    Oviraptor tails were also extremely muscular, and, according to fossil impressions, had a fan of feathers at the end. In Persons’ view, oviraptors could very well have used their muscular, flexible tails to wave their feathers in order to impress potential mates, just as peacocks use their magnificent jewel-toned feathers in courtship displays today.

    Dinosaurs Ate Rice by Brian Thomas, M.S. | Nov. 4, 2011 Just what did dinosaurs eat? One way researchers are finding out is by studying coprolites, or fossilized dinosaur dung. And as it turns out, some dinosaurs ate rice plants. But if flowering plants like rice did not evolve until millions of years after dinosaurs lived—as evolution maintains—how could dinosaurs have eaten them? Some coprolites contain phytoliths, which are uniquely shaped microscopic crystals manufactured by various plant tissues. Most phytoliths are made of silicon dioxide, the same chemical that comprises sand. Scientists examining these tiny grains can often discern from...

    I read that carbon dating method is only accurate for up to 30,000 yrs. So how are scientists coming up with millions yrs. old fossils? For all we know dinosaurs died off not millions but 100's of thousands of yrs ago.

    Dinosaur fossils don't come much more impressive than this. With 98 per cent of its skeleton preserved, this young predatory theropod from southern Germany may be the most complete dinosaur ever found. Oliver Rauhut, curator of the Bavarian State Collection for Palaeontology and Geology in Munich, announced the find yesterday. Although Chinese bird and dinosaur fossils are famed for delicate details such as their feathers, they don't match this 72-centimetre-long theropod in terms of clarity and completeness of preservation. The young dinosaur has been dated at 135 million years old, putting it in the early Cretaceous, but it has yet...

    Boulder, CO, USA - Long before whales, the oceans of Earth were roamed by a very different kind of air-breathing leviathan. Snaggle-toothed ichthyosaurs larger than school buses swam at the top of the Triassic Period ocean food chain, or so it seemed before Mount Holyoke College paleontologist Mark McMenamin took a look at some of their remains in Nevada. Now he thinks there was an even larger and more cunning sea monster that preyed on ichthyosaurs: a kraken of such mythological proportions it would have sent Captain Nemo running for dry land. McMenamin will be presenting the results of his...

    Yeah, Herman Cain won the Florida straw poll, crushing Mitt Romney and Rick Perry. And OK, a CBS poll recently found him tied with Romney among likely Republican primary voters. Sure, he also scored a resounding victory in another straw poll this weekend. And Rasmussen just today released the finding that 56% of GOP voters like Cain's 9-9-9 plan. So is that enough to make the Associated Press consider Cain a first-tier candidate? Nah. On MSNBC's "Daily Rundown" this morning, AP's political editor, Liz Sidoti, sniffed "we still consider him a second-tier candidate." View the video here.

    Fluffy structures trapped in thumbnail-sized bits of ancient amber may represent some of the earliest evolutionary experiments leading to feathers, according to a new study. These filaments of "dinofuzz" are so well preserved that they even provide hints of color, the researchers say. The oldest bird, Archaeopteryx, lived in what is now Germany about 150 million years ago, and the oldest known feathered dinosaur, Anchiornis huxleyi, lived in northeastern China between 151 million and 161 million years ago. Both creatures had modern-style feathers, each of which had a central shaft; barbs, which made up the feather's vane; and substructures called...

    Fossil of the baby nodosaur. No, this isn't Jurassic Park. Researchers at the Johns Hopkins University School of Medicine with help from an amateur fossil hunter in College Park, Md., have described the fossil of an armored dinosaur hatchling. It is the youngest nodosaur ever discovered, and a founder of a new genus and species that lived approximately 110 million years ago during the Early Cretaceous Era. Nodosaurs have been found in diverse locations worldwide, but they've rarely been found in the United States. The findings are published in the September 9 issue of the Journal of Paleontology.

    Stephen Spielberg has remade "Jurrasic Park" for TV. It starts in September. It is described as a tree-hugger version of a time-travel story (Earth's atmosphere becomes so polluted that people have to flee back in time 85 million years.) An updated Robinson family (per "Lost in Space") is described as the main characters. The trailers look like outtakes from "Jurrasic Park." My question: does this thing have a chance at "something over $4M" per episode?

    Dinosaur Breath The largest flying creature alive today is the Andean condor Vultur gryphus. At maximum size it weighs about 22 pounds and has a wingspread of about 10 feet. But 65 million years ago in the late cretaceous period, the last age of dinosaurs, there was another larger flying animal, the giant pterosaur Quetzalcotalus. It had a wingspread of over 40 feet, the size of a small airplane. Other pterosaurs were also quite large. The pteranodons of the late jurassic period, the classic flying dinosaurs of magazine illustrations, had a maximum wingspan of about 33 feet. This presents a...

