Dinosaur DNA clues unpicked by researchers at University of Kent

Dinosaur DNA clues unpicked by researchers at University of Kent

Science
British scientists say they have pieced together what dinosaur DNA looks like.Researchers at the University of Kent say their work uncovers the genetic secret behind why dinosaurs came in such a variety of shapes and sizes.This variation helped the creatures evolve quickly in response to a changing environment - helping them to dominate Earth for 180 million years.But the researchers behind the DNA work say they have no plans to recreate dinosaurs, Jurassic Park style.Of course, there was one final challenge the dinosaurs could not overcome - a massive asteroid impact 66 million years ago that wiped out all dinosaur groups except the flying ones that developed into birds.Recently, Prof Darren Griffin's team used mathematical techniques to identify the pos...
Coral reefs 'weathered dinosaur extinction'

Coral reefs 'weathered dinosaur extinction'

Science
Corals may have teamed up with the microscopic algae which live inside them as much as 160 million years ago, according to new research.The two organisms have a symbiotic relationship, meaning they need each other to survive.But this partnership was previously thought to have developed about 60 million years ago.The new findings suggest that reef algae may have weathered significant environmental changes over time.This includes the mass extinction that wiped out most of the dinosaurs.Algae's resilience to temperature changes has been of concern to scientists recently, as warming events on the Great Barrier Reef have seen the coral "bleached" of its algae. The study, conducted by an international ...
'Amazing Dragon' discovery in China turns the dinosaur world on its tail

'Amazing Dragon' discovery in China turns the dinosaur world on its tail

Technology
Paleontologists have discovered the fossils of a new species of dinosaur in northwestern China. The discovery of Lingwulong shenqi, shows there was an early member of the well-known group of plant-eating dinosaurs called sauropods -- early meaning 15 million years earlier than any previously-known member of the group. The newly-discovered dinosaur was a neosauropod, a group of long-necked vegetarians that includes brontosaurus and diplodocus. It is estimated to have been between 35 and 57 feet long from head to tail. The discovery was published in the British journal, Nature Communications on Tuesday. Lingwulong shengi translates to "Amazing Dragon from Lingwu". Lingwu, is the region where they were found; long is Mandarin for 'dragon' and shenqi is Mandarin for 'amazing'. Research...

New species of armoured dinosaur discovered

Technology
A fossil of a new species of armoured dinosaur has been discovered in Utah, changing how scientists believe the animals evolved. It took almost four years to prepare and analyse the medium-sized dinosaur's skeleton, which is 13-16ft long (4-5m) and about 42 inches (1.5m) tall at the hip, and one of the most complete ever discovered in this region of the US.Armoured dinosaurs, or ankylosauridae, existed exclusively in the northern hemisphere before they became extinct 66 million years ago. Image: A crew from the Natural History Museum of Utah excavated the dinosaur's bones. Pic: NHMU Fossils have been found in North America, East Asia and Europe, and the three regions have different forms of armour to differentiate...
Scientists publish 3D-printing plans for 200-million-year-old dinosaur skull

Scientists publish 3D-printing plans for 200-million-year-old dinosaur skull

Science
Jan. 12 (UPI) -- Anyone with access to a 3D printer can now create a replica of a 200-million-year-old dinosaur skull.Scientists at the University of the Witwatersrand in Johannesburg, South Africa, used advanced CT scanning technology to image and digitally reconstruct -- bone by bone -- a detailed 3D model of the skull of Massospondylus, a sauropodomorph dinosaur from the Early Jurassic.The researchers published their rendering of the ancient dino skull this week in the journal PeerJ."This means any researcher or member of the public can print their own Massospondylus skull at home," Kimi Chapelle, a PhD student at the Evolutionary Studies Institute at Wits, said in a news release.Massospondylus is one of the most famous dinosaurs in South Africa. Its fossil record is rich. But the lates...
