The turtle shell is actually a peculiar evolution of a turtle’s bone structure.
Do amphibians have exoskeletons?

Do vertebrates have exoskeleton?
All vertebrates have an endoskeleton. However invertebrates can be divided again between those with an exoskeleton and those with a hydrostatic skeleton. Animals with endoskeletons have skeletons on the inside of their bodies.
