Key facts

• The video begins at the San Lorenzo Tenochtitlán museum with El Rey, the largest head found at San Lorenzo. The museum labels the Middle Preclassic from about 1800 BC; the video separately claims occupation reached about 3000 BC, which is not the established date.
• Sixteen colossal heads are securely attributed to the Olmec; a possible seventeenth from Costa Rica is disputed. Published estimates put the largest San Lorenzo head, El Rey, at about 28 metric tonnes.
• The heads were carved from grey basalt from the Sierra de los Tuxtlas, called the Sierra de Latusha in the video. The approximately 90 km transport distance is the video’s estimate. Quarry and workshop debris supports rough shaping and working in stages.
• The roughly 44-ton weight for Altar 4 is the presenter’s calculation, not a standard published weight.
• The lecture presents the claims about thousands of columns being moved for column tombs, no human remains being found, and acidic soil dissolving bone. Acid dissolution is offered as an explanation, not a demonstrated cause.
• The column sizes and weights—2–7 tons on average, a 12-foot example at 13–15 tons, and a fallen 20-foot example at roughly 20 tons—are the presenter’s own measurements.
• Pre-Columbian America had no domesticated draft animals, so the Olmec relied on human labor for monument transport. The claim that their transport effort exceeded the Egyptian comparison is the presenter’s interpretation.
