This Dinosaur Wore Camouflage

A beautifully colored dinosaur fossil is the first to show evidence of countershading, a type of camouflage.

By

Surrounded by hungry predators, a little plant-eating dinosaur from the early Cretaceous did the only sensible thing. It donned camouflage.

Analysis of the exquisitely preserved fossil remains has revealed one of the most elaborate dinosaur paint jobs ever seen, including a brown back and a lighter belly. Modern-day antelope, fish and other animals have similar dark-and-light zones, which confuse predators, but this is the first discovery of such markings on a dinosaur.

“This one is unique,” says paleontologist Jakob Vinther of Britain’s University of Bristol, co-author of a study describing the fossil published in the journal Current Biology. “We can very clearly see that there are color patterns … stripes, spots.”

STOP MOTION DINOSAURS

The Alex Film Society will show The Lost World (1925) on Sunday, July 10th at 2:00 p.m. at the Alex Theatre in Glendale, CA.

The Lost World posterWhen Sir Arthur Conan Doyle was not writing Sherlock Holmes stories, he often wrote history, fantasy, adventure and science-fiction tales. One of his most successful novels was The Lost World, the story of adventurers who find a South American plateau – where time stopped 65 million years ago – inhabited by dinosaurs.

In 1912, when the book was published, movies were still in their infancy and technology wasn’t available to do the fantastic story justice, but by 1925, Willis O’Brien had begun to perfect stop motion, a form of animation that would allow him and his small team to bring these long dead creatures to life, blending them convincingly with real actors. It created a sensation when people saw, for the first time, believable prehistoric creatures on the screen, and remains a cinematic milestone today.

Featuring some of the biggest stars of the silent era, including Wallace Beery, Bessie Love and Lewis Stone, as well as no less than a dozen different species of dinosaur, our print of The Lost World is a fully restored version from the George Eastman House collection. Famed composer and pianist Alexander Rannie will accompany the film with the musical score that was written for the original release.

Newly Discovered Dinosaur Helps Explain Rise Of Tyrannosaurs

From: http://www.npr.org

Horse-sized primitive tyrannosaur Timurlengia euotica from the middle Cretaceous (ca. 90 million to 92 million years ago) of Uzbekistan.

Eighty million years ago, tyrannosaurs were the top predators in Asia and North America, and scientists say a newly discovered dinosaur from Uzbekistan helps to explain their rise.

In a paper published Monday in the Proceedings of the National Academy of Sciences, researchers said they have found a specimen from a 20 million-year gap in fossil records — between the small-bodied “marginal hunters” and the “apex predators” the tyrannosaurid group would become. This group includes Tyrannosaurus rex, Albertosaurus and Tarbosaurus.

baby-chasmosaurus-1024x494♦ Five-foot long skeleton proves to be a baby Chasmosaurus : In 2010, while looking for fossils along Alberta’s Red Deer River, paleontologists stumbled across part of a skull peeking out of the Cretaceous rock. Excavation revealed more and more bones, adding up to a nearly-complete skeleton, articulated and intact down to skin impressions on the ribs and the delicate ring of bones that were once encapsulated in the dinosaur’s eye. All cleaned up and now described by Phil Currie and colleagues, the dinosaur has turned out to be a baby Chasmosaurus – the smallest and most complete baby ceratopsid yet found.  READ MORE

♦ Scientists have discovered the fossilized remains of duck-billed dinosaur along a creek in Alabama, suggesting that this scaly behemoth emerged from what was then Appalachia before spreading out to other parts of the world. This new species, the first ever found in the eastern United States, was probably 20 to 30 feet long as an adult and lived during the late Cretaceous Period, roughly 83 million years ago.

♦ Tiny, delicate vessels that carried blood through a duck-billed dino-blood-vessels-151210dinosaur 80 million years ago never fossilized and still contain the beast’s tissue, a new study finds.  Researchers discovered the prize specimens on the femur (leg bone) of Brachylophosaurus canadensis, a 30-foot-long (9 meters) duck-billed dinosaur that was excavated in Montana in 2007. But it wasn’t immediately clear whether the blood vessels were made of organic matter originally from the dinosaur, or whether they had been contaminated over the years and were now made of bacteria or other components. Now, several tests show that the specimens are the original blood vessels, making them the oldest blood vessels on record to survive with their original components, the researchers said. READ MORE
