Hi, I found this fossil along the Thames River in London Ontario. The area I'm in is part of the Dundee Formation which is Devonian. Can anyone identify/confirm if this is a Favosite coral? Thank you!

I found this fossil sea urchin in Ithaca, NY in a layer of Moscow Shale (~400 MYO). I'm trying to figure out exactly what this is, and I think it might be an archaeocidaroid. The earliest published cidaroid is ~260 MYO (J.R. Thompson, et.al. Scientific Reports, 2015). I don't think this one is a euechinoid but i suppose it could be. Any feedback would be appreciated.

The last few fieldtrips didn’t deliver a lot of fossils, so now I got time to get started at my backlog of fossil preps from the Lompret quarry. I still have well over 100kg of material to sort and to prep from there. Last weekend while rummaging through a few of those boxes I picked up one that got my interest. A Fragment of a large nodule with a part of a nicely sized Gephuroceratid poking out. After a good look, there were a couple of other fossil fragments visible in there, sadly the matrix was extremely hard. I had to use a grinder and hammer and chisel to get through it, the problem was that apart from the few visible specimens I was grinding in to it blind, so It happened that I grinded through a few fossils that weren’t visible on the outside. But from time to time I was lucky and exposed a few more fossils, including a nice small pyritized Manticoceras. After that I got the specimens out, I used a grinder to go over the matrix and used colour deepener on the fossils, this gives a nice colour contrast between the fossils and the matrix. The fossils visible on the finished piece are: a few Gephurocertids like Manticoceras sp., a little Tornoceratid, a Bactrites sp., a fragment of a nautiloid orthocone and a brachiopod Ryocarhynchus tumidus. The piece is from the late Devonian, Frasnian, Matagne formation near Chimayin Belgium. A goniatite poking out Grinding, chiseling and airscribing... almost done: All cleaned up picture with scale:

Last weekend we went on a field trip with the geology club of Ghent to a quarry in Southern Belgium that we hadn't visited before. The deposits in the quarry were mostly Givetian and Eifelian, but only the Givetian layers were exposed. The rock was a massive limestone, whit from time to time some fossil remains from reef builders. but most of it was impossible to extract. So at the end of the day we had nothing to show for. The only notable finds were calcite cristals, but we gave those away since we don't collect minerals. You can't score every time , Still a fun field trip though, and an impressive sight to see almost vertical sedimentary layers.

Fossil hunting trip to Hotton (Devonian of Belgium)
ziggycardon posted a topic in Fossil Hunting Trips
Hi everyone! Last saturday we went on a fossil hunting trip with the BVP to Hotton in the Belgian Ardennes. https://www.paleontica.org/locations/fossil/667 There were 2 different locations planned for the day, the first was the "Carrière de Marenne" quarry in Hotton were we spent most of the day. It was my first time at this location, so I didn't have very high expectations but we were very pleasantly surprised by the quality and quantity of the finds which made for a very productive and succesfull trip! Unfortunately like so often I forgot to make pictures inside the quarry... So it will mainly be a report of the finds rather than the excavation. The age of the layers date back to the Givetian stage of the middle Devonian which lasted from 388 million years ago to 383 million years ago. There were 3 spots inside the quarry were we searched for fossils. We started on the east side of the quarry where we found some weathered corals, a bivalve and some bryozoans. One of our friends was very lucky when they found a fragment of Placoderm bone.. the 2nd spot we searched was still on the east side of the Quarry but this time near the big rock outcrop which devides the quarry in two pieces. Here we all hit gold as this was a large area where it was full with weathered fossils in great condition ready to be picked up! No need for hammers here, just grabbing which was laying on the ground as it was littered with corals en brachiopods. We almost collected a bucket full from this area alone. The 3rd spot was the west side of the quarry which was divided in multiple levels. I mainly searched in a large rock pile with some others as it seems these were the remains of an ancient coral bank. We found many large corals here like Hexagonaria and Favosites as well as some nice mineral specimens to much delight of my girlfriend. Someone did do the find of the day here when he found 2 extremely large Stringocephalus brachiopods. I also went with Tom, our group leader to prospect the rest of the quarry but beside some corals I didn't find much more things of interest. At the end of the trip we were given some nice mineral specimens by Tom who found some on the lowest level of the quarry which we didn't visit ourselves. Here the only photo I made inside the quarry, were my girlfriend was building a rock fortress. (Everyone was on a one hour break due to the early summer heat) And here are our finds from inside the quarry: A large Hexagonaria sp. coral which we managed the haul home, one of the perks when you bring a wheelbarrow to a quarry! Another nice Hexagonaria sp. coral And our 3rd large piece of Hexagonaria sp. coral One of the Favosites sp. corals we brought home. Another Favosites coral An our chuncky Favosites coral A weathered Hexagonaria coral. A bivalve we found early at the beginning of the search.

Hey everyone, I have this fossil I found along a beach when I was a kid. Unfortunately, I have no knowledge as to where I found it, other than it was an Ontario provincial park. I suspect it's a fish fin from either the Silurian or Devonian, but I want to get the thoughts of someone who knows more on fauna of this time. Thanks! Ps. There's a little something on the side of the rock that may help with id, it's in the second pic. Looks to me like a part of a plant.

