Lal-lo and Gattaran Shell Middens

The Lal-lo and Gattaran Shell Middens, located in the Cagayan Valley of the Philippines, represent a significant archaeological site that sheds light on the prehistoric human activities and dietary practices in Southeast Asia. Situated along the Cagayan River, these middens are composed predominantly of the freshwater clam species Batissa childreni. The site features large, varying deposits of shells, with some middens dating back to 2000 BCE and others as recent as 100 CE. The archaeological findings, including stone tools, bones, teeth, and intricately designed pottery, provide valuable insights into the resource utilization and lifestyles of ancient populations in the region. These middens' historical value is further acknowledged by their inclusion in the UNESCO World Heritage Tentative List, emphasizing their cultural and archaeological importance.
