Jurassic Solnhofen Shrimp
Antrimpos sp.
Solnhofen Limestone (Upper Jurassic Tithonian)
Eichstatt, Germany
Shown here is a good example of the genus Antrimpos. The genus was formerly known as Penaeus. It is characterized by an elongated third pair of legs. Antrimpos is represented in the Solnhofen deposits by several species. It is the most common genera of shrimp found in these deposits. This slab is 8.5 inches by 6 inches and has some attractive manganese oxide dendrites.
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.
