The synsacrum is a skeletal structure of birds and other dinosaurs, in which the sacrum is extended by incorporation of additional fused or partially fused caudal or lumbar vertebrae. This structure can only be seen in birds. Some posterior thoracic vertebrae, the lumbar, sacral and a few anterior caudal vertebrae are fused to form a complex ...

The skeleton consists of very lightweight bones. They have large air-filled cavities (called pneumatic cavities) which connect with the respiratory system. [77] The skull bones in adults are fused and do not show cranial sutures. [78] The orbital cavities that house the eyeballs are large and separated from each other by a bony septum (partition).
