Oldest Fossilized Shrimp in the world found!

Geologists study rare well-preserved creature showing muscles

Rodney Feldmann, professor emeritus, and Carrie Schweitzer, associate professor, from Kent State University’s Department of Geology report on the oldest fossil shrimp known to date in the world. The creature in stone is as much as 360 million years old and was found in Oklahoma. Even the muscles of the fossil are preserved.

Giant plankton-eating fishes roamed the prehistoric seas for over 100 million years before they were wiped out in the same event that killed off the dinosaurs, new fossil evidence has shown.

Dinosaur Extinction Grounded Ancient Birds, New Research Finds

Emus. New research suggests that ancestors of the African ostrich, Australasian emu plus cassowary, South American rheas and New Zealand moa became flightless independently, in close association with the extinction of the dinosaurs about 65 million years ago.

An abundance of food and lack of predators following the extinction of dinosaurs saw previously flighted birds fatten up and become flightless, according to new research from The Australian National University.

Schematic diagram to show how the mechanical advantage and active muscle volume in the dinosaur hind limb were reconstructed.

Were dinosaurs “warm-blooded” like present-day mammals and birds, or “cold-blooded” like present day lizards? The implications of this simple-sounding question go beyond deciding whether or not you’d snuggle up to a dinosaur on a cold winter’s evening.

Young tyrannosaurs did serious battle against each other.

We all know adolescents get testy from time to time. Thank goodness we don’t have young tyrannosaurs running around the neighborhood.

Crushed Bones Reveal Literal Dino Stomping Ground

The diagonal fracture in the ischium bone of a Venenosaurus suggests the break occurred when the bone was still fresh.

Imagine the gruesome sound of bones snapping as a thirsty, 30-ton dinosaur tramples a heap of fresh carcasses on his way to a rapidly shrinking lake.

That’s the scene revealed by a painstaking analysis of thousands of bones unearthed near Moab, Utah by geologists from Brigham Young University.

Map of major geological features and tracks at the Moyeni tracksite.

A new investigation of a fossilized tracksite in southern Africa shows how early dinosaurs made on-the-fly adjustments to their movements to cope with slippery and sloping terrain. Differences in how early dinosaurs made these adjustments provide insight into the later evolution of the group.

When pondering the demise of a famous dinosaur such as ‘Sue,’ the mighty Tyrannosaurus rex whose fossilized remains are a star attraction of the Field Museum in Chicago, it is hard to avoid the image of clashing Cretaceous titans engaged in bloody, mortal combat.

Tiny Tyrannosaur: T. Rex Body Plan Debuted In Raptorex, But 100th The Size

Tyrannosaurus_rex

Weighing as little as 1/100th that of its descendant T. rex, 125-million year old Raptorex shows off the distinctive body plan of this most dominant line of predatory dinosaurs.

A 9-foot dinosaur from northeastern China had evolved all the hallmark anatomical features of Tyrannosaurus rex at least 125 million years ago. Continue reading… “Tiny Tyrannosaur: T. Rex Body Plan Debuted In Raptorex, But 100th The Size”

What Do Dinosaurs And The Maya Have In Common?

The main pyramid at Mayapan.

One of the world’s most famous asteroid craters, the Chicxulub crater, has been the subject of research for about twenty years. The asteroid impact that formed it probably put an end to the dinosaurs and helped mammals to flourish. Together with an Anglo-American team, an ETH Zurich researcher has studied the most recent deposits that filled the crater. The results provide accurate dating of the limestones and a valuable basis for archaeologists to research the Maya.

Fossils of three new species of dinosaurs have been discovered in Australia

Fossils of three new species of dinosaurs have been discovered in Australia, including a meat-eater larger than Velociraptor from the Jurassic Park movies, suggesting Australia may have a more complex prehistoric past.
