Comments

1. titanosaurs?
2. isn't the titanosaur the biggest
3. ARGENTINOSAURUS
4. BAROSAURUS? he might be bigger than argentinosaurus
5. Brontosaurus isn't even a dinosaur. This video was made a year ago? Seriously? It's been known for at least a decade that the Brontosaurus was a mistake. It was an Apatosaurus (?) body with a different head (Camarasaurus, I think?)
   Anyway, someone making a video like this should know better (or at least research a little better...)
6. Who's to say these 5 aren't all one and the same? I mean we've only found partial skeletons, a femur here, a neck vertibrate there...
   
   Fact is, we may never know as the black market for fossils is a complete mess and is ruining the whole thing.
7. Brachiosaurus
8. Garrafititan?
9. Can you imagine if the long neck dinosaurs were meat eating dinosaurs?
10. How about Brachiosaurs?
11. argentinosaurus is biggest
12. *what were. sorry, title bothered me enough to type it.
13. What about barosaurus?
14. how big can a creature get? i mean if provided with perfect planetary conditions.
15. Specimen BYU 9024 (a Barosaurus Lentus) is the largest known species of dinosaur to exist.
16. spuno
    is the biggest
17. amphichoelias is biggest
18. its amphicoelias
19. So many people be like "it was amphicoelias!" Well amphicoelias Altus was real but was much smaller than the animals in the video, and amphicoelias fragillimus is much bigger but not yet proven. Also, a lot of people in the comments need to learn to spell
20. so i guess no matter how hard i try ill never get a simple answer of the biggest dinosaur. Was it this, was it that. all i want is one word!
    _______________saurus!
