An easy tame a nd easy to make saddle these are probably the best early to mid game utility dino you can get. They have good carry weight and decent attack damage and if you put levels in health you can use it to easily transport items across dangerous areas
Started on a new server and went through the trike tame to start the utility farming. Next day got an iguanadon and explored how it is used and what it can do. 5 minutes later I retired the trike to the egg farm.
The iguanadon is a great ground transportation, berry farming, small Dino killing, maneuverable and an overall great Dino. Jump off a cliff, no damage. Need to chase something to tranquil it, pull out your weapon and shoot while you ride. IMO level weight and speed and you've got a great utility ride!
