If you play by yourself you can tame a velonasaur by using a tranq creature and tranqing it while constantly moving in circles to dodge its needles or by being on a rock/small cliff then tranqing it In my first time taming one I was on a cliff and the velonasour couldn't attack me I was using a slingshot so it was hard.one last way to tame it is to use a tanky creature and tranq it while your dino is risking his life
