What type of bone is the pygostyle?
The pygostyle is a part of the axial skeleton of the bird. It is a flat bone created by the fusion of the final few caudal vertebrae into a single ossification. – It serves as the attachment site for tail feathers as well as muscles, thus providing flight stabilization.

What is Synsacrum and pygostyle?
The synsacrum is a unit formed by the fusion of the posterior thoracic, lumbar, and sacral vertebrae. … Birds also have a pygostyle, which is a flat bone created by the fusion of several vertebrae at the end of the column. It serves as an attachment site for tail feathers, which contribute to stabilization during flight.
Which group of dinosaurs also has a Pygostyle?
