Frank Menser Posted October 4, 2009 Share Posted October 4, 2009 (edited) These are teeth I found in E NC. I know the one to the right (above) is a sawfish 'tooth' the others I am not certain of. They measure a little over an inch for the largest. These two measure about 3/4" and are blade like in crossection. Any guesses?

Xiphactinus Posted October 4, 2009 Share Posted October 4, 2009 Frank, are these Cretaceous? If so, those blade-like ones might be Protosphyreana. Not sure about the others. Link to comment Share on other sites More sharing options...
non-remanié Posted October 4, 2009 Share Posted October 4, 2009 (edited) top pic: left - enchodus tooth with a little bit of jaw attached, middle is the same ischyriza as the beauty on the right but its damaged bottom: pretty sure the one on the right is another enchodus tooth. not so sure about the left it could be a few things, xiphactinus, enchodus or even protosphyraena perhaps. im sure youre tired of hearing enchodus for all your cretacous IDs but trust the NJ folks, we see TOO MANY of these! theres a few different shapes of teeth and jaw sections in this nasty fish Edited October 4, 2009 by toothpuller ---Wie Wasser schleift den Stein, wir steigen und fallen--- Link to comment Share on other sites More sharing options...
Frank Menser Posted October 4, 2009 Author Share Posted October 4, 2009 These from Cretaeous strata, though with a possible "bleed" from more recent material due to heavy equipment disruption. Lots and Lots of Enchodus here (lol) just wish I was better at IDing skull frags that would help with reconstruction! Be true to the reality you create.

non-remanié Posted October 5, 2009 Share Posted October 5, 2009 yeah a big problem is that everything is most likely from different fish. pieces are reworked, worn down, broken, etc. so any reconstruction will be tough. if it were from a kansas chalk deposit you might have a better chance at getting anything associated These from Cretaeous strata, though with a possible "bleed" from more recent material due to heavy equipment disruption.

Carl Posted October 5, 2009 Share Posted October 5, 2009 The 2 on the right in the first photo are Ischyrhiza mira, which a sclerorhynchid sawfish. Sclerorhynchids are long-extinct and are not closely related to modern sawfishes. These specimens are more correctly referred to as rotral denticles rather than teeth.

non-remanié Posted October 5, 2009 Share Posted October 5, 2009 "Rostral tooth" has been the phrasing used in several recent scholarly publications, so it also seems to be acceptable usage. ---Wie Wasser schleift den Stein, wir steigen und fallen--- Link to comment Share on other sites More sharing options...
