Why is a Pterodactyl called a Pterodactyl?




The name means 'wing-finger'.



Bird wings are supported on 'arm bones'.

The outer part of bat wings are supported on finger bones.

The outer part of the wings of pterodactyls and other pterosaurs are supported on long 'little finger' bones.

One well-known larger pterosaur is Pteranodon.
