Some teeth

[Lorney]

I found a few different teeth this fall and was wondering if someone can help me identify them. I have an idea for some but I might also be way off. All found in Alberta in the Dinosaur Park Formation. Any info is much appreciated. 
 

Hadrosaur?? For this second picture

 

Ray tooth? Found 2’ away from the tooth in second picture. If it is a ray it must have been from an upper layer?? I think Bearpaw Formation above. If not a Ray do you know what?

 

croc scute and teeth??

 

Not sure about this one??

1. Indeterminate theropod, probably Gorgosaurus or Daspletosaurus.

2. Not sure if this is even a tooth, looks more like a turtle bone or something. More angles might help here.

3. Yep that's a ray tooth, the guitarfish Myledaphus. These are definitely present in the DPF, as most of the fossil bearing deposits are from river delta and lagoon systems.

4. Yep, crocs. I forget offhand which types are represented in the DPF, but you should be able to narrow it down somewhat with a bit of reading.

5. Hard to tell because of how worn it is, but looks sort of like an ankylosaurian tooth, with the root facing toward the right in your photo, and the crown to the left.

I was looking through a guide to Alberta Vertebrate fossils and came across this page on hadrosaur teeth. To me it kind of looks like the first tooth on the page. Maybe I’m wrong. Will attach a few more pics. Thank you for your help.

This one is not a hadrosaur tooth.  The drawing does not show the enamel they have.  This thing is likely some sort of skull fragment base on the striations, which are where it would have joined another bone.

I see thanks. Was just going off shape and size and it kind of looked similar to the pic. So the enamel would make it look dark and shiny like the other teeth??

Nice finds! The tyrannosaur tooth is great!

Need a straight in photo of this one but could be a Nodosaur tooth.  Agree with the other comments

Here are a few more pictures. One of each side. Finding it hard to get really clear pic of detail with it being so dark. Will try later with a desk lamp over it.

Yeah, and even when it is worn, it looks like the theropod tooth in your first picture.  Note the difference in texture/surface of the bone in question and that tooth.

Thanks everyone for your help. I am new to this so sharing your knowledge is much appreciated. Hopefully I can get to the point where I can contribute.
