First time posting here but I would like to get some help with an issue I have.
I have a planet that has 30% more gravity than earth. I have terrestrial animals with an exoskeleton, they stand at a height of 1.2 meters. For context, they are bipedal and have a theropod-like body plan. I know I will need a biological material that is stronger than chitin that can provide adequate support while being lightweight. It will have to be able to withstand strong bite forces and flexible enough to absorb the shock of a landing from 10 to possibly 15 meters.
Is a bone exoskeleton a feasible solution here? Perhaps the weight of the exoskeleton would be too great?
