A couple of years ago I gave $2 for a box of wood at a garage sale. I've used most of it but there are some pieces of prefinished Oak trim left. It was stained a deep red on one side. I looked at it and the grain was different, much darker than any oak I've seen. I cut it up in small pieces to make it usable and glued three pieces together to turn on my lathe. I'm puzzled at the dark grain in this wood. If it is Oak, I've never seen this type before. Unfortunately, the rest of the Oak I have is normal Oak.

Any ideas of the type Oak this is?

I have seen similar grain patterns in limb wood where the grain is curved as the limb bows. I used some a few years ago but found it to be very unstable. It tended to twist and bow on me. I think it is because the wood on the bottom of the limb gets compressed and tends to want to straighten when it is out of compression. At least that is my theory. 

I was told one that there are 600 some species of oak

Red Oak has open pores, White Oak has closed pores or no pores.

Holy cow!! 600! No wonder I'v never seen this type before. Now I have 496 other Oak species to look for

Looks a bit like Chestnut oak also known as American chestnut. Wonder if it has spalted?

Doesn't look like oak.  I want to say some kind of exotic. I've seen garbage wood ( imported made somewhere else) furniture wood with a grain like that only lighter in color ( almost completely blonde) but that might be old growth for that type of wood.
