These sharks lived in warm shallow tropical waters all over the world during the Miocene and Pliocene epochs (which lasted from 23 million to 2 million years ago).įossil remains of Megalodon are commonly found in coastal regions and riverbeds where they have been exposed by erosion. All their fossil teeth that measure at least 6 inches and larger, are extremely rare and are highly valued. Megalodon means “big tooth” in Greek, and this name is very fitting because these sharks had teeth that were up to 7 inches (18 centimeters) long! Megalodon sharks could reach lengths of up to 60 feet (18 meters), which is twice as long as a Great White Shark. Scientists believe that Megalodon sharks fed on large marine mammals such as whales. The Megalodon are extinct animals that is considered to be the largest shark that ever lived in the sea, so all that we can see of them today are their fossil specimens. Great white sharks primarily eat fish, seals, and dolphins. These sharks are apex predators, which means that they are at the top of the food chain. Great White Sharks are found in all major oceans and prefer waters that are between 59☏ and 75☏ (15☌ and 24☌). It is also one of the largest predators in the sea, with some individuals reaching lengths of up to 20 feet (6 meters). The Great White Shark is one of the most well-known sharks in the world. In this blog post, we will take a closer look at the Great White Shark and the Megalodon to see how they compare. Although the two species appear to share many similarities, there are also several key differences between them. Two of the most popular sharks are the Great White Shark and the Megalodon. They are powerful predators that have been around for millions of years and come in all shapes and sizes. The extinction of this iconic giant shark likely impacted global nutrient transport and released large cetaceans from a strong predatory pressure.”Ĭheck out a video explaining the researchers’ work below.Sharks are some of the most fascinating creatures in the sea. “These results suggest that this giant shark was a trans-oceanic super-apex predator. Megalodon bite marks had been previously found in prehistoric whale fossils, and a foraging model made by the scientists found that eating a single 8-meter-long (26-foot-long) whale may have allowed the shark to swim thousands of miles across oceans without eating again for two months.Ĭatalina Pimiento, a professor at the University of Zurich and senior author of the study, said: For extinct animals we can estimate the body mass with modern 3D digital modelling methods and then establish the relationship between mass and other biological properties such as speed and energy usage.” “Weight is one of the most important traits of any animal. They completed the model by adding “flesh” around the skeleton using a 3D-scan of the body of a great white shark from South Africa.Ĭo-author John Hutchinson, professor at the Royal Veterinary College in the UK, said: They then attached the column to a 3D scan of a megalodon’s teeth from the United States. The research team, which includes researchers from Switzerland, UK, USA, Australia and South Africa, first measured and scanned every single vertebra, before reconstructing the entire column. The megalodon vertebral column from the Royal Belgian Institute of Natural Sciences is therefore a one-of-a-kind fossil.” However, their skeletons are made of cartilage, so they rarely fossilize. ![]() “Shark teeth are common fossils because of their hard composition which allows them to remain well preserved. Against all odds, a sizeable portion of its vertebral column was left behind in the fossil record after the creature died in the Miocene oceans of Belgium at the age of 46 about 18 million years ago.Īccording to first author Jack Cooper, a PhD student at Swansea University: Researchers made a 3D model of one individual megalodon which was discovered in the 1860s. Scientists have made a three-dimensional model of how big the extinct Megalodon shark was - big enough for it to eat prey the size of modern killer whales.
