I made this from scratch. I stood in front of the Triceratops skeleton at the Field Museum in Chicago and drew it from several angles from observation to learn the proportions and posture. Then I sculpted it out in 123D Creature, a wonderful app that no longer exists, for iOS. I can't seem to find any other software out there that allows for such easy extrusion and multiplication of limbs! Any recommendations would be very much welcome.
