FIGURE 5. EDX spectra of an undetermined caridean shrimp (Eichstätt, Solnhofen Lithographic Limestones, Lower Tithonian, Hybonotum Zone, Riedense Subzone) (5.1) and its matrix (5.2), as well as of ?Sculda sp. (Hadjoula, Lebanon, Upper Cretaceous, Cenomanian) (5.3) and its matrix (5.4). X-axis shows the energy of the electron beam in keV, y-axis shows the counts of thousands of gamma-photons (kCnts). Beam times were for 5.1 = 45 sec., 5.2 = 36 sec., 5.3 = 100 sec. and 5.4 = 65 sec. Abbreviations for the elements: C = carbon, Ca = calcium, O = oxygen, P = phosphorus, Si = silicon. Note the peak of the phosphorus in 5.1 and 5.3, missing in 5.2 and 5.4.
