ABSTRACTTwelve specimens of early Toarcian Mecoptera and Diptera from the vicinity of Wolfsburg were investigated for the present study. The material was found during house building activities in the 1980s at the locality Große Kley in Mörse, an urban district of the city of Wolfsburg, Lower Saxony, Germany. The specimens were found in calcareous nodules of the Harpoceras falciferum Zone that occur within the Liassic black shales (Posidonia shale). Six specimens of Mecoptera, five belonging to the family Orthophlebiidae and one belonging to the Bittacidae, and six representatives of the following Diptera families were identified: Ptychopteridae, Limoniidae, Anisopodidae and the superfamily Mycetophiloidea. The fossil fauna of Wolfsburg is similar to that of other early Toarcian sites in Germany, described by Handlirsch (1906, 1939), Bode (1905, 1953) and Ansorge (1996) from Braunschweig, Dobbertin and Grimmen. Two new species are described, Mesorhyphusulrichi sp. nov. (Anisopodidae) and Archipleciomima germanica sp. nov. (Mycetophiloidea).

Green Pigments

The results of analyses of coloured plasters are given in the paper. The samples come from traditional folk earth houses from SE and Central Moravia and were chosen so as all of the most common colours of the Central European folk architecture are present among them: red, yellow, blue, green, and black. The analyses were conducted by the means of light microscopy, which is also a powerful tool for stratigraphical analyses, X-ray diffractometry, Raman spectrometry, end electron microanalysis. Hematite of industrial origin was identified as the red pigment, the yellow one was formed by yellow earth, which also may be a precursor for traditional production of red dye. The widest used blue pigment was ultramarine in the 19th and the first half of 20th century in Moravia. The analysed green pigments were formed by an organic dye of green earth and the black one consisted of soot. Based on the sort and composition of pigment and plaster, the age of the material is also discussed.
