Large Solnhofen Jurassic Shrimp Crustacean Fossil - Antrimpos Speciosus . A well preserved large fossilised shrimp of the Antrimpos speciosus species, from Solnhofen, Germany, dating to the Late Jurassic, around 150 million years old. From the famous Lagerstatte deposits of Solnhofen, where some of the most astonishingly well preserved fossils have survived. The Shrimp is of unusually large size, and is of striking appearance on the textured limestone bed. The rostrum (head), abdominal segments, uropod (tail), pleopods (back legs) and pereopods (front legs) are all clearly visible and well preserved. A quite extraordinary set of circumstances, resulting in what are called Konservat-Lagerstatten, mean that these long dead creatures are exceedingly well preserved. In the Konservat-Lagerstatte of Solnhofen, the muddy bottom of the tropical lagoons that once existed in modern-day Bavaria, Germany, created an anoxic environment on which creatures fell when they died. The anoxic bed was a barrier to both bacteria and scavengers, preventing the decomposition and destruction of soft tissues for just long enough so that casts could form in the pressurised muds. In modern times the quarries of Solnhofen are mined for roof and floor tiles, with quarrymen regularly stumbling upon these prehistoric creatures, exceptionally well preserved in their stony graves.
