Most findings (about 50 to 100) were ceramics but as well there was found small stone artifacts like relief heads made of stone. What for do You need this info ? You may visit 2 collections. One at the small museum at the Rio Cuale island and the second at the C.U.C. University, where as well is a archeologist. I do not remember the name of the woman but I am sure asking around You will find here. As far as I remember she was argentinian. Please take note that the University does not have an archeological department.
