Devonian Bryozoa colony found, reassembled, displayed, resurrected.
mikeymig posted a topic in Fossil Hunting Trips
Atactotoechus fruticosus (Bryozoa) Kashong member, Moscow formation, Middle Devonian, New York Found 4/09/2021. Size - 6"x 4.2" This turned out better than I thought it would. When I find these bryozoa colonies, I have no idea how complete they are or what they will look like until I start piecing them back together. This colony is missing some pieces but a lot of it was saved from erosion/oblivion. The base of the colony was uneven so I used some modeling clay to help display it in its upright position. The last photo was my attempt to bring the colony- 14 replies

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!- 9 replies

Hello everyone, Some time ago I was talking about a gastropod fossil with an individual online who thought that it was an ammonite, During this conversation one thing was brought up that I have wondered about for a long time but have not actually been able to answer, and that is what exactly do we consider an ammonite? I have always thought that ammonites are the cephalopods with an external shell containing complex sutures which occur throughout the Mesozoic, but people have pointed out that certain sites talk about ammonites going back to the Devonian. I have always thought t

Several days ago I ventured to a Devonian desert locality near Superior, Arizona. I found the largest fossilized coral colony that I have ever found: 2 ft across. A giant Iowaphyllum nisbeti coral was covered over it’s entire length with several inches of a stromatoporoid sponge. I should have taken a photo, but it was not very photogenic; it looked like a white ledge in cross section. First photo is a piece of light colored Iowaphyllum nisbeti coral covered with a medium gray calcitic stromatoporoid coral that is about 8 inches across. The top of the coral is pointed up.

So still going thru items from my Deep Spring Road quarry dig 2 years ago. The ruler marks are mm. Below is a shell I "believe" is a bivalve. I think Goniophora sp. Any ideas please?

Help identifying Devonian fossils in limestone from Western NY
Rock-Guy-17 posted a topic in Fossil ID
I grabbed all these samples over the years from the same rock quarry in western New York, which excavates the Middle Devonian Onondaga Formation. I believe most of these are corals, but I was hoping someone could help specify what type of coral so I can organize them a bit better. I resized the pictures with the provided links to lower the quality, hopefully they are not too big still. Appreciate the help. 1. Two different fossils in this cherty material, on left I believe this is Rugose Coral because visible septa, but on the right above the letter "L" in the coin I am not -
This dolomite stone was discovered near Chasm Creek, central Arizona. It appears to have the fossilized impressions of raindrops splashing into a fine muddy surface. The stone seems to be dolomitic, as HCl causes a low fizz, unlike typical limestone's more energetic fizzing. Most of the "splashes" have the central "rebound" splash seen in my high-speed imagery of water droplets. That central rebound appears to have been broken off over time. Does my assumption that this is a somehow frozen-in-time rain shower make sense?

Freshly found. Found in/very close to Needmore Formation near Petersburg WV. More sandstone than shale, but shale was just above. Lots of brachiopods nearby. Would love someone to tell me it's a rare ammonite or similar. Thoughts? ID help? Thank you.

After some awesome advice from FF members, my family made it out to the Lost River quarry in WV (Devonian shale). We found a bunch of bivalve and trilobite partial fossils and two fossils that we can't ID (pics below). The first was found in a split piece of shale so one part mirrors the other (pieces are ~3x3in). Unsure if this is a fossil but any insight is appreciated! The second is a very small (1/4in) circular, striated fossil. Thanks!

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 intere

Microfossil slides and more tiny shark remains from the Devonian
fossilsonwheels posted a topic in Micro-paleontology
I finally got some microfossil slides and I got some additional Devonian matrix from New York. I decided to go back to the Genundewa Limestone matrix primarily because I failed to find shark related matrix from other locations that are of the same age. Each of the three searches in this matrix has produced different results which make it fun to search. This search was a lot of Phoebodus teeth and some were close to 75% complete. Easily the best Phoebodus teeth I’ve found in this formation yet. I found a fair amount of Omalodus teeth and some nice ones. I also found two incomplete- 5 replies

This was an oddity in my Dundee Formation material (Mid-Devonian) I decided to bring home out of curiousity. The material itself mostly contains white silicified fossils in sandy/packstone pulses with some grey crystalline chert horizons. The colouration of this piece, and its general shape, gave me pause as it seemed a bit out of place. Initially I thought, "possibly a fish bit?" (stout spinal process)? but the internal structure didn't strike me as likely. The specimen measures about 7 cm long. My second thought was possible plant material, but I am rubbish on plant identification in the Dev

