    Probably should have "spared no expense" on the research budget. From the velociraptors' size, to the T-Rex's vision, to the lifting strength of pteranodons, the Jurassic Park franchise definitely prioritizes science fiction over science fact.

    I agree with you guys and all but they are genetically engineered animals and in the book, Wu mentioned moving to version 4.4 (I think) and they would change the dinosaurs to look like what people believed they looked like.

    The biggest inaccuracy of all, that dinosaurs evolved into birds!!! Lmao. And people actually ran with this when it was just INVENTED by Steven Spielberg. Can’t believe people actually believe this crap. I guess they miss the part where Alan Grant says that they are “warm blooded creature” and move in herds.

    • JD
      JD 4 days ago

      ​@Isaac Argueta Spielberg made dinosaurs popular again, but the people who really made the bird-dinosaur link popular were two paleontologists, John Ostrom and Robert Bakker. The former discovered and studied Deinonychus, the larger relative to Velociraptor, which would later inspire the Jurassic Park raptors, whereas Bakker popularized the idea that a creature like Deinonychus could not be a sluggish cold blooded creature, but instead an agile, active, intelligent warm blooded animal, and furthermore, he suggested all dinosaurs were so. The depiction of dinosaurs we see in Jurassic Park owes a lot to Ostrom and Bakker's studies and ideas.
      Also don´t forget Michael Crichton, who originally wrote the Jurassic Park novel; he did a lot of research on the latest paleontological ideas, and talked to scientists (including Ostrom and Bakker) about dinosaurs before he started writing. He adopted the (then relatively new) idea of active, warm blooded dinosaurs for his novel. So he deserves that credit too.
      Hmm maybe Grant does say something like that. I remember he directly asks Wu and Muldoon about their metabolism and whether they are warm blooded.
      Indeed, that is the current consensus, but why would that contradict the idea of birds evolving from dinosaurs?

    • Isaac Argueta
      Isaac Argueta 4 days ago

      JD I guess Spielberg made that theory popular. Didn’t know he got it from someone else honestly.
      Alan Grant says the Brachiosaurus (long Kneck) is “definitely a warm blooded creature” when he first sees it with Elly. Later in the same scene he says “they DO move in herds” to point out that they are not reptiles because reptiles don’t move in herds.
      They tried making a pterodactyl or pteranodon on a science show to show how it flew. They determined no reptile could ever fly because they are cold-blooded and would expense too much energy to fly. They HAD to be warm-blooded according to them. That’s the only way they could fly.

    • JD
      JD 4 days ago

      1. Steven Spielberg never invented the bird-dinosaur connection. It was already proposed by Henry Huxley in the XIX century; he studied the anatomy of Compsognathus and saw many similarities between it and birds. So the idea of birds being descended from dinosaurs is very old and has nothing to do with Spielberg.
      2. Alan Grant in the movie never says that dinosaurs are warm blooded; he probably believes they are, but he is unsure until the moment he actually goes to the park and receives confirmation from Robert Muldoon and Dr. Wu, who actually have first hand experience. Also, birds are warm-blooded animals, so what is your point there? And what about the moving in herds?

    Also, the velociraptors in Jurassic Park were based on either the Deinonychus or Utahraptors. Utahraptor would probably fit the bill better, as they found a skeleton in America and velociraptor are found in Asia.

    • JD
      JD 4 days ago

      Deinonychus was the inspiration behind the JP raptors. This was confirmed by Jack Horner, John Ostrom (the original Deinonychus expert, who was approached by Michael Crichton), Robert Bakker, and of course Michael Crichton himself. Utahraptor was announced during production or post-production of the movie; it was not yet known when the novel was written.

    ACTUALLY (sorry for saying actually so much) I did some research and found out that the velociraptor wasn’t messed up, it was actually a deinonychus. I don’t know WHY they called it a velociraptor, maybe it was the people being dumb and calling it a “VELOCIRAPTOR”.

    • JD
      JD 4 days ago

      It was Michael Crichton, the author of the Jurassic Park novel, who decided to use Velociraptor instead of Deinonychus as the name for his raptors; when he was researching for his novel, a famous paleontologist named Gregory Paul suggested that Deinonychus should be reclassified as a species of Velociraptor (Deinonychus antirrhopus). This is why Crichton mentions "Velociraptor antirrhopus" in the novel despite the fact that today such a combination would be invalid.
      Today it is considered that Deinonychus is too ancient and too different to be a species of Velociraptor, but at the time of Crichton writing the novel, it was seen as a novel, interesting idea, and so he went with it to be up to date. Also, he felt that Velociraptor was more evocative and would immediately strike readers as the name of a dangerous animal (velocity + raptor, bird of prey), whereas Deinonychus, although a badass name (means "terrible claw") is in Greek and not likely to be immediately interpreted by the average reader.

    5:57 I think you might be able to find the answer if you ever watch a crocodile and an alligator fight. In proportion to their size and jaw shape I think it would be a similar scenario. Alligators have the thicker build and wider jaw for catching land animals, and crocodiles have the longer and slimer jaws for catching fish.

    You fundamentally misunderstand the entire premise of the series. The books out line in a scene directly before Hammond meets his end by way of compies that the dinosaurs are not genetically accurate. Also you find out this is intentional and that they are made to look as the public would expect. Dr. Wu is actually not really a bad guy but found himself bound to work for Hammond through an InGen Contract. Hammond is the dirtiest of extreme capitalism and is meant to outline the price of greed. His argument with Hammond outlines this and other points. Then a whole different cast from the movies of people get eaten including Hammond after compies Poison and cripple him a juvenile T-rex comes along and eats him. Then all the survivors escape and they Nuke the island to kingdom come because it violated many international laws and posed a significant threat to the environment.

    The Ultimate theme is meant to drive home a warning about the dangers of genetic manipulation and tampering.
    For the movies Switch the attitude roles of Hammond and Wu with Hammond developing a conscious and Wu becoming the money grubbing villain Hammond escapes the island while Wu wasn't seen past the first few scenes presumably having left the island on the last ship. Apparently they also never nuke Isla Sorna and later think its a great idea to try again. You know give it a second chance what could go wrong. Trust I was a soldier and if it wasn't turned to glass the island would have a 24 hour UN blockade a water mines, and be restricted air space. How ever Jurassic world Did get one point correct they brought the story back to refocus on the main point that genetic tampering has dire consequences.
    In the books he only wrote Lost World at the request of his fans and is primarily just an adventure kinda sort of accenting the point of genetic ethics.
    In the movies Jurassic park 2 & 3 were studio grabs. The story is so chopped from the lost world book and even stuff from the first book that it was obviously the studio cashing in on the franchise.
    Since the true science employed is unethical genetic tampering and cloning Both stories are mostly accurate since the science employed is beyond most of our capabilities.
    All Crichton books have a morale theme.
