Incredible Devonian Phyllocarid with Antenna New York
mikeymig posted a topic in Fossil Hunting Trips
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! -
I just took my Phyllocarids out of storage and put them back on display in the collection room. All of these extinct crustaceans were found in New York State. Two of the specimens have their complete mandibles (jaws) and all three Devonian Phyllocarids have their telsons (tails). The Silurian Phyllocarid from the Pittsford Black Shale is extremely rare. These are rare fossils and complete specimens are absent in most collections. They have been in boxes for a few years now and it didnt feel right keeping them in the dark. Most people that view my collection don't understand or find them interesting like I do. I like them so.......

Both carapace valves as well as the almost complete telson are present. The telson is wrapped underneath the carapace and one valve is underneath the other.

Last Saturday as some of you know, I found this really awesome Echinocaris punctuata with both valves and part of the telson. I had the idea of prepping it and then entering it into the IFOTM contest here on the forum. I’ve been working on it for 1 or 2 hours a day using pins and an old screwdriver. In this post I plan to post an image of the prep process everyday until it is complete.

I just received this "phyllocarid" valve from the Marjum Formation (Middle Cambrian) of Utah. It was sold as Canadaspis perfecta. It measures about 1" long and 3/4" tall. Although I don't have a compass, the angles between the hinge line and both the anterior and posterior margins of the valve look to be less than 100 degrees. Several papers I've read state that these angles are usually closer 120 in Canadaspis. Any thoughts on what this might be?

A tiny contribution to Paleontology
fossilcrazy posted a topic in Partners in Paleontology - Member Contributions to Science
The authors have just informed me, that a tiny Phyllocarid I sent them for study, was included in a recent publication of the Journal of Paleontology. (Collette and Plotnick, 2020 JP Gonatocaris) Part of growing from hobbyist to citizen paleontologist is helping our knowledge of fossils grow. It is always fun finding a fossil and then finding exactly what you found. The picture I included is one I took soon after finding it at Ridgemount Quarry. It is Late Silurian in age and found in the very same layers that Eurypterids are found.- 12 replies

Yesterday I was able to get out to Onondaga County in central NY. While I was there I got a chance to do some fossil hunting at two locations. The first was in Pompey Center, NY near Pratt’s Falls. The second location was a creek in Delphi Falls. The rock at both of these locations was the Skaneateles formation. I was able to get into a different formation at the second spot that was more shaly and had better preservation. This was my first time fossil hunting in the middle Devonian and I was amazed with the number of bivalves I found. (I’ve never found one in the lower Devonian near me). As well as bivalves I was able to find a few very well preserved gastropods, some brachiopods, a bunch of ostracods, and what I believe is a partial phyllocarid carapace.

Hey everyone! Back at it again. This time I’ll keep it a little shorter and get to the fossils. I made it back out into the field last weekend and visited DSR and Cole Hill on Sunday 3/29/20 with fellow forum goer @DrDave. Usually we shake hands on our hellos and goodbyes like any two people would. It was odd not giving the usual greetings with a friend and keeping distance during social interaction. Almost feels rude it’s a weird feeling. You almost have to say “sorry I can’t touch you” so you don’t seem rude lol. Unusual times we must adjust to. Anyway. At DSR I have been kinda working an area that has been rewarding me over and over. Either I’m working a productive interval OR I am simply working an area that is easy to flip slabs therefore yielding more specimens. To actually know I would have to dig seriously at different levels and see what I find. There was actually and obnoxious amount of talus on top of this and I had to rake with a purpose to get it cleared up. FIRST slab I pulled up....do you see it? Same picture zoomed in a little....see it now? Same picture zoomed in more...see it now? I wiped off some mud and took another photo....this is why phyllocarids get missed. They don’t really pop when you first find them. I scour every rock very carefully and even then they aren’t exactly jumping out of the shale. I’ve found some of my BEST specimens in other peoples garbage piles. I’ve have found spectacular specimens this way. I knew I had a beautiful Rhinocaris double carapace and I could see something curious sticking out the end but I wanted to clean it up before I made assumptions on my observations. I actually found several phyllocarid specimens on this day . I’m going to share some of the process I go through cleaning and cutting choice specimens and show the final results! stay tuned

