I have collected nearly 100 devonian bones which I believe to be come from Dunkleosteus and other smaller species. Some have distict shapes. I am trying to place and locate the position of these bones but I have no reference. I have several which do not fit the species I've found in research but were collected from the same matrix. I am looking for someone who might help me with this project. I live in Ohio, USA.
Thanks, Rich
