Trek through Time Graphics, Silurian

The Trek through Time is a short walk through the woods at the Reston National Center. It contains 16 plaques including an introduction, and 15 depicting different time periods in the Phanerozoic. Each plaque has an artist's rendition of plants and animals typical of the time period, plus information on the climate and positions of the plates at that time. This is the Silurian plaque.
