GeschWhat Posted May 8, 2020 Share Posted May 8, 2020 I purchased this beautiful pile of poo pellets, and the matrix contained this little hitchhiker. Since I know next to nothing about trilobites, I was hoping for an assist. He dates from the Middle Ordivician (Llandeilian), and was found in the Traveusot Group (Angers), in La Meignanne, Maine-et-Loire, France. I don't know if the second photo is more of Jaques or just another trilo-bit. Thanks for indulging me. Yeah, I'm digressing..... 7 Lori www.areallycrappystory.com/fossils www.facebook.com/fossilpoo Link to comment Share on other sites More sharing options...
Coco Posted May 8, 2020 Share Posted May 8, 2020 @GeschWhat, I have found some fossils from this area with what you call "pile-o-poo". I always wondered if they were coproliths or eggs. The friends of the region more specialized in trilobites than me have never been able to answer me... So these are coproliths !

I have been looking for nice examples of Ordovician coprolites for a long time! I have two other examples from the same location where the coprolith accumulation is more random. Because of the arrangement in this particular instance, I'm thinking (hoping) this pile might be at the entrance to a burrow. I started excavating on the reverse to see if I can verify this. 1 Lori www.areallycrappystory.com/fossils www.facebook.com/fossilpoo Link to comment Share on other sites More sharing options...
Pumpkinhead Posted May 8, 2020 Share Posted May 8, 2020 Ormathops would be my best guess 2 Link to comment Share on other sites More sharing options...

piranha Posted May 8, 2020 Share Posted May 8, 2020 The eyes of Ormathops are too small. Instead this specimen matches better with some of these possible large-eyed genera. A pygidium would help with a confident ID! figures from: Lebrun, P. 2002 Trilobites de France. 1, Généralités sur les Trilobites, Massif Armoricain (Bretagne, Normandie Vendée).

GeschWhat Posted May 8, 2020 Author Share Posted May 8, 2020 Here is a pygidium from a larger trilobite from the same area. I realize there may be more than one type in the area, so I don't know how much this one will help. It is a headless, rolled specimen, so this is the best I can do to capture the features.

From the illustration you provided, my larger specimen must be a different type of trilobite than that in the matrix.

sharkdoctor Posted May 26, 2020 Share Posted May 26, 2020 Thanks! I've been admiring your taste as well, though I would call it "specialized", or maybe "superb" Thanks for the close-up. The lack of surface detail is interesting. Shape doesn't seem completely homogeneous. -a On 5/8/2020 at 2:53 PM, GeschWhat said: You, sir, are obviously a man of refined taste.

fifbrindacier Posted June 24, 2021 Share Posted June 24, 2021 (edited) I just stumbled on that post. That's a nice piece of Tomaculum. I found something like this on a nodule from La Hunaudière, not far from where yours come from.
