Ruger9a Posted January 21, 2020 Share Posted January 21, 2020 Good morning all. I have a fossil that was identified as "plant cross section(?) from Green river". I'm wondering if it's actually a fruit seed pod similar to Bonanzacarpum spungerorum species. It has similar form and shape. I applied a lite coat of easily removeable wax for protection.

Rockwood Posted January 21, 2020 Share Posted January 21, 2020 From the images I see on line I would stay with stem. The conducting tissues/structures being the distinction. 1 Link to comment Share on other sites More sharing options...
paleoflor Posted January 21, 2020 Share Posted January 21, 2020 Have a look at Manchester and Lott (2019), describing Bonanzacarpum. They figure one with sixfold symmetry on Figure 2L. Perhaps contact the authors? https://content.sciendo.com/configurable/contentpage/journals$002fif$002f75$002f2$002farticle-p281.xml 2 Searching for green in the dark grey.

Ruger9a Posted January 21, 2020 Author Share Posted January 21, 2020 Thanks guys. The only reason I posted this today was because of the post by doushantuo (additions to paleocarpological knowledge:The Eocene) this morning. They looked so similar and my fossil does not exit the back of the plate which lead me to hope this was an reasonable identification. Shooting for the moon I guess. 1 Link to comment Share on other sites More sharing options...

It's not the first time and probably won't be the last. We can all hope for an identification for a suspect fossil, right? Thanks for taking the time to respond. 1 hour ago, Rockwood said: From the images I see on line I would stay with stem. The conducting tissues/structures being the distinction. Thanks again Rockwood. I suspected this fossil as being labeled incorrectly because of the shape of the stem and the lack of protrusion on the reverse side. I will leave it as labeled.

Pity, because I think you might be correct with Bonanzacarpum, which can display sixfold symmetry similar to your specimen. Your observation that the "stem" does not extend to the backside of the plate also supports your ID... Searching for green in the dark grey.

I will complete some additional research to confirm. I was so sure about this ID after seeing doushantuo's post this morning. Link to comment Share on other sites More sharing options...

My quick image search pales in comparison to the reference these guys use. Link to comment Share on other sites More sharing options...

Ruger9a Posted January 21, 2020 Author Share Posted January 21, 2020 Exactly, I download the PDF report and on 283 and under the fourth paragraph (top tight) "Diagnosis", it states they can be "with 4 to 6 equal to unequal sides". Link to comment Share on other sites More sharing options...
