text: The eurypterids are intimately associated with numerous fishes and land plants in a dark gray to black bituminous shale with numerous single grains of coarse, round, frosted quartz sand, and clusters of these sand grains in pockets, along with small light-gray mud pellets (phosphatic?), some sulphur specks, selenite crystals, pyrite and coaly or carbonized streaks which probably represent mineralized plants.
