Students discover new species of raptor dinosaur in Inner Mongolia

1000pa (Mar. 19, 2010) — A new species of dinosaur, a relative of the famous Velociraptor, has been discovered in Inner Mongolia by two PhD students.

The exceptionally well preserved dinosaur, named Linheraptor exquisitus, is the first near complete skeleton of its kind to be found in the Gobi desert since 1972, and will help scientists work out the appearance of other closely related dinosaur species.

Linheraptor is in the Dromaeosauridae fa...

From crickets to whales, animal calls have something in common

1000pa (Jan. 6, 2010) — Scientists who compare insect chirps with ape calls may look like they are mixing aphids and orangutans, but researchers have found common denominators in the calls of hundreds of species of insects, birds, fish, frogs, lizards and mammals that can be predicted with simple mathematical models.

Compiling data from nearly 500 species, scientists with the University of Florida and Oklahoma State University have found...

Fossil shelved for a century reworks carnivore family tree: Limbs changes understanding of early carnivore locomotion

1000pa (Dec. 23, 2009) — More than a hundred years after its discovery, the limbs and vertebrae of a fossil have been pulled off the shelf at the American Museum of Natural History to revise the view of early carnivore lifestyles. Carnivores -- currently a diverse group of mostly meat-eating mammals like bears, cats, raccoons, seals, and hyenas -- had been considered arboreal in their early evolutionary history. But now that the skeleton...

Early carnivorous dinosaur crossed continents, alters evolutionary tree

1000pa (Dec. 10, 2009) — Did the first dinosaurs wander across continents or stay put where they first evolved? The first dinosaurs evolved 230 million years ago when the continents were assembled into one landmass called Pangea. The question of early dinosaur movements remained unclear until the discovery of some exciting new fossils.

In the Dec. 11, 2009, issue of Science, a team of paleontologists presents the 213-million-year-old...

Earliest Tyrannosauroid rediscovered in museum collection

1000pa (Jan. 6, 2010) — Tyrannosaurus rex and related large carnivorous dinosaurs together form the family Tyrannosauridae. A long forgotten fossil skull in the collections of the Natural History Museum in London has now provided crucial clues to the early stages of the lengthy evolutionary history of these fearsome predators. Almost a century after its discovery, the specimen, named Proceratosaurus, has now been recognized as the oldest...

Terrible Teens Of T. Rex: Young Tyrannosaurs Did Serious Battle Against Each Other

1000pa (Nov. 2, 2009) — We all know adolescents get testy from time to time. Thank goodness we don't have young tyrannosaurs running around the neighborhood.

In a new scientific paper, researchers from Northern Illinois University and the Burpee Museum of Natural History in Rockford report that adolescent tyrannosaurs got into some serious scraps with their peers.

The evidence can be found on Jane, the museum's prized juvenile Tyrannosaurus...

New Analyses Of Dinosaur Growth May Wipe Out One-third Of Species

1000pa (Oct. 31, 2009) — Paleontologists from the University of California, Berkeley, and the Museum of the Rockies have wiped out two species of dome-headed dinosaur, one of them named three years ago -- with great fanfare -- after Hogwarts, the school attended by Harry Potter.

Their demise comes after a three-horned dinosaur, Torosaurus, was assigned to the dustbin of history last month at the Society of Vertebrate Paleontology meeting in...

Rare Evidence Of Dinosaur Cannibalism: Meat-Eater Tooth Found In Gorgosaurus Jawbone

1000pa (Oct. 7, 2009) — University of Alberta researcher Phil Bell has found 70 million year old evidence of dinosaur cannibalism. The jawbone of what appears to be a Gorgosaurus was found in 1996 in southern Alberta. A technician at the Royal Tyrell Museum found something unusual embedded in the jaw. It was the tip of a tooth from another meat-eating dinosaur.

Bell, a paleontology PhD candidate, says discovery of the tooth shows that a...

Bizarre New Horned Tyrannosaur From Asia: Carnivorous But Smaller T. Rex Relative 'Like Ballerina'

1000pa (Oct. 5, 2009) — Just a few weeks after tiny, early Raptorex kriegsteini was unveiled, a new wrench has been thrown into the family tree of the tyrannosaurs. The new Alioramus altai — a horned, long-snouted, gracile cousin of Tyrannosaurus rex — shared the same environment with larger, predatory relatives.

