This period marked the earliest evolution of trees and their twiggy crowns were precursors to broad, flat leaves on the trees we see today. They reproduced through spores instead of seeds in the ancient forest. The paleobotanists walked across this land lost to time, exposed after 20 feet of soil and sandstone was excavated. They observed fossilized remnants of a surprisingly complex and lush world, including the identification of two new and unexpected species of prehistoric trees that grew as vines and moss-like patches.