    Dino-Era Feathers Found Encased in Amber James Owen for National Geographic NewsMarch 11, 2008 Seven dino-era feathers found perfectly preserved in amber in western France highlight a crucial stage in feather evolution, scientists report. The hundred-million-year-old plumage has features of both feather-like fibers found with some two-legged dinosaurs known as theropods and of modern bird feathers, the researchers said. This means the fossils could fill a key gap in the puzzle of how dinosaurs gave rise to birds, according to a team led by Vincent Perrichot of the Museum für Naturkunde-Berlin in Germany. The find provides a clear example "of...

    Dog-sized dinosaurs that lived near the South Pole, sometimes in the dark for months at a time, had bone tissue very similar to dinosaurs that lived everywhere on the planet, according to a doctoral candidate at Montana State University. That surprising fact falsifies a 13-year-old study and may help explain why dinosaurs were able to dominate the planet for 160 million years, said Holly Woodward, MSU graduate student in the Department of Earth Sciences and co-author of a paper published Aug. 3 in the journal PLoS ONE. "If we were trying to find evidence of dinosaurs doing something much different...

    An enormous jawbone found in Kazakhstan is further evidence that giant birds roamed - or flew above - the Earth at the same time as the dinosaurs. Writing in Biology Letters, researchers say the new species, Samrukia nessovi, had a skull some 30cm long. If flightless, the bird would have been 2-3m tall; if it flew, it may have had a wingspan of 4m. The find is only the second bird of such a size in the Cretaceous geologic period, and the first in Asia. The only other evidence of a bird of such a size during the period was...

    A 200 million year old reptilian fossil was discovered by Alaskan scientists along the shores of Tongass National Forest. It was the low tide that made the discovery possible as a rare marine creature called Thalattosaurs was submerged in water and rocks. The last Thalattosaurs to survive was after the Triassic period, roughly 200 million years ago. An almost complete skeleton was recovered along with an outline of the body embedded onto surrounding rocks. The creature is usually between 3 to 10 feet long with padded limbs and flat tails. The snout turns downward and contains both pointy teeth for...

    One of the world's most famous fossil creatures, widely considered the earliest known bird, is getting a rude present on the 150th birthday of its discovery: A new analysis suggests it isn't a bird at all. Chinese scientists are proposing a change to the evolutionary family tree that boots Archaeopteryx off the "bird" branch and onto a closely related branch of birdlike dinosaurs. Archaeopteryx (ahr-kee-AHP'-teh-rihx) was a crow-sized creature that lived about 150 million years ago. It had wings and feathers, but also quite un-birdlike traits like teeth and a bony tail. Discovered in 1861 in Germany, two years after...

    A fossil discovered in Montana has given new momentum to the hypothesis that dinosaurs were thriving right up until a devastating meteor hit Earth 65 million years ago, causing their extinction. Scientists from Yale University have found what is believed to be the youngest dinosaur fossil ever found, thought to be from just before the mass extinction took place. The discovery, described in a study published in the online edition of the journal Biology Letters, contradicts the theory that the dinosaurs slowly went extinct before the cosmic impact. The fossil -- a 45-centimetre horn believed to be from a triceratops...

    New Haven, Conn.—A team of scientists has discovered the youngest dinosaur preserved in the fossil record before the catastrophic meteor impact 65 million years ago. The finding indicates that dinosaurs did not go extinct prior to the impact and provides further evidence as to whether the impact was in fact the cause of their extinction. Researchers from Yale University discovered the fossilized horn of a ceratopsian – likely a Triceratops, which are common to the area – in the Hell Creek formation in Montana last year. They found the fossil buried just five inches below the K-T boundary, the geological...

    A skull belonging to one of the largest "sea monsters" ever unearthed is being unveiled to the public. The beast, which is called a pliosaur, has been described as the most fearsome predator the Earth has seen. The fossil was found in Dorset, but it has taken 18 months to remove the skull from its rocky casing, revealing the monster in remarkable detail. Scientists suspect the creature, which is on show at the Dorset County Museum, may be a new species or even genus. ~~~snip~~~ "It was probably the most fearsome predator that ever lived.

    Pterosaurs, flying reptiles from the time of the dinosaurs, were not driven to extinction by the birds, but in fact they continued to diversify and innovate for millions of years afterwards.A new study by Katy Prentice, done as part of her undergraduate degree (MSci in Palaeontology and Evolution) at the University of Bristol, shows that the pterosaurs evolved in a most unusual way, becoming more and more specialised through their 160 million years on Earth. The work is published today in the Journal of Systematic Palaeontology. ‘Usually, when a new group of animals or plants evolves, they quickly try out...

    If you see a seven-foot lizard in your Broward or Palm Beach residence, that's a problem, according to the Florida Fish and Wildlife Conservation Commission. Nile Monitor lizards, native to Africa, have been popping up around the two counties -- enough times to warrant a hotline and a website dedicated to reporting freak lizard sightings. The lizard hot spot is the canal along Southern Boulevard in West Palm Beach, according to the FWC, which just caught two in the area last week -- including a five-foot lizard discovered on someone's patio after it crawled through the doggy door. They killed...
