In present-day Chiapas, Mexico, archaeologist Robert Rosenswig, remote-sensing specialist Ricardo López-Torrijos, and colleagues have located 41 smaller settlements surrounding the ancient Mesoamerican city of Izapa. The researchers have concluded that these settlements were culturally linked to Izapa because each of the settlements is the same age and configured in the same manner as Izapa, with a pyramid to the north and a plaza to the south. Their shared structural orientation suggests that residents of the settlements likely performed some of the same cultural ceremonies as residents in Izapa did.
