Here are the best prep results from a trade with Misha. Second & 3rd images: Back row, left specimen, Greenops boothi. In front of it, cephalon of Eldredgeops rana. Front specimen, pygidium (will try to identify later). Second row: brachiopods, one on left, Spinatrypta spinosa (renamed, will add new name to thread later on). The rest, thorax assemblages. Unfortunately, I couldn't get any of them to fit together. First image: rugose horn corals, other side of Spinatrypta brach. I will add the finest specimen in a reply to this post. Ran out of photo room. I w.

Hello there! This past Saturday, I went on a "field trip" to Hungry Hollow near Arkona, Ontario (mid-Devonian in age), and I found one weird item. It's an echinoderm of some sort, but which sort? A crinoid holdfast? Something else? Please see the photos below and let me know what you think. (By the way - I didn't make it home from work in time to take photos in natural light today, so I apologize for the fairly poor photo quality - if it's sunny tomorrow I can get better pictures then. And I also apologize for my blue finger in the photos - my students and I were looking at cheek cells under the compound light microscope today and some methylene blue got on my fingers - oops!) One end showing the pentaradial symmetry: The other end not showing much: Side photos: Thanks for your help! Monica

Hello everyone! I'm here once again to ask for some identification help as I continue to work on my fossil area display. Today I have a few items from Penn Dixie (Hamburg, NY, mid-Devonian) for you to look at. But before I show the photos, I was wondering about the formation that we find fossils in at Penn Dixie - is it all Moscow Formation? Okay, now on to the photos... Specimen #1: A Platyceras gastropod, but I'm not sure of the species: Specimen #2: A horn coral on the same rock as the Platyceras - is it Stereolasma rectum or Amplexiphylum hamiltoniae? Specimen #3: I've posted this one before, asking if it was a goniatite or a gastropod, but I'm starting to think it's a gastropod with some of the middle missing - perhaps Naticonema lineata or Euomphalus laxus? Specimen #4: A brachiopod and horn coral on the same rock as the goniatite/gastropod specimen - is the brachiopod Athyris spiriferoides? And is the horn coral Stereolasma rectum or Amplexiphylum hamiltoniae? Specimen #5: An unknown piece of something on the same rock as the goniatite/gastropod and the brachiopod - any ideas? Thanks in advance! Monica

Hi there! I'm currently writing labels for my Devonian fossils, and I was wondering if someone out there can identify the following Favosites coral down to species? It's from the South Pit of Hungry Hollow near Arkona, Ontario, Canada, and it's mid-Devonian in age. Thanks so much! Monica Top: Bottom:

Hello again! I have one more ID request (for now ). I received this Greenops as a gift, but I think I deleted the email which stated the exact location/formation information - does anyone recognize the matrix that it's on? And is it G. widderensis or is it G. arkonensis? I have a document stating that these two species have been found at Hungry Hollow (near Arkona, Ontario, Canada; mid-Devonian in age) - are there two different Greenops species found at Hungry Hollow or only one (widderensis)? Thanks so much! Monica I'll tag @Kane and @middevonian for this one

Spent 8 hours yesterday mucking about in the Hungry Hollow Member, resorting to that section of the Widder Formation as there are no viable upper Widder outcrops at the moment. Nothing fabulous in terms of finds, but the HH Member is temperamental... High turbidity makes for a lot of fossils that are not hardy to come out as a puree. Corals dominate this stratum, at times making up more of the composition than matrix. It also means not much in the way of reliable bedding planes as most of this stuff comes out in chunks delineated by the corals. It can also be quite muddy/wet, and hard to pick out what's there. When it dries, it is not much better. I didn't take much in the way of field pics. I did, however, see an abundance of salamanders, which speaks to some measure of ecological health in the area given that they are among the more ecologically sensitive critters. I struck my own spot by digging out a lot of soil and roots. The only field pics. Corals being by far the most abundant, some of them can come out quite large. These I set aside in piles for other collectors.

