It is an extinct giant shark, considered the largest shark in history and possibly the largest fish. Living during the Early Miocene to Pliocene period, approximately 23 to 2.6 million years ago. Fossil teeth are the main evidence for the existence of this ancient predator, and these teeth can grow up to 18 centimeters long, more than three times the size of modern great white shark teeth. It has a huge body size and a very strong biting force, making it the strongest known animal. The teeth are similar to modern great white sharks, with triangular, serrated edges and symmetry, but larger, thicker, more evenly spaced serrations, and a darker, V-shaped area near the root of the teeth.
