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:

I went back to Deep Springs rd last weekend. It was my 2nd time there. I couldn’t sit around on my Saturday off and do nothing lol. Fishing season doesn’t start till April 1st so March puts me in this odd limbo of waiting for the fun to begin. Now that I know how to get to DSR no problem and I live so close I will probably visit several times this year. It’s a really fun site for diversity. I want to see how much I can find and catalogue. Perhaps in the future I will make a little personal reference guide for DSR. Anyway. Pretty sure I found my first phyllocarid carapace this past weekend. It’s not much but I find it to be pretty cool. I have a phyllocarid mandible I found in the wanakah shale in Buffalo so it’s fun to try and find more of the animal. This is the part and counterpart of the larger specimen. I only have a scale on 1 but they are the same specimen. This is the smaller one I found with a scale. Im a big fan of these goniatites that come from DSR. I got a decent one last trip.

Anyone intimately familiar with Phyllocarid morphology? This slab is from a lower Devonian formation in the northern Yukon Territory. These things were giants ... The well preserved Telson (tail-spike) piece is 10" long, the feeler/antennae assembly alone is 18" long ... In life the critter was likely a good meter in length. What I'm not certain about is the 8" long arm-like appendage at top, as well as a small armor like plate nearby. Over the years have found many complete trident shaped telsons and antennae but not much in the way of other body parts.

A very rare Phyllocarid from the Pittsford shale. You can see other Silurian arthropods (Ostracods) scattered on both halves of the Phyllocarid. How good are you with Phyllocarids? I collect Devonian Phyllocarids from New York but this is my first Silurian Phyllocarid. All the research I have done tells me that this is likely Ceratiocaris but I want to be sure. Please chime in. mikey

I spent the day Friday hunting for Eurypterids. I was pleasantly surprised when I found what I believe to be the tail and last segment of a phyllocarid. Definately looks like the picture in my book "Fossil Ecosystems of North America" This was found in Bertie Dolestone of the Williamsville formation. This is late Silurian in age. Based on the commonest phylocarid in this formation being ceratiocaris acuminata, I suspect that is what I have here. The tail spike appears to be adjsacent to the last segment which is outlined with a black fine sharpie. The tail section itself is 67 millimeters in length. Basically unprepped just a quick dust to get some of the crud off. Here is a close up of the tail Here is a diagram I found
