Auspex Posted June 30, 2008 Share Posted June 30, 2008 Where does this one fit in the taxonomy? I've never heard of it.

Megaselachus13 Posted June 30, 2008 Share Posted June 30, 2008 I remember having read some time ago that the family Cardabiodontidae includes Parotodus. Perhaps Cardabiodon is it's ancestor? Link to comment Share on other sites More sharing options...
Bill Posted June 30, 2008 Share Posted June 30, 2008 Lots of results for Cardabiodon on google KOF, Bill. Welcome to the forum, all new members www.ukfossils check it out. Link to comment Share on other sites More sharing options...
isurus90064 Posted June 30, 2008 Author Share Posted June 30, 2008 Siverson (1999) described a new genus (Cardabiodon) and erected a new Family CARDABIODONTIDAE for it based on material from the Cenomanian of Australia. He moved Parotodus into this family. While creating this new family seemed warranted, moving Parotodus into this family seems less well argued, although it's entirely possibly. He considered the defining tooth characteristics for this family to be the presence of four upper & lower anterior tooth positions. Of the top of my head Cardabiodon has been found in Norway, western Australia, eastern Russia, France, and Kansas.

Cardabiodon is also found in Montana as published by Siverson. 1 Link to comment Share on other sites More sharing options...

Boesse Posted June 30, 2008 Share Posted June 30, 2008 Hey Marcel, you can add Montana to that list. I recently received a reprint by Siverson and (can't remember the coauthor, but his first name was Johan, and he was a postdoc at UCMP a year ago or so, studying mosasaurs...) someone, 2006 or so (can't recall the journal either). But they described teeth of Cardabiodon and Johnlongia from eastern Montana (I can't remember the rock unit either!). I can't remember a whole lot, primarily because I left my folder of cretaceous shark papers back in MT for the summer. Bobby Link to comment Share on other sites More sharing options...

Bobby Bobby/Marcel The authors of the paper were M. Siverson and Johan Lindgren. This paper also reported the presence of Cretoxyrhina mantelli. The teeth were from the Fairpoint mb of the Carlile shale (Lower Middle Turonian) in east-central (Mosby area) of MT.

Northern Sharks Posted July 1, 2008 Share Posted July 1, 2008 This is probably my rarest tooth- Trigonotodus alteri, the cusped giant thresher. Of the 3 types of giant thresher (serrated and unserrated with no cusps being the other 2) I believe this is the rarest species. The only place they are found in the world is the Oligocene of South Carolina. I think its a lower center/anterior; they're smaller based on modern thresher dentitions and the main cusp isn't curved. Of the 3 or so that I've ever seen offered for sale, this is the only one without considerable damage There's no limit to what you can accomplish when you're supposed to be doing something else Link to comment Share on other sites More sharing options...

Of the 3 or so that I've ever seen offered for sale, this is the only one without considerable damage Wow, this is a spectacular tooth. Is this analogous to the angustidens in the Carcharocles line? (ie, lost the cusps and evolved into the Miocene/Pliocene giant threshsers?) Here's a tooth that is pretty uncommon. It's a commons species (hastalis/xiphodon/whatever) that's found in Aurora, but the dimensions are freaky. It's 2 3/8".... wide. (2 11/16" max slant length). Must have been a huge shark!

I'm in Delaware right now but when I get back I'll take pics Link to comment Share on other sites More sharing options...

The tooth attached is a Cardabiodon vernator from the Carlisle Shale from Kansas. Wow, what a beautiful tooth! Looks to me as if it is from the Parotodus family?

Auspex Posted July 1, 2008 Share Posted July 1, 2008 Not shark teeth, but uncommon none the less. These are Avisaurus archibaldi, a late Cretaceous bird, all from Hell Creek. The largest is 1/4". They are sort of the "6 inch Meg" of the bird fossil world.

isurus90064 Posted July 1, 2008 Author Share Posted July 1, 2008 Eocene shark vert string still in the jacket. This one comes from the area around Oued Zem, Morocco. There are a total of 68 verts on the surface with a few more slightly buried in the matrix. This piece has no restoration or repair done to it.

Guest N.AL.hunter Posted July 1, 2008 Share Posted July 1, 2008 Something struck me as I looked at those vertbebrae. They appear to be placed in an ancient Egyptian text that only I know how to read. To help you understand what it is saying, I've translated it here: "These vertebrae belong to N.AL.Hunter. If found please return." Link to comment Share on other sites More sharing options...

Sharktoothguy11222 Posted July 2, 2008 Share Posted July 2, 2008 I contest N.AL.hunter's translation. It is clearly Arabic, hence being from Morocco. It most likely says "Give them to the guy with the longest name on the forum". This is clearly me! LOL ANAYWAY That is a truly one of a kind collector piece. I think Gordon Hubbell has an associated set of Otodus verts. You would'nt happen to have an id on that beauty now would you ??? Tha tighin fodham, fodham, fodham!