Hi all! Last weekend I attended Penn Dixie's Dig with the Experts event on the Sunday, and I found a couple of fossils that I'd like help identifying, if possible. The fossils are mid-Devonian in age. Thanks so much for your help! Monica Item #1 - photo of the entire rock and a close-up. Item #2 - photo of the entire rock and a close-up. Perhaps a crinoid bit?

Hello everyone! Viola and I spent about 2.5 hours in Hungry Hollow's South Pit (mid-Devonian in age) yesterday afternoon. The weather was actually the most pleasant it has ever been for us at this location, but it was so mucky from recent heavy rains that we couldn't explore the whole pit for fear of getting stuck. We did, however, come away with some nice finds. Most notably, it was my best day for finding the small pyritized goniatite Tornoceras - I collected 9, which is more than the sum total of what I've found in all of my visits prior to yesterday!!! I hope you enjoy the pictures Monica Two photos of the pit: Two photos of Viola collecting/playing in the mud: More to follow...

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:

Hi all! While I was looking through some of my fossils, I came across the specimen below, and I think it's a new little coral for me! Does anyone have an idea as to its identity? It appears to be a tabulate coral, but if anyone could let me know its genus and species then I'd be much obliged! It's from Hungry Hollow near Arkona, Ontario, Canada (mid-Devonian in age). Thanks in advance for your help! Monica

Took advantage of a break from the early wintry weather to go play in my fossil pit out back (London, Ontario), and came upon this. I'm sure this will be a cinch to identify, but i'm drawing a blank. It has ribbing reminiscent of an ammonite, but this was found in the Dundee Fm, Mid-Devonian, so too old for that. Ammonoids from around these parts don't tend to have ribbing like this, nor the appearance of nodes. I was thinking some kind of coiling gastropod. Too large and flat to be a Paleozygopleurid. If it is a gastro, I know how tough they can be to identify from a steinkern, but I thought I'd give it a go. As I'm one of the few on here who have access to Dundee Fm deposits, perhaps it is reminiscent to a similar Devonian formation where one of you collects. Does this seem familiar to anyone? Sadly, try as I might, I couldn't locate any other pieces from this rock, so this is all I have to go on.

Hello everyone! I'm sorry for the late reply in posting this, but I was busy on the weekend with a course I'm taking, so it took me a few days to get my act together. On Friday, October 12th, 2018, a bunch of TFF members met up at Penn Dixie Fossil Park in Hamburg, New York in order to do some group fossil-hunting for mid-Devonian trilobites and other critters. The members in the pictures that follow are Malcolm @Malcolmt (he's wearing the beige bucket hat), Greg @Greg.Wood (he's in the striped shirt), Ken @digit (he's in the red jacket), Ken's wife Tammy (she's in the blue jacket), my daughter Viola (she's the only child in the group, so she's easy to spot!), Kane @Kane (he's in the black shirt), Kane's partner Deb (she's in the black jacket), and Mike @ischua (he's in the blue touque and green jacket). Diane @Mediospirifer and her husband were there, but I didn't get any pictures with them - so sorry! - perhaps Ken got a few photos... I encourage the others members of the group to add pictures to this thread if they have any, especially pictures of the finds - thanks! Monica The group hard at work: Malcolm using one of his toys to clear off some dust and debris: Greg doing some heavy lifting: Malcolm splitting some rock: continued...

Hello everyone! This past Saturday, July 28, 2018, Victoria @VTinNorthAB and I met up with our families in Arkona, Ontario in order to do a little fossil-hunting together. It was a wonderful day - it was warm with a mix of sun and clouds and we all came away with some great finds! Please enjoy the photos below! Viola (my 7-year-old daughter) and Aviva (Victoria's 7-year-old daughter) in front of the falls at Rock Glen Viola and Aviva climbing a wall of Hungry Hollow's South Pit, searching for button corals and other goodies Adina (Victoria's 4-year-old daughter - it was her birthday!) and Aviva climbing the same wall - Adina was a trooper!

