Answer 2

The turtle shell is made up of numerous bony elements, generally named after similar bones in other vertebrates, and a series of keratinous scutes which are also uniquely named. ... As such the carapace is made up of 8 pleurals on each side, these are a combination of the ribs and fused dermal bone.
