The secret of the mass grave of Pachyrhinosaurus in Canada

Alberta is a massive cemetery on a hidden monumental scale under the slope of a lush forest in Canada.

Thousands of dinosaurs were buried here, and at once was killed.

Now, a group of paleontists came to the Gorge of Boreston – called “Death River” – to help solve a 72 million-year-old landing – how did they die?

Trying to work full place here begins with a heavy holiday of Sledgehammer.

Emily Bamforth, who is leading gas, is needed to open a thick thick thick layer covering Professor Emily Bamforth, which describes as “Palaeo Gold”.

The team, the elimination of the dirt and dust layers, as a thinner work begins, slowly begins to squeeze the flowing bones.

“It has a large piece of bone

“After that, there are all these long, skinny bones. These are the ribs. This is part of a foot. This is nothing of a pipeline cavetry.”

BBC News has come to the Toreston greek to witness the transparency of the previous cemetery and brought together the clues of researchers.

Thousands of fossils were collected from the site and constantly formed New discoveries.

The bones are all about a dinosaurine called Pachyrhinosaurus. Types and profiles, in a newly remarkable BBC series – Dinosaurs in Dinosaurs, which use visual effects and science to carry out the world before this date.

These animals living during the late bretacous period were triceratops relative. Measuring about five meters long and weighs two tons There were big heads of four-legged animalsIt is decorated with a different bone frill and three horns. Their identification feature was a big bulge on a boss called a boss.

The boring season has started new and lasts up to autumn annually. Fossils in a small place where the team worked on the team is incredibly intense; Prof Bamforth, each square meter has up to 300 bones.

So far, the team has made the size of a tennis pitch to dig an area, but the bones reach a kilometer of a kilometer.

“This is a jaw in terms of density,” he said.

“We believe that this is one of the largest bone beds in North America.

“More than half of the world’s known dinosaurs are described in one example. We have thousands of patchesaurus here.”

Palaeontologists have moved to a place of hundreds of miles of dinosaurs in the south – the places of winter – for the summer.

In the area, which has a hot climate, which has a hotter than today, it was covered in a rich vegetation, it would be to provide plenty of meals for a group of animals eating.

“This is a single sort of animal species in time, and this is a great example size. This is almost never in a fossil record,” says Prof Bamforth.

And northwestern Alberta this patch was not just a pachyrhinosaurus house. Even larger dinosaurs toured this area and learn to try and understand this ancient ecosystem to learn them.

Two hours walked away, we reach the hills. Heavy forest, walking or doggy-paddling reaching there – quickly along a river running fast and scrambled over slippery rocks.

No drilling is required here; Super-sized bones lie near the coastline, washed in rock and cleansed with water, it is just waiting to be selected.

A giant vertebra is quickly stained, the teeth scattered from ribs and mud.

Palaeontologist Jackson Swever is interested in things that look like a part of Dinosaur Skull. “The majority of what we found here is a duck of ducks. If this skull has a hull, this is a great dinosaur, which is probably 30 feet (10 m),” he said.

Another grass, another grass, forests walked like a patchyrhinosaurus, and PalanEontologists help build a picture of this ancient country.

Sweden is a collection manager in Philip J Currie Dinosaur Museum for cleaning and analyzed and analyzed and analyzed and analyzed both of these giants. A giant Pachyrhinosaurus, which is about 1.5 million long and nicknamed “Great Sam”, works on the skull.

He points to where the three horns are in the ardent head, but one in the middle is missing. “All the skulls who do not listen are a spike in this place,” he says. “But it doesn’t seem to be a beautiful little unicorn spike.”

Over the years working on the emergency site, the museum gathered 8,000 dinosaurs and covered in fossils in the lab; There are the bones of a young man who are older than young people.

Many animal owners from such animals allow researchers to answer questions about how types, species grow and how to grow the makeup of the society is about dinosaur biology. Also, to see individual changes, to see how a pachyrhinosaurus can get out of the flock – there can be a great deal of work in the Great Sam and the missing spike.

All these detailed research helps to answer the team vital in the museum and two sites: how many animals in the bulleton gorge do these animals died at the same time?

“We believe that if this is not a whole flock, it was a flock in seasonal migration, which is effectively deleted, if it was not a good ratio,” he said.

All arguments show that this catastrophic event is a flash flesh – perhaps a storm of the mountains that do not stand towards the flocks, the roots and stones that change the roots and stones.

Prof Bamforth says Pachyrhinosaurus will not have a chance. “These animals cannot move very fast due to its transparent numbers, and they are very heavy, and they are not really good in swimming.”

The rocks found on the site indicate rotating the sediments from flowing water. As if it is destroyed, it is frozen in time as a wave in the stone.

But for dinosaurs, this nightmare day is now a dream for paleontologists.

“We know that every time it comes here, we will find the bones 100% guaranteed. We discover something new about the species each year,” he says prof.

“So we continue to go back because we still find new things.”

As the team gathers the tools ready to return another day, they know that there is a lot of work ahead. We only scratched the surface of those here and there are more mysteries before the date waiting to emerge.

New series with dinosaurs begin on Sunday, 25:25, BBC One BBC starts with all episodes available in BBC IPlayer in BST.
