I found this at the Lost Creek Dam site at Jacksboro Texas. It is the Finis Shale Member of the Graham Formatoion in the Upper Pennsylvanian Sub-period. I don't often find the apical end of any nautiloids so I was thinking it could help with the ID. There is a dark spot on the oral end that may or may not be the siphuncle, it is not clear. I thought it may be a Bactrites but it would be one without the hemispherical apex and constriction you see on some. It also has a cameral ratio higher than some Bartrites at around 3. I don't know what the black dots are.
gwestbrook posted a topic in Fossil Hunting TripsI had forgotten I had found Worthenia fossils of this size at the Jacksboro Pennsylvanian period Finis Shale site. Found these probably on my first or second collecting trip to that site 5 or 6 years ago. I have boxes of stuff I haven't looked in for years. Finding stuff that's surprising me.
