In 2002 the mortichnia of a horseshoe crab was found in lithographic limestone in Bavaria, Germany.^[2][1] The trail measured 9.7m and was left about 150 million years ago when the crab died in an anoxic lagoon.^[1] The footprints left enough evidence for researchers to determine that the creature probably fell into the lagoon upside-down, righted itself, and started walking before succumbing to the anoxic conditions of the water.^[1] The trackway is currently exhibited at the Wyoming Dinosaur Center.^[3]
