We describe for the first time small «25 mm) dorsal paramedian, lateral, and appendicular /ventral scutes (osteoderms) of aetosaurs from the Blue Hills in Apache County, east-central Arizona. These diminutive scutes, collected by c.L. Camp in the 1920s, preserve diagnostic features of the common Adamanian aetosaur Stagonolepis.

An approach to extract watersheds and watercourses, as well as their corresponding valleys and hills, from images with subpixel precision is proposed. The critical points of the terrain are essential as the starting points for the construction of these separatrices. They are extracted efficiently with subpixel precision using an approach based on derivatives of Gaussian filters. The separatrice...
