Ancient Rainforest Revealed in Illinois Coal Mine

Scientists exploring a mine have uncovered a natural Sistine chapel showing not religious paintings, but incredibly well preserved images of sprawling tree trunks and fallen leaves that once breathed life into an ancient rainforest.
Replete with a diverse mix of extinct plants, the 300-million-year-old fossilized forest is revealing clues about the ecology of Earthâ€™s first rainforests . The discovery and details of the forest are published in the May issue of the journal Geology.
â€œWeâ€™re looking at one instance in time over a large area. Itâ€™s literally a snapshot in time of a multiple square mile area,â€ said study team member Scott Elrick of the Illinois State Geological Survey (ISGS).
Over millions of years as sediments and plant material pile up, layer upon layer, the resulting bands become time indicators with the newest, youngest layer on the top and the oldest layer at the bottom. Typically geologists peel away a vertical slice of rocky material to look at material, including fossils, over a period of time.
A coal mine offers a unique view of the past. Instead of a time sequence, illuminated in the layer upon layer of sediments, the roof of an underground mine reveals a large area within one of those sediment layers, or time periods.
Miners in Illinois are used to seeing a few plant fossils strewn along a mineâ€™s ceiling, but as they burrowed farther into this one, the sheer density and area covered by such fossils struck them as phenomenal, Elrick said.
Thatâ€™s when they called paleobotanist Howard Falcon-Lang from the University of Bristol in the United Kingdom and William DiMichele, a curator of fossil plants at the Smithsonian National Museum of Natural History.
"It was an amazing experience. We drove down the mine in an armored vehicle, until we were a hundred meters below the surface,â€ Falcon-Lang said. â€œThe fossil forest was rooted on top of the coal seam, so where the coal had been mined away the fossilized forest was visible in the ceiling of the mine.â€
Hereâ€™s what the miners and other scientists saw underground: Relatively narrow passageways wind through the â€œcave,â€ marked off with stout 100-foot-wide pillars to ensure the roof doesnâ€™t collapse.
â€œItâ€™s like in some bizarre Roman temple with tons of Corinthian pillars that are 100 feet across and only six feet tall,â€ Elrick told LiveScience. â€œAs youâ€™re walking down these passageways you see these pillars of coal on either side of you and above youâ€”imagine an artistâ€™s canvas painted a flat grey and that is sort of what the grey shale above the coal looks like.â€
The largest ever found, the fossil forest covers an area of about 40 square miles, or nearly the size of San Francisco. This ancient assemblage of flora is thought to be one of the first rainforests on Earth, emerging during the Upper Carboniferous, or Pennsylvanian, time period that extended from about 310 million to 290 million years ago.
A reconstruction of the ancient forest showed that like todayâ€™s rainforests, it had a layered structure with a mix of plants now extinct: Abundant club mosses stood more than 130-feet high, towering over a sub-canopy of tree ferns and an assortment of shrubs and tree-sized horsetails that looked like giant asparagus.
The scientists think a major earthquake about 300 million years ago caused the region to drop below sea level where it was buried in mud. They estimate that within a period of months the forest was buried, preserving it â€œforever.â€
â€œSome of these tree stumps have been covered geologically speaking in a flash,â€ Elrick said.
Because the spatial layout of the forest has been maintained, the scientists can learn about entire plant communities, not just individual plants.
"This spectacular discovery allows us to track how the species make-up of the forest changed across the landscape, and how that species make-up is affected by subtle differences in the local environment," Falcon-Lang said.
The fossil forest extends along the ceiling of two adjacent mines, the Riola mine and the Vermillion Grove mine, which are located in Vermillion County, just south of Danville, Ill.

Rapa Nui is our mascot, because:
"Easter Island was given the name Rapa Nui (Great Rapa) by Tahitian sailors, in the 1860's, as it reminded them of Rapa - a small island in French Polynesia. Today, the land, people and language are all referred to locally as Rapa Nui. Rapamycin (also called sirolimus) is a peptide that was isolated in 1975 from the bacteria strain Streptomyces hygroscopicus found in a soil sample on Easter Island. Rapamycin is used to help prevent the body from rejecting organ and bone marrow transplants. It is also being studied as a treatment for cancer and tuberous sclerosis. Rapamycin belongs to the family of drugs called immunosuppressants."
