Prepped Devonian Phyllocarid found in April 2021 New York
mikeymig posted a topic in Member Collections
Our recently discovered Devonian Phyllocarid is back from our preparator. Found on Collecting trip 4/9/2021 in New York state (#3 Phyllocarids we have with complete mandibles). This rare specimen has the classic pyritized Roemerella brachiopods attached to its carapace and the detail of the carapace itself is well preserved. What I was hoping and had very little chance of being antenna are serrated hinge lines. I never seen this on other specimens and the detail is amazing under magnification. The pincher like mandibles look to have color or pattern markings near the tips. I'm pretty sure the jaws are in life position. Phyllocarids are not common and complete or nearly complete specimens is rare. The bite marks I see on some trilobites I find at the same locality may have been caused by these nasty looking jaws. -
the Most complete skull I’ve found to date. Both bottom mandibles seem to have all of the teeth and possibly only missing 2 premolars out of the top. Skull looks to be all there and possibly some other bones judging from some broken cross sections but who knows! I’ll upload more photos in the comments. The rock is 45.5 cm long 36cm wide the skull measures 26cm I’ll continue work progress as time goes she may take a while!
