Lateral view of the right maxilla of Eudimorphodon cromptonellus (MGUH VP 3393), new species. fewer than the number reconstructed for the Milano juvenile (Wild, 1978, figs. 25, 27). Postcranial Skeleton Vertebrae. Approximately six cervical, eight dorsal, one Psacral, and one (possibly two) caudal vertebrae are represented. However, postmortem disturbance consid- erably obscures vertebral details. Although some vertebrae are more or less associated in a series, inost are disarticulated from one another. Furthermore, in most cases the neural arches and centra themselves are disarticulated; the only complete ver- tebra is an elongate midcaudal (Fig. 3; centrum length min; overall length, mm). Reconstruction is further hampered by the overlap of bones that have collapsed one on the other. Of the eight isolated cen- tra that appear undistorted and are suffi- ciently exposed for measurement, all are of uniform length (— mm). The most complete neural arch (Fig. 3), which is isolated, is mm in length (including the small pre- and postzygapophyses), lacks transverse processes, has a neural ca- nal width of inin, and has a spinous process height of inm. The arch's lack of transverse processes and relatively re- stricted neural canal, considered with its proximity to the hind foot and a midcaudal vertebra, are evidence that the element is derived from the proximal caudal series. Two neural arches (also separated from their respective centra; Fig. 2) are inter- preted as representing dorsal vertebrae by virtue of their association with elements of the shoulder girdle and the presence of transverse processes (approximately 1 mm in length) that project horizontally from the jvmction of the laminae and pedicles. The breadth of the neural canal is mm in the smaller, and mm in the larger speci
