Guess you're right but i'm still pretty sure that the megalodon is much bigger than that, the thing i'm most certain is that it can at least fit a car in its mouth
I just wanna clear things up, because I'm a dinosaur freak, brontosaurus isn't brontosaurus. He's an apatosaurus. Apatosaurus was found first, and later more bones were found that were believed to be another species,which was named brontosaurus but they were just more apatosaurus bones. Also megalodon was about as long as a school bus, nowhere near as large as a blue whale.
And they're both significantly smaller than the blue whale.
