Hello,

Does anyone have some references for papers by Dr. Eberhard Frey from the 
Museum of Natural History in Karlsruhe, Germany? I understand he has been 
undertaking an extensive research on crocodile's sexual anatomy. He found 
out that it was possible to distinguish male from female crocodile simply 
by their skeletons (a common cloaca but an 'intromittent organ' for the
male with special retractor muscles that are reflected on the skeleton).

I would like to read about it. Thanks.

Emmanuelle.
