Singular Squatina tooth which are approximately 153 million years old and were collected within the Cymodoce Zone of the Kimmeridge Clay Formation, Weymouth, Dorset. Squatina are a genus of shark also referred to as monkfish or angelsharks. They have a flattened form and were well adapted ambush predators which lay dormant and camouflaged just beneath the sediment surface awaiting passing prey. Monkfish feed on primarily small bony fish but their diet is quite diverse and they do eat small mollusks and crustaceans also. They have powerful jaws lined with small sharp teeth which help grip onto slippery food items. These teeth are sold separately and naturally vary in size between 1 and 2 mm. Individual teeth are supplied in a small plastic bag with an information label.
