Fig. 7 in Triassic coleoid beaks and other structures from the Calcareous Alps revisited

Fig. 7. Coleoid cephalopod Phragmoteuthis bisinuata (Bronn, 1859), lower Carnian, Upper Triassic, Schindelberg, Lower Austria. EDS data on geochemical composition of shale and fossilized remains. A. NHMW 2006z0235/0007, silicified shale. B. NHMW 2006z0235/0012, calcified proostracum. C. NHMW 2006z0235/0010, high content of Ba and S in the shale in intimate contact with black sheet on a top of proostracum, indicative a life time organic material. D. NHMW 2006z0235/0010, carbonized black sheet (mantle) on a top of proostracum. E. NHMW 2006z0235/0007, carbonized ink sac content.
