  1. Bactrites sp.

    I've been cleaning up a few boxes with devonian fossils from the past few months and came around this nice little fellow. I cleaned him up and gave him a paraloid treatment to preserve the pyrite. It is a complete specimen of a Bactrites sp. from the Matagne shales ( Frasnian, late Devonian ) from Belgium, both phragmocone and body chamber are preserved. They are a little unusual, as the do not belong to the nautiloids as his first appearance might suggest but they have their own subclass and are considered to be the ancestors of the ammonids ( they have a ventral syphuncle like all the ammonoids ) Fragments of them often pop up from the shales, but I rarely find them complete. This one is going in the display cabinets
  2. Devonian cephalopod collection

    I finaly got around putting all my best cephalopods specimens that I collected over the past 4 years in the frasnian of southern Belgium on there place in the cabinets. They all come from the same location. (except an orthocone and a receptaculites from the same age but from a different spot ) most of it has already been posted in individual posts, but this gives an overal vieuw of the part of the collection on display. Enjoy al the Manticoceras, Crickites, Tornoceras, Bactrites, Orthocones and more
  3. Last weekend we made a trip to my favorite Devonian hunting spot. As usual we found a few goniatites, but apart from this we found a lot of smaller fossils like brachiopods, crinoids and even a bivalve. and a few other nice surprises. The small bivalve: glyptohallicardia sp. 2 valves and pyritised, only a few mm wide with bot halves preserved. a very nice crinoid calyx a tiny brachiopod ( Lingula ) One of the best finds of the day was a fish tooth, I’m still unsure on the species, but I think something in the area of a Euchondrocephalid like Helodus. It the my oldest tooth in my collection Still, I did find an even better fossil , I’ll let you speculate on what this might be, but for now it is packed in the trunk of my car and I’m going to drop it off to the local institute Halfway on the way back home we spotted a construction site with a little bit of chalk coming out of the ground, we stopped for a prospection and came back with a few incomplete echinoids and 2 belemnites . So it is always worth to stop at an interesting looking spot
  4. Today we had a field trip with the "Lithos" geology club at my favorite hunting spot. Although the day started with freezing temperatures, the sun quickly rose the temperatures during t morning and gave us a beautiful day. the last time I visited the quarry the finds were disapointing due to the lack of activity in the quarry, but today we were lucky and the past week a new acces road was being dug to the side of the quarry, straight through the Matagne slate. It didnt take long before I found my first fossils, at first a few halve goniatites, but after a while a complete large specimen and a nautiloid that I had never seen before at this locaton. we searched further in the quarry where we found the spot where the rest of the slate was dumped, resulting in a couple extra goniatites, one of them was an exquisite specimen and a 2nd nautiloid. Note that al the goniatites this time weren't Manticoceras specimens, but an other Gephuroceratinae: Crickites sp. they differ from the former with a more bulbous shape and large size ( up to 30cm in diameter ) In the afternoon we prospected the usual scree piles at the back of the quarry where we found a multitude of small pyritised cephalopods and I even found a broken nodule with very rare placoderm remains. Natalie also found a large and complete Crickites sp. at this spot This day turned out to be one of my most productive days at this location.
  5. Big manticoceras prepp

    Yet again a Manticoceras prepp my last few preppjobs were very succesful, and inspired by what @Ludwigia did on a larger one that I sent him, I tried to prepp one of my larger Manticoceras specimens. I tried a few new tricks to prepp this one, although the living chamber got dammaged, I decided to remove even more of the living chamber to show more of the inner shell with suture lines. It turned out quite well: Manticoceras sp. diameter 16 cm Frasnian ( late devonian ) Chimay area ( Belgium ) as found: ( top left specimen ) removed from the large chunk of matix: ( and glued back together, not everything went acording to plan ) during prepp: the end result:
  6. lucky split during preppjob

    This week I've been prepping a few goniatites that I had lying around. This one didn't look very promising, but what a surprise I got when I tried to remove it from the matrix. a few hits with the chissle and it came out perfectly. I just had to remove the extremities and clean out the center with an airscribe. It turned out to be one of my best specimens Yet an other Manticoceras sp. for display
  7. I've always wanted one of these and it's just arrived! I spotted it on the usual auction site where it was being sold by an antique seller as a possible fish in slate . It is true slate but is a legendary Delabole Butterfly, a metamorphosed Cyrtospirifer extensus, almost certainly from the Delabole slate quarry in Cornwall, UK. Although quite famous and widely referred to, there's not that much solid information. They appear to have been sold to tourists, largely in the 19th century and this split specimen seems typical. I think they're quite rare though - most photographed specimens seem to be in museums. Many years ago, I wandered around the edge of the quarry and managed to find one small fragment in the waste. Devonian, Frasnian, about 4" across. ,
  8. Prepping nodules with Bactrites

