How tall is rudy from ice age at his true height?

well, rudy is about the same height and length as momma rex, since we know that we compare momma rex to something sizable, like manny the mammoth, since the average height for a mammoth is 13 ft. and momma rex's head is roughly the same size as manny, momma rex's head is 13 ft. long, as tall as sue the biggest t-rex discovered. now momma rex's whole body is about 6 heads long it is 78 ft. long. now looking at the common height to length ratio for a t-rex we see that at the percentage of the height to the length is 32.5% since rudy and momma are 78 ft. long, the 32.5% is 25.32. so rudy is 25.32 ft. tall making it taller than spinosaurus aegypticus (the new one)
