Eupodophis years old. It was found in Cenomanian-age limestone near the al-Nammoura village in Lebanon. "Eupodophis" was a marine snake that lived in the Mediterranean Tethys Ocean. It had a laterally compressed body and short, paddle-like tail. The vertebrae and ribs of "Eupodophis" are pachyostotic, or thickened, as an adaptation to a marine lifestyle. The pelvic bones are small and weakly attached to each other. Tarsal bones are present but reduced in size and form. The metatarsals and phalanges of the foot are absent. The fossil skeleton of "Eupodophis" was analyzed using synchrotron x-rays at the European Synchrotron Radiation Facility in
Ostromia addition, the ungual (claw) of the first digit of the hand is smaller than the corresponding first metacarpal, while in "Archaeopteryx" the claw is larger. The Haarlem specimen's metatarsals are also estimated to be proportionally longer than those of "Archaeopteryx" specimens. In addition, the Haarlem specimen shares several features with "Anchiornis". Most notably, they both have longitudinal furrows on the top and bottom sides of their manual phalanges (finger bones). While such structures can be a result of collapsed or broken bones (as is the case in several "Archaeopteryx" specimens), the straight, smooth edges of the furrows in "Ostromia" and
