A new giant carnivorous dinosaur from the cretaceous of Patagonia
Article Abstract:
A new giant carnivorous dinosaur, Giganotosaurus carolinii, was found in Argentina, dispelling the belief that large, flesh-eating dinosaurs were limited to the Northern Hemisphere. It is possibly the largest predatory dinosaur, characterized by a proportionally low skull, robust vertebrae and hind limbs and a reduced shoulder girdle, while it weighed an estimated six to eight tons and was 12.5 meters long. This dinosaur shares more characteristics with tetanurans than ceratosaurs, and most likely developed in a similar environment as the Tyrannosaurus.

Dinosaur nests at the sea shore
Article Abstract:
An abundance of dinosaur eggs and nests sites found at beach deposits of the Arenisca de Aren Formation distributed over 15 square kilometers present clear cut evidence for dinosaur nesting at a sea shore. Study of the sites suggest that dinosaurs nested in the open sand sediment. Large bone pieces, small crushed bones, and a nearly whole skeleton of a small lizard and land snails were found besides a large number of egg shell pieces at the site.

Brooding with the best
Article Abstract:
A well-preserved oviraptor specimen, found at Ukhaa Tolgod in the south-central Gobi desert in Mongolia, presents the first evidence of birdlike brooding behavior in a non-avian dinosaur. The skull, vertebral column and sections of the hindlimb are missing. The position of the belly over its nest and the folding of the hind legs indicates that brooding involves squatting above the eggs. Around 15 eggs are present beneath the mother.
