Looks like Marula to me. The pod fits, with it's size, shape and double seed holes. The cotyledon shape fits. The leaves look a bit blurry in the pics, but though I can't get a good look at the petiole & specific leaf type, the general shape reminds me of it as well.
If it really is Marula, re-plant the pod. I got two plants out of mine. It's really more of a double-seeded stone than a single seed.
