2013-05-16 09:59:11

April Flowers for redOrbit.com - Your Universe Online New research into the incubation behavior of modern birds is shedding new light on the type of parental care carried out by their extinct ancestors. Geoff Birchard from the Department of Environmental Science and Policy at George Mason University, along with Charles Deeming and Marcello Ruta from the University of Lincoln's School of Life Sciences, wanted to test the theory that data from modern birds could be used to predict the...

Fossil Dinosaur Egg Reveals Uncommon Dinosaur Incubation Technique

Lee Rannals for redOrbit.com - Your Universe Online Researchers at the University of Calgary and Montana State University have found a small North American dinosaur that incubated its eggs in a way similar to some modern brooding birds. In a report of their findings that appeared recently in the journal Paleobiology, the scientists wrote about their close examination of the shells of fossil eggs found in Alberta and Montana from a small meat-eating dinosaur called Troodon. They said...

20 Dinosaurs Identified By Their Teeth
2013-01-25 19:33:35

Lee Rannals for redOrbit.com — Your Universe Online A few fossilized dinosaurs teeth have led researchers to help identify more than 20 species of small meat-eating dinosaurs. A University of Alberta researcher spent six years combing through collections of fossilized teeth in order to make the discovery. Derek Larson said he looked through thousands of dinosaur teeth found in western North America. “Derek was able to expand our identification of small, two-legged...

  A graduate student from Montana State University is part of a team of researchers that revealed a new species of raptorial dinosaur to the public on Monday, the first definitive troodontid theropod discovered from the Late Cretaceous Period of North America in more than 75 years. MSU doctoral student Mike Knell, MSU paleontologist David Varricchio, three colleagues, and lead researcher Lindsay Zanno, from the University of Wisconsin-Parkside and the Field Museum of Natural...

The discovery of a gruesome feeding frenzy that played out 73 million years ago in northwestern Alberta may also lead to the discovery of new dinosaur species in northwestern Alberta. University of Alberta student Tetsuto Miyashita and Frederico Fanti, a paleontology graduate student from Italy, made the discovery near Grande Prairie, 450 kilometers northwest of Edmonton. Miyashita and Fanti came across a nesting site and found the remains of baby, plant-eating dinosaurs and the teeth of a...

Canadian researchers have been given a unique look at dinosaur reproduction and the evolution of birds as they've narrowed down the likely owner of a dinosaur nest, abandoned on a river's edge 77 million years ago. The nest unearthed in northern Montana in the 1990s likely belonged to one of two types of small, carnivorous dinosaurs, according to scientists from the University of Calgary and Alberta's Royal Tyrrell Museum. The researchers believe it is either a ceanagnathid, which looks...

Troodon, meaning “wounding tooth,” is a genus of bird-like dinosaur from the Late Cretaceous Period (76 to 65 million years ago). Troodon was discovered in 1855 in North America and was one of the first dinosaurs found there. Fossils of this specimen have been found from Alaska to Wyoming, with possible Troodon fossils also being found in Texas and New Mexico. Troodon is known from the Judith River Formation and the upper Two Medicine Formation of Montana, the Judith River Group of...

Sinornithoides, meaning "Chinese bird form," is a genus of theropod dinosaur from the Barremian stage of the Early Cretaceous Period (130 to 125 million years ago). The type species, S. youngi, was described in 1993 by Dale Russell and Dong Zhiming based on a fossil found in the Ejinhoro Formation. It is known from a nearly complete specimen, missing only the roof of the skull and the cervical and dorsal vertebrae, along with a few other skeletal fragments. The holotype was preserved in a...

Zanabazar is a genus of troodontid dinosaur from the Late Cretaceous Period of Mongolia. Fossils from this creature have been found in the Nemegt Formation in Mongolia. Zanabazar was originally classified as a new species of the genus Saurornithoides by Rinchen Barsbold in 1974. A 2009 review of the genus found that there was little proof to back up this idea. The species was re-classified to its current genus Zanabazar -- named in honor of Zanabazar, the first spiritual head of Tibetan...

Jinfengopteryx, meaning "Golden phoenix feather", is a genus of maniraptoran dinosaur from the Early Cretaceous or Late Jurassic Period. It was found in the Qiaotou Formation of Hebei Province, China. The age of the specimen is uncertain as the formation where it was found underlies the more well-known Yixian Formation of the Early Cretaceous. Jinfengopteryx was preserved with extensive impressions of pennaceous* feathers, but lacked flight feathers on the hind legs, which are present in...
