Paleontologists have discovered the remains of a large meat-eating dinosaur with a breathing apparatus much like a modern bird, fortifying the link between birds and dinosaurs and helping to explain the evolution of birds' unique system of breathing. The scientists said the specimen, pulled from 85-million-year-old rock along the banks of Rio Colorado in Argentina's Mendoza Province, was a 33-foot-long (10 meter), two-legged predator that weighed as much as an elephant and likely had...

Aerosteon, meaning "air bone", is a genus of theropod dinosaur from the Santonian age of the Late Cretaceous Period (84 million years ago). It lived in what is now Argentina. It was discovered in 1996 in the province of Mendoza. The type, and only known, species is A. riocoloradensis. Its specific name refers to the Rio Colorado Formation where it was found. Aerosteon is known from a single tooth, some cranial bones, partial vertebrae from the neck, back, and sacrum, some ribs, and...

Labocania, meaning "red lips"(named for the La Bocana Roja Formation), is a genus of theropod dinosaur from the Campanian age of the Late Cretaceous Period (70 million years ago). It lived in what is now Baja California, Mexico. The type species, L. anomala, was described in 1974 by Ralph Molnar. Labocania is known only from fragmentary remains, and its physical characteristics are not well known. There is some speculation that it may be closely similar to tyrannosaurid dinosaurs, but...

Megaraptor, meaning "giant thief", is a genus of dinosaur from the Late Cretaceous Period that lived in what is now Argentina. This was one of the largest carnivorous dinosaurs of all time, and once believed to be the largest dromaeosaur ever found. After further research, this was ruled to be either a carnosaur or spinosaur. Initially being described as a large dromaeosaur due to its similarities to dromaeosaurid dinosaurs, this dinosaur is now placed elsewhere, although the actual...

It was the first carnivorous dinosaur to be discovered in Antarctica. It was also the first dinosaur from Antarctica to be officially named. Dr. William Hammer and his team unearthed the dinosaur during the...
