The San Bernardino County Museum in Redlands, California has a display of ancient artifacts from Central America: the countries south of Mexico and north of South America. From an archaeological perspective, Central America is also called the Mesoamerican Frontier and the Southern Maya Periphery.
In her entry on Central America in The Oxford Companion to Archaeology, Carleen Sanchez writes:
“Central American societies—seen as lacking in highly stylized art, sculpture, and mystery—are often typified as the poor cousins of their more advanced northern and southern neighbors. Nevertheless, prehistoric societies in this region demonstrate significant variability in social organization, religion, and material culture, reflecting a commingling of varying degree of Mesoamerican, South American, and indigenous cultural developments.”
Due to the Mayan influence in this region, some displays use Mayan chronology: Preclassic (2000 BCE to 250 CE); Classic (250 CE to 900 CE); and Postclassic (900 CE to 1521 CE).
