A new caridean shrimp (Crustacea: Decapoda: Dendrobranchiata) from the Upper Jurassic Solnhofen Lithographic Limestones of Schernfeld (South Germany)
A new genus and species of caridean shrimps, Occultocaris frattigianii nov. gen. et sp., is described from the Upper Jurassic Solnhofen Lithographic Limestones of Schernfeld near Eichstatt (Lower Tithonian, Hybonotum Zone). It differs from other genera of carideans primarily in the armature of the rostrum in combination with the shape of the chelae of the first and second pereiopods.
Laser-stimulated fluorescence reveals unseen details in fossils from the Solnhofen Limestone (Upper Jurassic, Bavaria, Germany)

 Laser-Stimulated Fluorescence (LSF) has seen increased use in palaeontological investigations in recent years. The method uses the high flux of laser light to reveal details sometimes missed by ultraviolet (UV) and optical wavelengths. In this study, we compare the results of LSF with UV on a range of fossils from the Upper Jurassic Solnhofen Limestone Konservat-Lagerstätte of Bavaria, Germany. The methodology follows previous protocols with modifications made to enhance laser beam intensity. Our experiments show the value of LSF in revealing shallow subsurface detail of specimens, previously not widely applied to Solnhofen fossils. In particular, fossil decapods from the Solnhofen Limestone reveal full body outlines, even under the matrix, along with details of segmentation within the appendages such as limbs and antennae. The results indicate that LSF can be used on both vertebrate and invertebrate fossils and may surpass the information provided by traditional UV methods in some specimens.
Tertiary freshwater Decapoda (Crustacea: Parastacidae) from the Ñirihuau Basin, Patagonia, Argentina
Very well preserved specimens of a macruran decapod from the Lower (Lacustrine) Member of the Ñirihuau Formation, northwestern Patagonia, Argentina, permitted description of Lammuastacus longirostris, a new genus and species of Parastacidae. The sedimentological and paleontological evidences provided by the faunal assemblage indicate a freshwater environment. This is the first certain record of a fossil Parastacidae from Tertiary deposits, most probably Oligocene. The fossil material shows similarities with Geocharax, the extant Australian genus considered to retain many primitive characters, and other related genera from New Zealand and Chile.
