Presented by Dr. Leif TapanilaIdaho State University: The Phosphoria Sea was centered in Idaho during the Permian time period, 280 million years ago, and its seafloor rocks extend today from Nevada north through Utah, Idaho, Wyoming, and Montana. Recent studies mapping environments and fossils show that the Phosphoria Sea supported a diverse marine ecosystem including the top predator on the planet, the buzzsaw shark Helicoprion. The Phosphoria Formation is perhaps best known for its rich deposits of phosphate ore that have been mined for over a century in eastern Idaho. However, this formation contains abundant chert deposits that alternate with carbonate and phosphate units. In places, the chert comprises the bulk the Phosphoria Formation. Where are all these cherts coming from?  Early researchers recognized sponge spicules in thin section, suggesting a sponge origin of the silica. But only recently has the source of chert been found in place... and it's spectacular.
