  1. 4 summers to excavate it's remains? you know america is not the only place on earth right? people live in other parts of the world too where there don't have summer or fall or winter or Armageddon and have no idea what summer is, let alone 4 summers.

  2. Not only did the Spinosaurus got into turf fights with the Sarcosushus (37-40 feet long), but it fought against a dinosaur that SHOULD have been on this list: Carcharadontosaurus. A theropod that grew 43 – 46 feet long.
    Other notable facts about Spinosaurus were it's massive robust arms. 7 foot long arms with 13-15 inch claws similar to that of it's relatives Baryonyx and Suchomimus. Hunter on both land and water. Pretty much the closest thing to a real life Godzilla

  3. Who doesn't love dinosaurs? They are awesome! (but #2 Spinosaurus ergonomics were revised by paleonthologies and it does not look at all as shown on Jurassic Park film, it was a aquatic dino, and more a fish eater than a hunter)

  4. C'mon you committed so many paleo mis-steps in this video!
    (1) Retitle this "Top 10 Biggest PREHISTORIC Animals" ever. Stop the confusion! Pterosaurs are not dinosaurs… you make a good effort to make this clear, but it should be evident from the title.
    (2) Duckbill dinos were better adapted to dry habitats. Stop the amphibious dino confusion with the name.
    (3) The graphic you chose for Titanoceratops shows Triceratops is bigger.
    (4) There was a major study that just came out showing T.rex couldn't run very fast. If Giganotosaurus was as big or bigger, how the heck could it reach 30 mph!
    (5) And no love for Patagotitan?

  5. The list was generally well put together, but man you went with the jurassic park 3 spino instead of actually looking up the more recent facts about it that make it completley different… Just saying
