Bird and Pterosaur Feet (3)

It would appear that in the transition from rhamphorhynchoid to pterodactyl the fifth digit of the hindlimb was lost.
Page 302:
"Pterodactyloid pterosaurs however do not have a fifth digit...."
Page 303:
"The two middle toes of a pterosaur are longer than the two outer ones."
"The inner three claw impressions curve and are inclined sharply outwards and the outer one curves and is inclined slightly inwards."
