Reaching lengths of up to 60-70 feet and an estimated maximum weight of over 60 tons, the Megalodon is the largest known predator in Earth's history. While most adult Megalodon teeth fell into the 4 or 5-inch size range, a few massive, fossil teeth have been found in excess of 7-inches. This replica is hand-cast and hand-finished, cast in super-strong Smooth-On resin for durability. The Megalodon Tooth comes with a Riker-Style box. Boxes are made of compressed hardboard with a textured surface coating, which include a clear glass window for showing off your fossil as well as a label to identify it. The tooth measures approximately 5 1/2-inches x 4-inches x 1-inch, while the box measures approximately 6 1/4-inches x 8 1/4-inches x 2-inches.
