Extraordinary flexible shell sculpture: The structure and formation of calcified periostracal lamellae in Lucina pensylvanica (Bivalvia: Lucinidae)

Mostrar todas las versiones(3)

The lucinid bivalve Lucina pensylvanica possesses an unusual flexible commarginal shell sculpture formed from calcified periostracal lamellae. The lamellae comprise thick, recurved, periostracal extensions with distal calcified scales. The periostracum is also densely embedded with calcareous granul...
