Answer:
. The Megalodon Shark Was The Largest Predator That Ever Lived. Reaching lengths of up to 60-70 feet and an estimated maximum weight of over 60 tons, the Megalodon is the largest known predator in Earth's history. The modern Sperm Whale is longer, but probably not as heavy as the Megalodon.
2. It is an extinct equine mammal, Equus quagga, of southern Africa, related to and resembling the zebra, but striped only on the forepart of the body and the head.
3.The dodo had a large body, stubby wings, a small, curved tail, short legs, and a large beak. The feathers of the dodo were grey, black and white in colour and the large curved beak of the dodo is one of it's most distinctive features.
4.The Blue whales, however, hold a unique reputation of being among the largest creatures on the surface of the earth measuring about a hundred feet. It, therefore, suffices to say that a blue whale is bigger than a Megalodon.
5.Evidence suggests an asteroid impact was the main culprit. Volcanic eruptions that caused large-scale climate change may also have been involved, together with more gradual changes to Earth's climate that happened over millions of years.
6.Humans and monkeys are both primates. But humans are not descended from monkeys or any other primate living today. We do share a common ape ancestor with chimpanzees. It lived between 8 and 6 million years ago.
