The lepidodendron

You were walking down a forest when you find a well. you look inside it and see it is very deep. you tie a rope around the well and your waist to climb up in case of emergency, but it snaps. You fall down and hit the ground, and you pass out. When you wake up, you find your self laying on the floor of a weird forest, not the same as the one you were just in. It looks old, and decayed. You look around and see that all of the trees around you have leaves that are pointed down like they are rotten and the trees don't even have any brances on the lower or middle part of them. The trees are very tall and you come up close to one, to see that the bark has a texture of scales. you look up and realize where you are. You are in 300 BC, away from the year you were in. You see that there are Lepidodendron trees everywhere and giant bugs about the size of hippo and others the sizes of houses and you.
