  1. Morphometric data of O. medius (Samples B6, 8 and 9) from the upper Campanian of Oman and O. ‘medius’ from the upper Maastrichtian of Beyobası Formation (sample 16–20) are given for comparison purposes. N denotes the number of specimens. Li + li: size of the embryon, E: total number of epi-embryonic chamberlets (see Fig. 6)
