Gigantism and acromegaly are two disorders with the same disease mechanism and somewhat similar presentations. Even though they have the same disease mechanism, the two have entirely different outcome simply due to the age of onset. Gigantism is the result if the disease mechanism starts in childhood.
Adult Velociraptors grew up to 6.8 feet (2 meters) long, 1.6 feet (0.5 meter) tall at the hip and weighed up to 33 pounds (15 kilograms).
Scientific reconstructions of this shark estimate the dorsal fin 5.5 feet tall, the pectoral fins at 10 feet in length and the tail over 12 feet high. If you were unfortunate enough to have a Megalodon shark swim over you, the pectoral fins would measure 30 feet from tip to tip with a torso in excess of 10 feet thick! The jaws were so large that this shark would be able to swallow a Rhinoceros whole.
