When it comes to huge carnivores, there were no larger land animals than all the giant theropods we grew up with, and here is a list of my top 10 largest theropods.
#10 Edmarka rex/Torvosaurus:
One of the largest north american theropods, the largest specimen (CPS 1002) known from a scapula, is estimated at 11 m long, and probably upwards 3000-4000 kg
#9 Suchomimus tenerensis:
The largest specimen of this african spinosaurid (MNHN GDF 500) is estimated to measure 11.65 m (by Scott Hartman) and over 3816-4700 kg, some even claimed a weight of 5,200 kg was possible, the skull is 1.4 m long, and has over 90 non serrated,cone shaped teeth.