Hello awesome people! Im finally out of hibernation . I don’t mind fossil hunting in the winter...as long as the snow isn’t deep. It’s been deep lately lol. So the winter hunts have been non existent pretty much. We finally had a good enough thaw and a warm enough weekend to make collecting possible! I went fossil collecting and fossil prospecting this past Saturday and Sunday (March 7th and 8th 2020). It was great getting back out in the field. what a sight!! The snow didn’t bother me I was happy it was well above freezing for once. South central New York tends to get more snow and it hangs around longer it seems ha. Anyway....I did a little exploring and was able to find more Eldredgeops specimens in a few different spots in the upper quarry. It seems if you want to find Eldredgeops you have to go to the upper parts of the quarry. Personally, I’ve only found 1 Eldredgeops cephalon In the bottom 2-3 meters of the quarry. Doesn’t seems to be any specific layers but more of an increased occurrence in the sequence. It would be interesting to try and track the shift in fauna to see if it correlates to a shift in lithology/environment. It’s a very noticeable thing that goniatites occur in the upper levels of the quarry as well. If I remember correct DSR has been described as having a coarsening up sequence in the literature. I bet extra analysis would support that idea. It’s a fun place to collect and get into deep thought about “how the heck did these fossils get here like this?”. It would be fun to try and collect/catalog data from DSR. It’s been a looong while since I made a detailed stratigraphic section. I always label my fossils (location+date) but maybe I need to start including elevation in the quarry....hmmm Anyway.....onto the AWESOME finds from DSR ........plus 2 small finds from a prospecting spot. scale bar used in specimen photos are all centimeter scale

I had a rough work week last week with Central New York experiencing major flooding. It forced me to work the weekend and kinda ruined my fossil hunting thoughts. I only worked half a day Saturday 11/02/19 so I took advantage of what little sunlight I had. I had to be home before 5 to go to the mall with my wife to return some soccer shoes.......married life lol. With travel time I figured out I could go to DSR and get 70-80 minutes to fossil hunt! I needed this to de-stress so I went for it . I didn’t get much time but I tried to make it count. I knew I wasn’t going to be doing any major digging due to the lack of time. My plan was to try and keep working slabs I pulled from the interval I keep finding phyllocarids. When I got there I saw a large area to the left of where I worked that was ripped up with slabs around. It was the same interval and layers as the productive ones I worked 30 feet away. I wish I recorded the moment because I literally said out loud “I’m going to find a phyllocarid in these discards”.......walked 2 steps and found this in the discard pile.... here is a field shot....I was excited and terrified cause I realized I just found a Rhinocaris columbina phyllocarid with both carapaces and the telson but the telson is on the counterpart!! I thought I was going to have another fish that got away story but then I finally found the other half after an agonizing 40 minutes. Remember I didn’t have long haha. here is a field shot of the other half. Telson top left. I got a call from work and I was literally on the phone working and fossil hunting when I found the other half and silently cheered then continued my phone conversation here is a photo of the raw uncut slabs I collected from the field. I have a saw now so I’m not as concerned with reducing in the field as I used to be. Here are some photos of the finished product. This is a really exciting find because of the amazing association of both carapaces AND the telson. Really an informative specimen. It also came from the same interval I’m finding other phyllocarids. The very delicate disarticulation of the one carapace and slight spread of all the phyllocarid parts makes me very curious about the paleo setting. This is a photo of an artists recreation of a Silurian phyllocarid I found on google. This is not a Rhinocaris columbina but it does have some similarities that will help people visualize what a Rhinocaris may look like. this little something I circled had me wondering if it was possibly associated with this phyllocarid. Almost seems like a little appendage but there is really no way of knowing for sure I suppose. Interesting either way. thanks for reading! Not a whole lot just a single find that I think is really awesome . A quick little DSR trip (11/02/19) with a nice reward! Al

