How did the Iguanodon avoid destruction?
Iguanodon was considered to be a dinosaur of higher intelligence. Traveling in packs and having the option of running at high-speeds, these animals didn’t have to contend with many predators. Sometimes stray juveniles would be caught by lone carnivores but other than that, the Iguanodon did well with avoiding destruction of their species.
How fast was Iguanadon?
Computer models have also shown that the top speed of this dinosaur was about 12 miles per hour. That means it would travel about half as fast as a running human being or about the speed of a slithering snake. That doesn’t make Iguanadon very fast at all.
