Whale Evolution

  • 50 BCE

    Pakicetus - 50 MYA

    Pakicetus - 50 MYA
    The earliest ancestor of the whale. A quadrupedal mammal with a size similar to a modern-day wolf.
  • 49 BCE

    Ambulocetus Natan - 49 MYA

    Ambulocetus Natan - 49 MYA
    An evolution of the Pakicetus in order to hunt more efficiently underwater. Gained a wider tail and a more streamlined body, as well as shifting the hind legs to act as flippers.
  • 46 BCE

    Rodhocetus - 46 MYA

    Rodhocetus - 46 MYA
    A large leap from the Ambulocetus Natan. A shorter, more powerful neck is developed, muscles are present in the tail, and hind legs are longer and more flipper like. The kidney develops a method of filtering out saltwater, allowing for extended periods of time underwater.
  • 39 BCE

    Basilosaurus - 39 MYA

    Basilosaurus - 39 MYA
    An evolution of the Rodhocetus that makes it large enough to me considered a saurus. The Basilosaurus is longer in shape, has enhanced eyesight, and improved underwater hearing.
  • 36 BCE

    Basilosaurus Dies Out - 36 MYA

    Scientists believed that the basilosaurus died out 36 million years ago.
  • 30 BCE

    Ancient Whale - 30 MYA

    Ancient Whale - 30 MYA
    After a 6 million year dark period, the Basilosaurus returns as the Ancient Whale. At this time, the Megalodon is their main predator, so they flee to colder waters to avoid the Megalodon.
  • 30 BCE

    Predatory Toothed Whale - 30 MYA

    Predatory Toothed Whale - 30 MYA
    An evolution of the Prehistoric Whale that adapted to hunt in darker, colder waters. Developed echolocation to navigate waters that they could not see in.
  • 1 BCE

    The Modern Day Whale

    The Modern Day Whale
    over the last 30 million years, whales have evolved into the over 80 species present today. Below are a few members of the whale family.
  • 1 CE

    The Orca Whale

    The Orca Whale
    Orca Whales, or as they're also called, Killer Whales, are the largest member of the dolphin family. In captivity they live anywhere from 10 to 45 years.
  • 1 CE

    The Sperm Whale

    The Sperm Whale
    The Sperm Whale is the largest toothed whale, and the largest predator in the whale family. The Sperm Whale gets its name from its spermaceti, a waxy substance found in their heads that is used for lamps and candles.
  • 1 CE

    The Dolphin

    The Dolphin
    Although it may not seem like it, the Dolphin is part of the whale family. Related to the Orca Whale, they have the same traits as a whale, such as two front legs and a blowhole, as they cannot breathe fully underwater.
