From these drawings, we know that this creature, which lived about 100 million years ago, was very big, it had tall spines on its back, forming a magnificent sail, and it had long, slender jaws, a bit like a crocodile, with conical teeth, that may have been used to catch slippery prey, like fish.
通过这些素描， 我们发现这种生活在 一千万年前的生物 体型非常的庞大， 它们的背上有高耸的脊椎， 形成了一条巨大的尾巴， 下巴非常的细长， 像是鳄鱼的嘴一样， 牙齿是圆锥型的， 这可能是用来捕食 很滑的食物，例如鱼类。
