After stopping at the Aurora Fossil Festival Saturday morning and attending a friends retirement festivities in Winston-Salem NC that evening, on Sunday I was up and on the road by 7 in an attempt to make it to Penn-Dixie near Buffalo NY before they closed at 5 so I could meet up with Devoniandigger (Jay). The GPS said it would be a 9 1/2 hr drive so it would be close, and as it happens construction on I-77 and elsewhere extended the drive so I arrived at 7 PM, too late to meet anybody. Fortunately Jay had helped me get a membership, so I felt comfortable walking around and getting the lay of the land before heading to a nearby motel. I was back at the gate by 6:30, and by the time I left around 11 (as I had to get to my parents place in Ontario that day) I was pretty worn out by digging up and splitting blocks of shale. Actually, I pulled the plug on that by 10 so I could wander around and score some nice brachiopods from the piles. The find of the day was a nice "piggy pile" (Kane's term, thanks!) of Eldredgeops, at least 5 and maybe more. I also grabbed a potential pair of nice side-by-side rollers, a couple of flattened rollers, what is possibly a piece of wood with lycopodish leaf scars, a smorgasboard of brachiopods, a nice Platyceras, and a small pile of solitary rugose corals. I will definitely be a return customer! Don

Found as surface float near the top of the Windom exposure, a few feet below the Genundewa Limestone at Penn-Dixie Quarry in Hamburg, NY. A very common fossil in Hamilton Group sediments. Similar to Emanuella praeumbona, distinguished from E. praeumbona by the hinge width; the hinge of A. umbonata spans the width of the valve, while that of E. praeumbona is narrower. A. umbonata has a nearly flat brachial valve, while that of E. praeumbona shows a convex profile. Full-sized specimens of A. umbonata are also not as large as E. praeumbona. Originally designated Orthis umbonata. A. umbonata has been defined as the type species of Ambocoelia by Hall. References: Wilson, K. A. “Field Guide to the Devonian Fossils of New York” (2014).

Found as surface float near the top of the Windom exposure, a few feet below the Genundewa Limestone at Penn-Dixie Quarry in Hamburg, NY. Distinguished from Ambocoelia umbonata by the hinge width; the hinge of A. umbonata spans the width of the valve, while that of E. praeumbona is narrower. E. praeumbona also shows a convex profile to the brachial valve, and grew to a larger size. E. praeumbona is common in the Hamilton Group only within the upper layers of the Windom Member. Originally designated Orthis praeumbona, later assigned to Ambocoelia, then reassigned to Emanuella in 1990. References: Hall, J. Palaeontology of New York v. 4.

From Indiana Jones... Grail shaped coral from Penn-Dixie King Arthur: Go and tell your master that we have been charged by God with a sacred quest. If he will give us food and shelter for the night, he can join us in our quest for the Holy Grail. French Soldier: Well, I'll ask him, but I don't think he will be very keen. Uh, he's already got one, you see. King Arthur: What? Sir Galahad: He said they've already got one! King Arthur: Are you sure he's got one? French Soldier: Oh yes, it's very nice!

I've been working through some material that my daughters and I collected on Sunday May 28, Digging with the Experts Day. While I feel like I'm pretty new to fossil collecting, this Mucospirifer seems particularly pretty and well preserved, so I thought I'd share(my pinky nail is 1 cm for scale): The original matrix surrounding the specimen is seen above. I assume there is some pyritization creating the gold color.

Hi from New York City My name is David, and I am a 51 year old physician originally from Rochester, NY. Since I was little, I wanted to be a doctor, except for about two years following a Rochester Museum and Science Center Field trip to the railroad cut in East Bethany NY, when I got hooked on fossils. I remember wanting to be a paleontologist for about two years in there back then (i.e. What did I answer to the question: "What do you want to be when you grow up?" From 8-10, I always answered "a Paleontologist"). But you know, you never completely lose that 8 year old kid's passions when you grow up. So recently I took my 15 year old and 9 year old daughters fossil collecting, including a couple of creeks on the western shore of Canandaigua Lake south of Rochester, NY, and then we went to Penn-Dixie on Sunday May 28th for dig with the experts. We brought about 50-60 lbs of material back from Penn-Dixie, and I have been working my way through it, cleaning up the better trilobites in the evenings after work. So I'm kind of hooked again.

Scolecodont fragment Length: Approx. 1 mm Upper Devonian North Evans Limestone Genesee Fm. Penn-Dixie Quarry Hamburg, NY -
From the album: Scolecodonts
This is the first scolecodont I ever found. When i first saw it under the microscope, I thought a passing beetle had dropped a piece of chelicera in my matrix! Only when I saw a second piece, still embedded in a limestone chip, was I certain that I had a fossil. I was correct about this being a chitinous jaw element. I was extremely incorrect about the age, phylum, and preferred living environment of the original owner! Size: Approx. 1 mm Upper Devonian North Evans Limestone Genesee Fm.

From the album: Scolecodonts
This is the 1st box in my display case, containing 3 scolecodonts. All of these specimens are around 1 mm long. Upper Devonian North Evans Limestone Genesee Fm. Penn-Dixie Quarry Hamburg, NY -
Back in early September, my husband and I went back to Penn-Dixie for another day of fossiling. I was particularly interested in collecting some North Evans limestone to search for microfossils, especially conodonts. Well, I'm not entirely sure that what I collected was North Evans (it might be Genundewa), but I've been slowly dissolving small pieces in vinegar ever since. I've seen lots of tiny weird things, probably foraminifera, with some possible echinoid spines for good measure. Tonight, I found what looks like a conodont to my admittedly inexperienced eye. Here are my 2 best photos (camera held up to microscope eyepiece): Is my identification correct? Does anyone have any further information on this particular piece? I'm excited!

I have a few dozen conodonts that I'm in the process of photographing and mounting for storage. Among my collection, I have several Polygnathus linguiformis examples. Last night, I mounted two P. linguiformis on my "Conodonts II" storage card. This one caught my attention: That pale growth on the underside struck me as odd, especially compared to the other P. linguiformis that I handled last night: So I went to look at the P. linguiformis that I'd previously mounted. Here are 3 of the 4 for comparison: I also looked at the page in "Conodonts from the Genesee Formation in Western New York" that shows a number of P. linguiformis for further comparison. While several show liplike growths on the back, none are quite as pronounced as the first specimen I showed here. I'd be curious to see what other collectors think about this set. Do I have a pathology, or is this an element from a really old individual?

Here's a piece from my Windom Shale (Middle Devonian) that I'd really like to identify. Anyone recognize it? I can think of two possibilities, and I'm not sure where to look to be sure. 1) Fish coprolite 2) Worm #1 seems more likely, somehow... I think this was preserved inside one of the tubular pyrite nodules that are common in this shale. Whatever it is, it's interesting! It's about 1 mm long.

I've been experimenting with breaking down some Windom Shale from Penn-Dixie, and I think I have some ostracods: I have a few other interesting bits, too. Are these echinoid spines, micro-belemnite bits, or something else? And then there's this object: That's a small sampling. I also have found lots of brachiopod pieces, which is not surprising. The shale is rich in macrofossils, especially brachiopods, trilobites, horn corals, and occasional straight cephalopods.

Found this trilobite on a small slate piece found at penn-dixie. I found a couple of greenops and phachops but the side spines look wrong for a greenops. Its very small this pic is from my digital microscope.

Got home and began inspecting the trilobites found at Penn-Dixie this past weekend. Found this head scratcher on the side of a slab my wife collected. Any ideas on ID?
