Jurassic Period, 199-145 million years BP. A fossil lobster in limestone-shale matrix with applied title labels 'Mesochir Longimaan'[sic] and 'Jurassic - Germany'; old collector's label to the reverse 'Mesochir / Longimaan / Jurassic / Solnhofen- / Germany'. 620 grams, 23cm (9"). Lincolnshire collection, UK. The spelling 'Longimaan' on both labels is an error for 'Longimann'. This designation appears to have been renamed subsequently. The difficulties of establishing an accurate taxonomy from a very sparse fossil record are tackled in the paper by D. Schram Decapod phylogeny: addition of fossil evidence to a robt morphological cladistic data set in Bulletin of the Mizunami Fossil Meum 2004. [No Reserve]
