Cherrie D. Bramwell 
Cherrie Bramwell teamed up with the aeronautical engineer G. R. Whitfield to work on the flight mechanics of Pteranodon. in 1969. Their work is a classic on the flight dynamics of this amazing vertebrate. This work was an extension of her interest in flight and her intensive study of bats.
