Just so you know it can be ridden underwater. While riding it your oxygen wont deplete and its a very fast swimmer. Its attacks can insta-kill trilobites and collect a huge amount of chitin at the same time. They can also be carried by pteranodon and above so you can easily transport them to different places, and easily pick them up and tame them elsewhere.
Great for harvesting chitin abd silica pearls from trillobites. Deals extra dmg to them and can usually kill 2-3 at once if they're close enough together. Adding movement speed will make it fast enough to outrun anything underwater with ease.
