Note

A true holy grail for fossil and cone shell collectors: a gigantic, museum-grade specimen of Conus adversarius (Conrad, 1840) measuring a staggering 99.37 mm! This specimen is a potential World Record Size (WRS). While the average size for this extinct species ranges between 40 mm and 65 mm, and anything over 80 mm is considered large, this absolute monster flirts with the maximum biological limit of the species, making it an incredibly rare investment piece. Why this shell is extraordinary: Unique Sinistral Evolution: Conus adversarius is famous worldwide as the only species in the entire Conus genus that evolved to be entirely left-handed (sinistral). Unlike 99.9% of all other cone snails which are right-handed (dextral), this extinct predator stands completely alone in evolutionary history.Gigantic Record Size: At 99.37 mm, this shell sits at the absolute pinnacle of known discoveries, practically tied for the #1 spot in world record size databases. Geological History: This beautiful fossil dates back to the Plio-Pleistocene epoch (approximately 2 to 4 million years old) and was recovered from the famous fossil beds of the southeastern United States. Condition: Excellent fossilization, sharp shoulder, and highly defined sinistral aperture. Shell No.: 1303.
