ends pressure re-touched and with base or extension; prismatic knives, some altered to make projectile ends, pins, cutters and knives, among others. Ornaments: extraordinary quality appraised, mainly tubular and spool earflaps, some are so thin that are translucent; also found some beautiful samples of "bezotes" (worn by high chiefs). Ritual: green obsidian ornaments as rich offerings for high rank individuals. Such is the case of pieces found within skull in some burials, as if these were placed in the person's mouth; these pieces are spherical or semi-square and always of green stone. In these same conditions a small rectangular piece was found, with an edge perforation, of a dark green stone and so polished that it seems mirror. As far as Shell and Bone items, without a doubt the most important Purépecha culture items found here were made from these materials. The presence of these materials demonstrates that the settlers maintained contact with people from both coasts, whether for commerce or some other type of interchange, for example: Small trimmed snail necklaces with perforations. Circular Hoops catalogued as bracelets... human soldiers’ figures, naked without gender beings, and with a hieratic position, dancers with a shell incrusted forming an eye. Human burials containing human bones found in Huandacareo: Shaft Tomb excavated in tepetate that resembles the El Opeño, (Jacona, Michoacán) from the Preclassical period, although the Huandacareo tomb, from the cultural materials found as offering, it must be placed in the period immediately previous to the arrival of the Spaniards; the burial found corresponds to a primary burial of an old person and to a secondary burial of an adult. Six tombs were built on a perfectly outlined patio, one of them unfinished; there is another one associated to this group with the same characteristics; the walls are made with stone blocks perfectly cut and jointed with mortar; the floor is compacted earth; the tombs are covered by large stone slabs, some with worked edges. The location dimensions of six of them is very interesting as they were constructed symmetrically; in the central part of the group, the slab forming the roof of tomb number 2 serves as weight to number 4, that is oriented perpendicularly, with a cruciform aspect although in fact they are two rectangles. Each grave contained remains of an adult primary burial accompanied by rich and numerous offerings consisting of pottery, shell objects, bone and stone tools.
