-Andy- Posted September 7, 2018 Share Posted September 7, 2018 Hi all, I just got this tooth from Tolman Bridge area of Alberta. That area falls within Edmonton Group supposedly. I believe it's a hadrosaur maxillary tooth. Any idea what kinda hadrosaur it could be? Thank you for your help. 5 Looking forward to meeting my fellow Singaporean collectors!

Runner64 Posted September 7, 2018 Share Posted September 7, 2018 Hi Andy, nice looking tooth! Teeth with the denticlez like that are hard to find from North America. Don’t believe it can be narrowed down just like most other cases with several hadrosaurs in the area. Haven’t heard of denticle shape and size varying between species.

Tidgy's Dad Posted September 7, 2018 Share Posted September 7, 2018 Lovely tooth! Love the denticles on this one. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
LordTrilobite Posted September 7, 2018 Share Posted September 7, 2018 Very nice indeed. The teeth do vary a bit between Hadrosaurs. These don't seem to be the best illustrations, but it gives an indication. Parasaurolophus, pretty clear denticles. Undefined Lambeosaurinae. The edges seem pretty smooth. Probrachylophosaurus. Hard to tell from this photo. But the edges seem fairly smooth. Undefined Saurolophinae. Smooth edges. 4 Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...

Troodon Posted April 7, 2019 Share Posted April 7, 2019 Oh I've collected the Tolman bridge, nice area, its the Horseshoe Canyon Formation. Your strong center ridge tells me its a dentary tooth if I compare it to those in my Edmontosaurus maxillas. Horner describes Two Medicine Fm hadro teeth with Big denticles as Gryposaurus dentary teeth see photo. Nothing that is currently described from the HCF that would fit this tooth morphology. I would call it "cf Gryposaurus" Nice tooth. 3 Link to comment Share on other sites More sharing options...