    Although the most pieces of my collection are goniatites, I am more than happy to add other Devonian cephalopods to my collection from time to time. On my last field trip for devonian cephalopods I splitted a few nodules and some of them had a few uncommon fossils in them: Bactrites I rarely find decent fragments of them, but those few were looking promising. Bactrites, although they look like an orthocone are in fact straight Ammonoids and not a Nautiloid. the septas start to be slightly ondulated, but most important they have a ventral siphuncle, a typical trait of an Ammonoid. the first nodule had a fragment sticking out, and when I split the nodule another one was found inside. I kept both parts of the nodule and prepped the one inside and on top After prepping them I found out that neither of those were complete, but the were decent in size and well preserved. The second nodule on the other hand hand was much better, a piece of the Bactrites was sticking out from both ends of the nodule, so I new I had a complete specimen. The prepping was relatively hard as different parts of the cone had different forms of preservation, but in the end I got the whole specimen out of the matrix and is my best Bactrites until now. enjoythe pictures: 1st nodule with the specimen inside: after prepp: After prep with the top of the nodule containing an other fragment. prepp on the 2nd nodule: after prepp, with the different kinds of preservation visible: and the whole lot:
  9. polishing some of my Goniatites

    I recently got a new job, and to make things even better, my job is at a company who processes and places floors and walls in stone, mostly marble. This opened a few opportunities for me , having access to a huge amount of polishing and cutting tools, so this week I gave it a try: I took 2 of my Goniatites that weren't of top quality, or to hard to prep. and today the helped me to cut the fossils and polish them. The fossils turned out really well here are my first 2 polished Manticoceras sp. from the Frasnian layers of Lompret in Belgium: before polishing them: after cutting and polishing: top goniatite: Bottom Goniatite: both of them: And a question for the moderators: the fossils have been cut and polished today, but were found earlier this year, are they valid entries for FOTM since al the cleaning , cutting and polishing was done now? Thx Kevin
  10. Devonian BBQ

    Yesterday I visited my favoriet hunting spot with a few friends. Since the weather forcast was realy good we made sure to bring a portable bbq, meat and drinks. Me and my girlfriend were the first at the location, we made a quick prospect for devonian cephalopods, but there hasn't been a lot of activity in the quarry since our last visit. Once the group was complete we tried our luck in older parts of the quarry, but only a few cephalopods were found. At lunchtime we set up our little bbq and equipment and enjoyed our lunch ( this was fossil hunting in style ) the afternoon we continued our search for fossils. only one extra large goniatite was found by a friend, on the other hand, my girfriend made an exellent discovery, she found a large piece of placoderm that is likely to belong of the same specimen we found last year, it wil soon join the rest of the pieces that are being preped at the museum now. On the way home we made a quick stop for prospection in an other quarry, but appart from a few nice calcite cristals we had no luck here. Still, we had a realy fun day one of the 2 goniatites I found that day: Lunchtime Hexagonaria next to the BBQ: the placoderm fragment found by my girlfriend ( Natalie81 ) The large goniatite of my friend calcite crystals from the next spot:

  12. Last saturday my girlfriend and I went back to the south of Belgium to go hunt for my favorite fossils. On the way there we saw a new road under construction where cretaceous chalk was visible. We made a quick stop to chek it out, but we only found 2 bellemnite fragments. So we hit the road again to the devonian rocks. The weather was quite good for this time of the year, so it was no suprise to see some fellow fossil and mineral hunters on the site. Some new heaps on the side of the field got my attention. Here I made my first good find of the day. A goniatite anaptychus. I was missing this in my collection. So I was verry pleased with it. The rest of the morning most of the finds were made in situ by Natalie, 2 decent sized Manticoceras and 2 Carinoceras specimens. She also managed to find a trilobite fragment. Also the first trillo adition from this quarry to our collection. At noon we were joined on our hunt by a friend. We then got to the large dirt pile at the end of the quarry whera a few other people were looking for smal pyritised cephalopods. After a few chats with the other fossil hunters about the cephalopod fauna the showed me a huge Goniatite they found earlyer that day. I had rarely seen a specimen like this. My surprise was even greater when they offerd this specimen for my collection since I specialise in this kind of fossils. Again lots of thanks if that person reads this thread, it wil get well deserved attention and preparation. The rest of the day we spent on the large mound picking up various fossils but my find of the day here was a incredible crinoid calyx. The trip turned out to be one of my best on this location. Cheers. Manticocerasman I'll upload the photos in the next post
  13. Specimens of corals from the Devonian limestones of Devonshire in England are hard to come by nowadays - this is one I've just bought and repolished. It's likely to be a 19th century sample from when the quarries and marble trade were flourishing - many such pieces were sold then as scientific specimens, and many more were used decoratively. Frechastraea sp. , Givetian/lower Frasnian, Torquay area. The brass scale bar is 1cm long.
  14. Late Devonian Lungfish teeth from Lithuania

    Dear Guys, I noticed many different forms of Lungfish dental plates in my collection, especially from Late Famennian dolomites from the Zagare quarry. Please help to identify genera of these teeth, if you cannot do it then please help to find a specialist on this type and age of remains if you could. Best Regards Domas
  15. Late Devonian fieldtrip

