Image 1 - Dinosaur Teeth Reveal Large Migrations
2011-10-27 07:06:52

An analysis of fossilized teeth from dinosaurs in the western United States has provided the first concrete evidence that sauropods undertook seasonal migrations in search of food. Scientists have often assumed that dinosaurs did, in fact, migrate.  However, it is difficult to determine from fossils even what dinosaurs looked like, let alone infer their behavior. But Henry Fricke, head of geology at Colorado College in Colorado Springs, and his colleagues seem to have found solid...

Image 1 - Land Animals Suffered Catastrophic Losses After Permian Period
2011-10-26 06:31:51

The cataclysmic events that marked the end of the Permian Period some 252 million years ago were a watershed moment in the history of life on Earth. As much as 90 percent of ocean organisms were extinguished, ushering in a new order of marine species, some of which we still see today. But while land dwellers certainly sustained major losses, the extent of extinction and the reshuffling afterward were less clear. In a paper published in the journal Proceedings of the Royal Society B,...

Large Tail Muscle Made Carnivorous Dinosaur Faster
2011-10-16 04:37:27

A massive tail muscle made a 23-foot-long carnivorous dinosaur one of the fastest-running (and deadliest) hunters of its era, a University of Alberta researcher has discovered. According to UPI reports on Friday, Scott Persons, a graduate student in paleontology at the university, used 3D computer models of re-create the tail muscles of the twin-horned Carnotaurus. Persons discovered that the dinosaur's tail had "a series of tall rib-like bones that interlocked with the next pair in...

Image 1 - Aquatic Beetle Found In 20-million-year-old Sediments
2011-10-06 08:46:47

The fossil beetle discovered in the 16-23 million years old sediments of the Irtysh River in southern Siberia belongs to the modern species Helophorus sibiricus, a member of the water scavenger beetles (Hydrophiloidea), which is at present widely distributed in Eurasia and reaches even North America. The species was originally described in 1860 by the Russian entomologist Victor Motschulsky based on specimens collected at Lake Baikal. It is aquatic and inhabits various kinds of standing...

Researchers Rebuild The Head Of An Armored Dinosaur
2011-09-29 09:50:15

[ Video 1 ]  |  [ Video 2 ] A University of Alberta-led research team has taken a rare look inside the skull of a dinosaur and come away with unprecedented details on the brain and nasal passages of the 72 million year old animal. Lead researcher Tetsuto Miyashita, a U of A master's student in paleontology, examined the armored skull of a Euoplocephalus, a six-meter long plant eater. The skull, which had been sitting in the U of A's paleontology collection, was broken,...

Image 1 - New Raptor Species Announced
2011-09-20 11:01:42

  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...

Image 1 - Study Finds 'Clear Evidence' Meteorite Wiped Out Primitive Birds
2011-09-20 06:10:58

  The same meteorite impact that caused dinosaurs to go extinct 65 million years ago also essentially wiped out ancient birds, a team of paleontologists claim in a new study. The researchers, led by Nicholas Longrich of Yale University, studied collections of approximately two dozen bird fossils of various species from the school's Peabody Museum of Natural History, as well as from the American Museum of Natural History, the University of California Museum of Paleontology, and the...

New Technique Fills In Fossil Record Gaps
2011-09-20 04:53:20

  University of Pennsylvania evolutionary biologists have resolved a long-standing paleontological problem by reconciling the fossil record of species diversity with modern DNA samples. Cataloging the diversity of life on earth is challenging enough, but when scientists attempt to draw a phylogeny – the branching family tree of a group of species over their evolutionary history – the challenge goes from merely difficult to potentially impossible. The fossil record is...

Beaver Have Experienced Little Change Over 7 Million Years
2011-09-19 10:01:11

  The fossilized teeth of a beaver found by Bureau of Land Management (BLM) employees on federal land represents the earliest record of the animal in North America and are estimated to be 7 to 7.3 million years old. The teeth come from the John Day Fossil Beds National Monument, a protected area with an abundance of fossils, Fox News is reporting. Surprisingly, the fossil teeth are almost identical to the chompers of living beavers and illustrate that the animal has changed little...

Image 1 - New Ancient Crocodile Named
2011-09-15 12:48:29

  Did an ancient crocodile relative give the world's largest snake a run for its money? In a new study appearing Sept. 15 in the journal Palaeontology, University of Florida researchers describe a new 20-foot extinct species discovered in the same Colombian coal mine with Titanoboa, the world's largest snake. The findings help scientists better understand the diversity of animals that occupied the oldest known rainforest ecosystem, which had higher temperatures than today, and could...

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
2013-11-14 11:54:31

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
2013-11-11 11:20:37

The morning sun star (Solaster dawsoni) is a species of starfish that is classified within the Solasteridae family. 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
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...
