New Species Of Torvosaurus Was Largest European Land Predator
2014-03-06 08:08:06

Lawrence LeBlond for redOrbit.com - Your Universe Online Fossils of Torvosaurus, a large Jurassic-era theropod predator, were first unearthed in North America in 1971, later being named Torvosaurus tanneri. Examples of this dinosaur had not existed elsewhere until 2000, when paleontologists discovered another Torvosaurus fossil in Europe. The discovery, which came from a site just north of Lisbon, Portugal, led scientists to initially assume the remains were that of T. tanneri. However,...

Study: Allosaurus Ate Less Like A Crocodile, More Like A Falcon
2013-05-22 10:42:47

April Flowers for redOrbit.com — Your Universe Online To dismember its prey, the mighty Tyrannosaurus rex thrashed its massive head from side to side. T. rex´s smaller cousin, the Allosaurus, was a more dexterous hunter and tugged at prey more like a modern day falcon, a new study from Ohio University shows. "Apparently one size doesn't fit all when it comes to dinosaur feeding styles," said Ohio University paleontologist Eric Snively. "Many people think of Allosaurus...

Scientists' find describes how one family of dinosaurs came to look like birds--independent of birds Through an expedition to the Gobi Desert of China, scientists have solved the puzzle of how one group of dinosaurs came to look like birds--independent of birds. The discovery extends the fossil record of the family Alvarezsauridae--a bizarre group of bird-like dinosaurs with a large claw on the hand and very short, powerful arms--back 63 million years, further distancing the group from birds...

Scientists in Australia have reported the discovery of three new species, including one agile predator that lived 98 million years ago.Writing in the peer-reviewed journal, PLoS ONE, Scott Hocknull and colleagues at the Queensland Museum and the Australian Age of Dinosaurs Museum of Natural History noted the discovery of two large herbivorous sauropods and one carnivorous theropod in the Winton Formation in eastern Australia.Australia doesn't have a noteworthy fossil record, and many...

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 ancient, meat-eating dinosaurs, OSU researchers say."It's really kind of...

New study on hadrosaur bones shows fast growth, reproduction rates With long limbs and a soft body, the duck-billed hadrosaur had few defenses against predators such as tyrannosaurs. But new research on the bones of this plant-eating dinosaur suggests that it had at least one advantage: It grew to adulthood much faster than its predators, giving it superiority in size. In a study published online today in the Proceedings of the Royal Society of London B: Biological Sciences, scientists...

By Brian Maffly, The Salt Lake Tribune Jun. 23--HANKSVILLE -- An ancient river, which probably dried up one season, only to swirl and surge with monsoonal violence the next, once braided through this area just southeast of what is now Utah's San Rafael Swell. The river must have slowed here, shedding its load of sand, silt, gravel, trees, clams and dinosaur carcasses, dismembered chunks of big lizards that lived 145 to 150 million years ago. Locals had known this area as a boneyard...

A team of Illinois scientists looking for fossils of big dinosaurs in Utah's Morrison limestone struck pay dirt last month, opening the possibility of a major dinosaur quarry outside Hanksville. In recent weeks, the group, representing the Burpee Museum of Natural History, uncovered "a logjam" of 148-million-year remains of as many as six dinosaur species and massive coniferous trees so well preserved you can feel their bark and read their tree rings. And that's just scratching the surface,...

Colorado Springs has a dinosaur to call its own, a beast that's never been found anywhere else in the world. Scientists planned to announce Saturday at Garden of the Gods that century-old assumptions about a dinosaur skull found in the park in the late 1800s are wrong. The fossils don't belong to the type of dinosaur -- the camptosaurus -- that early bone hunters thought it did. It seems the skull fragments belong to a dino that's new to science, a conclusion that sent ripples through the...

Medullary tissue lines the bones of modern birds for only a few weeks when they are producing eggs. That same tissue has recently been found in three dinosaur fossils. These dinosaurs, an Allosaurus, Tenontosaurus and Tyrannosaurus, were aged 8, 10, and 18. This revelation shines some light on the sexuality of dinosaurs, with reproductive maturity being earlier than researchers previously believed. Sarah Werning and Andrew Lee, graduate students at the University of California, Berkely, when...

Stegosaurus
2012-06-12 19:39:25

Stegosaurus, meaning “roof lizard,” is a genus of stegosaurid armored dinosaur from the Kimmeridgian to early Tithonian stages of the Late Jurassic Period (145 mya) in what is now western North America. It was first discovered from a bone bed in the Morrison Formation in Morrison, Colorado, and was first described in 1877 by Othniel Charles Marsh. These first fossils became known as the type species S. armatus. Marsh initially believed the remains were from an aquatic turtle-like...

Othnielosaurus is a genus of ornithiscian dinosaur from the Late Jurassic Period (155 to 148 million years ago). It lived in what is now the western United States. It was formerly assigned to the genus Laosaurus. It is now named in honor of famed paleontologist Othniel Charles Marsh. This genus was coined to contain the fossils formerly included in Othnielia, which is based on remains that may be too sparse to hold a name. Decades have been spent on research to untangle the taxonomy left...

Afrovenator, meaning "African hunter" is a genus of theropod dinosaur from the Early Cretaceous Period (136 to 125 million years ago) that lived in northern Africa. Its remains were discovered in Niger in the Tiourarén Formation. It is known from a single nearly complete specimen. Only one named species is known, A. abakensis. The species name comes from the area it was found in Africa (Abaka, the name the Tuareg give to the region where the fossils were found). Afrovenator has been...

Allosaurus, meaning "different lizard", is a genus of theropod dinosaur from the Kimmeridgian/Tithonian age of the Late Jurassic Period (155 to 145 million years ago). It was first described in 1877 by Othniel Charles Marsh. The first recovered specimen came, most likely, from the Morrison Formation near Granby, Colorado. It was discovered in 1869 by Ferdinand Vandiveer Hayden. The original finding was identified by locals as "petrified horse hoofs". It was initially placed in the genus...

Ceratosaurus, meaning "horn lizard", is a genus of large predatory dinosaur from the Late Jurassic Period (Tithonian and Kimmeridgian ages). It is found in the Morrison Formation of North America, Tanzania and Portugal. It was discovered in the Cleveland Lloyd Dinosaur Quarry in central Utah and the Dry Mesa Quarry in Colorado. The type species, C. nasicornis, was described by O.C. Marsh in 1884 and then red scribed by Gilmore in 1920. Two more species, C. magnicornis and C. dentisulcatus,...
