izak_ Posted November 17, 2018 Share Posted November 17, 2018 Was up at Lake St. Clair, NSW looking for late(?) Carboniferous marine fossils and came across this thing. I am thinking that its a fish tooth but not too sure as no vertebrate material has been reported from the site to my knowledge. Please let me know if clearer photos are needed This specimen is aprox. 7 mm long Thanks, Link to comment Share on other sites More sharing options...
Rockwood Posted November 17, 2018 Share Posted November 17, 2018 If I could find something that looks like a hinge line I'd call it an ostracod. Link to comment Share on other sites More sharing options...
Fossildude19 Posted November 17, 2018 Share Posted November 17, 2018 Looks like a paleozoic shark crusher tooth, to me. Maybe @Archie @jdp @JimB88 @TNCollector will have some ideas. Nice tooth. Thanks for posting it.

Innocentx Posted November 17, 2018 Share Posted November 17, 2018 I can't tell from photos but does the surface have pits, raised bumps, or lines? "Journey through a universe ablaze with changes" Phil Ochs Link to comment Share on other sites More sharing options...

Archie Posted November 17, 2018 Share Posted November 17, 2018 Definitely looks like a Holocephalan tooth like Psephodus, if it is those pits are dentine tubules. Cool find! Link to comment Share on other sites More sharing options...

Archie Posted November 17, 2018 Share Posted November 17, 2018 Struggling to see the pits but still pretty certain its a tooth, can you get a larger image? The morphology looks a better match for Lagarodus than Psephodus in this pic. Link to comment Share on other sites More sharing options...

So hard to get decent pics haha Link to comment Share on other sites More sharing options...
Archie Posted November 18, 2018 Share Posted November 18, 2018 Oh yeah I see them! It sure is haha thats a really beautiful tooth with the two colors! If vertebrate remains are very rare or unheard of at locality you should get it looked at, it would be awesome if it was something new! Link to comment Share on other sites More sharing options...

Yeah I will get it looked at, just have no idea who to show it to. Nobody here that I know of works with Carboniferous fish (could be wrong) since theres so little material to go around here.... maybe I'll try Alex Ritchie. And thanks for the info and help Link to comment Share on other sites More sharing options...
Archie Posted November 18, 2018 Share Posted November 18, 2018 Yeah that can be a problem! Good luck I'm sure someone will be very interested to see it. Looking at the bigger pic it looks like the top of the root is just showing along the straighter edge, is the tooth in a limestone that would dissolve in vinegar? The root would look beautiful prepped out Link to comment Share on other sites More sharing options...

Archie Posted November 18, 2018 Share Posted November 18, 2018 Good luck! I'd just try and keep the rest of the tooth out of the vinegar bath as much as possible so as not to discolor the crown and it should hopefully bring out the detail on the root!

Archie Posted November 18, 2018 Share Posted November 18, 2018 Then again it might be fine to soak the whole tooth I'd just keep a close eye on it and bring it out and dry it very regularly to make sure its going back to the same colors when dry.

MrR Posted November 22, 2018 Share Posted November 22, 2018 Interesting tooth, and apparently pretty rare from any area, let alone a new one altogether. All I know about it is what I read in the accompanying article. While I suspect the OP may have read it already, I'll supply the link to make it easier for others. Congrat's on what looks like a very nice find. This newbie's eyes probably wouldn't have seen tooth on that one. Good eye, and g'day. Cheers.

Scylla Posted November 24, 2018 Share Posted November 24, 2018 I was just thinking that showing it to an expert before soaking in vinegar might be a good idea. Just in case it is a new type fossil. Link to comment Share on other sites More sharing options...
