Fossils used to make the 3D-reconstructions. A-E Beremendia fissidens. A and B, upper and lower view of MPZ 2018/467, C fragment of anterior part of maxilla MPZ 2018/468, D fragment of maxilla with M3 MPZ 2005–491, E labial view of complete mandible with teeth MPZ 2018/469. F-I Dolinasorex glyphodon, F lower view of one concreted and incomplete skull MPZ 2010–512, G lower view of another concreted and incomplete skull MPZ 2010–201, H upper view of a complete mandible MPZ 2010–579, I lower view of a fragment of maxilla that preserves the posterior part and the M3 MPZ 2010–27.

Reconstruction of Beremendia fissidens.
A. Separation of the elements of the main fossil, lower view. B. Upper view of the maxilla used. C. M3 insertion part reconstructed. D. Frontal view of the original maxilla with teeth mirrored. E. Lower view of the reconstructed skull. F. Oblique view of the skull with the mandibles mirrored and collocated. G. Superimposition of the skull of B. brevicauda. H. Final reconstruction with the adapted skull of B. brevicauda. Different colours indicate different 3D objects.

Steps in the division and reconstruction of Dolinasorex glyphodon.
A. Reconstructed part of one skull, divided into the sectors that were subsequently mirrored. B-C. Upper and lower views of the reconstructed snout. D. Reconstruction with the snout and mandibles. E. Superimposition of the snout with complete nasals. F. Superimposition of the skull of B. brevicauda. The part with the worst adjustment is marked. G. Final reconstruction with the adapted skull of B. brevicauda. Different colours indicate different 3D objects.
