Fig. 29 Baryonyx walkeri, holotype, BMNH R9951; isolated dorsal ribs; A, B. anterior; C, D, mid-dorsals; E, F, posterior, x vertebra are united by a bridge, producing a saddle-siiaped proximal end. The paired anterior processes found in Dilophosaiirus and Allosaurus are altogether absent here, in which respect Baryonyx resembles Ceratosaurus. The distal portion of the bone, beyond the point of union of the two sides, is transversely flattened and ex- panded into a blade-like structure with a straight anteroventral margin and a concave posterodorsal margin. Sternum (Fig. 3IC) A fragile plate of bone, in some places no more than 1 mm thick, has broken edges nearly everywhere. However, it is strongly ridged like a tile from the ridge of a pitched roof, with two smooth surfaces lying at an angle of some 40° to one another, suggesting that the fragment is a single median element with a median angulation. At what appears to be its anterior end the bone is considerably thickened; each half has a convexly curved anterior termination, and between the two is a median embay ment. Part of the right-hand edge is a true margin which runs diagonally to the midline, thereby indicating that the bone originally widened rapidly towards its thickened posterior end. B.
