Awesome collection and nicely organized. Thanks for sharing. Did you find any of these teeth or did you buy and/or trade?

Wish I could say I did but just from buy and trade. From Illinois so occasionally go in Mazon Creek when I get the chance :D

Now if anyone could help me with this next tooth that’d be great! Was sold as Pachysephalosaurus but always have troubles trying to spot a difference between Pachysephalosaurus and Thescelosaurus.

 

Pachysephalosaurus cf.

I think Troodon's post on differentiating between the two is very helpful, I would lean more towards this tooth being a Thescelosaurus tooth based on the info in that post however I may be wrong with the ID.

No I think you’re right! I took a look at Frank’s post last night and came to the same conclusion. Thescelosaurus maxillary tooth.

 

Im fine with this because I was looking for one anyways :D now I know what to look for in a Pachysephalosaurus tooth.

Agreed Thescelosaurus maxillary. Hopefully you should be able to find a Pachysephalosaurus soon

Love all those hadrosaur spitters.:)

 

Thanks :) not the most pretty, but I thought it would be a cool idea to get one (or attempt) from every formation.

Appalachiosaurus montgomeriensis

(Tyrannosauroid)

Campanian

Tar Heel Formation

Cape Fear, North Carolina

 

Measurement: 30 mm

 

ID was done by David Schwimmer, the one whom described Appalachiosaurus. The serration count for Appalachiosaurus is also 11-14 per 5mm whereas Dryptosaurus is 9-10 per 5mm. This tooth also falls into the Appalachiosaurus range at 13 serrations per 5mm.

Siamosaurus suteethorni

(Spinosaurudae)

Barremian

Sao Khua Formation

Measurement: 20 mm

 

 Comes from a very old collection prior to ban.

Very cool teeth. Very hard to aquire stuff.

Life started in the ocean. And so did my interest in fossils;).

Hadrosaur indet.

Campanian

Tar Heel Formation

Cape Fear, North Carolina

Lophorhothon is the only describes hadrosaur from the formation. However, like with most Cretaceous deposits, the possibility of multiple hadrosaur is prevelant and is most likely the case.

I know Hypsibema is also known from campanian deposits in NC (pretty sure tar heel included), but I agree that it's likely more accurate to keep it as Hadrosaur indet.

Not that I doubt you, but do you happen to have a paper or article on it? :) with so little published on the eastern coast of the United States for dinosaurs, made research for these two teeth difficult.

Edward Cope reported on Hypsibema from North Carolina in 1871 in “Observations on the distribution of certain extinct Vertebrata in North Carolina”.

Great new additions as always Matt

Looking forward to meeting my fellow Singaporean collectors! Do PM me if you are a Singaporean, or an overseas fossil-collector coming here for a holiday!
