When Ichthyosaurs Led a Revolution in the Seas

Loading...
  • Published on: 25 June 2019
  • The marine reptiles Ichthyosaurs arose after The Great Dying, which wiped out at least 90 percent of life in the oceans, changing the seas forever and triggering a new evolutionary arms race between predator and prey.

    It's funny how these documentaries talk like they know exactly what happened and how they lived back then. Now we are starting to figure out dinosaurs were covered in feathers but we are suppose to believe what u guys are saying right? Lol.

    According to the WWF there may be 100 million species. With a yearly extinction rate of 0.01% at least 10,000 are gone a year. Could there be another Great Dying (1:52)? Unlike that extinction the one going on now seems to be caused mostly by Homo sapiens sapiens.  😱 😭

    They lasted for 157 million years, but my ancestors from the start of that time still have living descendants, so who was the better survivor?

    I like these prehistoric fish because of the dinosaurs movie of the 2000's. It told stories about multiple dinosaur species from the giants flying across seas to mate n other little ones trying to survive the long dark winter nights.
