Hi again, Frank!  You know what, when I tilt the tooth in the sunshine while looking at it using my loupe, there may be evidence of faint/worn-down serrations close to the tip, but I can't be entirely sure...  Perhaps more photos are called for?

Those serrations are important for identification makes the task a hit mire difficult.  Dromaeosaurid's have a different serration density between the two edges.  Fewer serrations are found on the inside edge so they are a bit wider.   The outer edge, mesial, are slightly narrower so more of them.    Homework assignment.. can you see if you can see any difference between the two even though they are faint.  If they look the same that will point us in another direction.  If not doable thats okay...

Not getting a great view but think they are similar.  Its a tough call without a clear picture of those serrations and might change if I have it under a scope but would lean toward Tyrannosaurid :).   If you ever get a chance to put under a scope check it out.

Regardless of the identity of the tooth, I'm over the moon with having found it!!!  I don't have a scope to use, and in the past I've tried to take photos of specimens using my camera and my loupe, but it hasn't worked.  I'll try again, though - if I'm successful, I'll let you know.

 

Thanks so much for taking the time to help me uncover the likely identity of this little tooth - I really appreciate it!!! :SlapHands:

What a beautiful tooth! Monica, congratulations for your great find and for your national day.:yay-smiley-1:
And Mr. Troodon is a gentelman! Always available to share his knowledge :tiphat:

Thanks @Earth Chemistry, @ricardo, and @Ludwigia!  

 

We just finished hosting our parents for Canada Day dinner: BBQ hot dogs, baked potatoes with all the trimmings, and salad for dinner followed by homemade lemon sponge cake, vanilla ice cream, and local strawberries for dessert - a delicious end to a wonderful day that began with finding a tyrannosaurid tooth!  I realize how very lucky I am :)

 

Thanks to all of my forum friends for their help and support over the years - it is truly appreciated.

This afternoon I spent some time picking through the Aguja matrix again, and I found a couple of items that I was hoping I could get some help with (Frank @Troodon I hope I'm not bothering you too much!!!):

 

Melvius fish tooth:

unknown item - At first I was thinking a tooth, but now I'm not so sure - perhaps a bone fragment?  One of the photos looks like there could be tiny tooth sockets in the piece, but perhaps it's just wishful thinking on my part:

No bother happy to help...like to see your finds

 

Big melvis.  

Not a tooth but could be a jaw.  Nothing comes to mind will look at some papers.   Hopefully other eyes will chime in.

I see a Melvius type tooth but can't say much about that last piece.  

Thanks

Thanks @jpc for having a look, and thanks @Troodon for constantly trying to help me! :)

 

Looking at the unknown piece more closely, I'm pretty sure it's a jaw fragment that appears to have differently-sized tooth sockets but unfortunately no teeth.  I'll see if I can get better photos of it when the lighting is better here, but if it can't be identified I'll just label it as an unknown jaw fragment.

 

Thanks once again!

I''m back with a few more items to show...

 

A couple of pictures of the unknown item from yesterday, which I'm thinking is a jaw of some sort - perhaps fish?  What do you think?

Vertebra - any idea as to who it belonged to?

Rib bone perhaps?  Any idea as to who it belonged to?

A very weird bone - does anyone recognize it?

That's all for now - thanks in advance for your help!

There are a couple of publications describing micro materials but those focus mostly on teeth.  So identification of bones, verts is not  going to be easy or not doable.  

The first item, good photos,  does look like a jaw and my guess its fish.  I found quite a few vertebrae like the one you found but have been unable to find an owner.  My guess its fish.   No idea on you last two items.   That long thin bone looks a bit like a center metatarsal but thats a guess.

Hi Frank @Troodon et al.!

 

Here are a few more teeth to show...

 

Three views of Tooth A - due to the circular base, I'm thinking fish or small croc?

Three views of Tooth B (at least I think it's a tooth!):

Two views of Tooth E - perhaps a broken gar tooth?
