1. My god, Florida has oodles of gigantosaurus' in it because everybody binge eats at the all-you-can-eat buffet and never exercises, including the cops!
2. Dinosaurs no longer exist, that goes goes for gigantosaurus' as well since they all died out 65myo.
Gigantasaurus is used to describe humongousdinosaurs, but can be used for other humongous things not involving dinosaurs. Gigantasaurus is often confused with "Ginemenasaurus".
"Wow, That dinosaurskeleton is totally gigantasaurus!" "Gosh, this orange is so gigantasaurus..!"
