Had to search this one up! What an incredible find, that's a keeper for the ages Link to comment Share on other sites More sharing options...

Kurufossils Posted March 26, 2020 Share Posted March 26, 2020 Loving the theme of this thread! Going to add in this piece of bone from the suborbital of a dunkleosteus species from Ohio. @jpc that bothriolepis from Pennsylvania is an amazing specimen, love seeing east coast material! Definitely would love to find one to add to the collection one day from there as well. 1 Link to comment Share on other sites More sharing options...

Kurufossils Posted March 26, 2020 Share Posted March 26, 2020 @Sinopaleus Thank you very much! I love seeing this material so thanks for sharing your impressive collection! While that is my most complete piece I have a few thick chunks of bone armor from Dunkleosteus as well. 1 Link to comment Share on other sites More sharing options...
Kurufossils Posted March 26, 2020 Share Posted March 26, 2020 This particular piece strikes me, idk what part it wouldve come from but reminds me of a part of the jaw of Dunkleosteus which would be really cool if so, but I have no way of knowing. 1 Link to comment Share on other sites More sharing options...

Pliosaur Posted February 10, 2023 Share Posted February 10, 2023 Dunkleosteus terrelli partial skull From James Boyle PhD: Clinical assistant professor in the geology department of SUNY at Buffalo. Study macroevolution of graptolites and placoderms "Yes, it's most like a Dunkleosteus based on what I can see. You have both anterior dorsal lateral plates of the thoracic armor there. These are the bones that connected with a mobile joint the head and shoulder regions of the armor. The bone to the bottom left is the internal view of the left anterior dorsal lateral plate. The bone under it is the right anterior dorsal lateral plate in external view. The piece that's skewed to the right a bit in the image is part of the left anterior dorsal lateral plate as well. The easiest way to identify which of the two plates is the external (from the outside) view is that there's a sensory line canal on the one plate (it's straight nearly straight line tracing across the one bone at the top). These are the lateral line system you can still see in some modern fishes and act as pressure sensors to detect movement in the water around the organism. They are only found on the outside of the body." "That oblong bone at the top is probably a piece of the paranuchal plate, but if that's the case it's only a very small fraction of it."