A couple weeks ago I took a road trip along the entire border of the lower peninsula of Michigan. One of the days was spent collecting Devonian fossils around Alpena. I visited four sites and had a lot of luck, finding dozens of crinoid calyxes, a couple trilobites, and many other interesting things. It will take me a while to sort through everything, but I did finish cleaning up finds from one of the sites and wanted to share. Nothing groundbreaking, but all good finds for me as I rarely get to collect in the Devonian. The coral Trachypora sp. A partial Dolatocrinus calyx encrusted by a bryozoan A partial crinoid holdfast A partial Dolatocrinus calyx (top left) and some plates from a Megistocrinus calyx (center)

Hello everyone, This weekend on Sunday my family and I made a short trip out to Central NY to do some fossil hunting. I was planning on doing this on my actual birthday which was on Monday but due to the weather we decided to do it earlier. As a result the trip ended up being more spontaneous, shorter than expected but still very enjoyable. The first stop was DSR, this was my second time at the quarry and although I didn't get as diverse of a selection of fossils this time (probably just being more picky), I got some nice specimens of a few new species as well as ones I already had. Here are some highlights: It was a great day for Spinocyrtia granulosa, lots of specimens, a number of complete ones. I especially like two of these This one is complete with very nice preservation and it's quite large. This one is the largest specimen I've seen. It's only one valve but in width from the wing tip to the end it measures right around 7cm, had it also had the other wing tip it would probably reach around 8cm. It also has some kind of borings around the commissure, I assume these occured after the animal died and the shell disarticulated, although I am not sure what kind of organism this comes from. I really love specimens like this as they tell such an interesting story of this long gone environment. Found a few nice Athyris spiriferoides, I really love these brachiopods and was excited about that. They were quite common this time but for some reason last trip I didn't collect a single one. A pretty nice, complete Mediospirifer auduculus This specimen I was very excited to find, I am not 100% sure but I think it might be Eoschuchertella arctostriata? Very beautiful in my opinion this is only an impression but I don't have any other specimens so I thought it was worth keeping. I believe this is Hyolithes striatus? Found a number of nice bivalves This slab has an Athyris and two bivalves, Pholadella radiata I believe Doesn't show up to well in the photo but this was a pretty nice Retispira leda I found I think this is Pleurodictyum americanum? Corals seem to be pretty uncommon here, and I don't have any Pleurodictyum in my collection so I was excited about this one. This last specimen for today left me confused, I found it exposed on the surface in pretty much the same condition it's in now. What confuses me is that the form of preservation looks very much like that seen in many lingulids, shiny black shell material. And the growth patterns also could fit that, but I've never seen any of this size or shape from DSR, so I was wondering if maybe it's some kind of bivalve, I'm really not sure with this one. I'll likely split this off into a different ID post with some other stuff later. I'm still sorting through and photographing the finds so I'll definitely update this topic more.

A few weeks ago I went on a fossil hunting trip to Albany County. I was hunting in the New Scotland formation which is lower Devonian in age. It was very quick and easy to collect in and the dry dredging technique was quite useful. The rock was a very thin shaly limestone which could break easily but many of the fossils had been silicified, making it easy to pop them out of the rock. I found many different species of brachiopods, some gastropods, lots of corals and large bryozoa and a few trilobites

Good evening to everyone who comes to see my post, I thank you in advance for the time you take to read the question you presented, which would be the first of several specimens that I have not been able to identify. About two years ago I started hunting for fossils almost by luck as I was looking for minerals until I found the first turritellas, on one of these trips I find a rock of considerable size and weight with a curved linear pattern similar to "worms" although I honestly don't really know what it is, I have found trace fossils but never horizontal, and less than that thick, I have found specimens of what could be crinoids (or belenmites because of their shape) and a lot of unidentified things due to the large conglomerate in which they are found, what I have been able to identify are trilobite tails and spikes (perhaps), all this separately, never a complete specimen in a type of black rock with a slight percentage of pyrite, a stone very different from the "worm" specimen, which is more of the sedimentary type - quartzite when sectioning this stone to see if other specimens were found in any other layer of this stone I have only counted 2 or 3 oysters of about a centimeter. I found the rock in a river where apparently there is an exposed rocky stratum and in the seasons of crescents they go down with the torrential river. I have found other stones with total conglomerate of oysters others assorted with trilobite tails and oysters and shiny clams, and the aforementioned type of black rock beautifully preserved i have never found a complete trilobite specimen (if this helps in identification) the rocks come down from one area called "eastern mountain range" in Jujuy, Argentina, where several things related to trilobites and a species were discovered (connoisseurs will recognize Jujuyaspis keideli Kobayashi (1936). For the rest, I cannot provide more information since I do not know the real location where this rock came from. I attach the images of the specimen. The rock measures more than 40 centimeters and weighs something around 2 or 3 kilograms. All the best. Thank you!
