Summary
| Description |
Left ilium (i.e. the left dorsal element of the pelvis) of Megalosaurus „from the Oolitic Slate, of Stonesfield, Oxfordshire“ (i.e. the Stonesfield Slate of the Taynton Limestone Formation, middle Bathonian), in lateral (Fig. 1) and ventral (Fig. 2) views. Note that in the original source (Owen, 1849–1884; see below) this bone was erroneously identified as coracoid, i.e. an element of the pectoral girdle – this is why the bone is shown turned by 90 degrees clockwise, i.e. its ‘upper’ end is actually the anterior (cranial) end and its ‘lower’ end is actually the posterior (caudal) end. Meaning of letters according to modern nomenclature: b = ischial peduncle, c = rim of preacetabular process of ilium, l = tip of postacetabular process of ilium (with pronounced brevis fossa on ventral side of postacetabular process), m = dorsal surface of acetabulum, n = preacetabular notch, o = pubic peduncle, s--s = dorsal rim of iliac blade. |
