Megalodons

A ground-breaking study offers an unprecedented reinterpretation of the extinct Megalodon, suggesting that this ancient shark was a slow swimmer that used its warm-bloodedness for efficient digestion and nutrient absorption. Contrary to its portrayal as a monstrous, fast-moving predator, the research proposes that Megalodon was an ‘average swimmer’, based on the lack of closely-spaced ridges on its minuscule ‘placoid scales.A recent study led by Professor Kenshu Shimada challenges the conventional view of the extinct…

Sharks are often imagined as lethal predators with rows of razor-sharp teeth and capable of zipping through the water at high speeds. But it seems in the case of the famous prehistoric shark Otodus megalodon, only one of those premises holds true.Forget Collars—There's a Kinder Way to Track Polar Bears in the ArcticIn a study published in Historical Biology, a team of researchers describe very small O. megalodon scales found in Japan. These sand-grain-sized placoid scales, or denticles, show up in elasmobranchs, a group…

Ethereum Megalodons Rise: Ethereum originated from trading platforms Genesis and Poloniex Ethereum Megalodons Rise: Ethereum bulls wake up after four years to transfer 22,982 ETH. According to Cointelegraph, both of them were last active five years ago, which is a signal of increasing activity of old ETH holders on the network, which leads us to certain conclusions. The activity of dormant addresses like the ones listed in Lookonchain’s post is not unusual: networks are constantly seeing a spike in the activity of…

Megalodons are known only from the teeth they left behind. Here, a megalodon tooth (left) is compared to a great white shark tooth. Each inch of tooth corresponds to about 10 feet of length: 20 feet for the 2-inch great white shark tooth and 60 feet for the 6-inch megalodon tooth. Encased in rock-hard enamel, teeth are more easily preserved than bones, let alone a shark’s cartilage skeleton. Shark teeth are one of the most abundant fossil types because sharks have existed for more than 400 million years, and the predators…

The fearsome megalodon was the largest shark that ever lived, possibly growing up to 20 meters (66 feet) in length, with teeth the size of a human hand. New research analyzing teeth from this ancient creature has revealed that the megalodon was the most apex of apex predators.  By studying the levels of nitrogen isotopes present in cells, scientists can figure out where a creature was in the food chain – because of the way the nitrogen is processed and excreted, nitrogen-15 builds up the higher in the food chain you…
