Bone guy Posted April 25, 2018 Share Posted April 25, 2018 1st pic looks like ptychodus, and if that's the case then that's a sweet find! Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted April 25, 2018 Share Posted April 25, 2018 I think it's a pycnodont mouth plate. Great finds! Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
Miocene_Mason Posted April 25, 2018 Share Posted April 25, 2018 It looks more pycnodont to me as well, either way an amazing set of finds!

sixgill pete Posted April 25, 2018 Share Posted April 25, 2018 Great finds. Any chance we could get better straight on pictures of the first one, the set of teeth @kbodyboard Bulldozers and dirt Bulldozers and dirt behind the trailer, my desert Them red clay piles are heaven on earth I get my rocks off, bulldozers and dirt Patterson Hood; Drive-By Truckers May 2016 May 2012 Aug 2013, May 2016, Apr 2020 Oct 2022 Link to comment Share on other sites More sharing options...

Carl Posted April 26, 2018 Share Posted April 26, 2018 I also tentatively vote for pycnodont and totally agree that this is a fantastic specimen! Link to comment Share on other sites More sharing options...

bone2stone Posted April 28, 2018 Share Posted April 28, 2018 I think there's more to this still there. It would be to your benefit to try and avoid damaging it further. With as much of the ptcodont that you recovered there may be all of it there. Jess b Link to comment Share on other sites More sharing options...

You don't want to ruin it, so don't tamper with it if you don't know what you're doing. Please show us better pictures with scale, as already requested. Greetings from the Lake of Constance.

abyssunder Posted April 28, 2018 Share Posted April 28, 2018 Pychodus pollei - I've never heard of this species. Ok, I've found the species (from the link I've posted in the topic below). Ok, It was misspelled on the label.

Auspex Posted April 28, 2018 Share Posted April 28, 2018 I've not been able to find anything about a picnodont with this complex a topography: They all seem to have fairly simple buttons. I also have the impression that these are pretty large, and they do not appear to be attached to a mouthplate.

Auspex, are you saying that you cannot tell if the teeth are attached to bone of the fish? Do you think that the group of teeth might have been placed into a fabricated mouth plate? I guess a better close-up photo might enable us to see bone texture surrounding the teeth. My goal is to leave no stone or fossil unturned.

abyssunder Posted April 28, 2018 Share Posted April 28, 2018 The picture has not enough details for a more precise ID. Once again, can we have better, close-up pictures of them? BTW, where exactly were they found? Also, this publication might be helpful.

Do you think that the group of teeth might have been placed into a fabricated mouth plate? I guess a better close-up photo might enable us to see bone texture surrounding the teeth. It looks like matrix where teeth are displaced. For a picnodont plate, there should be a bone plate there. I propose that they are in-situ, and that they were originally attached to a cartilage jaw that did not preserve, but held the teeth in original position long enough to fix them in the overburden matrix before decomposing (with the space filled in as it did). In short, I am still suggesting that it may be a ptychodus fossil.

Miocene_Mason Posted April 29, 2018 Share Posted April 29, 2018 Oh, brain just made an idea (first time it’s done that in a while!), perhaps Lepidotes? “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
Max-fossils Posted April 29, 2018 Share Posted April 29, 2018 I have the feeling (I may be wrong) that people are confusing Pycnodus with Ptychodus They're not at all the same! As a reminder to everyone: Pycnodus: ray-finned fish with button-like teeth Ptychodus: big shark with shell-crushing dentition (knobs with wavy lines) Now the amazing mouth plate that I see here is very likely from a pycnodont (of the Pycnodus family) fish, as others have already said. Superb find! The teeth here are: Red: Odontaspidae indet. (I am not gonna try to go deeper than that due to my inexperience with shark teeth) Blue: requiem sharks, Carcharhinus sp Green: stingray barb Orange: Ptychodus tooth Fantastic finds by the way!

(Just kidding of course ) Yeah, a completely alien sensation! Here is a lepidotes dentition (though from the Jurassic). The teeth are simple but in a ptychodus-like jaw. Lepidotes are known from Morocco.
