Ancient Denvers - Slimy Shoreline (Image 3)

Ancient Denvers - Slimy Shoreline (Image 3) Time Period: 250 million years ago - Late Permian (Paleozoic) The great Permian extinction, which took place about 251 million years ago, destroyed as much as 90 percent of all marine species and a lot of land-bound life as well. This post-extinction scene -- a tropical coastline much like the modern southern Persian Gulf coast -- is home to slimy mounds known as stromatolites. Formed by an unlikely partnership of photosynthetic bacteria and algae, these stinky, slimy mounds inhabit shallow and salty pools.

Using evidence from the core's rocks and sediment, and from geologic evidence gathered in other parts of the area, museum scientists, working with local artists, re-created several ancient Denver landscapes that depict Denver's amazingly varied past. The Ancient Denvers paintings were funded by the National Science Foundation (NSF) (grant EAR 98-05474). Ancient Denvers is an outreach effort of the Denver Basin research project at the museum. Primary funding for the Denver Basin Project was provided by NSF, the Colorado Water Conservation Board, the Colorado State Engineer's Office, the United States Geological Survey, the Colorado Division of Water Resources, Elbert County Commissioners, Jefferson County Open Space, the Colorado Natural Areas Council and Prima Energy.

See Next Image.] The Artists The artwork in the Ancient Denvers exhibit includes the combined talents of three experienced artists. --Donna Braginetz is known for her precise renderings of dinosaurs and other ancient life. She painted the first of the Ancient Denvers landscapes -- a reconstruction of the site of Denver International Airport as it looked 65 million years ago. The painting and the public's response to it were the inspiration for expanding the Ancient Denvers project to include thirteen additional landscapes. --Gary Staab is a well-known sculptor and painter of prehistoric animals. His work has appeared on the cover of Natural History magazine. Gary is a former employee of the Denver Museum of Nature & Science, where he created a number of sculptures for the Prehistoric Journey exhibition. --Jan Vriesen is a world-renowned painter and muralist. He is best known for painting murals that form the backdrops of museum dioramas. At the Denver Museum of Nature & Science, Jan's work can be seen both in the temporary Ancient Denvers exhibition, as well as in the Kansas Coastline diorama of the permanent Prehistoric Journey exhibition.
