    Source: Geological Society of America Date: October 24, 2006 Far More Than A Meteor Killed Dinos, Evidence Suggests There's growing evidence that the dinosaurs and most their contemporaries were not wiped out by the famed Chicxulub meteor impact, according to a paleontologist who says multiple meteor impacts, massive volcanism in India, and climate changes culminated in the end of the Cretaceous Period. Cottonmouth Creek waterfall over the event deposit with reworked Chicxulub impact spherules. The original Chicxulub ejecta layer was discovered in a yellow clay layer 45 cm below the base of the event deposit. The yellow clay represents a...

BLOOMINGTON, Ind. -- Ancient rocks from the bottom of the Pacific Ocean suggest dramatic climate changes during the dinosaur-dominated Mesozoic Era, a time once thought to have been monotonously hot and humid. In this month's Geology, scientists from Indiana University Bloomington and the Royal Netherlands Institute for Sea Research present new evidence that ocean surface temperatures varied as much as 6 degrees Celsius (about 11 degrees Fahrenheit) during the...

    Dinosaur Soft Tissue Preserved by Blood? by Brian Thomas, M.S. * Researchers are now suggesting that iron embedded in blood proteins preserved the still-soft tissues, cells, and molecules discovered inside dinosaurs and other fossils after the creatures were buried in sediments. The ability to justify millions of years is at stake, and this study promises to do just that. What are its merits and demerits? Publishing in the journal Proceedings of the Royal Society B, Mary Schweitzer led a team that showed how iron atoms from blood adhere to and preserve blood vessels.1 The team placed ostrich bone blood vessels...
  • Baby Dinosaur Skeleton Unearthed in Canada

    The tiny, intact skeleton of a baby rhinoceroslike dinosaur has been unearthed in Canada. The toddler was just 3 years old and 5 feet (1.5 meters) long when it wandered into a river near Alberta, Canada, and drowned about 70 million years ago. The beast was so well-preserved that some of its skin left impressions in the nearby rock.

    Imagine watching an interview on television and hearing a bald, blind, deaf, wrinkled, hunched-back, bedridden man claim that he is 130 years old. Although you might doubt such a claim, if ever there was a man in modern times to live 130 years on Earth, he likely would have looked as worn out as this man appeared. Imagine, however, if a quick-witted, muscular, marathon runner with fair skin, thick, dark hair, low blood pressure, and a good memory, claimed to be 130 years old. What reasonable person would believe such a claim? Everyone would doubt the statement, especially the doctors,...

    EDMONTON - Experts are calling a dinosaur fossil unearthed in northern Alberta this week one of the “most complete finds in this part of the world in a long time.” Brian Brake, executive director of the Philip J. Currie Dinosaur Museum, said the fossilized remains of a hadrosaur were discovered at an energy company’s work site near Spirit River. Officials from the pipeline firm contacted the museum, which sent paleontologists to assess the find. “What we have is a totally composed tail,” Brake said. “It’s beautiful.” The Currie Museum contacted its counterparts at the Royal Tyrrell Museum in Drumheller, which...

    Was Tyrannosaurus rex a predator or scavenger? The question has been a point of controversy in the scientific community for more than a century. "You see 'Jurassic Park,' and you see T. rex as this massive hunter and killer, as incredibly vicious. But scientists have argued for 100 years that he was too big and too slow to hunt prey and that he was probably a scavenger, an animal that feeds only on dead things," University of Kansas paleontologist David Burnham said. Burnham and researcher Robert DePalma got what Burnham described as his "lucky break" when they found the fossil...

    July 17, 2013 — Rapid tooth replacement by sauropods, the largest dinosaurs in the fossil record, likely contributed to their evolutionary success, according to a research paper by Stony Brook University paleontologist Michael D'Emic, PhD, and colleagues. This is an illustration of a skull of Diploducus alongside the research team’s CT scan-generated images of some teeth in the front of its jaws. Bone is transparent and teeth are yellow. The arrows show the direction of tooth replacement, which is back to front similar to a shark.

