Cusirisna Cave was discovered in the 1870s by Dr. Earl Flint, an explorer for the Harvard Peabody Musuem. The human remains and artifacts found in the cave were collected and sent to the museum, where they have remained since, unanalyzed. In December 2011, Dr. Clifford T. Brown and I analyzed the osteological material and artifacts because we thought they might be related to the Preclassic cave complexes of neighboring Honduras, an idea originally suggested by Dr. James Brady. I analyzed the human remains while Dr. Brown studied the artifacts. This thesis presents the results of the analyses and compare the findings to other mortuary complexes in Mesoamerica. Despite the paucity of material culture, information regarding context, and the small sample size, I propose Cusirisna as a place of exceptional ritual importance. This project adds to our understanding of cave bioarchaeology, mortuary practices in Mesoamerica, and the prehistory of Nicaragua. / by Kendra L.
