while they are very small in comparison to limbed reptiles, the hind limbs of "eupodophis" possess much of the same anatomy as modern lizards. this suggests that the bones of "eupodophis" became reduced in size through a change in the rate of bone growth, not major anatomical changes. the lack of thickening at either end of the limb bones suggests that growth had stopped occurring in the limbs at one point in the animal's lifetime. while the vertebrae and ribs of "eupodophis" are pachyostotic and osteosclerotic (meaning that the outer and inner parts of the bone are compact), the limb bones remain light. this lightness is also seen in the bones of terrestrial lizards, suggesting that the limbs had not been part of the overall adaptation of the skeleton for an aquatic lifestyle.
