See Russell, A.P. and Bauer, A.M., 1992 - The m. caudifemoralis longus and
its relationship to caudal autotomy and locomotion in lizards (Reptilia:
Sauria), J. Zool. Lond. 227: 127-143.

hindlimb in lizard locomotion, The American Journal of Anatomy 95: 1-40.

BYT: After reading these you'll understand why pterosaurs are fundamentally
