Here is a fossil Limulus from Sonhofen of the species Mesolimulus walchi from the late Jurassic of Eichstätt. This fossil horseshoe crab shows a rarely detailed preservation and also a clear death track.Although the fossils of Mesolimulus walchi from the Plattenlak belong to the best preserved Limulus finds worldwide, the preservation of the substance is usually rather weak. This is the reason why there is rarely an UV picture of horseshoe crab fossil to see. Usually it is just not much to see under UV light. Maybe some sports and flackes of organic residue. Also z.b. Solnhofen Ammonites usually do not show much under UV light.In contrast, with this fossil horseshoe crab offers a lot of details on the UV image. This fossil also shows the last foot steps in the life of this very horseshoe crab.The fossil track of a Solnhofen limulus is described under the Ichnospecies Kouphichnium lithographicum. These Limulus trace fossils were originally discussed as tracks and traces of fish like amphibians or creeping traces of Pterodactylus or even birds like Archeopteryx.This limulus track is nice and clear visible. The fossil limulus itself is about 104 mm long.All together this is a fantastic story telling fossil from the lithographic Solnhofen limestone.
