Re-Calculating Dinosaur Heights

Weird Science realizes it can't dunk on the raptors
 
Weren't they big enough already?

Figuring out how tall a dinosaur is would seem to be a fairly simple matter: line the bones up and figure out what its posture was like. But that's ignoring a rather significant factor, namely the cartilage that sits between the joints. In alligators, that cartilage accounts for about 10 percent of the hindlimb's length, leading to speculation that the dinosaurs might be significantly taller than their skeletons alone would suggest. How substantially isn't entirely clear, though. Birds, the only living dinosaurs, have less cartilage than alligators, but the immense bulk of dinosaurs might have required much more.
