Asteroids keep falling on my head…

Asteroids keep falling on my head… but that doesn’t mean my eyes will soon be turnin’ red…I’m never gonna stop them by complainin’…

We will eventually have our latest MonSFFA project, the stop-motion animation: Theories of Dinosaur Extinction available on line, but while we wait for Cathy & Keith to get their act together, here are solutions for preventing human extinction.

Serikornis sungei had 4 wings but couldn’t fly

From National Geographic’s web page:

http://news.nationalgeographic.com/2017/08/feathered-dinosaur-four-wings-species-serikornis-science/?

A pheasant-size dinosaur found in China is causing a stir among scientists trying to understand the origins of flight.

The newly named species, Serikornis sungei, adds to the ranks of dinosaurs that effectively had four wings, thanks to heavily feathered hindlimbs and forelimbs. But in a twist for paleontologists, the evidence suggests that Serikornis couldn’t fly.

“The feathering of Serikornis shows for the first time a complete absence of barbules—that is, the microstructures that allow feathers to resist air pressure during wing beats,” says study leader Ulysse Lefèvre, a paleontologist at the Royal Belgian Institute of Natural Sciences in Brussels.

Ichthyosaurus fossil is ‘largest on record’

The fossil of a marine reptile ”re-discovered” in a museum is the largest of its kind on record, say scientists.

The ”sea dragon” belongs to a group that swam the world’s oceans 200 million years ago, while dinosaurs walked the land.

The specimen is the largest Ichthyosaurus to be described, at more than three metres long.

It was discovered on the coast of England more than 20 years ago, but has remained unstudied until now.

Palaeontologist Sven Sachs saw the fossil on display at a museum in Hannover. He contacted UK palaeontologist, Dean Lomax, who is an expert on Ichthyosaurs….

…The reptile was an adult female that was pregnant at the time of death.

”This specimen provides new insights into the size range of the species, but also records only the third example of an Ichthyosaurus known with an embryo,” added Dean Lomax. ”That’s special.’

New Dinosaur Species

It’s Official: Stunning Fossil Is a New Dinosaur Species

 A new study of the fossil also makes the controversial claim that the armored dinosaur had anti-predator camouflage.

About 110 million years ago in what’s now Alberta, Canada, a dinosaur resembling a 2,800-pound pineapple ended up dead in a river.

 

 

 

Today, that dinosaur is one of the best fossils of its kind ever found—and now, it has a name: Borealopelta markmitchelli, a plant-eating, armored dinosaur called a nodosaur that lived during the Cretaceous period. After death, its carcass ended up back-first on the muddy floor of an ancient seaway, where its front half was preserved in 3-D with extraordinary detail.

Unearthed by accident in 2011 and unveiled at Alberta’s Royal Tyrrell Museum in May, the fossil immediately offered the world an unprecedented glimpse into the anatomy and life of armored dinosaurs.

“It’s a beautiful specimen,” says Victoria Arbour, a postdoctoral researcher at the Royal Ontario Museum who is studying another well-preserved armored dinosaur called Zuul crurivastator. “It’s great to have specimens like this one and Zuul that give us an idea of what these dinosaurs looked like when they were alive.”

In addition to announcing its name, the first scientific description of the nodosaur, published today in the journal Current Biology, is revealing even more of its secrets.

“We knew six years ago that this was going to be special,” says Don Henderson, the Royal Tyrrell Museum’s curator of dinosaurs. “I don’t think we realized how special it was.”

‘Frankenstein dinosaur’ mystery solved

‘Frankenstein dinosaur’ mystery solved

16 August 2017From the section Science & Environment 

Scientists have solved the puzzle of the so-called “Frankenstein dinosaur”, which seems to consist of body parts from unrelated species.

A new study suggests that it is in fact the missing link between plant-eating dinosaurs, such as Stegosaurus, and carnivorous dinosaurs, like T. rex.

The finding provides fresh insight on the evolution of the group of dinos known as the ornithischians.

The study is published in the Royal Society journal Biology Letters.

Cambridge University’s Matt Baron tells Today that the new dinosaur fills a family tree gap To listen to audio file, or view the revised family tree, click here.

Matthew Baron, a PhD student at Cambridge University, told BBC News that his assessment indicated that the Frankenstein dinosaur was one of the very first ornithischians, a group that included familiar beasts such as the horned Triceratops, and Stegosaurus which sported an array of bony plates along its back.

“We had absolutely no idea how the ornithischian body plan started to develop because they look so different to all the other dinosaurs. They have so many unusual features,” the Cambridge scientist said.

“In the 130 years since the ornithischian group was first recognised, we have never had any concept of how the first ones could have looked until now.”

The Frankenstein dinosaur, more properly called Chilesaurus, puzzled experts when it was first discovered two years ago.

It had the legs of an animal like a Brontosaurus, the hips of a Stegosaurus, and the arms and body of an animal like Tyrannosaurus rex. Scientists simply did not know where it fitted in the dino family tree.

In the currently accepted family tree, the ornithischian group was always thought to be completely unrelated to all of the other dinosaurs.

Palaeontologists regarded these creatures as an odd-ball group. But a reassessment by Mr Baron published in March in the journal Nature indicated that ornithischians were more closely related to the meat-eaters, such as T.rex, than previously thought.

And it is in re-configuring the dinosaur family tree that Mr Baron transforms the Frankenstein dinosaur from an enigma into a missing link.

“Now that we think ornithischians and meat-eating dinosaurs such as Tyrannosaurus are related, Chilesaurus slots exactly in between the two groups. It is a perfect half-and-half mix. So, suddenly in the new tree it makes a whole lot of sense.”

Feathered Dinosaur Fossil

Chinese construction workers excavating bedrock recently made an explosive discovery when they inadvertently unearthed an unusual new species of feathered dinosaur.

The animal lived about 66 to 72 million years ago, right before a giant impact wiped out large dinosaurs in a catastrophic mass extinction.

Scientists named the new species Tongtianlong limosus, or “muddy dragon on the road to heaven”—a prosaic way to describe its final moments before death, mired in mud with its limbs and head outstretched, struggling to escape.

“This new dinosaur is one of the most beautiful, but saddest, fossils I’ve ever seen,” Steve Brusatte, of the University of Edinburgh’s School of Geosciences, says in a press statement.

This Dinosaur Wore Camouflage

A beautifully colored dinosaur fossil is the first to show evidence of countershading, a type of camouflage.

By

Surrounded by hungry predators, a little plant-eating dinosaur from the early Cretaceous did the only sensible thing. It donned camouflage.

Analysis of the exquisitely preserved fossil remains has revealed one of the most elaborate dinosaur paint jobs ever seen, including a brown back and a lighter belly. Modern-day antelope, fish and other animals have similar dark-and-light zones, which confuse predators, but this is the first discovery of such markings on a dinosaur.

“This one is unique,” says paleontologist Jakob Vinther of Britain’s University of Bristol, co-author of a study describing the fossil published in the journal Current Biology. “We can very clearly see that there are color patterns … stripes, spots.”
