This group gets some pretty cool art posted to it. The kind of superb stuff that graced the books of my youth, assuring a never ending love of ancient life.

A new smaller breed of the world’s best known dinosaur is thought to have once roamed the Arctic.

Dating back 70 million years, this new pygmy tyrannosaur is smaller but otherwise extremely similar to its larger sub-tropic counterpart. Palaeontologists had initially believed that a specimen unearthed in 2006 was simply a juvenile until further research later revealed that it was in fact a fully matured adult of a different species.

While the regular Tyrannosaurus rex can grow up to 40ft in length and weigh 4 tons, this new smaller species, known as Nanuqsaurus hoglundi, measures only 25ft and weighs 1,000lbs.

“The ‘pygmy tyrannosaur’ alone is really cool because it tells us something about what the environment was like in the ancient Arctic,” said study co-author Anthony Fiorillo.

“But what makes this discovery even more exciting is that Nanuqsaurus hoglundi also tells us about the biological richness of the ancient polar world during a time when the Earth was very warm compared to today.”

Ah, the stuff we don’t know… I like it.

Also digging the fact that this fella lived in the Arctic. Can you imagine how warm the Earth was back then? Gosh, think of the Equator! WhooHoo!

I often wonder what it’d be like to venture back to those days in a Tardis… I think I would love it… but at the same time there’s always the nagging fear of opening the door only to greet a 9-foot eurypterid or something… and being dinner is, um, not good!

Peace.

Hey, an exciting pushback of dogmatic dates has occurred, dinosaur fossils having been discovered in China that sport fuzzy, bristly “proto-feathers” in select areas at a much earlier time than thought. The BBC report excerpt is below… it conjures up some fascinating scenes of what could have been.

The critters in this image from the science journal Nature look pretty good with a mane on, don’t you think? Makes you want to hop into a Tardis, it does me at least, even with my strong trepidation regarding opening the door to a 3 meter long Eurypterid. Really. That wouldn’t be good. They’re slightly more dangerous than the ones that Saudi dude ate

Fossil hints at fuzzy dinosaurs

A discovery in China has prompted researchers to question the scaly image of dinosaurs.

Previously, experts thought the first feathered dinosaurs appeared about 150 million years ago, but the find suggests feathers evolved much earlier.

This has raised the question of whether many more of the creatures may have been covered with similar bristles, or “dino-fuzz”.

The team describe the fossil in the journal Nature.

Hai-Lu You, a researcher from the Insitute of Geology in Beijing, was part of the team that discovered the fossil.

He told BBC News he was “very excited” when he realised the significance of what his team had found.

He described the filaments seen on the body of the new dinosaur, which the team has named Tianyulong confuciusi, as “protofeathers” – the precursors of modern feathers.

“Their function was probably display, as well as to keep the body warm” he said.

Dr You’s team noticed that the filaments on the base of their dinosaur’s tail were extremely long.

These, they suggest, might have evolved for show, and may even have been coloured.

“The world of dinosaurs would [have been] more colourful and active than we previously imagined,” he said.
