Cephalopoda is the scientific name for the mollusc group that includes the chambered Nautilus, squid, and octopus. Two extinct types are found at the C & D canal: the Nautilus-like ammonites and the superficially squid-like belemnites. Ammonites are uncommon, especially complete specimens, but can be very useful for age determination.

The reason for this difference is the natural structure of gastropod shells, which are undivided from the interior and have a spiral shape.gastropod. Gastropod - Mollusks, Shells, Foot: The basic foot form in gastropods is a flat, broadly tapered, muscular organ. A series of paired ganglia are connected by nerve cords; chemoreceptors are scattered over the skin surface. Warning and camouflage coloration are used as defense. Fossil gastropods are known from Cambrian deposits.

Inside the shell, scallops have a white adductor muscle (the part we eat) that opens and closes the shell, as well as a bright orange section called the coral. The muscle is round and tender when cooked, with ...The interpretation of Fordilla as a pelecypod was based on articulated material and internal molds that show pelecypod muscle scars. Subsequently, teeth and ligament groove fillings have been found (Pojeta, 1978). Subsequent workers accepted Fordilla as a pelecypod, documented the constancy of the muscle scar patterns, provided data aboutOn page 148-149 is a pelecypod called Lyriopecten orbiculatus whose description is "Roughly circular shell with short hinge line, very small to absent anterior ear, and small posterior wing.
