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.
Morscrangon acutus n. gen. n. sp. (Crustacea, Decapoda, Caridea) from the Fur Formation (Early Eocene) of the Islands of Mors and Fur (Denmark)
An assemblage of macruran decapod crustaceans discovered in the Islands of Mors and Fur (Denmark) was collected from the Fur Formation (early Eocene) and represents the basis for erecting a new genus. The studied specimens are ascribed to the new genus Morscrangon with M. acutus n. sp. (infraorder Caridea Dana, 1852, family Crangonidae Haworth, 1825). The family Crangonidae Haworth, 1825, was reported for the first time in the fossil record by Garassino & Teruzzi (2001) who described Crangon miocenicus from the lower Miocene of N Caucasus (Russia). Morscrangon n. gen. is the oldest report of this family in the fossil record, increasing its stratigraphic range from the early Eocene to Recent.
Organic constituents in process water from the in-situ retorting of oil from oil-shale kerogen
Capillary-column gas-chromatography/mass-spectrometry (GC/MS) was performed on the acid, base, and neutral fractions o'f liquid- and particulate-phase methylene chloride extracts of a composite sample of raw process water collected from separator Tank 6 by the Laramie Energy Technology Center. Of. the 160 extractable and chromatographable organic comP.ounds tentatively :identified, the following compou~d classes were found· (listed in decreasing order of. abundance):
