Aidan Campos Posted September 26, 2022 Share Posted September 26, 2022 I would really appreciate suggestions on the ID of this microfossil (vertebra?) from a portion of what appears to be a coprolite originating from the Woodbine Group (Cenomanian) of Denton County, Texas, USA. 1 Link to post Share on other sites
Aidan Campos Posted September 26, 2022 Author Share Posted September 26, 2022 Based off the size I’m guessing possibly fish but I have no hands on experience with vert ID. Link to post Share on other sites

JohnJ Posted September 27, 2022 Share Posted September 27, 2022 Nice photos. Can you get anymore details if it is damp? Link to post Share on other sites
Aidan Campos Posted September 27, 2022 Author Share Posted September 27, 2022 Because the specimen is so tiny it dries almost immediately from being dampened however I was able to pull a few images with slightly better detail, nothing substantially different to my eye though. The last three in this set also show the other side of the specimen. 1 Link to post Share on other sites
Aidan Campos Posted September 27, 2022 Author Share Posted September 27, 2022 Also here is the anterior view of the possible vertebra focused on in most of the photos, which seems to have two distinct tubercles/knobs on the body: 1 Link to post Share on other sites

Ptychodus04 Posted September 27, 2022 Share Posted September 27, 2022 It think @Al Dente has it right. The morphology is wrong for any vert that I’m familiar with. Also, some of the other bits in the pic look like the pieces in the image he shared. 1 Link to post Share on other sites
Aidan Campos Posted September 27, 2022 Author Share Posted September 27, 2022 That does look correct, and something I never would’ve guessed! Thank you all for the help. Link to post Share on other sites
JohnJ Posted September 27, 2022 Share Posted September 27, 2022 Great work, Eric! @Al Dente I kept trying to make a roveacrinoid fit, but to no avail. @Aidan Campos the entire piece appears to be the disarticulated fragments of a brittle star. Link to post Share on other sites
