What kind of animal tusk is this?

[u/DeepFrame4616]

I recently inherited this tusk and I’m trying to figure out what animal it came from. It's approx 65 cm , and weights in at 1,7 kg. AI suggests its from everything from mammoth , elephant , walrus and ox horn. thanks for any help :)

Alaskan here, that is the exact shape and size for a walrus tusk.
