From Russia with Love-The Suprising Paleontology of the Russian Federation


Russia + fossils? Not a combination often thought of by many in fact Russia+Fossil Fuels is a more likely partnership. But, believe it or not the former Soviet Union holds a remarkable treasure trove of its prehistoric past. From the high arctic of Siberia to the flowing Volga Russia truly deserves a place on the fossil map. So, were to begin? The freezing permafrost of Siberia seems a good place to start. Most people who have an interest in the Ice Age and prehistory in general will have heard of the bounty of fossils the Siberian Tundra produces. Mammoth fossils in particular seem to attract most of the attention. Not surprising considering just how beautifully preserved the Mammoth fossils from Siberia are. But the truth is that really, they aren't fossils at all. The Mammoths lived here so recently (new theories suggest that they died out here 8,000-6,000 years ago)that their bones simply haven't fossilized yet. This process is aided by permafrost. Permafrost basically acts as a Pleistocene morgue, keeping the remains of Ice Age animals preserved in the frozen ground only a few inches down. This keeps the bones (and occasionally soft tissue) preserved for prosperity in mint condition. An example of just how crazy this preservation can be is Lyuba a mummified baby mammoth which now resides in the vaults of the Field Museum. Lyuba died over 10,000 years ago but every detail of her from her last meal to her hair is exquisitely preserved. It was purportedly in the possession of a Siberian indigenous tribe for many years before scientists finally found it. The tribal members couldn't thank the scientists enough for taking Lyuba. Stating that the dead mammoths possess 'evil spirits'. But its not only Mammoths found in Siberia. The remains of Horses, Reindeer, and Bison also frequently turn up. The Palaeontology of Siberia has been thrown into the limelight recently with the announcement of 'Pleistocene Park' a project spear headed by numerous Russian Palaeontologists and funded by the Japanese scientists attempting to clone the mammoth back from the dead. All questions of ethics aside the park is actually home to many animals. Mainly Caribou, Horses, and Bison but also including Wolves, Bears, Lynx, and the owner soon hopes Lions and Mammoths. Skipping across the Urals we soon reach the banks of the river Volga. The Volga is steeped in history most notably for the ferrying of Soviet troops to defend Stalingrad. But what of the prehistory of the Volga. Surprisingly many species of Ammonite can be found in the rocks here. The Ammonites date from the Upper Jurassic to Lower Cretaceous periods. The most common Ammonites can be found below (in order of appearance: Kosmoceras, Pavlovia, Australiceras, Peltoceras, and Audlioceras) As you can see the quality of these Volga ammonites is amazing especially the Peltoceras. No wonder many can fetch for up to 500 rubles on the Russian fossil market. These ammonites are found mostly in the oil sands on the banks of the Volga. Finally we take a short (in Russian standards) trip north to the rocks around St Petersburg. These rocks just like the Volga Ammonites yield some truly beautiful fossils. Trilobites. The Trilobites here are top quality and date from the Silurian/Ordovician periods. There are literally so many species that it would take eons (ok, maybe not that long) to list them. But I encourage you to look for yourself here: So, that's the rather surprising and amazing Palaeontology of the Russian federation.

Bone headed-Acrotholus audeti


You've heard of Pachycephalosaurus, and Stygimoloch right? Well say hello to the latest member of the 'bone headed' family: Acrotholus. Discovered in the Milk River Formation of Alberta, Canada, by researchers from the University of Toronto Acrotholus may be the oldest member of the group yet to be discovered. It pre-dates Pachycephalosaurus by 20 million years, The bones date from rocks that are 85 million years old. Being the oldest Pachycephalosaur yet to be discovered it offers researchers insights into the evolution of the 'bone heads' Around the size of a dog and weighing in at 40Kg Acrotholus is a rather small Pachycephalosaur. And it's size also sets it apart from the rest. "We can predict that many new small dinosaur species like Acrotholus are waiting to be discovered by researchers willing to sort through the many small bones that they pick up in the field," said co-researcher Dr Michael Ryan, curator of vertebrate palaeontology at the Cleveland Museum of Natural History. It has long been suggested that there is not a truthful reflection of small Dinosaur fauna's in existence as their tiny bones may have been to small to properly fossilize. However Acrotholus shows that when it comes to Dinosaurs. The small are just as important as the big.

Doggerland-Pleistocene Safari


Imagine a North Sea which is home to Bison, Horse, Megaloceros, Deer, Antelope, Elephants, Rhino, and Lions. Well you've just imagined Doggerland, a European Prehistoric Savannah that encompassed what is now the North sea between the UK, Holland, Norway, and Denmark. So, what kind of world was Doggerland and what was life like their in the Pleistocene 1.3 Million-10,000 Years Ago and it's untimely demise in 8,000 BC. Doggerland would have been a beautiful spectacle. Grasses and pasture would have stretched for as far as the eye could see, creating an ocean of grass. Grazing upon the grasses would have been herds of Reindeer, Rhino, Elephants/Mammoths, Horse, and Bison. that would have migrated up from Europe every summer to exploit this vast resource of food. Preying on these herbivores would be packs of Wolves and Hunting Hyenas along with Lions, Saber tooth cats, and Humans. Mammoths seem to be Doggerland's most famous resident. Dutch and British Trawlers often haul up Mammoth tusks and Bones in their nets from the seabed. Such fossils often find there way onto the commercial fossil market. Mammoths in Doggerland would have been migratory visitors as temperatures in the winter due to the close ice sheets would have been below freezing. This journey has been told in the BBC series Walking with Beasts in the final episode of the series 'Mammoth Journey'. Other prolific animals include the Bison and Horse. These creatures would have been literally everywhere on Doggerland their fossils are the most frequently dredged up from the muddy bottom. They would have been a delicacy to Cro Magnons living on Doggerland. However, these are not the same species of Horse and Bison left today. Instead they would have been older breeds and variants. The Bison belonged to the species Bison priscus or steppe wisent. They were stronger and larger than their American cousins. Their horns, vertebrae, teeth and bones can be found on many beaches in and around the North sea and English channel. Above: Bison Vertebrae from my collection. The Horses would have been different as well. They would have resembled Siberian wild horses with sticking up short manes and stocky bodies. Another famous resident is the Irish Elk or Megaloceros. This behemoth of a deer stood 6ft 6'' at the shoulder and had antlers that stretched 12ft from tip to tip. Megaloceros would have been a formidable opponent to any Human or Animal hunter alike. It's antlers could certainly pack a punch. Megaloceros would have engaged in mating displays and fights using it's antler in exactly the same way as modern deer. But why is this land full of enormous herds of herbivores and rich in resources no longer with us? One word. Tsunami. During the Mesolithic around 8,000 years ago Doggerland was very different to it's Pleistocene heyday. It was forested much like the rest of Europe and was home to Deer, Bear, Wolves, and the bad tempered beef that is the Aurochs. People were beginning to set up permanent homes in the forests looking to exploit the benefits of forest life. But nature had a different idea. Sea level rise caused by the melting ice was already flooding the low lying coast of Doggerland, diminishing the land. Then suddenly 8,000/7,000 years ago an earthquake in the Norwegian sea released a Tsunami right on Doggerland's front door. The Tsunami ravaged Doggerland. Sending much of it to the dark abyss. Some of Doggerland did remain exposed. But as sea levels rose more and more the last remnants of Doggerland a world once teeming with life succumbed to the waves.
