Yay! Nice femur!

Thanks definitely different @hxmendoza

Here is a mystery Dromaeosaurid Tooth -

 

Carinae on midline 

Functional Tooth

Density: Distal 6/mm , Mesial 10-12/mm

 

@hxmendoza  Have you seen Microraptorine teeth?

[Mike from North Queensland]

Some lovely specimens makes me drool  and a lot larger than the material I have been able to collect in Australia.

Just checking that all the measurements are correct - 136 cm is about 4 foot six and larger than what I would expect for a bird.

No, I haven’t. I think this tooth could fall in baby  version of either Saurornitholestine, dromaeosaurine, or Ricardoestesia gilmorei (certainly has a very similar shape). And it’s size can’t rule out a microraptorine. But no real info on any of these out of the HC. 

 

I would stick with your present label for now.

Bird and Pterosaur material is extremely rare in the Hell Creek and Lance Formations.  Over the years I've purchased and found a few bones that I believe fit this category but not certain.  Some may be mammal or reptilian.  I'm not a bird guy so if you see something that does not seem right please let me know.   Not a lot is published so I'm always open to learning.

 

 

 

 

 

 

 

 

 

 

 

I showed this to a well respected theropod paleontologist and the potential ID's were his thoughts

 

 

 

Aviasaurus sp.

Wow! You must have a very fancy camera lense to take clear photos of fossils that small.

I use various tools including USB Scope, Compound Scope, and a Digital Camera with Macro Lens.
