Many Dinosaur Park formation fossils

[Joy_Fossils]

Hi everyone! 
 

We recently went on our first trip to the Dinosaur Park formation in Alberta. These are some of the fossils we found and need help identifying. There are 6 fossils we need help identifying, so instead of making 6 different posts I thought I would just make one long one!

 

Here is the first fossil:

We think it’s part of a turtle, but it is different from the other pieces we found that day. One side of the fossil has a lot of bumps and the other has a small ridge. Any ideas?

The next one we have absolutely no idea what it could be. It is a rather small piece of bone. We are not even sure if it is dinosaur bone or something else. It has an interesting shape.

This is the biggest piece we found that day. We were thinking a part of a vertebrae process, but weren’t too sure.

The next one is a piece with a texture that we have never seen before. It is much smoother than what we usually found. Any idea what it could be?

The next one is another piece with that interesting texture. The interesting thing with this one is that it has some long marks running along the surface that don’t seem like they are part of the bone texture. I thought they could be scavenger marks, but I was also told they could be bug burrows. Thoughts?

The last one is this fossil. It has pretty interesting texture and shape. I have absolutely no clue what this could be.
