Dinosaur bones at Ogden park for cleaning, preserving

Pieces of a 75 million-year-old, plant-eating, duck-billed Dinosaur arrived at their temporary home at the George S. Eccles Dinosaur Park last week.

The Fossils came from the Grand Staircase-Escalante National Monument and will stay in Ogden until they have been cleaned and well preserved. After that, they'll end up in the Utah Museum of Natural History in Salt Lake City as a latest exhibit.

Gigantic pieces of fossil, still encased in rocks, were wrapped in burlap and plaster before being lifted by helicopter out of their remote desert home. The packages can weigh more than thousand pounds.

The bones arriving in Ogden are generally from the animal's arms, said Mike Getty, University of Utah UMNH collection manager of paleontology.

Other pieces of bone have been extracted and cleaned by different teams in the state, but these came to Ogden because the dedicated team of volunteers would be able to clean and set up them by August, in time to be mounted for exhibition, said Alan Titus, Monument paleontologist.

Tiny dinos died after falling into 160-mln-yr-old deep footprints of larger beasts

The exceptional Fossil haul of feathered dinosaurs in a 160-million-year-old marsh in China proposes that they perished after falling into the deep muddy footprints of larger beasts.

According to a report in New Scientist, David Eberth of the Royal Tyrrell Museum in Drumheller, Alberta, Canada, established partial skeletons of 18 small two-legged Dinosaurs in the 160-million-year-old sediments.

They were stacked on top of each other, apparently after becoming trapped about circular swampy pits.

The pits enclose distinctive red fragments of crust mixed into the mud.

The palaeontologists reckon this is the effect of large, heavy sauropod feet breaking through a crusty surface layer to watery mud beneath.

A thin crust would have formed hiding the trap from an unsuspecting tiny dinosaur but unable support its weight.

The thin crust would have buried the trap from an unsuspecting small dinosaur.

Fifteen of the fossils were Limusaurus inextricabilis, an odd bipedal dinosaur with tiny arms and a beak.

Even though it belonged to a group of predators it appears to have eaten plants.

"The victims were less than 1 meter tall and 1 to 3 meters long, so they would have been too short to drive against the bottom, which was 1 or 2 meters beneath the surface of the watery mud," said Eberth.

Their arms would have been enveloped with mud-slicked feathers and too small to pull them out of the hole.

"Finding any fossil remains like these, whose presence depends on the activities of other dinosaurs is bizarre." Eberth said.

Dinosaurs on steroids: The Copenhagen conclusion

The global financial disaster and the threats of climate change are symptoms of the same cause.

That cause is the dinosaur-like structure of economies that grew out of the Industrial Revolution and evaded the cost of fixing heavy pollution of smokestack industries by exporting them around the globe to others keen to get rich too.
The mirrors and smoke model that makes money and pretends waste disappears has now turned full circle, and come up against itself at the Copenhagen climate change conference.
The enduring meeting of 192 parties will be the first time all nations, side-by-side, have had to face the truth that there is nowhere left to pollute - and nowhere else to borrow from.

Until now science has seemed esoteric compared to the pragmatism and rationality of the market. Every time a new disaster occurred, the same mantra was chanted: "markets will adjust".

Well, the markets adjusted dreadfully in September last year, and economists' solution for the US is to print 8 billion $100-paper bills.
Climate change can be a more disastrous market adjustment. Catastrophic geographic situations cannot be papered over with money. That financial accounting has become unhinged from the real economy is already obvious

New Evidence Suggests An Asteroid Couldn't Have Killed The Dinosaurs

Princeton geoscientist Gerta Keller has new proof to support her alternative theory that volcanoes, not meteorites, wiped out the dinosaurs. Indeed, the evidence is so convincing that we might be dropping the whole "alternative" part.

Keller is one of several co-authors on a new paper in The Journal of the Geological Society of London that lays out the startling innovative evidence. prior studies of rock formations in India, Mexico, and the United States had first prompted Keller to conclude there was a discernible period between the massive meteorite impact that has been advanced as the killer of the dinosaurs, and their actual final extinction.

This extinction, which is known to have occurred 65 million years back, marked one of the most drastic biological upheavals this planet has ever seen. Signaling the last part of the age of reptiles (the Mesozoic Era) and the beginning of the age of mammals (the Cenozoic Era), this limit between the Cretaceous (abbreviated "K") and Tertiary ("T") periods is known in scientific literature as the K-T Boundary. The K-T Boundary can be observed geologically through the vastly different plant and animal species found on each side of the divide.
