Six New Dinosaurs Revealed After Study Analyzing Teeth - http://clapway.com/2015/08/08/six-new-dinosaurs-from-teeth-101/

Six new species of dinosaurs have been found after researchers from the University of Alberta analyzed theropod teeth from eight regions in Spain.


A Study On Teeth Revealed Six New Dinosaurs of the Theropod Species


University of Alberta researchers have quadrupled the number of known dinosaur species in Spain from only two species to eight new dinosaurs species. The research was conducted using 142 isolated theropod teeth from a part of the South Pyrenean Basin dated around the Late Cretaceous epoch.


The teeth analyzed in the study were from eight different localities in Spain, including Treviño County, Huesca, Lerida, and Laño. Though two species of theropod were already known, the researchers happened across six additional species during their research on dinosaur evolution at the final stages of the Cretaceous period.


The new species of theropod would have been present during the timeframe that spanned the Campanian age, which lasted about 83.6 million to 72.1 million years ago, and the Maastrichtian age, from 72.1 million to 66 million years ago.


The study was published in the journal Acta Palaeontologica Polonica.


More Teeth Means More Theropods For Researchers in Spain


Though the research was not initially to investigate the number of theropod species in the area, the sample of 142 isolated teeth revealed more species than researchers could have imagined.


Through analysis, the study concluded that a total of six toothed theropod species had lived in the area, five of which had been small, while the last one was large in comparison.


Angelica Torices, lead author of the study from the University of Alberta, believes the importance of the discovery may help lead paleontologists to better understand how the dinosaurs lived and what caused their extinction.


As no complete theropod skeletons have been revealed in Spain and the surrounding countries, paleontologists must rely on the smallest element available to know the timeline of dinosaur evolution: theropod teeth.


Though teeth may seem to be rather small, Torices and the other researchers say the teeth are the key to reconstructing the dinosaurs lives, especially in Europe during the Late Cretaceous ages.


Diversity of Carnivorous Dinosaurs in Cretaceous Europe


Theropods are a species of carnivorous dinosaurs who frequently lost and subsequently replaced their teeth. A massive number of teeth would be produced by one dinosaur during its lifetime.


These dental fixtures would fall out when the time was ready, only to be found millions of years later by scientists eager to learn more about the lives of theropods.


Though nothing else of the dinosaurs remained, the teeth showed their value in this study as their armed researchers with the knowledge that even the tiniest bit of extra information can help fill in the gaps in the evolutionary timeline of theropods.


The study researchers believe their findings have highlighted the diversity of carnivorous dinosaurs in Europe, but will also highlight how these dinosaurs and other large animals responded to climate change.


The fossil record may be incomplete for now, but at least the six new dinosaur species have been found thanks to a few forgotten teeth.

A New Raptor Fossil Discovered in China - http://clapway.com/2015/07/16/a-new-raptor-fossil-discovered-in-china567/

You know how the new Jurassic World film was pretty much all about the raptors in the movie? What’s not to like? They’re pretty charismatic on screen, and Blue had some awesome coloration.


Chinese raptor fossil found in Liaoning Province


Well, if you like dinosaurs, be prepared to become stoked about a real one; this new find in China of a raptor has been named the Zhenyuanlong suni. This type of raptor lived around 125 million years ago during the Early Cretaceous era.

The fossil was unearthed in the Liaoning Province, by a man named Sun Zhenyuan, who helped to get the fossil to the researchers for study. This is why fossil was named after him.


What do we know about the new raptor fossil thus far?


The research conducted on the fossil was made available today in Scientific Reports. The report was filed last year in November before it was accepted in April, then published today. There are two authors on this study; Junchang Lü and Stephen L. Brusatte.

Like many of the dinosaur fossils found in this region, this raptor is the relative of the Velociraptor we all have come to know from the Jurassic Park franchise. But it is also a feathered one as well, evident by the fossilized feathers, and research suggest it is closely related to birds given the anatomy structure of the fossil. The fossil is almost a full body skeleton.


raptor had wings?


The raptor fossil shows that it has probably around the height of a human and short appendages that looked like wings but probably couldn’t fly. There has been some joking or commentary that it basically looks like a human sized chicken or turkey, which is slightly scary if you have ever had to deal with aggressive poultry before.

One of the authors thought it was interesting to see the raptor fossil have winglike appendages without the actual intent of flying. The question then became why this dinosaur has wings, why has it evolved to have these in the first place. Other questions such as what its behavioral characteristics were begin to come to mind as well.

Only further research can be done to find out more about the fossil. That, and finding more similar fossils for further study.
