Found a Bone on Vacation, Can Anyone ID the Species it Came From?

Took a trip to northern Vermont last week and while I was throwing sticks to my dog I found a bone half buried in a creek bed. I was thinking it may be a bears bone, it's very dense/heavy and about the size of my upper arm (I'm a full grown man). Being from Philadelphia I'm not used to running into any large animal remains so I'm just curious if there is anyone that could shed some light on it. I looked around for more pieces but couldn't find any, but there was a rock cliff across the creek from where I found it that looked like it frequently lost a lot of rocks down the hill and into the creek bed, so maybe it came from there. I was in deep woods in the Green mountains. very dense and far away from anything I would consider a town. Also, I plan on sinking it in my tank eventually so if anybody has a decent way to get it back to white without using chemicals I would be very appreciative.

Looks like a bear's tibia. The distal tibiofibular joint prominence is still intact (the bone closest to your elbow - which is part of the ankle). The lateral condyle (outside of the lower knee) is showing signs of erosion or sampling by scavengers.

That's awesome. I really appreciate it Oddball. One of the locals we talked to later said it could have been a cow, but that didn't really jive with the rocky, wooded, kind of mountainous area I found it in. I thought bear from the jump as well and it would definitely make sense.

On a side note my 6 year old son is still 100% sure it was a T-Rex, so Im just going to let him have it. We had a blast searching for fossils after I picked it up, can't take the Dino hunt from him.

I found out the best way to clean the bone is hydrogen peroxide. After it's soaked and whitens up it's rinsed and cleaned completely with water and dried. Do you think it would remain toxic after the drying process? It's probably best not to put it in the tank, and I probably won't unless someone knows the science and can tell me otherwise.

You can pour straight hydrogen peroxide into your aquarium to add O2 in an emergency (power failure). So, the H2O2 isn't toxic. If you're worried about the bone, ...once bleached it may be coated with a clear epoxy to seal it completely. Once the epoxy has cured it's components will be inert.
