 In April 2010, archaeologists discovered the 2,700-year-old tomb of a dignitary within Mound 11 that is the oldest pyramidal tomb yet discovered in Mesoamerica.According to archaeologist Bruce Bachand, the tomb exhibits Olmec rather than Maya affinities.This tomb predates by 600 years any other such tomb found in Mesoamerica, such as those at Tikal, and at Kaminaljuyu.
