Megalosaurus thigh bone
A human thigh-bone figured as item 4 on TAB VIII by Dr. R Plot in The Natural History of Oxfordshire in 1677 is actually a dinosaur thigh-bone, probably Megalosaurus

Skeletal reconstruction of Albertosaurus showing the hind leg and foot. The upper foot bones of this Albertosaurus are locked together for strength, perhaps to withstand the stresses of running

Iguanodon leg
A model cross section of an Iguanodon leg showing the bones, muscles and foot. The Iguanodon was a mainly a bipedal dinosaur. It required large upper thigh muscles for balance and support
