Fig. 12. Artificially articulated anterior cervical series of IGM 100/1803 illustrating the relative length increase between vertebrae. The ansa costo-transversaria is reconstructed on the sixth vertebra. Note that all cervical ribs in this figure are incomplete; preserved ribs overlap at least one succeeding centrum, but have not been reattached due to their fragile nature. The hypothesized position of M. ascendens cervicalis shown in white, with small arrows indicating attachment sites (after Wedel and Sanders, 2002: fig 2). Scale bar 5 50 cm.
