Dinosaur bones, fossil, or just a strange rock?

[MilitariaCollector]

I found these in a creek in NJ that alot of fossils have been found in. I think they are some kind of bones. I thought the smallest one was just a rock, but I never have really seen any rocks with a hole in the middle. Looks very strange. Any ideas?

These are what are commonly known as concreations. Not fossils. http://www.njfossils.net/DVC02568.JPG

Definitely look like iron concretions. They are common in at least one nj fossil collecting stream.
