La Venta Monument 3 stands 1 @.@ 98 metres ( 6 @.@ 5 ft ) high and measures 1 @.@ 6 metres ( 5 @.@ 2 ft ) wide by 1 metre ( 3 @.@ 3 ft ) deep ; it weighs 12 @.@ 8 tons . Monument 3 was located a few metres to the east of Monument 2 , but was moved to the Parque @-@ Museo La Venta in Villahermosa . Like the other La Venta heads , its context has been radiocarbon dated to between 1000 and 600 BC . It appears unfinished and has suffered severe damage through weathering , making analysis difficult . It had a large headdress that reaches to the eyebrows but any details have been lost through erosion . Straps descend in front of each ear and continue to the base of the monument . The ears are wearing large flattened rings that overlap the straps ; they probably represent jade ornaments of a type that have been recovered in the Olmec region . Although most of the facial detail is lost , the crinkling of the bridge of the nose is still evident , a feature that is common to the frowning expressions of the other Olmec colossal heads .
