Dinosaurs Took A Middle Road Between Warm- And Cold-Blooded
2014-06-13 09:10:26

Lawrence LeBlond for redOrbit.com - Your Universe Online There has been a long-standing debate over dinosaurs: were they cold-blooded like modern day reptiles or warm-blooded like mammals? In the early days of science, and in Hollywood, these prehistoric beasts were depicted as slow, lumbering giants as they were believed to be cold-blooded. But over the past few decades, these animals have been portrayed as swift-moving lizards, more reminiscent of warm-blooded behaviors. New...

Gerard LeBlond for redOrbit.com - Your Universe Online Forests affected by fires 66 million years ago during the last days of the dinosaurs recovered no differently than they do today, according to a team of researchers from McGill University and the Royal Saskatchewan Museum. The team discovered the first fossil-record evidence of forest fire ecology during an expedition in southern Saskatchewan, Canada, at Grasslands National Park in an area known as the Frenchman Formation around...

Dinosaur Claws Were Used For More Than Just Ripping Flesh: Study
2014-05-07 12:08:20

Brett Smith for redOrbit.com - Your Universe Online The claws of Tyrannosaurus rex and Velociraptor are probably best known for ripping through the flesh of hapless prey, but a new study published in Proceedings of the Royal Society B has found that this family of dinosaurs, known as theropods, probably used its claws for a variety of purposes. In the study, Stephan Lautenschlager, from Bristol University, examined the differences in claw shape among theropods and analyzed them based...

Evolution Of Smaller Dinosaurs Helped Their Lineage Survive As Birds
2014-05-07 09:53:08

Brett Smith for redOrbit.com - Your Universe Online While dinosaurs may have disappeared from the face of the Earth, their lineage has survived in the form of birds and new research published in the journal PLOS Biology has found that both dinosaurs and birds evolved into smaller and smaller sizes – potentially contributing to their success. “Dinosaurs aren't extinct; there are about 10,000 species alive today in the form of birds,” said study author Roger Benson, a paleobiologist...

Revision To Rules To Decipher Color In Dinosaurs Suggests Connection Between Color And Physiology
2014-02-13 12:36:46

University of Texas at Austin New research that revises the rules allowing scientists to decipher color in dinosaurs may also provide a tool for understanding the evolutionary emergence of flight and changes in dinosaur physiology prior to its origin. In a survey comparing the hair, skin, fuzz and feathers of living terrestrial vertebrates and fossil specimens, a research team from The University of Texas at Austin, the University of Akron, the China University of Geosciences and four...

Steak-Knife Teeth First Appeared In Land Animals 300M Years Ago
2014-02-07 12:27:27

Lee Rannals for redOrbit.com - Your Universe Online A carnivorous dinosaur that roamed the Earth nearly 300 million years ago was the first terrestrial vertebrate to develop “steak-knife” teeth. The Dimetrodon was a dinosaur that walked on land between 298 million and 272 million years ago, and the latest study, published in Nature Communications, shows the ancient reptile wasn’t afraid to bite off more than it could chew. Researchers found that Dimetrodon was the first...

Giants Of Earth's History Still Pose A Wealth Of Riddles
2014-01-14 10:32:20

Johannes Gutenberg Universitaet Mainz Sauropods, the largest land animals in Earth's history, are still mightily puzzling the scientists. These plant-eating dinosaurs with their long necks and small heads could reach a height of 10 meters or more and dominated all other land vertebrates in terms of size. They could weigh up to 80 tons, more than any other known land vertebrate. One question that has been intensely debated is how these giants of the animal kingdom regulated their own body...

First Dinosaur Fossils In Saudi Arabia
2014-01-07 14:02:25

Lee Rannals for redOrbit.com - Your Universe Online "An international team of scientists have discovered the first record of dinosaurs in Saudi Arabia. Researchers from Uppsala University, Museum Victoria, Monash University and the Saudi Geological Survey said they discovered a string of vertebrae from the tail of a huge "Brontosaurus-like" dinosaur in the desert. Finding dinosaur fossils in the Arabian Peninsula is exceptionally rare, so the latest finding reported in the journal PLOS...

[ Watch the Video: Mummified Dino Fossil Had A Fleshy Head Crest ] redOrbit Staff & Wire Reports - Your Universe Online Researchers from Australia's University of New England (UNE) and Italy’s University of Bologna have reportedly discovered the first evidence that dinosaurs had fleshy head ornaments similar to a rooster’s comb. As the study authors report in Thursday’s edition of the journal Current Biology, they discovered the head crest on a rare, mummified specimen of...

Lizard Breath Developed Earlier Than Previously Thought
2013-12-12 05:05:45

redOrbit Staff & Wire Reports - Your Universe Online The one-way airflow breathing technique used by monitor lizards may have originated about 20 million years earlier than previously believed, according to a new paper appearing in Wednesday’s edition of the journal Nature. According to researchers from the University of Utah and Harvard University, air flows primarily in a one-way loop through the monitor lizard’s lungs. This breathing technique is believed to have been used by...

Robert Thomas Bakker (born March 24, 1945) is an American Paleontologist known for his contribution to the “Dinosaur Renaissance” and his support of his mentor Ostrom’s theory that some dinosaurs were warm-blooded. He specializes in the ecological context and behavior of dinosaurs. Bakker was born in Bergen County, New Jersey. As a young boy, he developed an interest in dinosaurs following his first trip to the dinosaur exhibit at the American Museum of Natural History – he was...

Paleontology
2014-01-12 00:00:00

Paleontology or Palaeontology is the scientific study of prehistoric life, including the study of fossils to determine the organisms evolution and interactions with each other and their environments. Paleontological observations have been documented as far back as 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and it developed quickly within the 19th century. The term itself comes from Greek palaios, meaning...

Paleozoology
2013-09-30 13:34:57

Paleozoology, also spelled Palaeozoology, is a branch of many other sciences including zoology and paleontology that focuses on recovering cellular matter from animal remains that are large enough to be seen without the help of a microscope, known as macrofossils. This study is primarily used in the context of archeology and geology and aids in recreating ancient ecosystems and prehistoric environments. Paleozoologists study the tissues of many types of animals including sharks, echinoderms,...

Zooarchaeology
2013-09-30 13:29:48

Zooarchaeology is the study of animal remains including shells, bones, hides, scales, DNA, chitin, and hair. Shells and bones are most frequently studied because these do not decay at a fast rate, but most remains do not survive because they break or decompose. In eastern areas of North America, Zooarchaeology developed over three periods. The first, known as the Formative period, occurred in the 1860s and was not a specific area of study at that time. The second period, known as the...

Seitaad, derived from a Navajo legend of a san monster with the same name -- "Seit'aad," is a genus of prosauropod dinosaur from the Early Jurassic Period. The type species, S. ruessi, was described in 2010 based on fossils recovered from the Navajo Sandstone Formation in southern Utah. It is known from a nearly complete fossil that appears to have been entombed by the collapse of a sand dune about 185 million years ago. Based on the fossil, the dinosaur would have been 10 to 15 feet long...

  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
