Only one of the three -in -three three predispiced natives shows

According to a research team from Bristol University, a new Devan’s gossip shows how the oldest members of the lizard group look, and something is surprising. The study has appeared today Nature.

Today, lizards and their relatives such as snakes, with the unique Tataras from New Zealand, are the most successful group of groundwater, of which more than 12,000 are specified – more than birds and more than the seizures. But what about lizards, snakes and tataras, which is collectively called lipidosoria, which has made them so successful?

It was always expected that the lipidosor had some roles of the lizard, such as partially hinged scalp, an open lower temporary bar, and a teeth on the roof of the mouth. These are all features of modern lizards and snakes that enable them to open their mouths in a super -wide (skull hunt) to manipulate the huge hunt and use teeth on the palate to catch small hunting.

The lower temporary bar is primarily a cheek bone, a bony stick that runs between the cheek and the jaw and today is absent in lizards and snakes. Snakes and many lizards have all these features, as well as some extra flexibility of the skull. Only Tatara has a complete lower temporary bar, which gives it an ancient look at some of the ancient and native animals. And it also has some large palm teeth.

“The new fiancée shows none of our expectations,” said Dan Mark, who led the project as part of the MSc study in Pale Biology in Bristol as part of the MSc study. “There is no teeth on his palate, and there is no sign of any hunger. Although, it has an open temporary bar, so one of the three. Not only this, but there are some surprisingly big teeth than his close relatives.”

“We often scan fossils in modern pelvicological studies,” said Dr. David White Side, co -supervisor of the project. “But the extraordinary resolution and quality of scans from Sancutron X -ray sources shows us all the best details and saves any risk of loss.

“MSc’s first student, whistleblower, worked on regular scans, and he found very small details, but it is very small – the skull is only 1.5 cm long, and we can barely see the teeth, so we were able to use two -to -two -to -two -to -two -to -two -to -two -to -two -to -two -to -two -to -two -to -two -to -two -to -two -to -two -sized -dalled -sighs In use, two powerful assemblies were able to use, two powerful assemblies, which could be used to use two powerful assemblies (UK).

“When you look at the foam, the whole skeleton sits in the palm of your hand,” said Michael Benton, another co -operative supervisor and professor at the School of Earth Sciences at Bristol University.

“But after the scanning and hard work of our students who cleans the scan data, we can see the most amazing details. The new animal has relatively large triangle -shaped teeth, and they are probably used to pierce and cut the hard cuts of its insect hunting.”

“The new animal is unlike anything to be discovered so far, and it has forced us to think about the evolution of lizards, snakes and tataras,” said Dan Mark. “We had to give a name to distinguish everything from everything, and we chose the Agroodontosus Hales Bipoteter, which means that after the formation of Helsby Sandstone, it was discovered, after which it means ‘harsh dental lizard from heelsbi rock’.

“This sample not only provides important information about the ancestral scalp of all lipidosors, but also builds on the growing knowledge that Tatara is often called ‘living fossil’, which is related to a diverse order of ancient crawling animals, which has a vigorous evolutionary history.”

The fossil is 242 million years, which is just in the middle of the trays, just before the dinosaur appeared, and since then the lipidosor has diversified in several stages, the initial people are slipping into and out under the feet of the dinosaur. Their success is debtor of their amazing ability to capture pests and other hunting, including their extremely flexible jaws, and, in the case of some snakes and lizards.

“When I got a sample on the beach of Devon in 2015, I didn’t know what it was because it was rarely exposed,” Dr. Rob Corum added. “It is great to see that such a wonderful fiancée has been coming from a site that has been providing focus for 150 years.”