Hello there! I was able to visit Hungry Hollow's South Pit (near Arkona, Ontario, Canada - age is mid-Devonian) yesterday - boy was it hot!!! Viola and I spent three hours surface-collecting before we decided to call it quits and head to our air-conditioned car. We found our usual stuff, but I'd like your input on the following two items: Item #1 front and back: a type of Favosites coral - perhaps placenta? It's a lot flatter than my other Favosites finds, and you can even see what I think are some crinoid holdfasts on top, and an echinoderm plate (perhaps from a crinoid calyx?) on the back!!! Item #2 front and back: I have NO idea whatsoever!!! It's smooth, and I can't see evidence of holes/pores, but it is kind of hilly - what do you think? Thanks in advance for your help!!! Monica

Hello there! I visited @Malcolmt yesterday and he was nice enough to clean up some of my stuff from Penn Dixie (mid-Devonian), including the specimen below. I'm not exactly sure what it is, so I was hoping that someone out there will be able to help me with identifying this little guy, which I think is either a gastropod or a ammonoid - what do you think? These are all pictures of the same specimen, just from different angles. And it's pretty small - only 5mm across at its widest point. Maybe @DevonianDigger can help? Thanks for your help! Monica PS - We found a definite gastropod - a Platyceras of some sort - just barely exposed on the side of one rock, but it's kind of twisted and weird-looking, so Malcolm is going to work on it a bit more - after it's done, I'll post pictures of that little guy, too.

Hello everyone! This past Sunday, while I was at the "Dig with the Experts" event at Penn Dixie in Hamburg, NY, I found something a little different from my usual finds. I think it's a gastropod, but I'm not at all sure, so I was hoping for your input. The specimen is about 5mm in diameter, and you can see it in the eight pictures below - thanks in advance for your help! Oh, and the age is mid-Devonian. Monica @DevonianDigger - are these pictures more helpful? Thanks again!

Hello everyone! This past Saturday, Viola and I braved the cold to do some fossil collecting in the south pit of Hungry Hollow near Arkona, Ontario (Mid-Devonian). When I got home and washed up my specimens, I saw something interesting on one of the horn corals - I think it's a brachiopod - am I right? And does anyone know its identity? Thanks in advance for your help! Monica

Hello all! It's a dreary day, so I'm trying to organize some of my fossils into my new display cabinets, and I was hoping to get some help with identifications. All of the fossils below were found in the south pit of Hungry Hollow near Arkona, Ontario. The age is mid-Devonian. Thanks in advance for all of your help! Monica Photo #1: Definitely a coral, but which one? A type of Favosites, perhaps? Photo #2: Another coral - perhaps Alveolites goldfussi? Photo #3: Still another coral - perhaps Platyaxum frondosum? Photo #4: I have no idea what this brown thing is - help! Photo #5: A trilobite pygidium - can anyone tell which trilo? Photo #6: A brachiopod - no idea which one... Photo #7: Three brachiopods - again, I don't know their identity/ies Photo #8: Two brachiopods - I used to think they were both Devonochonetes scitulus, but up close they appear to look a little different to me - what do you think? Photo #9: The back of the rock from Photo #8 - any idea what those black fragments are?! Photo #10: A pyritized bivalve (thanks, Adam @Tidgy's Dad!) - again, I'm at a loss as to what its identity is Photos #11 and #12: A Mucrospirifer brachiopod, but I'm wondering - is that the lophophore that I see inside of it, or is it just the valve that's been crushed inwards?

