Many artifacts have been found, among them wooden busts and rubber balls.
Wooden busts Of particular note are 37 wooden busts or sculptures recovered from the bogs in 1989 by
INAH archaeologists, during the third excavation phase at El Manatí. These busts were unusually well-preserved, owing to the
anaerobic conditions of their interment and a stable water temperature that impeded microbial decay. The wooden busts were usually accompanied by other objects. For example: • Sculpture 1 was associated with a wooden staff and a dark green ax (
celt). • Sculpture 2 was associated with a large
obsidian flake, tied bundles of leaves and plants, a
hematite ball, a pile of sandstone rocks "common to a number of other sculptures," as well as fragments of human infant bones. Nearby to its east was the skeleton of an infant. • Sculptures 5, 6, & 7 were interred as a group, each laid on their sides in a triangle, facing inward. These sculptures were associated with bundles of plant material and were covered with a mat. An incomplete wooden staff and an infant cranium were associated with this burial. Some of these heads were stolen and later found in
Germany in the hands of archaeological object traffickers. According to Mexico, these artifacts were stolen in the 1980s and passed through the hands of antiques dealer
Leonardo Patterson, who later transferred the artifacts to Germany. These artifacts ended up in the
Bavarian State Archaeological Collection. In 2018, the two heads were repatriated to Mexico.
Rubber balls Twelve rubber balls associated with axe offerings were found El Manatí in 1989. Their surprisingly excellent state of preservation led archeologists to suspect that the balls had received a
vulcanization type process, and it was found that the balls were made of two types of vulcanized
latex.
Ceremonial axes In addition to the dozen rubber balls and 37 wooden busts, excavation has turned up many
jadeite ceremonial axes (
celts), pottery,
greenstone beads arranged in clusters (likely once two separate necklaces),
"baby-face" figurine fragments, carved wooden staffs, ritual obsidian knives (with no evidence of use), bones of newborn or unborn infants, and human and animal bone fragments. Most of these objects within the bog were found to be carefully arranged rather than haphazardly deposited, pointing to a sacred sacrificial intent.
Infant bones The bones of the newborn or unborn infants consisted of some whole skeletons as well as dismembered
femurs and skulls. These remains are particularly intriguing since they point to the possibility of
human sacrifice, a ritual without direct evidence in the Olmec archaeological record. The infant remains are each associated with, and subordinate to, the burial of a wooden bust. It is not known how the infants died.
Cocoa traces On July 30, 2008, INAH reported that testing of residues found in a ceramic container in El Manatí, dating from approximately 1750 BCE (at least between 1900 and 900 BCE), show that the container contained a
cocoa drink base probably consumed by the elite of the site. The ceramic vessel, which has slightly divergent cylindrical walls, a flat bottom, black spots and a red
slip on its bottom, was associated with other sumptuary objects. It is believed that this type of vessel was used for drinks such as "chicha" (maize beer), chocolate, and
atole preparations which were consumed only by priests or other people of high social prestige. Content verification tests yielded the presence of
theobromine, an essential cocoa component; chromatography and UV tests detected ions of cocoa's chemical components. This evidence predates other evidence found in Mayan areas of
Belize and Puerto Escondido,
Honduras. == Olmec technology ==
