Adult or Juvenile Size?

Instead of a wonderful work of art this week, we will end this week with a size comparison of Siats and Siats. The fossil remains of Siats that have been discovered and analyzed indicate an animal approximately the size of the darker shaded version of Siats in the image here. The estimated size of Siats, as we can see here, is around 9 m long and 2.5 m tall at the hips. If this theropod was indeed a juvenile, the estimated full grown size of Siats would have been slightly larger than a Tyrannosaurus at 12 m long and 3.5 m tall at the hips. The largest known Tyrannosaurus, Sue at the Field Museum, is 12.3 m long and 3.66 m tall at the hips. The largest estimation for Tyrannosaurus is approximately 13 m long, only slightly larger than Sue or the estimation of an adult Siats.
