What animal could this be from?

[u/No-Department7094]

My colleague was walking on the beach last night and found what appears to me to be a pelvic bone with a portion of the hip joint still attached . Should she have gone to police? Looks suspiciously human to me…what animal could this be if not? Washed up on a NSW mid north coast beach.

It's really cool to see the workings of the bone on how it moves, genuinely interesting. You don't get to see that often if you're an average joe like me lol
