Now: "Dreadnoughtus schrani"
Then: "Tyrannosaurus Rex"
Now: It stood two stories high at the shoulder. Its tail was almost as long as a city bus. And it tipped the scales at some 65 tons – heavier than a fully loaded semi-truck.
Meet Dreadnoughtus schrani, a newly discovered dinosaur and one of the most massive land animals of all time. And it's not just a heavyweight. Never before has anyone found so many representative pieces of a super-large dinosaur.
Hello, class, and welcome to Today In Frogs. Today's frog is called the Devil Frog, by scientists, for real. Above you will find an artist's rendering of it eating a dinosaur (?) (!).
The Devil Frog, Beelzebufo ampinga, lived about 70 million years ago in Gondwana (fossils are now found mostly in Madagascar). Back in 2008, some scientists decided it was the biggest frog that ever lived, the size of a "squashed beach ball," which apparently is about 16 inches long, and that it probably ate baby dinosaurs. An artist promptly drew that picture of a frog eating a dinosaur, thank you artist.
Is this the world's oldest dinosaur? Sure, why the hell not.
It's always funny to read about the discovery of "new dinosaurs." It's like when the original incarnation of Spinal Tap then called "The Originals" found out there was another band called "The Originals," and so they had to change their name to "The New Originals." (Which is a much better names, really.) Anyway, a new, or at least, heretofore undiscovered, type of dinosaur has indeed been found in Utah.
Scientists have named it Kosmocerotops. It's a close relative of the Triceratops, the famous rhinoceros-like plant-eater that has the big, armor-plated head with three horns. ("Cerotops" is Greek for "horned face.") But the Kosmocerotops, which lived around the Great [...]
Crack bit of paleontological detective work detailed in a new Nature article about Anomalocaris, a three-foot-long shrimp-like creature widely believed to have dominated the seas of the Paleozoic era's Cambrian period by "hunting and eating hard-shelled prey such as trilobites." In a recent computer-assisted analysis of fossilized Anomalocaris mouth parts, Amherst College's Whitey Hagadorn determined that the "Tyranosaurus rex of the Cambrian" lacked the chomping power to match its reputation. "Everyone shows it grabbing trilobites and munching them. Like a cookie monster," Hagadorn says. "Not possible." Hagadorn suggests Anomalocaris subsisted on a softer diet of jellyfish and worms, or maybe just filtered plankton. In turn, Hagedorn's colleagues insist [...]
