Worst dinosaur theories

TYRANT KING - Oh, how fun! I remember an absolutely bloody terrible theory that suggested Tyranosaurus Rex circulatory system was so weak that it would have to stop moving every 20 minutes or so just to catch its breath and recover its strength! Not a very intimidating tyrant, don't you think? Thank you so very much for sharing this with us! :)

I never heard that one. It's so freakin stupid.

t.rex was a scavenger cause it weighed over six tons, yet a even larger spinosaurus was a macro predator according to jack Horner.

Don't forget the "Tyrannosaurus was a scavenger" hypothesis..

Carcharodontosaurids not being able to ram because their skulls may shatter is based on the fact that the Premaxilae and Maxila bones are relatively thin.. say, compared to that of Tyrannosaurus. This however, doesn't mean they couldn't ram...in fact Planet Dinosaur actually showed two male Carcharodontosaurus individuals engaging in a "head butting" behavior that could be plausible

I think their skulls were very strong.

feel free to add other theories.

Liopleurodon(not a dinosaur but still) was upwards of 125 feet long and weighed just as much

Sauropods were brainless, walking walls of meat

Stegosaurs had a 'second brain' near their hips

Prerodons picked up things with their feet.

Don't forget Paleocosmology! The theory of dinosaurs living in space!

Never heard of that. It sounds dumb.

Monsters Ressurected: Spinosaurus. 'Nuff said. 

id say the thoery of Trex having week cardiovascular System is quite posible given that it woould need many leeters of blood per second to achive high speeds, but this could be negated due to posibly Trex beeing like A cheatah, fast for short distance speed but needing to rest if the hunt got to prolongated

 while the worst theory is the one of Dinos beeing crushed by there weigth

JRR, just saying, but by that logic, pretty much any large carnivore has a weak cardiovascular system. 

rexsTrex a have strong cardiovascular systems.

Worst for me is the theory of aliens from outer space having planet Earth as the PERFECT place to land the extraterrestial creatures on this planet...

Aliens exterminated dinosaurus.

MYSTIQUE - Hahaha! That Monsters Resurrected episode was completely ridiculous! I remember watching it when it first aired and thinking "Wow! That is completely baseless conjecture applied to a Hollywood monster!". :)

TYRANT KING - Yeah! They did it so they could build Transformers! ;)

The theory that the Pachycephalasuarus could headbutt others of its species. To be fair, it was very likely at the time but now with x-rays we can see that the dome was hollow, any impact with another pcahy would most likelywould have killed it.
