Fossilized giant Clam (Tridacna Gigantea)
PUFO261-1
This fossil Giant Clam shell (Tridacna gigantea) was found at the Southeastern border of Kenya using GPR (Ground Penetrating Radar) as it was 3 meters deep. This clam species became extinct during the late Pleistocene period, around 180.000 years ago.The annual increase of the size of the shell has been estimated at 1cm / year (thesis by C. Lazareth. 2017).
So this 78cm wide shell is young for a Tridacna, but already impressive on a cofee table...It has been polished inside and slightly outside. Unlike today's Giant Clam species Tridacna gigantea is not a protected species. It is an extinct species.
