Cephalopod or arthropod, I’m unsure but it looks very interesting
-
Hi @alex-stone ! Did you collect this from the Waynesville/Arnheim formations?
-
-
@matthew-gramling Yes! Waynesville/Arnheim
-
@alex-stone @a-trilobite My best hypothesis is that this is possibly an endoceratid cephalopod like Cameroceras. From the research, I’ve done the Waynesville is known for its cephalopod genera albeit Treptoceras is the key fauna.
-
I’ll send the supporting evidence for my theory soon.
-
-
This one is more critical to my hypothesis: https://pubs.er.usgs.gov/publication/pp1066P

pg P26 figure 5 E2
-
Treptoceras duseri is also an option.

What is it? from the myFOSSIL app 1 month ago1 month ago1 month agoAre these Internal and external casts or different species altogether? I have quite a few of them and quite a few questions! Thanks! #fossil
-
Cyclonema on the right for sure. What’s the left?
-
the left one is 100% an internal cast. the question is whether or not it’s also of the same species or if it’s a different species.

Thank you!

Cephalopods didn’t have skin around their shells, maybe barnacles and bacteria but that’s it. It depends on this-are the shell lines on top or is the covering on top?
-
Appears to be Bryozoan
-
That is the remnant of the orthocone’s shell itself. We normally see only the camerae preserved, which are the filled-in sections, like steinkerns. The shell itself is rarely seen preserved. The outer layer of the shell is called the porcelaneous layer or ostracum and is composed of aragonite prisms.
-
Wow thank you all! Very informative
-
A-trilobite, thank you. What do you mean by shell lines? I have yet to learn about that.
-
I have always been told that those are bryozoan marks showing after death preservation (cephalopod died and sat on the bottle of the sea floor for a while before fossilized)…
-
Shell lines are just the pattern of lines on the shell. They’re very noticeable on this fossil
