Shell-bearing Bivalvia and Gastropoda from a rocky shore in the Central Caribbean of Colombia.

This study documents the natural accumulation of mollusk shells on an elevated rocky shore carved into the calcareous rocks of the La Popa formation at Punta Roca (Atlántico), covering an estimated area of 0.35 km. Hydrodynamic transport and differential exposure to environmental conditions are the primary factors contributing to shell deposition.
