San Lorenzo Colossal Head 7 was reworked from a monumental throne ; it was discovered by a joint archaeological project by the Instituto Nacional de Antropología e Historia and Yale University , as a result of a magnetometer survey . It was buried at a depth of less than 1 metre ( 3 @.@ 3 ft ) and was lying facing upwards , leaning slightly northwards on its right hand side . The head is poorly preserved and has suffered both from erosion and deliberate damage . The headdress is decorated with a pair of human hands ; a feathered ornament is carved at the back of the headband and two discs adorn the front . A short strap descends from the headband and hangs in front of the right ear . The head sports large earflares that completely cover the earlobes , although severe erosion makes their exact form difficult to distinguish . The face has wrinkles between the nose and cheeks , sagging cheeks and deep @-@ set eyes ; the lips are badly damaged and the mouth is open , displaying the teeth . In 1986 the head was transported to the Museo de Antropología de Xalapa .
