Dear Zooarchers,

I have a question regarding sexing the tiger pelvis. I identified an ancient tiger skeleton in western China which has complete pelvis, and now I want to know its sex. In my lab, there is also a complete tiger skeleton but we don't know its sex either. Based on the morphology of the tiger pelvis of our lab, I guess it's a male, because the angle between the two pubis and ischium bones are very sharp and narrow, also, the lliopubic eminence is not sharply developed. Based on the picture of the pelvis of the ancient tiger I took in the field, I guess it's also a male, although I am not sure whether it also has sharp angle between the pubis because the two parts of the pelvis fall apart in the site. 

Do anyone has some ideas about sexing the tiger pelvis? I have uploaded the pictures of both the modern and ancient tiger pelvis.
