The straight line distance from the ventral-most margin of the articular tubercle to the ventral-most point of the sternal end of the rib (McCown & Keith, 1939: fig. 75) is roughly 72mm, while the maximum subtense from this line to the lateral-most extent of the rib shaft (ibid.) is ca. 25mm. Abundant cutmarks can be seen on the superior surface in the region of the proximal attachment area for M. scalenus medius (the cutmarks extend along the internal edge from the neck to the level of the distal tubercle). Cutmarks can also be seen on the superior proximal and distal sides of the tubercle, which may reflect cutting of the lateral costotransverse ligament. There is some slight weathering to the distal superior surface of the shaft. The ligamentous part of the tuberosity is neither rugose nor large. The crest for M. scalenus medius along the superior proximal surface of the shaft is insignificant and non-rugose. There is a small crest on the external edge of the rib distal of the tubercle that may represent the lateral limit of this muscle. There are no other visible muscle markings on the bone. There is no perceptible scalene tubercle, so the grooves for the subclavian artery/1st thoracic nerve and subclavian vein run together into one shallow, poorly delimited sulcus. RIB 2 Right: (GC 87 220) Left: (GC 87 132) Both second ribs are represented by fragments. The right second rib preserves a part of the head, the tubercle and the proximal shaft up to but not including the attachment area for M. serratus posterior superior (and extending further on the internal side). The total length of this fragment is Most of the head is missing or eroded. The partial preservation of the head allows for a rough estimate of neck len
