For each element, all sectioned specimens are listed in size order (in the order discussed in the text). All measurements are in millimeters. Abbreviations: ACT average cortical thickness, MajA major axis diameter, MCmaj medullary cavity diameter along the major axis, MCmin medullary cavity diameter along the minor axis, MinA minor axis diameter.
