Issue Description

Cover image:
Microphotography of a gomphoterium cranium bone from Tepeticpac, Tlaxcala, observed in cross-polarized light. The morphology of the bone is observed: osetons and osteocite lacunae are seen as well as reabsorption of the bone visible in Haversian canals that have lost their oval shape. Photograph by Luisa Strualino and Sergey Sedov. See related article by Straulino et al. in this issue.
