Fossildude19 Posted March 1, 2020 Share Posted March 1, 2020 Arthropleura was my first thought, Rob. Great find! 2 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Ash Posted March 1, 2020 Share Posted March 1, 2020 I didn’t realise that occurred there.

digit Posted March 2, 2020 Share Posted March 2, 2020 I love it when I learn new things here--lots of room for that. These guys could grow to enormous sizes due to the higher oxygen content back in the day. The lack of sophisticated respiratory systems limits modern day arthropods. https://en.wikipedia.org/wiki/Arthropleura Cheers. -Ken 3 Link to comment Share on other sites More sharing options...

I realized it wasn’t a jellyfish out in the field even though it was dirty. Not to mention my glasses were dirty. My hands were filthy. And I was standing on a 45 degree incline straddling pricker bushes. A little context. Good times. 2 Finding my way through life; one fossil at a time.

RCFossils Posted March 2, 2020 Share Posted March 2, 2020 Unfortunately, I believe it is plant material. Not sure exactly what but maybe something like stigmaria. 6 Link to comment Share on other sites More sharing options...

Carl Posted March 3, 2020 Share Posted March 3, 2020 My gut also said Arthropleura, but this one is surprisingly hard to distinguish from a plant. 2 Link to comment Share on other sites More sharing options...
PaleoNoel Posted March 3, 2020 Share Posted March 3, 2020 That's awesome! I suggest you submit it for Invertebrate Fossil of the Month. From what i've seen online it does seem to be arthropleura. 1 Link to comment Share on other sites More sharing options...

GeschWhat Posted March 8, 2020 Share Posted March 8, 2020 It sure looks like the outer edge of a tergite from an Arthropleura to me, but I've never actually seen one from Mazon Creek. Notice the ridge where part of the fossil has chipped off. Arthropluera have a ridge on the underside of their tergites in some areas. As an example of this, here is the underside of a tergite from Poland. 1 Lori www.areallycrappystory.com/fossils www.facebook.com/fossilpoo Link to comment Share on other sites More sharing options...

Hopefully I can get RCFossils, or Fiddlehead, to confirm that. You’re making a very strong, and valid, point in your assessment. That’s again for bringing it to light! 1 Finding my way through life; one fossil at a time. Link to comment Share on other sites More sharing options...
RCFossils Posted March 10, 2020 Share Posted March 10, 2020 While I would love this to be a tergite off of an arthropleura, i am still fairly certain this is plant material. I see the ridged area that you are referring to, it just does not look like any Mazon arthropleura or arthropod material that i have seen. Link to comment Share on other sites More sharing options...

GeschWhat Posted March 10, 2020 Share Posted March 10, 2020 I know very little about Mazon Creek fossils. Half the time, the jelly fish and tully monster pieces don't even look like fossils to my untrained eye. I have been studying Mazon Creek herbivore coprolites over the last 1 1/2 years. As a part of this, I have been studying modern millipedes. I only have 3 species of flat millipedes, two of which have a surface texture to their tergites that would be somewhat similar to Arthropleura. However, they are very, very small. Here is a tergite from a Polydesmus sp. You may be right. This might be plant material. However, I'm getting a really strong millipede vibe. I haven't been able to find any really good photos of Mazon Creek Arthropleura tergites, but this does seem to fit with some of the Polish specimens. 2 Lori www.areallycrappystory.com/fossils www.facebook.com/fossilpoo Link to comment Share on other sites More sharing options...
Rob Russell Posted March 11, 2020 Author Share Posted March 11, 2020 Wow, GeschWhat. You may truly be on to something. The individual top view in your visual is mighty compelling. The shape is distinctively very similar. Yet I cautiously consider “shape” as a identifying tool. I certainly appreciate you taking the time to provide us with your expertise on these neat creatures. Considering I have nine! Thank you again; GW! So the mystery continues! Finding my way through life; one fossil at a time. Link to comment Share on other sites More sharing options...

If you tell me you have an African Giant, I am going to be extremely jealous! I fell in love with the little critters after I got my first one. I have Texas golds, Florida Ivories, Smoky Ghost, spotted snakes and the flats that I mentioned the largest being Auturus evides.

Rob Russell Posted March 11, 2020 Author Share Posted March 11, 2020 Hahaha! Wupsies. That should read, “I have none”. Not “nine”. I’m a residential carpenter contractor, and have zero knowledge on Arthropleura’s. I would edit it, but that would make this post mute. Finding my way through life; one fossil at a time.

Well, if you ever do want an adorable, easy pet, I highly recommend millipedes - especially Florida Ivories. They come out to play a lot more than most, and have the cutest little faces. 1 Lori www.areallycrappystory.com/fossils www.facebook.com/fossilpoo Link to comment Share on other sites More sharing options...
