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).
As far as physical differences go we all know the male/female anatomy is different. Usually males will be a little larger than the females but only about 1 to 2 inches in height and 3 to 5 pounds heavier. But, this is not always true, our Striker is just 14 lbs., Bo weighs 16 lbs & both Raptor & Lync weigh 18lbs. I have some females that weigh close to 20 lbs.
