Early Triassic, 250 million years ago (Lykins Formation). The Permian ended with the largest mass extinction in geologic history of 90% of marine life and much life on land. This scene shows the tropical shoreline that developed about one million years later in an arid shoreline setting at Red Rocks Park near Denver. The mounded features are called stromatolites, and consist of cyanobacteria and algae. These features only grow in a few places today, generally shallow, salty areas.
Organisms depicted: cyanobacteria and algae in stromatolitic mounds
