No Single 'Missing Link' Found In Dinosaur-To-Bird Evolution Process

Chuck Bednar for redOrbit.com - Your Universe Online The early stages of the process through which birds evolved from dinosaurs was slow and gradual, and there was no single “missing link” separating the two different types of creatures,...

Chuck Bednar for redOrbit.com - Your Universe Online Originally believed to have occurred around the same time that mammals evolved some 200 million years ago, researchers from the Field Museum of Natural History in Chicago now report that the transition to nocturnal behavior actually occurred more than 100 million years earlier. Previous theories regarding nocturnal behavior were based on the large brains of mammals, which allow them to better process information from senses such as...

redOrbit Staff & Wire Reports - Your Universe Online A team of researchers led by Jahan Ramezani of MIT’s Department of Earth, Atmospheric and Planetary Sciences has discovered evidence that dinosaurs lived in North America millions of years earlier than previously suggested. Writing in the latest edition of the American Journal of Science, Ramezani and his colleagues state that precise dating of rocks which were found in the southern US and contained dinosaur fossils, suggest the...

April Flowers for redOrbit.com - Your Universe Online An international team of scientists has discovered what they believe to be the earliest example of social behavior in bird-hipped dinosaurs, along with a brand new species, in the Andes Mountains of Venezuela. The new species is described in the journal Proceedings of the Royal Society B: Biological Sciences. Until now, researchers have assumed this region was not home to dinosaurs because of the large deserts that surround it. The...

dinosaurs shrank to become birds

redOrbit Staff & Wire Reports - Your Universe Online The grand mystery over how massive, carnivorous dinosaurs gave rise to flying birds has a simple solution, as it turns out – the meat-eaters simply kept shrinking and shrinking over a period of 50 million years, according to research appearing in Friday’s edition of the journal Science. In their paper, an international team of scientists from the South Australian Museum, the University of Adelaide School of Earth and...

redOrbit Staff & Wire Reports - Your Universe Online Dinosaurs were victims of bad timing, and likely would have survived the asteroid impact that wiped them out had it occurred slightly earlier or later, researchers from Edinburgh University report in a new study. Dr. Steve Brusatte of the university’s School of GeoSciences and his colleagues explained that dinosaurs were at their most vulnerable when the asteroid hit, as a rising sea level and an increase in volcanic activity...

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...

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...
