Dear Marmamers,

I need some help to assemble a pectoral fin of a killer whale (Orcinus orca). I have all bones of the pectoral fin, but we don't know how they are positioned. I searched in some books and in internet, but I just found pectoral fin of other species and I am still on doubt in many aspects. If someone can help me in someway, sending a photo or an image of this species by which I can rely on to build the sequence of bones, or in another way, I will be thankful.

Thank you.

Regards, 

Bianca
