Could be - it is really hard to tell from a picture. Looks like it could have a little fusion crusting.
First thing is - is it heavier than it should be for its size? That's a biggie. I know the second thing everyone asks is - is it magnetic, and, 95% of meteorites ARE magnetic - but not all. We have one that has so much nickel in it that it went through several experts before we finally had it verified. And, a regular magnet will not tell the tale. You need something in the caliber of a rare earth magnet, as the very least. Ours does have a tiny magnetic spot - about the size of a pencil eraser - the rest - nothing. And, it doesn't have to "snap" to the magnet, either - it merely has to make a magnet on a string move towards it.
Best way to find out is to take off a bit - some suggest a small file - or something similar. What you are looking for is little flaky marks, inside, and probably a different color. Look with a magnifying glass, and look from 40 different directions, because they are hard to see sometimes.
Here is a good informative site:

If you decide it is worth finding out professionaly - watch out who you send it to. Some won't send it back to you, some want a part of it, some are just not always right.
Make sure you send it to someone who will return your piece and maybe charge you a flat fee. When we found ours, the University in Arizona used to do it (they did ours on the third time around) - but I am told that they are no longer doing it.
What's neat about some of these professional places is, they can tell if its a meteorite, and, they can usually tell you what meteor it came from, and how old it is. If you are real lucky, it could be a "new" meteorite - and the value there goes up for the labs that need them for their databases.
(they don't need the whole thing, just a little slice to match composition and the patterns inside).
