mapusarus would win in a fight because spinosaurus only ate fish so its teeth were small and brittle plus it was only 18 to 20 feet tall so spinosaurus would not win under any cercomstanses
Spinosaurus would be able to win this pretty easily, considering Baryonyx was much smaller.
Spinosaurus, Giganotosaurus, Tyrannosaurus, Carcharodontosaurus, Mapusaurus, Tyrannotitan, Acrocanthosaurus, Suchomimus, Deltadromeus, Oxalaia.
spinosaurus because it's bigger
1. Giganotosaurus 2. Spinosaurus 3. Carcharodontosaurus 4. Mapusaurus Epanterias and Saurophaganax may be bigger than T-Rex and a new mystery carnivore has been discovered in Argentina that may be bigger than both T-Rex and Giganotosaurus.
my money is on giganotosaurus!!!Good answer, whoever answered this. But what did you bet? All your money? Well then, you win then! Giganotosaurus carolinii evolved from Carcharodontosaurus saharicus. Since it evolved from it, Giganotosaurus is more advanced.But he is just a little smarter, in other words, he is almost as dumb as carcharodontosaurus. But the species lived and died 97 million years ago, evolving into mapusaurus roseae. Carcharodontosaurus, however, lived 7 million years, that is 100-93 million years ago. they both have something dumb in common; they are lone hunters! So they probably could've been defeated by the fast, the advanced, and the smart mapusaurus roseae.
A Spinosaurus Just because they are bigger and have more muscle mass and their claws are more useful, but it does matter what type of terrain.
spinosaurus
Carnosaurus, allosaurus, giganatosaurus, meglasaurus, mapusaurus, ceratosaurus, albertosaurs, baryonax, tarbosaurus, nanotyranus, spinosaurus, allioramus, suchumimous, carcharadontosaurus,yangchuanosaurus, and good old Tyrannosaurus Rex.
Tyrannosaurus
Actually it depends on what type it is if it was a bloodthrsty spino it would knockout the t rex but it is true that a spinosaurus is a better fighter and if u diaagree please answer differently
The T.rex is the "King of the Dinosaurs" so it means that it can defeat anything on it's way.
It is true that Spinosaurus was larger Tyrannosaurus. However, there is no possible way paleontologists could know which would win in a fight. The fact that Spinosaurus was larger would presumably give it an advantage, but it's all conjecture.
