    • Strewn conch shells noted in 2008 to 2017 that pertain to sea floods of the past 1,000 years on Anegada, British Virgin Islands

    Metadata Updated: January 21, 2026

    This part of the release provides an updated georeferenced catalog of strewn conch shells pertaining to extreme waves on Anegada, a low Caribbean island perched south of the Puerto Rico Trench. Three of the listed fragments were found whole, lacking any extraction hole from fishing. Others listed each contained a round hole from extraction of the meat in precolonial time. Still others were found too fragmentary to show whether they had been fished. Most of the fished shells listed are from the East End of Anegada. There, the listed shells in the south are near heaps of fished conchs, while the shells in the north rim an area of two hectares or more across which conch shells are strewn.