Finally got back out to my site (Needmore formation outside of Winchester VA, early to mid Devonian) for the first time this year, very good feeling. Found, among other things, these 3 partial pygidium imprints. Two appear to be the same species, and I’ve found several other partials like these out here before. I know (or am fairly sure) I’ve seen this species before online but can’t place it. The third specimen I can’t place at all and as far as I’m aware, haven’t found out at this site previously. All specimens are a centimeter and change at most, can provide more precise measurements later

This fossil was found by a friend near Falls of the Ohio, so presumably Middle Devonian but who knows. The hollow elements are straight, with angular cross-sections, and seem to be organized in alternating orientations. Any and all insights appreciated. The coin is an American quarter dollar, about an inch (24.26 mm) in diameter.

Last Saturday we went on a new fieldtrip on one of our favorite hunting spots for Devonian fossils. Not a lot of fossils were found and the only large goniatite, although pretty at first sight turned out to be a nightmare to prep with little to no preservation further down in the nodule. On the other hand we had verry sunny day with nice views over the area and the first flowers taking advantage of the sunlight on the older scree piles. We also brought home a few small nodules with tornoceras fossils , they will take a while to prepp before we will see if they were worthwhile.

Some interesting finds in the field today, but this one made me wonder if this was a brachidium or some other related feature. It looks like a trilobite, so naturally I picked it up. The piece was long exposed to the elements. Length: ~3cm Age: Mid-Devonian (Dundee Fm, Ontario, Canada).

Hello, everyone, I could use some help with this odd little tabulate coral I found yesterday in an old gravel pit in southwest Michigan. I can't guess at a formation or age since it's glacial debris, but the things I find range from possible Ordovician (rarely) all the way to lower Mississippian. I think it must be either Devonian or lower Carboniferous. When I first picked it up, I thought it was just another type of Favosites, given the corallite shapes and what turned out to be large mural pores (towards the left) when enlarged: (EDIT: TqB has suggested parasite trac

This is a Late Devonian sponge collected from the Percha Formation found at the type locality on Brandenburg Mountain in Pinal County, Arizona. This sponge, has the largest complete head reported. Although mostly covered in calcareous sediments and maybe caliche it has the best preserved spicules of the species that I have seen; better than the photos in the Rigby reference below. First photo is a close up of the star shaped spicules that average 1 mm across. Second photo is of the top of sponge that is 70-75 mm across. First published in: Rigby, J Keith; Dietma

I was wondering if a complete or fairly complete placoderm skull/head has ever been found at Arkona? I am just curious as what this would look like, and because I have a few placoderm bits and pieces myself, pictures of such a fossil could possibly help me to figure out where these pieces came from. (This is mostly out of curiosity though because I know small placoderm bits are basically impossible to identify)

Lise found the first blastoid of the year at Arkona, during last weeks spectacular warm spell. She also found the first Petoskey stone, though there was very little of Lake Huron’s shoreline free of snow and ice. I, however, found a stromatoporoid. An interesting piece, from a chunk of armour stone, quarried from somewhere or other. A spectacular ice nugget was also found.

Back during an April trip to the Widder Formation (Mid-Devonian), I came upon a rather sizeable placoderm. It is very likely the arthrodire, Protitanichthys sp., although it is a bit of wastebasket taxon, but new research is underway. It was pretty much stuck in this rock, and it was only going to come out the hard way. I collected every little bit I could find from that dirty, messy bench, including the impression. Here is the in situ photo:

I was able to get out three times to three different local spots. Fairly underwhelming results, but it was nice to get back out in the field now that the snows have melted. The first two spots I had effectively tapped out last year, but it always pays to check in. The third one, featured here, was a new prospect. I had made a cursory visit last autumn, and then tried to jump the gun by going here at the end of February but the snows were still too deep. Exploring the Dundee Formation is admittedly a pretty niche focus. There is probably a good reason why it isn't the top destinati

On a recent fieldtrip I found a verry large and promising looking goniatite. The center of the specimen was covered in claystone. I tried a combination of mechanical prep with air scribe and treatment with potassium hydroxide. Removing matrix as close to the fossil as possible and then treating it with potassium hydroxide. I repeated this process a few times until I managed to clear out the whole center of the fossil. before and after pictures: Crickites sp. Frasnian ( Late Devonian) Belgium
