Once a time

Once upon a time, a scene appeared which seemed so far away.The top left is a wild beast ,like a dinosaur,farthest from the picture though still colossal.And the right one is a claw print, which also looks like hand bones. I want to show long time has passed by it.Then we see a curved trunk dividing the distant land  and the closer water.Here’s a fish shaking its tail to change its swimming direction.
