Early Evolution Linked To Climate Change And Oxygen Levels
2012-09-28 11:50:55

April Flowers for redOrbit.com - Your Universe Online Geochemists from the University of California, Riverside teamed up with an international team of scientists to uncover new evidence linking together extreme climate change, elevation of oxygen levels and early animal evolution. Scientists have long speculated that a dramatic rise in atmospheric oxygen levels was the trigger for early animal evolution. The direct cause-and-effect relationships between environmental and animal...

multiplacophoran reconstruction
2012-09-20 10:30:45

Brett Smith for redOrbit.com - Your Universe Online Using computer animation, CT scanning and 3-D printing technology, a team led by University of Texas at Austin paleontologist Jakob Vinther has reconstructed an ancient mollusk that inhabited the waters around modern day Ohio about 390 million years ago. Until now, only a few partial fossils of the creature, known as a multiplacophoran, existed and the new model allows paleontologists to study the physiology of the specimen in greater...

John Neumann for redOrbit.com — Your Universe Online America has seen its share of wars, but did you hear about the Bone Wars? The late 1800s found archeologists digging furiously throughout the newly settled American west in a mad dash to find fossils. This lead to fighting in academic circles, and occasionally in the field itself, over disputes that became known as the Bone Wars. Leading the search in western Texas were geologist Robert T. Hill, now acclaimed as the Father of...

Dinosaur Art: A Feast For The Mind, Senses, And Imagination
2012-09-03 05:15:28

April Flowers for redOrbit.com - Your Universe Online Although almost every college or university has an Arts and Sciences department, combining everything from theater and studio art to biology and geology under one roof, most of us consider these two disciplines as being not only separate but polar opposites. Artists are freethinking, creative creatures who entertain and amaze us with what never was and never could be. They create illusions. Scientists are solid, empirical thinkers...

How The Mollusc Got Its Teeth Revealed By Ancient Fossils
2012-08-22 15:06:06

The radula sounds like something from a horror movie — a conveyor belt lined with hundreds of rows of interlocking teeth. In fact, radulas are found in the mouths of most molluscs, from the giant squid to the garden snail. Now, a "prototype" radula found in 500-million-year-old fossils studied by University of Toronto graduate student Martin Smith, shows that the earliest radula was not a flesh-rasping terror, but a tool for humbly scooping food from the muddy sea floor. The Cambrian...

Dinosaur Footprint Found At NASA
2012-08-22 04:57:38

Video: Cretaceous Footprint Found on Goddard Campus Michael Harper for redOrbit.com — Your Universe Online This summer, a dinosaur tracker had discovered a large dino footprint from a prehistoric armored animal in Greenbelt, Maryland. Ray Stanford has been tracking these dino footprints for years, and says he believes this specific footprint belongs to the Nodosaur, a beast which could have left the track as many as 112 million years ago. This latest discovery is one of...

50 Years After The Leakeys, Dawn Of Humanity Illuminated In Special Journal Edition
2012-08-21 10:16:51

Wits' scientists are part of the most comprehensive research to come out of Olduvai in East Africa since the early 1980s The first systematic, multidisciplinary results to come out of research conducted on the edge of the Serengeti at the rich palaeoanthropological site in the Olduvai Gorge in Tanzania since that produced by Louis and Mary Leakey's team, have recently been published in a special issue of the prestigious Journal of Human Evolution. Professor Marion Bamford, deputy...

What Triggered North American Dinosaur Diversity?
2012-08-04 07:09:39

redOrbit Staff & Wire Reports - Your Universe Online The rise of the Rocky Mountains and the arrival of a seaway that divided North America into three distinct sections may have been the catalyst for the evolution of new species of dinosaurs, claims a new study published in Thursday's edition of the journal PLoS ONE. The study, which was led by Ohio University (OU) postdoctoral researcher Terry Gates, could explain evolutionary and migratory patterns of North American duck-billed...

Human Evolution, Neanderthals And Interbreeding
2012-07-28 06:49:58

Brett Smith for redOrbit.com - Your Universe Online A recent genetics study has shown evidence that another branch of the human evolutionary tree may have existed alongside Neanderthals, fueling the ongoing feud between paleontologists and geneticists. According to the study published this week in the journal Cell, a team of geneticists led by Joseph Lachance and Sarah A. Tishkoff of the University of Pennsylvania found DNA evidence of an interbreeding with an unknown archaic species of...

Sea Star Evolution
2012-07-26 14:08:55

How quickly can new species arise? In as little as 6,000 years, according to a study of Australian sea stars. "That's unbelievably fast compared to most organisms," said Rick Grosberg, professor of evolution and ecology at UC Davis and coauthor on the paper published July 18 in the journal Proceedings of the Royal Society B. Grosberg is interested in how new species arise in the ocean. On land, groups of plants and animals can be physically isolated by mountains or rivers and then...

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...

Northern Sun Star, Solaster endeca

The northern sun star (Solaster endeca), also known as the purple sun star or the smooth sun star, is a species of starfish that is classified within the Solasteridae family. It can be found in the North Sea and the Atlantic Ocean with a range that includes coastlines of Greenland, Canada, and the United States. It prefers a habitat in areas with adequate to heavy shelter and muddy or rocky sediment, at depths of up to 1,480 feet. The northern sun star is large, reaching a diameter of 7.9...

Morning Sun Star, Solaster dawsoni

It has a wide body with eight to thirteen...

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...

John R. “Jack” Horner (born June 15, 1946) is an American paleontologist known for his research on dinosaur growth, and for discovering evidence that some dinosaurs nested and cared for their young.  He is perhaps the most famous paleontologist due to his role as technical advisor for all three Jurassic Park films, and his providing inspiration for Dr. Alan Grant, the film's lead character. He also advised on the FOX television show Terra Nova. Horner was born and raised in the small...
