. A diapsid reptile from the Pennsylvanian of Kansas. Reptiles, Fossil -- Kansas; Paleontology -- Pennsylvanian; Paleontology -- Kansas. Fig. 8.—Petrolacosaiinis kanxctuis Lane. Mature skull, KUVP 9952. The e.\ternal (A) and internal (B) surfaces of the skull talilc and left cheek are shown, but the preserved part of the right cheek is exposed only in lateral view. See Fig. 2 for key to abbre\iations. (Fig. 12 and 13) a large shoet of bone tliat extends from the naris to the orbit. From its broad contribution to the narial border, the laterally exposed surface of the lacrimal ex- tends slightly upward, increasing its width posteriorly, and forming the anteroventral border of the orbit. Its suborbital ramus ex- tends far posteriorly and makes contact with the anterior end of the jugal. The ventral border of the lacrimal is overlapped by the maxilla from the region of the canines to the posterior tip of the bone, as seen in the right side of the skull in KUVP 33607. Conse- quently, less than half of the height of the suborbital ramus is seen in lateral view. The right lacrimal, in KUVP 33607, shows three foramina that open into the orbit. Two large lacrimal puncti are situated in a deep, conjunctival groove near the lateral border of the lacrimal. The groove is partially ex- posed in lateral view. A much smaller fora- men is visible on the medial surface of the suborbital ramus that may have carried the anterior orbital artery, much as in the primi-.
