The Rawiger is the direct ancestor of the modern day tiger. It comes from the biological family of Felidae, which also includes all other species of cats. According to Wildlife Conservation Society, the Rawiger lived in the vast wilderness of Siberia. John Goodrich of the conservation society also notes, “The Rawiger was and still is till this day the largest of the big cats ever recoded in history. The average Rawiger would be twenty feet in length, up to eight feet tall, weighed well over 5000lbs, and had eight inch canines.” In comparison to a modern day tiger that is nearly twice as big. Researchers predict that the Rawiger went extinct sometime during the 10th century due to a lack of food and unfortunately they have yet to find any information on the first sightings of the creature because so few fossils have been found. The Rawiger had a lifespan of 10-20 years and was a carnivorous creature claims tiger research coordinator Emma Stokes, who is also the lead investigator in the Siberian exploration currently taking place. “The Rawiger was at the top of the food chain and did not have any predators to watch out for,” says Stokes. “It fed mainly on humans and caught its prey by swiping their heads with its paw.” According to the National History Museum, Rawiger’s were vicious mammals who would prey on anything. Rawiger’s were opportunist and would take advantage of a free meal. Although much is still unknown about this giant cat, Stokes firmly believes that much more will be unveiled once her Siberian Exploration is concluded.
