Theropod indet. from Niger

[BellamyBlake]

Hi everyone,

 

I have here an indeterminate theropod tooth from from the Tiouraren Fm of Niger. The locality given to me was Tiouraren Hill, Téneré Desert. I've used Troodon's thread to narrow down the possibilities:

 

1.23" long

0.49" wide

Distal serration density is 2.33/mm (mid-carina)

Mesial serration density is 2.33/mm (near the tip; no serrations visible mid-carina)

 

It's a partial tooth so I cannot get accurate base/height ratios.

 

I'd appreciate any help identifying this.

 

Thank you,

Bellamy

How far does the mesial carina extend down the outer edge.  Difficult to see with your photos?

Thank you! I was hoping for my first Megalosaurid!

It's generally hard to see. I'm attaching more photographs. Let me know if these are clearer. Otherwise I'll get some under magnification of the mesial carina when I get home. To my eye it looks to be around 2/3

Suggest you do that.  Need to know how far down the carina comes and if its short is it natural worn.

Hi Frank,

 

I'm attaching photos under magnification here. They're all of the mesial side as requested. Hopefully some of these are helpful.

 

Thank you,

Thanks, Images are better and does look like a meglosaurid.  So most likely an Afro. not much else that size in that fauna.

Thank you for confirming that. I'm happy my hunch was correct when I bought this unidentified tooth!
