Strange Cretaceous Orectolobiformes?

[fossilsonwheels]

I found this tooth several years ago while searching micro matrix from Colorado, which I am now certain is Mancos Shale. 

 

Never mind. Mystery solved. Lesson learned=I need to wear my glasses when trying to ID teeth from pictures lol It’s a Catshark or something similar.

I wear my glasses all the time. Sometimes they don't help.

It is a little tough to tell for sure from the pictures, but the root of the tooth looks more like that of a sandtiger intermediate or  symphyseal tooth than a catshark tooth.

Hi Marco Sr

 

I think you could be right. The root is not very Catshark like. I’ll try to take clearer pictures this week. I’ve got a few teeth from this formation that I need better ID’s on. 

I could use your opinion on this one too. I’m pretty stumped on what it could be. I originally thought sawfish rostral but I’m not sure about that. I have found a couple of Cretomanta in this so I’m leaning toward that though the other two looked a little different. I kinda of thought it looked similar to Pararhincodon but I am pretty sure that is wishful thinking lol

It’s tiny, under 2mm. 

 

Any ideas ? I know the pictures aren’t great.

Here’s another I need better photographs of. I think it’s Orectolobiformes but  I’m really not sure what it is.  Very small at 2mm or so. It’s a strange one.

The root of this specimen is eroded, which makes an ID very difficult.  The root sits on top of the crown like that of a Cretomanta tooth, but the crown of this specimen is too flattened and compressed to be Cretomanta.  Below are pictures (I picked these to highlight the shape of the crowns) of two Cretomanta teeth (1 mm and 1.5 mm) from the Cretaceous of Kansas.

 

 

 

 

 

The crown also isn't right for Pararhincodon which flare out by the base and are very small, 1.2 mm maximum size and are found in the Campanian (I don't know the age of the matrix that this specimen came from) according to Welton 1993.

 

I really can't ID this specimen  because of the eroded root.
