Need help identifying these species of wood

[raffo]

I'm trying to identify the species of wood that this stump came from. The pictures I took are at

for the first stump, I'm clueless. But I do know that it's very heavy, as I had one heck of a time trying to pick it up and load it into my SUV - multiple tries.

As for the last picture, I'm pretty sure it is of an Oak stump, but not

100% sure.

Thanks