Hey everyone! I finally had a day to go out and enjoy a Saturday fossil hunting with no time limit!! I decided to check 2 middle Devonian locations that have yielded nice dipleura specimens in the past. I’m still looking for “that one” specimen....eventually I’ll find one. I didn’t find the trilobite I tasked myself to find but I did find awesome stuff on Saturday . So here is a little trip report from Saturday September 28, 2019 plus some extra stuff I found earlier in the month. I’ll throw it in at the end. I got up really early so I could get to Cole Hill by sunrise. I had 2 sites in mind from the start. My new house is now only 30 minutes away from CHR which was a nice surprise! Early morning view I’ve had some tough outings at Cole Hill. This rock is so hard!!! I’ve tried clearing overburden just to get to more immovable rock. Anytime I get things moving I find something decent so that was the goal. Find rock that moves!! I ended up finding a spot way off the main outcrop and I got to work. I immediately found a plate with 5 cephalons!! It’s not being very photogenic so I took a picture after making them wet. the right shot shows 4 cephalons stacked in between the white scale bars....the left one shows the 5 hidden cephalon that Is under another cephalon. The bottom piece is just a cheek but could continue I’m not sure. Not very photogenic but rare to find an assemblage like that. I was able to find an area with more weathered rock and I found around a dozen cephalons!!! These are the better and bigger ones. I have a few nice juveniles but they are half covered in rock. I liked these 2 a lot. The left one is very 3D (also came in 10 pieces lol) and the right one has all the cephalon margins intact!! some nicer pygidiums I found. I found 7-10 total in various conditions. I found a lot of associated fauna as well!! The Gastropods came from mostly one bedding plane. The same spot I found the cephalon hash plate these were not far behind littered all over. I also found a bunch of bivalves! Way more than I usually do. I collected more on this trip than I have in the past. The rock kept moving and I kept finding!! After I worked the shelf back far enough I decided I wasn’t going to try and find a new spot. 4 hours of collecting and it was time to go to Deep Springs Rd. Even though I didn’t find exactly what I was after I found lots of amazing specimens compared to past trips . Kept my finder crossed that DSR would be as kind. DSR next post.....

Hey everyone, I had an entire free afternoon yesterday so made my way out to DSR and Briggs rd. I haven’t been out there since the group hunt and I was curious to see if I could find pickings to split. I did a good amount of slab tossing and I know others did as well. People also got some newer areas going also and I was curious if I could work off those too. I started the day at Briggs rd because I did so well last time I was there. I was drooling for a 2nd shot! I didn’t find anything top shelf worthy but I did seem to stumble on more dipleura than I did the last couple visits. These are the total spoils from Briggs rd. I don’t know how common dipleura is at Briggs or if they ever come complete but these are my best dipleura so far from Briggs rd. They sure don’t show up like the Eldredgeops lol. I just liked this cephalon lol. All alone popping out it the rock with great detail!! Basically I got a bunch of stuff like this. I did a ton of labor moving over burden so that perhaps in the future I can keep expanding the shelf I started. Kinda rough on the back but this overburden doesn’t remove itself! After a few hours I moved onto DSR to see what was left behind for me to find . With all the action at DSR with the group hunt something was bound to get missed!! I forgot to take pictures of the site when I was at DSR so all I have are the final spoils and some close ups of my favorite finds. DSR spoils I wasn’t at DSR as long cause I was so tired and worn out from Briggs rd so I didn’t do much slab removal or excavating. I spent most my time scouring over others discard piles looking for hidden gems! And gems I did find!!! I found this dipleura looking through some blocks that were pulled off the upper layer of the quarry. Dipleura tends to show up more in the upper strata. It’s missing the pygidium and the cephalon is tucked over. With some minor prep I should be able to expose the rest of the cephalon. Super happy about this find. In general I have been coming up empty with dipleura at both Briggs rd and DSR so it was a bonus. Last but not least....... Echinocaris punctata phyllocarid!!!! I found this just sitting out in the open face up. Most likely mistaken for a bivalve. I couldn’t believe it. My best phyllocarid carapace so far. It’s nearly perfect!!! I have to say this beats all my other finds for the day. Just sitting face up for me to find . Well that wraps it up. Fun time at Briggs rd and DSR with a couple exciting finds for me. Seems like every time I go out I comeback with something totally unexpected!! It just keeps me coming back for more . Hope everyone has a great mother’s day! Thanks for reading, Al

It's been about five months since I've been able to get out and dig, so when my collecting comrade and I arranged it, off we went. The weather was perfect, although it was muddy going. Spent about a day and a half at our site. Finds were not the best for some species, but the focus was more on site preparation. Pictured here are some Greenops widderensis. Both are missing parts, so will likely be in the grafting pile:
