Its identifiably different Jens by the angles of intersection of the cross hatching. {Schreger lines.}

Usualy Elephant is nearer 90 degrees & mammoth nearer 115 degrees in the outer areas of tusk.

But if several angle measuments are taken of any ivory piece in questian all elephant samples have averages above 100 degrees, and all the extinct proboscideans or {mammoths}have angle averages below 100 degrees.

Also Siberian Mamoth ivory is heavier & harder than Elephant ivory. i dont know about other sources of mammoth but they I am aware they are not usualy of the high quality of the Siberian material.

I think Mammoth ivory has been used on South East Asian pieces before & there was also a big market in Europe in it pre. 1900 with parcels of up to 20 tons auctioned at a time in Liverpool ,Antwerp & London. So I expect it could turn up anywhere.