    Scientist Stumped by Actual Dinosaur Skin by Brian Thomas, M.S. * Being the first ever to examine a dinosaur fossil long buried in sedimentary rock is thrilling enough for a field researcher. But a team working in Canada found an exhilarating bonus on a hadrosaur fossil fragment—it had actual skin still attached. They found the duck-bill dinosaur fossil near Grand Prairie, Alberta. University of Regina physicist Mauricio Barbi operates state-of-the art synchrotron equipment that can detect and identify chemical signatures without destroying samples. He plans to use the technology to investigate the special fossil and its skin. He told Canadian...

    The Utah reptiles belong to the horned-dinosaur family, which is known for outlandish anatomy, and are wowing seasoned fossil hunters. The species named Kosmoceratops had 15 horns decorating its massive head, giving it the most elaborate dinosaur headdress known to science. At 15 feet long, it was larger than a Ford Fiesta. Its name means "ornate horned-face" in Latin. The newly discovered dinosaurs, close relatives of the famous Triceratops, were announced today. Utah scientists believe most of the horns were used to attract mates and intimidate rivals of the same species. The dinosaur fossils were found in the Grand Staircase-Escalante...

    Fossil hunters have unearthed the remains of two new dinosaur species that roamed Utah's swamps 76 million years ago. Here's a brief guide to what exactly they found: What are the two new species? Kosmoceratops and Utahceratops, which have been classified (for obvious reasons) in the horned-dinosaur family which also includes the Triceratops. What did they look like? Kosmoceratops, whose hulking head sprouted 15 horns, was about 15 feet long, the size of a small car. Scott Sampson, the study leader at the Utah Museum of Natural History, calls it "one of the most amazing animals known." Utahceratops was 30...

    One of the best-known dinosaur species may not have really been a dinosaur species at all, according to new research. Scientists compared triceratops skulls to those of a lesser-known species, the torosaurus, and concluded that the triceratops were actually young torosauruses, New Scientist reports. They believe the three-horned dinosaur's skull changed shape as it aged. Researchers say the bones of the horns and neck frill in the young dinosaurs remained spongy until they became full adults. "Even in the most mature specimens that we've examined, there is evidence that the skull was still undergoing dramatic changes at the time of...

    Palaeontologists have identified the oldest known dinosaur embryos, belonging to a species that lived some 190 million years ago. The eggs of Massospondylus, containing well-perserved embryos, were unearthed in South Africa back in 1976. The creature appears to be an ancestor of the family that includes the long-necked dino once known as Brontosaurus. The study in the Journal of Vertebrate Paleontology also sheds light on the dinosaurs' early development.

    > The pterosaur's wingspan and size have spawned comparisons to dragons. But recently some scientists wondered whether the creature was too big to fly. A pair of papers recently asserted that the biggest pterosaurs may have been too heavy to get off the ground. That seemed implausible to Habib. After all, the biggest birds often have the longest flight range. And Quetzalcoatlus, with its 35-foot wingspan, certainly fits the bill for gigantic. So Habib teamed up with Mark Witton, a British paleontologist, to plug in factors like wingspan, weight and aerodynamics into a computer model. The results, which they presented...

    Mammals around the world exploded in size after the major extinction at the end of the Cretaceous period 65 million years ago, filling environmental niches left vacant by the loss of dinosaurs, according to a new study published today (Nov. 25) in the journal Science. The maximum size of mammals leveled off about 25 million years later, or 40 million years ago, because of external limits set by temperature and land area, reported an international team led by paleoecologist Felisa Smith of the University of New Mexico. "For the first 140 million years of their evolutionary history, mammals were basically...

    Crocodiles can no longer be referred to as "living fossils", according to scientists.Members of the crocodilian family have previously been thought to have changed little since prehistoric times. However, new fossil analyses suggests that modern crocodilians actually evolved from a very diverse group. Recently discovered ancient ancestors include small cat-like specimens, giant "supercrocs" and a pug-nosed vegetarian species. Body structureModern crocodilians are adapted to aquatic environments with long snouts, strong tails and powerful jaws. Yet contrary to popular belief, scientists now suggest that the basic body structure of crocodiles, alligators and ghariels evolved from a diverse group of prehistoric reptiles...
