Interesting coprolite

Recommended Posts

belemniten

Hi guys, 

 

I normally collect only bones but in the layers where I collect them, coprolites are also often abundant. But mostly they are not very well preserved so I don't take them with me. This one is the best one I found so far and I wonder if it might be possible to find out which animal "produced" it ;) It comes from the so called "Grenzbonebed", which is a triassic layer between Muschelkalk and Keuper. Its approximately 4 cm long.

It would be great if someone can help here. Maybe @GeschWhat? My personal guess would be that it comes from a fish (maybe shark)...

Thanks and stay healthy!

It reminds me of a plate of an arthropod.

WHAT??? You leave them behind??? :D

 

I'm getting an arthropod vibe as well. That ridge along the edge isn't something you would see on a coprolite. On the top left in the second photo, it looks like something might have been gnawing on it. Interesting though.

Yes normally... nearly in every single stone is at least one :D 

 

Thanks for the interesting and helpful thoughts! I am not sure if arthropods even occur in this layer.  Maybe @Pemphix can help here?

No arthropods in these layers, to much energy (bonebed) during building-period.

This is a broken part of a bone from stereospondylic amphibium.

You can easily see the ornamentation which is typically.

This narrows it down to the skull region or the clavicula/interclavicula.

My guess would be a skull-fragment from the skull-roof somewhere in the back region near neck (squamosal, tabular,..).

Why do you think it is a coprolite ?

Many thanks! 

I thought that it's a coprolite, because of the structure. I have never seen a bone like that...
