Abstract

Flatfish in the Minas Basin, Bay of Fundy, produce feeding pits 3-5 cm deep and 2-3 cm in diameter when they strike downward at clam siphons and burrowing crustaceans. Pits are roughly triangular, truncate the bedding, and are often infilled with mud. These feeding pits have high preservation potential, and, if found in the fossil record, could be incorrectly interpreted. Fishes capable of making feeding pits are found as far back as the Devonian.
