Museum officials in Japan say fossilized teeth from an ancestor of the tyrannosaurus have been found in the Hyogo Prefecture. Museum of Nature and Human Activities officials said the teeth found in Tamba were inside strata thought to be up to 140 million years old, Kyodo reported Sunday. Curator Haruo Saegusa said the fossils indicate the carnivorous dinosaur they came from was likely nearly 16.5 feet long. Saegusa added if the fossils' age was similar to that of the strata it was discovered...

A team of researchers led by a North Carolina State University scientist has found soft tissue on a dinosaur skeleton. The team was led by Professor Mary Schweitzer, who in 2005 found soft tissue in the fossilized bone of a 68-million-year old Tyrannosaurus rex, The (Raleigh, N.C.) News & Observer reported Thursday. The findings will be published this week in the journal Science. As was the case with the T.

An international team of researchers uncovered a treasure trove of dinosaur fossils in China that may help paleontologists better understand the evolution of Tyrannosaurus rex.

A dinosaur skeleton that vanished from Mongolia likely was sold on the black market, says a fossil hunter from the Cleveland Museum of Natural History. The broken skeleton, found in the Gobi desert, was to be reassembled as a centerpiece for the Museum, said Michael Ryan, the Museum's head of vertebrate paleontology. It would have been the most significant chunk of Tarbosaurus in North America.

By Lipkin, Christine Sereno, Paul C; Horner, John R INTRODUCTION OSSIFIED CLAVICLES, either as paired elements or as a median furcula, have been recorded in all major clades of dinosaurs, including ornithischians, sauropodomorphs, and theropods (Bryant and Russell, 1993).

The remains of a giant, birdlike dinosaur as tall as the formidable tyrannosaur have been found in China, a surprising discovery that indicates a more complicated evolutionary process for birds than originally thought, scientists said Wednesday.

Even the powerful tyrannosaurs seem to have encountered a midlife crisis. Once they made it to about age 2 they could take on just about any other predator and had very little mortality until they reached sexual maturity in their teens.

Daspletosaurus

Daspletosaurus, meaning “frightful lizard” is a genus of tyrannosaurid theropod dinosaur that resided in western North America between 77 and 74 million years ago, during the Late Cretaceous Period. Fossils of the only named species were found in Alberta, although other possible species from Alberta and Montana wait for description. Daspletosaurus is closely related to the much larger and more current Tyrannosaurus. Like most of the known tyrannosaurids, it was a multi-ton bipedal...

Tarbosaurus

Tarbosaurus, meaning “alarming lizard” is a genus of tyrannosaurid theropod dinosaur that thrived in Asia about 70 million years ago, at the end of the Late Cretaceous Period. Fossils have been uncovered in Mongolia, with more incomplete remains found further afield in parts of China. Many species have been named, although, modern paleontologists recognize only one, T. bataar, as legitimate. Like most tyrannosaurus, Tarbosaurus was a sizeable bipedal predator, weighing up to six...

Tyrannosaurus

Tyrannosaurus, meaning “tyrant lizard,” was a genus of theropod dinosaur from the Late Cretaceous Period (68 to 65 million years ago). It was among the last non-avian dinosaurs to exist prior to the Cretaceous-Tertiary extinction event. Perhaps the most famous Tyrannosaurus species, T. rex, was named in 1905 by Henry Fairfield Osborn, president of the American Museum of Natural History (AMNH). Teeth belonging to Tyrannosaurus were first discovered in 1874 by A. Lakes near Golden...

Xiongguanlong, named after the city of Jiayuguan in northwestern China, is a genus of tyrannosauroid dinosaur from the Aptian to Albian ages of the Early Cretaceous Period (100 to 125 million years ago). The type species, X. baimoensis, was described in 2009 by a group of researchers from China and the USA. The species name, baimoensis, means "white ghost", after "white ghost castle", a rock formation near where the fossil was found. Xiongguanlong was a medium-sized tyrannosauroid. It...

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...
