mikeymig Posted April 12, 2021 Share Posted April 12, 2021 Phyllocarid Collecting trip 4/9/2021 Devonian N.Y. A beautiful Echinocaris punctata (Hall) with mandibles and antenna. This is as found unprepped and awesome. You can see the complete mandibles under the carapace, attached pyritized brachiopods, and a first for me, pyritized antenna. Happy collecting! 2 8 Many times I've wondered how much there is to know. led zeppelin Link to comment Share on other sites More sharing options...

oilshale Posted April 12, 2021 Share Posted April 12, 2021 Wow, great find - that would be very interesting to see a CT scan of it. Because of the pyrite you should get a good contrast. 1 Be not ashamed of mistakes and thus make them crimes (Confucius, 551 BC - 479 BC). Link to comment Share on other sites More sharing options...
FossilDAWG Posted April 12, 2021 Share Posted April 12, 2021 Way cool! Have structures such as antennae been described from the species before? I wonder if there are other structures such as appendages buried in the matrix. Thomas' suggestion of a CT scan is a good one if you have a way of getting that done. This might be a scientifically important find. Don 1 Link to comment Share on other sites More sharing options...

jpc Posted April 12, 2021 Share Posted April 12, 2021 Cool...As a guy who rarely delves into the Paleozoic and know very little about phyllocarids, can you show me what we are looking at. Link to comment Share on other sites More sharing options...
Jeffrey P Posted April 12, 2021 Share Posted April 12, 2021 First off, I've never seen an Echinocaris robust enough to remove from the matrix. Then there are the intact mandibles and those pyritized brachiopods and bryozoans. I assume that you are assuming those other structures are antennae. Given that I've never seen antennae preserved on a phyllocarid, I am not sure, but suspect you're right. I agree with others, a potentially important specimen. Congratulations Mikey and thanks for sharing it. 1 Link to comment Share on other sites More sharing options...
mikeymig Posted April 12, 2021 Author Share Posted April 12, 2021 I'm not someone that jumps to conclusions or attempts sensenatiolism with my finds. I've examined this specimen under the microscope and I feel that these are the antenna of the Phyllocarid. This is a very low energy environment and fossils in this unit are as they were at the bottom of the Devonian Sea 380 million years ago. I have found more than a few Phyllocarids in my time. My gut told me that what I was looking at the moment I found this specimen is the animals antenna. I will get it prepared and then I can verify my assertion. They are pyritized and have an attachment articulation where the two sides meet. jpc Here is a snapshot of line drawings from Halls vol.7. It shows a specimen like mine with the mandibles and what the animal looks like complete. Unfortunately the telson (tail) was lost to the elements before I found it. 5 Many times I've wondered how much there is to know. led zeppelin Link to comment Share on other sites More sharing options...

Notidanodon Posted April 13, 2021 Share Posted April 13, 2021 Great find! If you ct scanned it beforehand, the prepper could get a better idea of where things are and if something goes wrong, an image could be saved for science 1 Link to comment Share on other sites More sharing options...
