Busycon is a genus of very large edible sea snails, marine gastropod mollusks, in the family Buccinidae. These snails are commonly known in the U.S. as whelks or Busycon whelks. Busycon comes from the Greek: bous meaning cow and sykon meaning fig; translating to large fig. This is one of the few genera of gastropods in which the shell may coil either to the right or the left. These fossils date to the Cretaceous Period of the Mesozoic Era (65 million to 136 million years ago)...

Turritella Molds and Leperditia Molds Turritella molds are the corkscrew like cavities. This species was a cephalopod that crawled along the bottom of the sea looking for bits of food. These organisms would have lived in the Triassic period (with the early dinosaurs) making them 190 million to 225 million years old. Leperditia molds look clam like but are crustaceans distantly related to lobsters, crabs and barnacles. The organism would be similar to a shrimp with antennae and several small ...

The whale ear has specific adaptations to the marine environment. In humans, the middle ear works as an impedance matcher between the outside air's low impedance and the cochlear fluid's high impedance. However, in aquatic mammals, such as whales, there is no great difference between the outer and inner environments. Instead of sound passing through the outer ear to the middle ear, whales receive sound through the throat, from which it passes through a low-impedance fat-filled cavity to the inne...

Ecphora is a close, extinct relative of Morex, and may have shared the same feeding habits. If so, Ecphora would have been a predator, boring holes in the shells of bivalves or other snails. A gland at the foot would have secreted a special chemical to soften the prey’s shell. A set of tiny teeth, called the radula, would have rasped first the shell and then the victim’s flesh. This example is of good quality with the tip worn down. Found: located at Eden Estates Pond, King George County, Vi...

Fine and detailed example of a fossilized whale vertebral epiphysis (growth plate). All mammals have growth plates at the end of long bones while in juvenile stage to incorporate growth. Once adulthood is reached the growth plate is absorbed stopping further growth. This whale died as a juvenile and the growth plate slipped off the long bone. Age: 5 million to 25 million years old. Species: Megaptera species (?). Found in the Mid-Atlantic coastal region of the U.S.

Rare juvenile fossilized porpoise vertebra. This particular example demonstrates a lumbar vertebra of a porpoise with epiphysis (growth plate) on both sides indicating it was a juvenile. It is rare to see both epiphysis as they easily slip off the vertebra. The opening in the spinous process is to allow for the spinal cord. The two transverse process have deteriorated. Overall measurement: 3.5 inches long by 2.25 inches wide by 1 inch thick. The superfamily is Delphinoidea and the family is Phoc...
