There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

Sorry but I'm not agree...
Indeed, in my own opinion spinosaurus was a fishs eater dinosaur. Thus not as powerfully built and performing predator as tyrannosaurus rex...
Did Allosaurus live in prides ?  Constantly in prides as do the african lions today ? OK by opportunism they could be able to hunt together. So could the tyrex. Compared to tyrex, they seem slender (2-4 tons aginst 7-9 tons for an adult tyrex). Much more slender than african lion compared to tiger.
But this is not very important. I don't want to haggle.


 

 

Some large Allosaurus species can grow up to more than 40 feet, so they are not too small to be the analogy for the African Lion.

So the large Allosaurus species are only slightly smaller than their Allosauroidae cousins such as the Giganotosaurus and Carcharodontosaurus, just how coincidentally similar that the giant specimens among the African Lion are also only slightly smaller than their Pleistocene lion clade cousins.
