Two fossilised dinosaur teeth found in southern Japan are the first evidence that huge tyrannosaurs once roamed the area, it's reported.
The teeth were discovered in an 81 million-year-old layer of rock in Nagasaki Prefecture last year, and now palaeontologists have announced that they're likely from the lower jaw of a 10m (33ft) long dinosaur

UChicago collaboration unveils African dinosaur Spinosaurus

Scientists have unveiled what appears to be the first truly semiaquatic dinosaur, Spinosaurus aegyptiacus. New fossils of the massive Cretaceous-era predator reveal it adapted to life in the water some 95 million years ago, providing the most compelling evidence to date of a dinosaur able to live and hunt in an aquatic environment.

Spinosaurus fossil: 'Giant swimming dinosaur' unearthed

A giant fossil, unearthed in the Sahara desert, has given scientists an unprecedented look at the largest-known carnivorous dinosaur: Spinosaurus.
The 95-million-year-old remains confirm a long-held theory: that this is the first-known swimming dinosaur.
Scientists say the beast had flat, paddle-like feet and nostrils on top of its crocodilian head that would allow it to submerge with ease.

Tyrannosaurus tore the head off armoured prey to reach the tender neck meat.

Theirs was the immortal battle: a fierce tyrant battling a defender armed with three lethal horns and protected by a bony frill around its neck. Yet the violent fight between Tyrannosaurus and Triceratops is hardly the stuff of Hollywood hype. Tyrannosaurus bite marks are well known on the fossil bones of Triceratops but, so far, such fossils have always been studied in an isolated manner.
In a departure from this precedent, work presented last week at the Society of Vertebrate Paleontologys annual meeting in Raleigh, North Carolina, reports on an examination of numerous bite-scarred Triceratops bones and a theory of how Tyrannosaurus fed.
