Between 800 and 200 BCE a new migratory group expanded through the Caribbean island: the Saladoid. This group is named after the Saladero site in Venezuela, where their distinctive pottery (typically distinguished by white-on-red painted designs) was first identified. The introduction of pottery and plant domestication to the Caribbean is often attributed to Saladoid groups and represents the beginning of the Ceramic Age. However, recent studies have revealed that crops and pottery were already present in some Archaic Caribbean populations before the arrival of the Saladoid. Although a large amount of Caribbean Islands were settled during the Archaic and Ceramic Age, some islands were presumably visited much later. For example, Jamaica has no known settlements until around 600 AD while the Cayman Islands show no settlement evidence before European arrival.
