Identifying horn species on a yatagan hilt

[ipostswords]

Thanks for your help everyone. I think ram seems to be the correct determination, it hadn't clicked ot me that the inlay was a rams head on the blade, but now I can't avoid seeing it.

I think the best way to check for sure would be to remove the handle scale and see if it has the "spaghetti stand" end grain, but I don't want to damage anything.

Even without checking the end grain, I am satified to say it's rams horn
