Hello!
Archaeopteryx is said to have a hypopubic cup.
Non-avian theropods, in turn, have pubic boots, even the dromaeosaurs which have
most retroverted pubes. Except Rahonavis, of course. I have read some opinions
according to which the differences between non-avian and avian dromaeosaurs
wouldn't be so clear-cut. Could you enlighten me?
Thanks in advance,
Henri Rönkkö
