Fossils of dicynodont exposed on each continent

Fossils discovered on a Tasmanian beach have established the survival in Australia of the dicynodont – an odd-looking species that lived 30 million years previous to the dinosaur – proving it existed on all continents.

The fossils were established by a pair strolling on a seaside on the Tasman Peninsula. The plant-eating animals, about the size of a cow, lived about 250 million years ago and became destroyed about 20 million years ago.

Complete specimens of the dicynodont have been establishing in India and South Africa. The detection of the two skull pieces found in Tasmania has enabled scientists to verify that the creature lived in Australia. The only other proof was a fossil found in Queensland in 1983.

A paleontologist of Queensland Museum, Dr Andrew Rozefelds said the "strange-looking beast” may have survived longer in Australia than on other continents.

Australia is an island continent and perhaps some things like the monotremes, like the platypus and the echidna, survived here as elsewhere in the earth they became extinct.

Small Four-Winged Dinosaur Sported Shimmery Black Feathers

A new fossil of a four-winged dinosaur concerning the dimensions of a pigeon shows he apparently sported quite the costume, complete with shiny black feathers and a tail tipped with a combine of ornamental streamer feathers.

The newly exposed fossil of Microraptor lived about 130 million years ago, through the early Cretaceous period, in what is nowadays northeastern China.

The researchers compared the agreement of these melanosomes with those of modern birds. When melanosomes are stacked tidily, the feather looks darker; when they are further muddled, the feather appears lighter.

From their analysis of modern birds, the researchers figured that this Microraptor fossil had black feathers. In addition, the narrow stacking of the melanosomes would have known the feathers iridescence.

The researchers couldn't be sure of the dye of the sheen, or the result of the iridescence on the quill color, because those factors depend on the width of the feather's keratin coat.

Collection of huge dinosaur bone found

The enormous scrape bone of a big meat-eating dinosaur has been exposed at Lightning Ridge, in the collection of the Australian Opal Centre.

One hundred million years ago at Lightning Ridge, a big dinosaur with hideous hand claws roamed the forests. This was a frightening huntsman that caught and slashed its quarry with claws like grappling hooks.

The bone is decomposed along one surface, but when absolute it would have been about 15 centimeters extended.

“We can recognize it by comparing it to extra scrape bones in the AOC set, and by referring to dinosaurs from elsewhere in Australia and overseas,” Elizabeth said.

The Carters Rush dinosaur was maybe four metres lengthy and up to three metres high at the trendy, same in size to Allosaurus from North America. This is the main theropod dinosaur ever exposed in NSW, and one of Australia’s biggest therapies.

Awesome Dino had comical Arms

With its blade-like teeth and frightening claws, Majungasaurus crenatissimus was one of the world’s most formidable predators, but new study reveals that it also obsessed some of the animal kingdom's negligible and most peculiar arms.

Tyrannosaurus rex and other well known greedy dinosaurs also had condensed forelimbs. While Majungasaurus, which lived 66 million years ago in Madagascar, was not a close T. rex family member, some lifestyle factors might have caused them to develop convinced similarities.

"The development of small arms in greedy dinosaur’s remains secrecy, but fossils like this is a significant sign in understanding the process,"

"Only by discovering the stops foremost from 'normal' longer arms in the family forms, to the short and strange ones in Majungasaurus and its close relatives, can we trust to clarify the evolutionary series and its causes."

The forearm skeletons are only a quarter of the length of the higher arm bones, but would have been broad and brawny. The wrist bones, however, aren't even ossified, and the short fingers probably lacked claws.
