Looks like ribbon grain in photos 2-4, so Sapele or Iroko are both possible candidates. Be nice if it was Brazilian Mahogany, but that's veering towards the "all our geese are swans" trap. If it's a pig to plane without tear out then Sapele would be my guess (in which case have three weetabix and try a close set cap iron, it's real work on a board that size but it'll get the job done).
If you can do a bit of re-sawing then you've got just enough to make one of these,

Personally I think a project similar to that should be on every home woodworker's list of objectives, it's a useful piece of furniture that will find a place in most homes, and it's a good test of wide range of basic woodworking skills.
Good luck!
