Some chompers in need of a solid ID

[Notidanodon]

Hi guys I have 2 teeth that I can’t id, Im posting 1now and the other later, this one is lutetian, 

Selsey sand  fm. Unit L4/5

Bracklesham group, from lee on solent

[butchndad]

i'm far (farthest) from an expert but it looks like a anterior Goblin shark based on the heavy striation and the pronounced nutrient groove.  If i'm actually correct i will buy myself a beer!

[Notidanodon]

Now from big brook

1.scaphanorhynchus texanus?

2.no idea cretoxyrhina?

3.cretolamna?

4.chimmaerroid mouth piece? Is a species id possible

5. Not sure which species of squalicorax

I believe its an odontaspidae, also i dont know much about common names, but isnt a goblin shark scaphanorhynchus, which is cretaceous and therefore the wrong age?

maybe @Al Dente could help identifying it

From big brook, 1. Are goblin shark teeth, 2. Is an archaeolamna kopingensis tooth, 3. Are cretalamna appendiculata teeth, 4. Looks like a ray plate to me, but I couldn’t I.D it’s exact species if it is, and 5. I think they’re pristodontus, but I’d wait for a couple more experienced members see.

2 – Is it from Big Brook? Looks like Archaeolamna, but wait for confirmation from others.

3 – Cretolamna sp. (appendiculata is restricted to Upper Cenomanian and Turonian)

5 – Squalicorax kapui

[PaleoNoel]

First tooth from bracklesham looks like Striatolamia (sand tiger). As for the big brook teeth I would say all the goblins look like scapanorhynchus. I agree with @Praefectus for the rest, Archaeolamna, Cretolamna and S. kaupi/lindstromi.

2 is from big brook, i think it is sun bleached, is it possible to get it or the cretolamna down to a specis ID  thanks again for your help

Haha

 

on another note @Praefectus could the archeolamna maybe be a.kopingensis

[Praefectus]

Sorry for the slow reply. I've been busy organizing the next TFF rolling auction (check it out).

 

A. kopingensis appears to be a match. I am not super familiar with Archaeolamna species identification. 

 

As for Cretolamna sp., Big brook is Campanian-Maastrichtian (I think?). Based on that, C. sarcoportheta, C. borealis, and C. arambourgi are all possibilities. I would have to read through the scientific literature again to give a species ID. 

 

Here is the link to the article the revised Cretolamna.
