The Megalodon shark was a massive predator that lived during the Neogene period, approximately 2.6 million years ago. It is considered one of the largest predators to have ever existed, with estimates suggesting it could grow up to 52-59 feet in length and weigh up to 100 tons. Its diet consisted mainly of whales, sea cows, dolphins, and other large sea animals. The Megalodon's extinction is attributed to competition over food with other predators like great whites and orcas, which were more agile and could survive on less food. If the Megalodon had not become extinct, it would have continued to thrive in warm, shallow seas, and humans would have had to coexist with this massive predator. The video also mentions other prehistoric creatures that could have been a threat to humans if they had not become extinct, including the Jaekelopterus, the Sarcosuchus, the Megatherium, the Titanus, and the Titanoboa.
Here are the key facts extracted from the text:
1. Megalodons are believed to have lived during the Neogene period, approximately from the early Miocene epoch to the Pliocene epoch.
2. The scientific name of the Megalodon is Carcharocles megalodon, which means "big tooth".
3. Paleontologists believe that a Megalodon's size was between 52 feet and 59 feet.
4. A Megalodon's weight could vary from 70 to 100 tons.
5. The length of a Megalodon was equivalent to three full-grown great white sharks or almost two city buses.
6. A human tower of six or seven people could fit inside a Megalodon's mouth.
7. Two Megalodons could fit in an Olympic-sized swimming pool.
8. A Megalodon's weight was as heavy as 14 adult elephants.
9. A Megalodon's pectoral fins were similar to an airplane's wings.
10. Megalodons were the largest predators in vertebrate history.
11. Megalodons were estimated to have been 2-3 times stronger than a Tyrannosaurus Rex.
12. The bite force of a Megalodon was estimated to be 24,000-41,000 pounds.
13. Megalodons likely fed on medium to large aquatic animals, such as whales, sea cows, dolphins, porpoises, seals, and sea lions.
14. The second attack method of the Megalodon was to rip its prey's fins to immobilize it.
15. Megalodons likely went extinct due to competition over food with other predators, such as great whites and orcas.
16. The big tooth needed to eat approximately 2,500 pounds of meat a day.
17. The average American eats only 500 pounds a year.
18. Megalodons could only swim in warm, shallow seas.
19. Global climate change may have contributed to the extinction of Megalodons.
20. The migration of whales to cooler waters may have reduced the food source for Megalodons.
21. Researchers at the University of Zurich, Spay Lie-logical Institute, and Museum discovered the real reason for Megalodon extinction in 2016.
22. The Kosuke sempere otter could grow up to 39 feet and weigh eight tons.
23. The super croc was not an ancestor of modern crocodiles but more closely related to alligators.
24. The Megatherium americana was a giant ground sloth that was about 20 feet long.
25. The Titanus Waller II, or terror bird, was a flightless bird ten feet tall with a long neck and robust pair of legs.
26. The titanoboa SurroGenesis was a distant relative of the Anaconda and boa constrictor.
