Dear Sheila,
Many thanks for your comment! We have considered this option, but if this
was the case and this individual retained the Pd2, could it have a permanent
(one cusp) P3 and a deciduous (two cusps) Pd4? Then there is also bone
fusion is more cosistent with an older individual (e.g., pelvic symphysis is
almost fullly fused)....
All the best,
Mariana
