The rise of the tyrants of the South The stubby arms of Tyrannosaurus rex obviously weren't designed for hand-to-hand combat. However, the abelisaurids of the Southern hemisphere were even less well equipped in that department—and upper limb reduction began very early in their evolution. When Tyrannosaurus and its relatives roamed North America and Asia, the abelisaurids occupied a similar niche in Patagoniaand other areas ofGondwanaland. They were the dominant predators in the...

A massive tail muscle made a 23-foot-long carnivorous dinosaur one of the fastest-running (and deadliest) hunters of its era, a University of Alberta researcher has discovered. According to UPI reports on Friday, Scott Persons, a graduate student in paleontology at the university, used 3D computer models of re-create the tail muscles of the twin-horned Carnotaurus. Persons discovered that the dinosaur's tail had "a series of tall rib-like bones that interlocked with the next pair in...

U.S. and Chinese scientists say their discovery of a beaked, plant-eating dinosaur fossil shows how birds' three-fingered claws evolved from dinosaurs. The researchers said their finding also demonstrates theropod, or bird-footed, dinosaurs were more ecologically diverse in the Jurassic period than previously thought. This new animal is fascinating, and when placed into an evolutionary context it offers intriguing evidence about how the hand of birds evolved, said Professor James Clark of...

Scientists have uncovered a beaked dinosaur in China that is providing new clues into how birds' hands evolved to develop fingers.Writing in the journal Nature, scientist James Clark of George Washington University and Xu Xing of the Chinese Academy of Science's Institute of Vertebrate Paleontology and Paleoanthropology in Beijing detailed the new discovery, which was found amidst 159-million-year-old deposits in the Junggar Basin of Xinjiang."This finding is truly exciting, as it changes...

Paleontologists have discovered fossils in Africa's Sahara Desert of two new meat-eating dinosaurs that walked the earth 110 million years ago during the Cretaceous Period.   The dinosaurs were discovered in 2000 during an expedition led by University of Chicago paleontologist Paul Sereno.  Sereno and co-author Stephen Brusatte of the University of Bristol reported the discovery in the journal Acta Palaeontologica Polonica. In their report, they said the fossils provide a...

Rajasaurus, meaning “Kingly lizard,” is a genus of abelisaurian theropod dinosaur that lived on the land masses associated with the super-continent Gondwanaland. The first fossils were discovered by Suresh Srivastava from the Geological Survey of India (GSI) between 1982 and 1984. Excavated from the Narmada River valley in Rahioli in the Kheda district of Gujarat, India, the find was announced as a new genus of dinosaur by both American and Indian scientists in August 2003. The type...

Majungasaurus, meaning “Mahajanga lizard,” is a genus of abelisaurid theropod dinosaur from the Late Cretaceous Period of what is now Madagascar (70 to 65.5 million years ago). The type species is M. crenatissimus. Majungasaurus was first described by French paleontologist Charles Depéret in 1896 from a fossil that included two teeth, a claw, and some vertebrae discovered along the Betsiboka River by a French army officer. Depéret referred to these fossils as belonging to...

Skorpiovenator is a genus of abelisaurid theropod dinosaur from the Cenomanian Stage of the Late Cretaceous Period of Argentina (about 93 million years ago). It was discovered in the lower part of the Huincul Formation in Patagonia. The type specimen, S. bustingorryi, was described and named by Canale, Scanferla, Angolin, and Novas in 2009. It is known from a single, nearly complete skeleton missing only part of the tail and most of the forelimbs. Skorpiovenator is derived from the Greek...

Rugops, meaning "wrinkle face", was a genus of theropod dinosaur from the Cenomanian stage of the Late Cretaceous Period (95 million years ago). It inhabited what is now Africa. The skull of the Rugops was found in Niger in 2000 and was a critical breakthrough in the understanding of theropods in that area. Rugops was 24 to 30 feet in length and stood about 8 feet high at the hip. It was a large carnivore, but based on the skull having had armor or scale plating, Dr. Paul Sereno, who led...

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...
