New species of flying reptile identified on B.C. coast

11.01.2011
Persistence paid off for a University of Alberta paleontology researcher, who after months of pondering the origins of a fossilized jaw bone, finally identified it as a new species of pterosaur, a flying reptile that lived 70 million years ago.

Victoria Arbour says she was stumped when the small piece of jaw bone was first pulled out of of a fossil storage cabinet in the U of A's paleontology department.

"It could have been from a dinosaur, a fish or a marine reptile," said Arbour. "

Arbour, a PhD student in paleontology, says the first clue to the fossil's identify came after she compared it to known species of pterosaurs, "I found a previously published paper describing the teeth of a previously discovered pterosaur and ours was very close," said Arbour.

"The teeth of our fossil were small and set close together," said Arbour. "They reminded me of piranha teeth, designed for pecking away at meat." That led Arbour to believe her new species, named Gwawinapterus beardi was a scavenger of the late Cretaceous. "It had a wing span of about 3 metres and patrolled the sky and set down to feed on the leftover kills made by predator dinosaurs of the time such as Albertosaurus."

The fossil is not only a new species it's the first pterosaur of any kind to be found in British Columbia. It was found on Hornby Island, off the coast of Vancouver Island

However, Arbour says the place where the fossil was located has little to do with the actual area where the living pterosaur, was actually flying around 70 million years ago.

"In the late Cretaceous period, the B.C. coastal islands were about 2,500 kilometres to the south and part of what is now mainland, California," said Arbour.

Arbour's research was published in the Canadian Journal of Earth Sciences.

Im Focus: Flexible proximity sensor creates smart surfaces

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.

At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
