Jurassic Solnhofen Shrimp
Dusa sp.
Solnhofen Limestone (Upper Jurassic Tithonian)
Eichstatt, Germany
Shown here is a good example of the genus Dusa. The genus is characterized by a short and delicately serrate superocular spine. The cephalothorax is short. The third pair of walking legs is longer than the others. This is a relatively rare genus from Solnhofen. The plate is 9.5 inches by 10 inches and is rimmed with beautiful manganese oxide dendrites. The antennae are restored.

The Solnhofen Plattenkalk, or Solnhofen limestone, is a Jurassic Konservat-Lagerstätte that preserves a rare assemblage of fossilized organisms, including highly detailed imprints of soft bodied organisms such as sea jellies. The most familiar fossils of the Solnhofen Plattenkalk include the early feathered theropod dinosaur Archaeopteryx preserved in such detail that they are among the most famous and most beautiful fossils in the world. The Solnhofen beds lie in the German state of Bavaria (Bayern), halfway between Nuremberg (Nürnberg) and Munich (München) and were originally quarried as a source of Lithographic limestone.