A paper published this week in the Proceedings of the National Academy of Sciences describes this exceptionally well-preserved...

Tiny Tyrannosaur: T. Rex Body Plan Debuted In Raptorex, But 100th The Size

1000pa (Sep. 17, 2009) — A 9-foot dinosaur from northeastern China had evolved all the hallmark anatomical features of Tyrannosaurus rex at least 125 million years ago.

University of Chicago paleontologist Paul Sereno and five co-authors describe the newly discovered dinosaur in the Sept. 17 Science Express, advanced online edition of the journal Science.

Raptorex shows that tyrannosaur design evolved at "punk size," said Sereno, a National...

Chicken-hearted Tyrants: Predatory Dinosaurs As Baby Killers

1000pa (Aug. 7, 2009) — Two titans fighting a bloody battle – one that often turns fatal for both of them. This is how big predatory dinosaurs like Tyrannosaurus are often depicted while hunting down their supposed prey, even larger herbivorous dinosaurs. The fossils, though, do not account for that kind of hunting behavior but indicate that theropods, the large predatory dinosaurs, were hunting much smaller prey.

Dr. Oliver Rauhut,...

Reexamination Of T. Rex Verifies Disputed Biochemical Remains

1000pa (July 31, 2009) — A new analysis of the remains of a Tyrannosaurus rex (T. rex) that roamed Earth 68 million years ago has confirmed traces of protein from blood and bone, tendons, or cartilage. The findings, scheduled for publication in the Sept. 4 issue of the Journal of Proteome Research, is the latest addition to an ongoing controversy over which biochemical remnants can be detected in the dinosaur.

In the study, Marshall Bern,...

Largest Carnivorous Dinosaur Tooth Ever Found In Spain

1000pa (June 22, 2009) — Researchers from the Teruel-Dinópolis Joint Palaeontology Foundation have compared an Allosauroidea tooth found in deposits in Riodeva, Teruel, with other similar samples. The palaeontologists have concluded that this is the largest tooth of a carnivorous dinosaur to have been found to date in Spain.

The features and size of the 9.83cm tooth provide key information needed to identify its former owner. The researchers are in no doubt – it was a large...

Beaked, Bird-like Dinosaur Tells Story Of Finger Evolution

1000pa (June 18, 2009) — Scientists have discovered a unique beaked, plant-eating dinosaur in China. The finding, they say, demonstrates that theropod, or bird-footed, dinosaurs were more ecologically diverse in the Jurassic period than previously thought, and offers important evidence about how the three-fingered hand of birds evolved from the hand of dinosaurs.

The discovery is reported in a paper published in the June 18 edition of the...

Discovery Raises New Doubts About Dinosaur-bird Links

1000pa (June 9, 2009) — Researchers at Oregon State University have made a fundamental new discovery about how birds breathe and have a lung capacity that allows for flight – and the finding means it's unlikely that birds descended from any known theropod dinosaurs.

The conclusions add to other evolving evidence that may finally force many paleontologists to reconsider their long-held belief that modern birds are the direct descendants of...

Dynamite Used To Reveal New Layer Of Dinosaur Fossils

1000pa (Apr. 29, 2009) — What do you do when you have a fossil quarry that has yielded some of the most important and rarest of dinosaur fossils in North America, but the fossil-bearing layer of rock is tilted at 70 degrees and there is so much rock that not even jackhammers can get you to the fossils any longer?

That was the problem facing Dinosaur National Monument at a Lower Cretaceous dinosaur quarry -- the one that has produced the only complete brontosaur skulls from the...

Tyrannosaur 'Missing Link' Among New Dinosaurs From China

1000pa (Apr. 22, 2009) — During the summers of 2006 and 2007, an international team of researchers from China and the United States excavated a treasure trove of dinosaur skeletons from Early Cretaceous rocks in the southern part of the Gobi Desert near the ancient Silk Road city of Jiayuguan, Gansu Province, China. Two of their discoveries represent new species of theropod dinosaurs.

The new species are described in the Proceedings of the...

Mini Dinosaurs Prowled North America

1000pa (Mar. 17, 2009) — Massive predators like Albertosaurus and Tyrannosaurus rex may have been at the top of the food chain, but they were not the only meat-eating dinosaurs to roam North America, according to Canadian researchers who have discovered the smallest dinosaur species on the continent to date. Their work is also helping re-draw the picture of North America's ecosystem at the height of the dinosaur age 75 million years ago.
