Bivalves of the Mazon Creek Fauna were filter-feeders that lived in and on the mud and sand in shallow water. They were so common in some areas that one collecting locality was dubbed “Chowder Flats.” Evidence learned from comparing other marine assemblages suggests that the Essex Fauna bivalve assemblage lived in poorly oxygenated and brackish water.
After collecting fossils as a hobby for many years growing up, Dave Douglass opened Dave's Down to Earth Rock Shop in 1970 at the age of 20 (with the help of his parents) at 1312 Chicago Avenue in Evanston, Illinois. The shop contained minerals and fossils, mostly self-collected by the Douglass family.
