Fig. 12 in Unusual environmental conditions preserve a Permian mesosaur-bearing Konservat-Lagerstätte from Uruguay

Fig. 12. Partially articulated Mesosaurus tenuidens skeleton (FC−DPV 2156) from the Early Permian Mangrullo Formation (Northeastern Uruguay). A. General view of a fragment showing an internal mass of elements that are here interpreted as a gastric content. B. Close up view of the area delimited by the white rectangle in A, showing some of the identified elements (arrowheads point to small bones, probably from a very young mesosaur; arrows point at pygocephalomorph carapaces and abdominal segments). C. Another close up view of A, to show thoracic pygocephalomorph segments preserving part of the endofragmal skeleton (arrowhead) and the remains of a specimen that clearly shows still articulated thoracic and abdominal segments (arrow).

FIGURE 5 in A novel application of the white light/fringe projection duo: recovering high precision three-dimensional images from fossils for the digital preservation of morphology

FIGURE 5. Processed views of a fossil sample acquired by the optical FPP system OTY. Each view is re-oriented 60º degrees with respect to the prior. Where: "a" indicates a zone that has no information at 60º in this stage of the process and will be corrected with the information of the next view, as is shown in "b".

FIGURE 3 in A novel application of the white light/fringe projection duo: recovering high precision three-dimensional images from fossils for the digital preservation of morphology

FIGURE 3. Magnitude maps of the sample obtained every 60º for 8 and 128 pixels/period. The images show the resolution and detail levels given the number of fringes projected over the sample. The measurements' accuracy of surface and depth depends on the number of projected fringes, which include as many as the system can display (8 pixels/period for each fringe in this case). When the acquisition of details is difficult, a wider fringe is required (based on our sample size, we used 128 pixels).

FIGURE 2. Flowchart of the 'OTY' procedure employed in this study, where: α = angle (60º in this case), * = MBE algorithm (Gutiérrez-García et al., 2013), and ** = Goldstein algorithm. OTY: name given to the white light system together with the phase shifting algorithm filter, based on the fact that it was developed for use on Ototylomys samples (see main text).
