Reptile Skeletons

Do reptiles have bones or cartilages?
Arethe reptile's skeleton made of bones or cartilages?
Another one please...
Would you say that mammals have either - hair/skin/fur - or all of them?
Reptiles' skeletons are made of bones. Cartilaginous fish are the only vertebrates that have skeletons made entirely of cartilage. I would say that mammals have hair, skin, and fur; all of them. Hair and fur are practically the same thing, and all animals have skin.
