This animation is an excerpt of the "Colorado Geology: Ordovician-Silurian" video (in progress). Cooksonia were one of the first vascular plants to evolve on land during the Middle Silurian. They were about 1 to 3 cm in height. Note that no Cooksonia fossils have been found in Colorado. The animation is used to illustrate the early evolution of plant life.
