Busycon carica Gastropod
SITE LOCATION: Probably James City Formation; found Aurora, North Carolina, USA
TIME PERIOD: Lower Pleistocene (2.588 ± 0.005 and 0.781 ± 0.005 million years ago)
Data: The knobbed whelk (Busycon carica) is a species of very large predatory sea snail, or in the USA, a whelk, a marine gastropod mollusk in the family Busyconidae, the busycon whelks. The knobbed whelk is the second largest species of busycon whelk, ranging in size up to 12 in (305 mm). Knobbed whelks are native to the North Atlantic coast of North America from Cape Cod, Massachusetts to northern Florida. This species is common along the Georgia coast. It is the state shell of New Jersey and Georgia. The shell of most knobbed whelks is dextral, meaning that it is right-handed. If the shell is held in front of the viewer, with the spiral end up and the opening facing the viewer, the opening will be on the animal's right side. The shell is thick and strong and has six clockwise coils. The surface is sculpted with fine striations and there is a ring of knob-like projections protruding from the widest part of the coil. The color is ivory or pale gray, and the large aperture (the inside of the opening) is orange. The canal inside is wide and the entrance can be closed by a horny oval operculum.
