). In rostral view, the body of the bone is high, especially along its medial margin. The ascending process is long, and it is inclined medially. A small process for the prefrontal connection occurs medially at its distal termination. A ridge extends from the base of the ascending process as far as its distal termination. A large, slightly oval, foramen occurs opposite to the medially directed maxillary-prefrontal process. In caudal view, a wide groove for connection with the ectopterygoid occurs above the base of the fangs. This groove is deep, and it is restricted dorsally by a transverse ridge. This ridge extends from the medial margin of the bone (where it forms two small processes) as far as the middle of the ascending process width. In medial view an oval foramen occurs within the deep, wide orifice. This orifice is restricted dorsally by a ridge.

The most complete neural spine lacks its cranial margin, but it seems possible that it was vertical or slightly anteriorly inclined. The interzygapophyseal ridges are welldeveloped and sometimes rather sharp. Lateral foramina are large and are situated in shallow depressions. The parapophyses are well-separated from the diapophyses and the parapophyseal processes are strongly built and directed antero-ventrally. The subcentral ridges are conspicuous. The condyle is developed on a very short neck. The rarely preserved hypapophyses of anterior trunk vertebrae are long, straight, and directed posteroventrally. The pointed distal termination of the hypapophysis of middle and posterior trunk vertebrae is directed caudally. The hypapophysis of the posteriormost trunk vertebrae have indication of bifurcation on its distal tip. In dorsal view, the vertebrae are markedly short and wide. The cranial margin of the zygosphenal lip is concave, straight, or with a small medial lobe. The medial lobe is better developed in posterior trunk vertebrae. The prezygapophyseal articular facets are widely oval to subtriangular (although partial damage cannot be excluded). The prezygapophyseal processes are broken-off close to their bases. Epizygapophyseal spines are absent. In ventral view, the subcentral grooves are shallow, and the large subcentral foramina are situated on both sides of the base of the wide hypapophysis. The ventromedial margin of parapophyseal processes is always medially enlarged and it is usually fused with the ventrolateral extensions of the cotylar rim (subcotylar tubercles). The blood vessels of the circulatory system passed through the canals on both sides of the hypapophyseal base. The postzygapophyseal articular facets have an irregularly triangular outline. In cranial view, the neural arch is strongly flattened dorsoventrally. The cranial margin of the zygosphene is straight. The prezygapophyses are tilted up dorsally. The paracotylar foramina are situated on both sides of the rounded cotyle. The subcotylar tubercles are usually fused with bases of parapophyseal processes. The vertebral dimensions of the largest vertebrae from 1/2001 Turtle Joint are as follows (n = 7): cl: or =
