Dinosaur news!

I have a huge backup of dinosaur news to post about - so let's see if I can't get through some of this before heading to work.

China's earliest fossils of small carnivorous dinosaurs discovered

(Chinese paper)

Fossils of a small carnivorous dinosaur, which lived in the same period with the Lufengosaurus were recently discovered, in Lufeng and these are currently China's earliest fossils of small carnivorous dinosaurs, according to the Lufeng National Dinosaur and Geological Park in Yunnan Province on Oct. 7.

Experts have deduced that it was able to run fast and possessed predatory abilities. Therefore, it is a kind of small carnivorous theropod dinosaur and the rock formation in which the fossils were discovered was formed 180 million years ago during the early Jurassic period.

The fossils are single dinosaur skeleton fossils with a relevant complete overall shape. The morphogenesis of the skeleton including the skull, vertebrae, rachis and ribs are clear, while the tailbone was damaged.

A research group led by Dong Zhiming, a well-known dinosaur expert in China, studied the fossils and theorized that the dinosaur is more than 1 meter long and 0.7 meters to 0.8 meters tall, and it walked on two feet and has two forelegs and sharp teeth.
How dinosaurs conquered the world!
Toronto: Dinosaurs didn't need to kill other animals to become world beaters, says new research.

According to Canadian and US scientists, dinosaurs - the most powerful creature ever to walk on earth - did not spread throughout the world by killing other creatures but because of a natural catastrophe that wiped out their competitors.

The scientists have come to this conclusion after studying the new dinosaur, named Sarahsaurus, discovered in Arizona where this animal lived about 190 million years ago. It is believed that dinosaurs originated in South America and then rapidly spread out to every corner of the world, overwhelming all the animals in their path.

But the new discovery of Sarahsaurus challenges that view. "Until recently, we have viewed dinosaurs as very successful animals that outcompeted other species wherever they went,'' according to Prof Robert Reisz of the University of Toronto, who studied the species with Prof Tim Rowe of the University of Texas and Hans-Dieter Sues of the National Museum of Natural History in Washington.

"But this study puts dinosaurs in a very different light-that they were more opportunistic creatures that moved into North America only when a mass extinction event made eco-space available to them,'' the Canadian scientist is quoted as saying.

Ugh - gotta get ready to work instead of blogging - and these links aren't even that good. Bad on me - if you do read this, I'm sorry. I hope to put something of some entertainment up some time soon.

I take requests?
