the fossil skeleton of "eupodophis" was analyzed using synchrotron x-rays at the european synchrotron radiation facility in grenoble, france. the researchers determined that the hind limb on one skeleton was 0.8 inches long, with an "unmistakable" fibula, tibia and femur. one limb was visible on the surface of the fossil while the other was hidden within the limestone. the scans were compared with similar ones taken of the limbs of extant lizards including the gila monster, green iguana, and several species of monitor lizard.
