.

For Sue, becoming a fossil wasn't easy.

"To get fossilised is kind of like winning the lottery. It takes a special set of circumstances" - Jacksonville State University's Dr. Roger Sauterer, who will give a lecture on dinosaurs at the Anniston Museum of Natural History Sept. 27.

The ferocious Velociraptor, made famous in the movie Jurassic Park, was probably covered in feathers.
A re-assessment of a fossil forearm unearthed in Mongolia in 1998 has revealed an array of small bumps.
In modern birds, such "quill knobs" are the locations where secondary feathers, the flight or wing feathers, are anchored to the bone with ligaments.
The American Museum of Natural History and the Field Museum of Natural History report their study in Science magazine.

In the summer of 2000, David Gillette, Colbert curator of vertebrate palaeontology at the Museum of Northern Arizona, was getting ready to return to camp after a long day of field excavation.
Busy excavating bones of a plesiosaur, an ancient sea reptile, in the Tropic Shale in the desert of southern Utah, Gillette was suddenly handed an odd bone by Merle Graffam, a crew member and resident of the town of Big Water near the site.

Some palaeontologists use tweezers and scalpels for excavating prehistoric fossils. When Peter Larson goes dinosaur hunting, he clears his sites with a Bobcat mini-bulldozer and digs up promising bones with the bayonet from an M16 rifle.
His methods have upset numerous academics, but Larson has become the worlds most successful dealer in the bones of Tyrannosaurus rex and countless other prehistoric specimens retrieved from the great western plains of Montana, Wyoming and South Dakota.
