Hallucigenia sparsa
2014-08-19 03:00:38

University of Cambridge One of the most bizarre-looking fossils ever found - a worm-like creature with legs, spikes and a head difficult to distinguish from its tail – has found its place in the evolutionary Tree of Life, definitively linking it with a group of modern animals for the first time. The animal, known as Hallucigenia due to its otherworldly appearance, had been considered an ‘evolutionary misfit’ as it was not clear how it related to modern animal groups. Researchers...

paleontological reconstruction of rangeomorph fronds
2014-08-13 04:00:43

University of Cambridge New three-dimensional reconstructions show how some of the earliest animals on Earth developed, and provide some answers as to why they went extinct. A bizarre group of uniquely shaped organisms known as rangeomorphs may have been some of the earliest animals to appear on Earth, uniquely suited to ocean conditions 575 million years ago. A new model devised by researchers at the University of Cambridge has resolved many of the mysteries around the structure,...

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
2014-08-01 05:21:11

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...

Running For Life: How Speed Restricts Evolutionary Change Of The Vertebral Column
2014-07-15 03:30:37

Naturalis Biodiversity Center One of the riddles of mammal evolution explained: the strong conservation of the number of trunk vertebrae. Researchers of the Naturalis Biodiversity Center and the University of Utah show that this conservation is probably due to the essential role of speed and agility in survival of fast running mammals. They measured variation in vertebrae of 774 individual mammal skeletons of both fast and slow running species. The researchers found that a combination of...

reconstruction of the early Eocene

Gerard LeBlond for redOrbit.com - Your Universe Online The Silvacola acares is a tiny hedgehog species that lived roughly 52-million-years ago, during the Eocene Epoch. Its fossil remains were recently identified by a University of Colorado Boulder-led team working in British Columbia. Along with the tiny hedgehog, the fossils of a tapir-like animal were also discovered. A paper on the discovery of these two ancient mammals is being published today in the Journal of Vertebrate...

AGI The Society for Sedimentary Geology (SEPM) announces an unusual paper in their journal PALAIOS that combines ‘forensic’ paleontology and archeology to identify origins of the millstones commonly used in the 1800’s. While all millstones were used similarly, millstones quarried in France were more highly valued than similar stones quarried in Ohio, USA. Over four years the scientific team located millstones by visiting historical localities in Ohio, then studied them and...

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...

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...

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...

It can be found in northern areas of the Pacific Ocean with a range that extends from the coasts of China, Japan, and Siberia to the coasts of California in the United States. It prefers a habitat in rocky areas at depths of up to 1,380 feet. This species has two subspecies known as Solaster dawsoni dawsoni and Solaster dawsoni arcticus. It has a wide body with eight to thirteen...

Paleontology

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...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
