Possible Minuscule Vertebra from the Woodbine of Denton County, Texas

Recommended Posts

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.

Nice photos.  Can you get anymore details if it is damp?

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.

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:

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.

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.
