The Ortoiroid people were the second wave of human settlers of the Caribbean who began their migration into the Antilles around 2000 BC.
They are believed to have originated in the Orinoco valley in South America, migrating to the Antilles from Trinidad and Tobago to Puerto Rico.
[5] The two earliest Ortoiroid sites in Trinidad are the Banwari Trace and at St. John's Road, South Oropouche, which date back at least to 5500 BC.
[10] The Ortoiroid are considered the first settlers of the archipelago of Puerto Rico;[7] however, recent reexamination of data, artifacts, and agricultural evidence and assumptions about culture have suggested a more complex picture.
[8] Shellfish remains have been found at Ortoitoid sites indicating that they constituted an important part of the diet.
[9] Ortoiroid artifacts include bone spearpoints, perforated animal teeth worn as jewelry, and stone tools, such as manos and metates, net sinkers, pestles, choppers, hammerstones, and pebbles used for grinding.