Hello everyone! Yesterday, Viola and I were able to visit Hungry Hollow (near Arkona, Ontario), and we had a wonderful time! When we last visited the site back in April, it was cold and cloudy; yesterday, it was hot and sunny, and there were no bugs to bother us, so we were in the South Pit collecting fossils the entire time (about 3.5 hours). Unfortunately I didn't take many pictures, but I blame that on all of the fossils that were calling to me - they wouldn't let me take a break to take pictures! In all seriousness, though, it was a fantastic day out with my little girl - please enjoy the pictures I do have to share with you. Oh, and for those of you that aren't familiar with the rocks at Hungry Hollow - they are Mid-Devonian. Picture #1: Viola just before we headed into the South Pit Picture #2: Viola searching for brachiopods (as usual!) Picture #3: a spiny brachiopod - does anyone know its identity? @Kane Picture #4: a couple of "mommy and baby" Mucrospirifer thedfordensis (I think!) brachiopods - Bob O'Donnell found and gave the one on the right to Viola, while I found and am going to keep the one on the left so we each have one to remember our times together fossil-hunting Picture #5: a gastropod - Platyceras sp. - does anyone know the species name? Picture #6: I found my own Tornoceras sp. - hooray!!! Back in April, Bob found one and gave it to Viola, and I have to admit that I was a little envious because they're so pretty. Well, yesterday I found this specimen, and it's a really pretty shade of purple - I'm in love (Is the species name arkonense, by the way?) Picture #7: A coral with an epibiont on top of it - someone yesterday (I believe his name was Darren - he also gave Viola a bottle of water while we were in the pit - a very nice guy!) told me what it is, but I can't recall what he said. Any ideas? Picture #8: This is probably my favourite hash plate that I found yesterday because there is so much going on - bryozoans, corals, and crinoids - oh my! And perhaps a bit of a trilobite peeking out near the top...? Well that's all for now. I'll likely add more photos after we wash Viola's finds and look through all of our fossils more carefully. Thanks for reading! Monica

Hi everyone! I'm finally starting to go through some of the things that Viola and I found when we visited Hungry Hollow back in April in preparation of doing a trade, and I was looking for some help with identifying the following items: Item #1, front and back: A tabulate coral perhaps? I think I can see corallites in the "back" photo... (or maybe a bryozoan...) Item #2, front and back: Another tabulate coral? (or perhaps another bryozoan...) Item #3, front and back: A bryozoan? This one looks different - it kind of looks like frilly layers... Thanks in advance! I may end up posting more stuff so keep an eye out for more requests for help!!! Monica

Hi everyone! Well, Viola and I have officially expanded our fossil-hunting area to include Hungry Hollow!!! We joined in on a field trip organized by the Niagara Peninsula Geological Society this past Saturday, April 29th, and we spent 3 fairly cold and windy hours scouring the South Pit for fossils. Luckily, the pit's rocks are incredibly fossiliferous, so we came away with many specimens. Here are a few pictures of our adventure... Picture #1: Viola in the centre of the pit, looking for little things like brachiopods and bactrites: Picture #2: Viola at the side of the pit holding up her favourite solitary rugose coral: Picture #3: Most of our haul for the day: Picture #4: Some nice hash plates from the pit, mostly containing brachiopods and Tentaculites sp.: Picture #5: SO many rugose corals in the pit!!! Picture #6: A bunch of things, including brachiopods (Mucrospirifer arkonensis and others), crinoid bits, bryozoans, corals, smaller hash plates, and my favourites: pyritized bactrites: Picture #7: A pretty star-shaped encrusting bryozoan (Botryllopora socialis) on the side of a rugose coral: Picture #8: Some organisms on a Mucrospirifer arkonensis - perhaps a couple of gastropods or ammonoids, a bit of encrusting bryozoan, as well as a couple of tiny ostracods (maybe): Picture #9: An Eldredgeops rana cephalon (partial): Picture #10: A trilobite pygidium - it's orange and oh-so-cute!!! I have to thank @Bob for showing Viola and I around the pit, and telling us about the fossils that we were finding - he was an amazing help!!! We had such a great time - hopefully we'll be able to visit again soon!!! Monica (and Viola)

Leaving this afternoon to go to White Have PA to see my 1 daughter and baby grandson, and staying the night. Going to look for some quartz crystals at White Haven, that's where she lives. Then in the morning I have to be in East Stroudsburg PA for some business and after that's done I'm going to Beltzville State Park. I've been wanting to go there for the last 2 months or so but it never worked out. Now it does and I'm going fossil hunting. I'm excited about it! Plus while I'm driving I'll be on the lookout for some interesting road cuts. Can't wait! I'll post pics of my finds later in the weekend and let you know how it went.

I have a fossil that I found that I don't know what it is. I found it in Perry County PA. It's Middle Devonian, limestone & shale mix. The fossil itself is a little bigger than a half dollar. It kind of looks like maybe an anenome, maybe? I would appreciate any and all help. Thank you!
