What are top 20 biggest land carnivore animals ever?

Top twenty would be hard, but suffice it to say all were theropod carnivorous dinosaurs.

Spinosaurus may have been the longest, at 55 feet, but was somewhat lighter than Tyrannosaurus Rex. Giganotosaurus was nearly as big as T Rex, and so was Allosaurus Amplexus. Allosaurus Fragilus, Allosaurus Atrox, Ceratosaurus were some of the smaller theropods.
