Fossildude19 Posted December 11, 2019 Share Posted December 11, 2019 Your first photos are too small and blurry to make out any detail.

dinosaur man Posted December 11, 2019 Author Share Posted December 11, 2019 I’ll try to get better ones but it’s so small it’s hard to get a good photo. Link to comment Share on other sites More sharing options...

DinoHunter1105 Posted December 12, 2019 Share Posted December 12, 2019 It almost looks like a shark vertebrae, but still a little hard to see, maybe a measurement will help a little bit. 1 Link to comment Share on other sites More sharing options...
connorp Posted December 12, 2019 Share Posted December 12, 2019 Where is the first specimen from? The second looks geological, and yes the third appears to be a coral. Link to comment Share on other sites More sharing options...
dinosaur man Posted December 12, 2019 Author Share Posted December 12, 2019 @DinoHunter1105 it's 0.9 cm by 1 cm Link to comment Share on other sites More sharing options...
dinosaur man Posted December 12, 2019 Author Share Posted December 12, 2019 And @connorp the first specimen is from the Bois Blanc Formation. Link to comment Share on other sites More sharing options...

dinosaur man Posted December 12, 2019 Author Share Posted December 12, 2019 @Kane have you seen anything like my vertebra above in the Bois Blanc Formation? Link to comment Share on other sites More sharing options...
Kane Posted December 12, 2019 Share Posted December 12, 2019 You would not likely find vertebrae in the Bois Blanc. The only vertebrates would be placoderms, but those will generally only preserve their plates. Until a clearer picture is taken, I would hazard to guess that it is coral. I have not heard of placoderm material found in this formation, but certainly abundant coral and brachiopods (the heavy brach layer is a good stratigraphic index if it underlies the coral-crinoid layer, which distinguishes the Edgecliff Member). 2 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
dinosaur man Posted December 12, 2019 Author Share Posted December 12, 2019 Thanks Kane, I’ll get some better photos tonight, my phone camera doesn’t work the best with small objects, so It will be tricky. Link to comment Share on other sites More sharing options...
DinoHunter1105 Posted December 12, 2019 Share Posted December 12, 2019 I would have to say that the vertebrae is in the fish/shark family, cant put it on a specific species though. 1 Link to comment Share on other sites More sharing options...

I can see this as a coral, just a little blurry, is it smooth on the circular parts of it? Link to comment Share on other sites More sharing options...
FossilDAWG Posted December 12, 2019 Share Posted December 12, 2019 The fish that occurred at the time and environment in which the Bois Blanc formation was deposited were primitive sharks and placoderms. These fish had cartilaginous skeletons, and ossified vertebrae have not been described from Devonian marine deposits. It is misleading (not intentionally so, BTW) to compare Cretaceous and Cenozoic sharks to Devonian sharks, or Carboniferous sharks as well, for that matter.

Placoderm vertebrae have an unusual shape, and are composed of thin, perichondral bones. One determinant would be arch bases in the synarcual. 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

Pemphix Posted December 12, 2019 Share Posted December 12, 2019 No Vertebra. No Vertebrates described from this Formation. I Posted a brief summary in another request of dinosaur man. Link to comment Share on other sites More sharing options...
DinoHunter1105 Posted December 12, 2019 Share Posted December 12, 2019 Sorry, I was not familiar from where it was from, that time period does not have as much studying from me. Link to comment Share on other sites More sharing options...
FossilDAWG Posted December 12, 2019 Share Posted December 12, 2019 No problem. We all make suggestions based on what is familiar to us. That is one of the things I really like about the Forum, we all bring our own experience to the table and we all have the opportunity to learn new things every day.
