The biggest dinosaurs that lived on Earth

[Jubatus]

I spoke to Nazir Ibrahim today, and he also said that he estimated the spino to be around the same weight as the Tyrannosaurus Rex (7-9 tons), but he said that there is no doubt that they could grow bigger. But still the Spinosaurus got a few meters on the T-Rex. But Dr.Dal Sasso who found what seems to be the biggest Spinosaurus skeleton ever said that he thought spinos could reach towards 20 meters. But you`ll never know until you got enough evidence to really pinpoint the real size. That goes for both T-Rex and Spinos.  But Spinos did had a lot of big competitors, both Carharodontosaurus (7-7.5 tons) and The giant crocs (Up towards 8 tons), so the Spino had to be big to be the dominant predator. It probably constantly had to compete with crocs in the water, and it had it compete with Carcharodontosaurus on land. There are even evidence of a fight with a large Carnivore, likely Carcharodontosaurus. So this competition gives the spino a lot of potential to grow to great sizes Reply
