netxitpro Posted September 12, 2014 Share Posted September 12, 2014 Have some teeth I found in the North Sulphur River in Texas. I assume they are Mosasaur, The large one is split in half, and a good view of the inside. Looks different from other Mosasaur teeth I found. Also showing some tips of Mosasaur teeth. Also a pic of a nice shark tooth. Would like to know if anyone has an ideal of the type shark, and if the large split tooth is from a Mosasaur.

SoreBack Posted September 12, 2014 Share Posted September 12, 2014 The shark tooth appears to be Scapanorynchus texanus, Goblin shark. Someone like Non-Remanie will definitely be able to help with the other fossils. Link to comment Share on other sites More sharing options...
netxitpro Posted September 12, 2014 Author Share Posted September 12, 2014 Seems sand sharks and goblin sharks have simular teeth. Thanks for the input. Still would Like to id the large tooth, Masasaur? Link to comment Share on other sites More sharing options...
Auspex Posted September 13, 2014 Share Posted September 13, 2014 ...Like to id the large tooth, Masasaur? I think it is.

fossilized6s Posted September 13, 2014 Share Posted September 13, 2014 I believe it's a Sand Shark. Goblin shark teeth have side cusps. But im no expert.

Troodon Posted September 13, 2014 Share Posted September 13, 2014 The shark tooth is water worn making the ID difficult. I would expect to see some striations on the crown even on a water worn Scapanorhynchus "Goblin" tooth since they are very pronounced but cannot see any. Tiny side cusps may be present on anterior teeth. I would lean toward this being a Carcharias sp. "Sand Tiger Sark". Anterior teeth do contain tiny cusplets but again they are worn away, a wider crown at the base and much lighter striations than Goblins which would not be visible on worn teeth. Other opinions are welcomed. The other teeth as Auspex indicated are Mosasaur. Link to comment Share on other sites More sharing options...
SoreBack Posted September 13, 2014 Share Posted September 13, 2014 Not all Scapanorynchus teeth have cusps, especially the anterior teeth. Whether it's from being worn or not being present from the outset, I don't know. The laterals seem to always have cusps unless it's a beat up tooth. The level of striations also vary from tooth to tooth, we have a fair number of Goblins from here in NJ and they show a large amount of variation as to both presence of cusps to lingual striations. The tooth that Netxitpro found also seems a bit large for a cretaceous sand tiger, I have never personally seen one as large as the tooth in the picture.

You are correct Anterior Scapanorynchus may or may not have cusps and laterals always do. As far as size, Carcharias can get to 20mm while the Goblins can be double that. So I was guessing this one was closer to the 20 than the 40 but if that's not correct its a Scapanorynchus. Link to comment Share on other sites More sharing options...
