Pseudodrobna natator n. comb., a new link between crustacean faunas from the Jurassic of Germany and Cretaceous of Lebanon

Dendrobranchiate shrimps are abundant in Fossil-Lagerstätten (where fossils exceptionally preserved). Despite their preservation, classifying them can be challenging as most diagnostic characters based upon extant species. Penaeus natatorGlaessner, 1945 (Late Cretaceous, Lebanon, Sahel Alma), is one of those cases which the systematic assignment species difficult. It was assigned by “default” to Fabricius, 1798, before being moved Metapenaeopsis Bouvier, 1905. The recent description Pseudodrobna kenngottiWinkler, 2017 Jurassic, Germany, Schernfeld, a Solnhofen-type Fossil-Lagerstätte) shows that natator should PseudodrobnaWinkler, 2017. This attests once again similarity composition crustacean faunas between Late Jurassic and Cretaceous Lebanon. We also discuss palaeoecological significance bilobed eyes, occur three from Alma: n. comb., Palaeobenthonectes arambourgi (Roger, 1946) Palaeobenthesicymus libanensis (Brocchi, 1875). These eyes seem have evolved convergently due deep-water dim-light palaeoenvironment these shrimp
