![]() ![]() In fact, the ostrich’s skeleton makes up less than 10% of its overall body weight, while a T-Rex skeleton makes up at least 20% of its overall body weight, if not far more. ![]() Given the fact that the T-Rex doesn’t have as many hollow bones as the ostrich means that the skeleton of the T-Rex is much heavier when compared to the overall body weight of this dinosaur, which is not the case with the ostrich. But how exactly does this make a difference in the skeletal structure of both the T-Rex and the ostrich? However, the ostrich has more hollow bones compared to the average T-Rex. Both ostriches and T-Rexes have hollow bones, at least to some extent. Scientists have often believed that T-Rexes are the ancestors of modern birds because of their bone composition. Ostrich Skeleton vs T-Rex: Bone Composition The ostrich’s skeleton makes up less than 10% of its overall body weight, while a T-Rex skeleton makes up at least 20% of its overall body weight, if not far more. However, the neck of the T-Rex isn’t nearly as long as the neck of the ostrich, and the overall size of the average T-Rex has much to do with the length of their tail, something that the ostrich does not share. It is also interesting to note that the ostrich earns its height from its legs and neck, while the T-Rex also has extraordinarily long legs compared to its family of dinosaurs. For example, the average T-Rex skeleton measures 12 to 15 feet tall from the hip bone, while the average ostrich measures 6 to 9 feet tall, including their very long necks. While the ostrich is one of the largest flightless birds in the world, the T-Rex is significantly larger in every way. One of the primary differences between the T-Rex skeleton and the ostrich skeleton has to be the sheer size of the T-Rex. Ostrich Skeleton vs T-Rex: Size The average T-Rex skeleton measures 12 to 15 feet tall from the hip bone, while the average ostrich measures 6 to 9 feet tall, including their very long necks. ![]() Let’s continue our comparison in more detail now. Additionally, the skeletal structure of the ostrich is much lighter than the skeletal structure of the T-Rex, though both of these creatures have hollow bones.īut this is only the beginning in terms of the similarities and differences between these two creatures. While they may have a similar shape upon first glance, the ostrich skeleton only measures 6 to 9 feet tall, while the T-Rex skeleton measures 12 to 15 feet tall. There are a number of differences between an ostrich skeleton and a T-Rex skeleton. Key Differences Between Ostrich Skeleton vs T-Rex The skeletal structure of the ostrich is much lighter than the skeletal structure of the T-Rex. Large eye holes and narrow skull for seeing well Huge skull with multiple openings in bones to reduce weight, as well as some pneumatic bones. Large eye holes and mostly pneumatic bones (full of tiny holes) Possibly, but only on certain sections of the bodyĮxtremely small and pyramid or triangular in shape. Yes, on main part of body and some down on their heads The longest legs compared to body size of any other theropod, with three toes Small clawed arms and hands hardly useful, given the size of the average T-Rex. Legs range in length and end in three sharp toes Small wings, with a wingspan of 5-7 feet across incapable of flight.
