Dude, I was just correcting some mistakes. You don't need to be sour about it. Maybe with the heliocorpion, I mis-read but I never heard of a mosasaur reaching up to 18 metres. I've heard of them getting close well a few cases most grow up to 14-15  metres. http://jurassicpark.wikia.com/wiki/Mosasaurus mosasaurus in jurassic world was 18 metres long.
