Updated display:

I plan to number each tooth in the rikers with a label and correspond these to a sheet on the back of the riker box and an excel spreadsheet. If anyone has suggestions on how to get the labels to stick without moving (too thin to stay in place) they are much welcome!

 

In the meantime, some other neat dino fossils I have but never posted:

Juvenile raptor claw

Hell Creek Formation

Montana

 

Sonorasaurus thompsoni gastroliths

Turney Ranch Formation

Wetstone Mountains, Arizona

 

These pieces have an interesting story and were gifted to me by the paleontologist whom described Sonorosaurus 20-30 years ago. 

 

Amazing collection, really like the Sonorosaurus gastroliths, I love fossils with an interesting back story/history!

Theropod indet.

Cretaceous (Berriasaian)

Chamblanc Quarry

Cherves Richemont, Cherves-de-Cognac, France

One more additional piece of information regarding theropod teeth from Chablanc Quarry in France.  Specimen CHEm03.537, a holotype tooth for Nuthetus sp. found in Chamblanc Quarry was described back in 2010 but I have only recently found information on what these so-called "Nuthetus destructor" teeth from France should look like:

Pay no attention to A, B, or D in the photo above, they are irrelevant.  The line on the far right is 1 mm sized to each specimen.  Specimen C is holotype CHEm03.537 and is what a Nuthetus sp. tooth from this location is described as.  Labiolingually compressed and also having a divot in the middle of the tooth which corresponds to some teeth found in England.

 

These are the holotype (only known from teeth) specimens of Nuthetus destructor found in England.  Keep in mind, Nuthetus is NOT described from the Wealden Group at the moment but the Lulworth Formation, Purbeck Group.

 

Much debate over what these teeth belong to and is very hard to describe isolated tooth holotypes.  Nuthetus sp. is currently described as a dromaeosaurid but may be considered a proceratosaurid tyrannosauroidea.  For now, leave as Theropod indet. but be aware of what you have.

@Runner64 do you have this PDF article ? I am interested in

Very nice tooth.  I dont see the typical Dromaeosaurid characteristics on that tooth, one that is a bit recurved with unequal serration density unequal so theropod indet. is indeed the best call.

Frank, I thought you might find this interesting for identifying theropod teeth in Neovenator, Eotyrannus, and Nuthetus.  I found a paper back in 2004 by Sweetman, S. talking about velociraptorine teeth on the IoW where he used multiple speciments to take these measurements and classify them.  However, he finishes the paper stating larger sample size is needed to confirm measurements.  However, the MDC and DDC are quite fine for Nuthetus making it atypical for a dromaeosaurid in my opinion.  If you'd like, I could send a link to you to review.

I love your new updated display, very striking.

I also am fascinated by gastroliths.

Finally found a little Nanotyrannus tooth I liked:

 

Nanotyrannus lacanensis

(Tyrannosauroidea)

Cretaceous (Maastrichtian)

Harding County, South Dakota

Hell Creek Formation

~1”

I assure you, sir, shark teeth are always relevant.

Of course they are . Perhaps I should have stated differently

It's alright.  I know you're excited about dinosaurs.  You have a lot of interesting specimens.

Dinosaurs are my passion but I find all of past life interesting. I have had the opportunity to collect shark teeth before in South Carolina. Seemed to be everywhere! And I have to admit, it was quite exciting  

[Runner64]

A long time since I got a new dinosaur tooth. However, here is a new one. 
 

Nigersaurus taqueti

(Rebbachisauridae)

Aptian-Albian

Elrhaz Formation

Tenere Desert, Niger

 

Something I had not realized about Nigersaurus is that all the teeth were located very far front in the dentary and maxillary jaws. For this reason, Nigersaurus had very slender teeth. Each tooth in the jaw had 9 replacement teeth under it making for a whopping 500 teeth in the jaw at one time (holy cow!). Another thing to note is that the enamel on Nigersaurus teeth is much thicker facing outward (distal?) than inward of the mouth. 
If you were to look at a skull of Nigersaurus, you may notice that the jaws are actually wider than the entire skull of the enamel.

 

Just a very bizarre creature!

Sauropods

 

Rebbachisaurus garasbe

(Rebbachisauridae)

Cretaceous (Cenomian)

Kem Kem Beds

Taouz, Kem Kem Basin, Morocco

Size: 0.7”

@Troodon what are your thoughts on this tooth?  Upon looking at it further, I don't believe it is Rebbachisaurus garasbe but rather a Titanosaur indet.  Maybe Rebbachisaurus morphotype II but I am not too sure...Kem Kem is just confusing.

[Troodon]

Lean more towards Titanosaurid.  Yes confusing

[Runner64]

Atlasaurus imelakei

(Sauropoda)

Jurassic (Bathonian)

Guettioua Formation

Boulmane Region, Morocco

Not sure if visible in the photos, but this crown has serrations going along edges of the tooth which is seen in the Atlasaurus holotype.

 

Titanosauridae indet.

Cretaceous (Cenomanian)

Kem Kem Beds

Morocco

 

Theropod indet. (Afrovenator abakensis?)

Jurassic

Tiouraren Formation

Agadez Region, Niger

Anyone feel like taking a stab at identifying shark teeth from Morocco? My friend sent me these teeth without any information:

Those look like some Khouribga shark teeth. The Moroccan teeth are very nice, good buys

These teeth look like Late Eocene from Dakhla, Western Sahara.

Thanks for the paper! Whenever o have a moment, I’ll make sure to sit down and give it a read  

[Notidanodon]

@Runner64 i would definitely agree with dakhla in terms of identification from a quick glance top left is macrorhizodus praecursor and the others require more time to identify

Very cool thanks much!  The top left one was the only one I was completely stumped on so I am glad you took notice of that one.

[Runner64]

Got a new tooth and I FINALLY have a rex tooth from the Hell Creek Formation:

 

Edit: Just realized I misspelt cross-section

[Runner64]

Appalachiosaurus montgomeriensis

(Tyrannosauroidea)

Cretaceous (Campanian)

Tar Heel Formation

Bladen County, North Carolina

 

I’ll have to double check the serration density and compare it to David Schwimmer’s analysis of Appalachiosaurus vs. Dryptosaurus teeth. However, serrations appear too fine to be Dryptosaurus.