    Last weekend was a fieldtrip to my usual spot the late Devonian in the area of Chimay in Belgium. And of course hunting for the prized cephalopods. Althoug the usual deposits are depleted due to the activity in the quarry, there are now new deposits that can be prospected. A lot of Matagne formation is now exposed, here a lot of small but wel presereved fossils can be found , mainly brachiopods, but in the correct layer and with a little patience a few pyritized cephalopods can be discovered, mainly: Bactrites sp. , multiple kinds of Gephuroceratina ( Manticoceras..) and Tornoceras. The day was cold, rainy and even a few snowflakes, but it was wel worth the trouble. Thx to Anthonie Hellemond (President Belgian Paleontological Association 2018) for the pictures in the field ( and the extra goniatites ) Bactrites: Manticoceras on bottom and a little Tornoceras on top. Oh and in contrast to all the little pyritised fellows there was this one ( also credits to Anthonie for the discovery ) It wil take a while to prep .... Cheers, Manticocerasman
  16. Today I went to the "Belgian institute of natural history" to donate my placoderm that I found in Oktober. It is verry likely that it is a new species , but only time will tel. The local placoderm specialist wil work on this specimen for the description. Here is the link to te 1st thread on this topic:
  17. Devonian cephalopod plate

    A few months back I managed to get a whole piece of one of the layers that delivered cephalopods. I took the whole rock back home spotting only a few posible cephalopods. After the prep work this is how it looked in the beginning: multiple Goniatites and orthocones on 1 plate: ( Manticoceras, Sphearomanticoceras, Orthoceras ) Late Devonian ( Frasnian ) Chimay area ( Belgium) after a little work:

  19. Weathered crystallised goniatites

    I promised some regular posts from my collection in the weeks to come, so for this week I got two particular goniatites I like to share. Both specimens are weathered, but reveal some beautiful crystalisation of the chambers. Especialy the large one where they even form small calcite geodes. 1st specimen: Manticoceras sp. Frasnian Chimay area ( Belgium ) 2nd specimen: Sphaeromanticoceras sp. Frasnian Chimay area ( Belgium )
  20. Arizona Devonian Stromatoporoid

    I collected these silicified stromatoporoids from the Devonian, Frasnian Age, Martin Formation north of Payson, Arizona. The spires are 2-4 mm high and have bases 1 to 1.5 mm wide. Hexagoneria and Pachyphyllum corals occur with these. The first photo may be a difference species from the last photos since the spires are lower. Any idea what species these stromatoporoids might be?
  21. Last weekend I had again a field trip to my favorite location in the area of Couvin. We went to the quarry with a geology club, around 20 participants came to the meeting point. Everyone got a quick briefing of the geology and paleontology of the quarry and the usual safety instructions before going down in the quarry. Once at the interesting spot we noted a few changes: a pile of gray nodular limestone was freshly excavated. In those boulders a few of us found large well preserved goniatites. I had the chance to find a nice one from around 8cm in diameter. After a careful examination of the boulder I went on top of the quarry to dig out a layer yielding small cephalopods ( orthoceras, manticoceras and bactrites ) I had to dig whit a heavy pickaxe, but I was able to clear a decent part of that layer for me and a couple of the other searchers. The hard work paid off, I found around 20 goniatites and a whole bunch of orthocones, most of them are waiting for a cleanup and prepwork. While leaving the quarry I saw a piece of shell sticking out of a stone, a lucky split of that rock turned out to reveal a large Goniatite with beautiful suture lines. This one will require some extra prepwork, but it looks very promising.
  22. Devonian Belgian cephalopods

    It has been a while since I made a decent post on this forum ( spending most of my time here in the chatroom ) But last weekend I took the courage to prep some of my recent and older finds. In my older posts you could notice that I’m particularly interested in the Paleozoic fossils of my small country, especially if I can get some cephalopods. Although they are relatively rare here, we found a few deposits wielding them, and in the quarry of Lompret a specific layer has been really productive for them. Their conservation isn’t always very good and they might be hard to spot, but this I a selection that I made and prepped. I hope you enjoy them as much as I do. https://goo.gl/photos/s1N12Vic27d49GUb9 This one had a little surprise during the prep, while clearing the goniatite I discovered a small orthocone under it. ( Manticoceras sp + orthocone: might be orthoceras or Bactrites ) https://goo.gl/photos/Ek4BYCRckhLBxNWP7 Manticoceras sp. https://goo.gl/photos/hw1LotmNF4KzxCyp6 Multiple orthocones, the largest one judging by the position of the siphuncle should be an Orthoceras sp. https://goo.gl/photos/thc9WLxVT6zWgrTC8 Manticoceras sp. https://goo.gl/photos/bS4EniPSXf1miQVEA This is one of my favorites: a double Manticoceras sp. https://goo.gl/photos/exfdSJ2X1XzFtMy78 https://goo.gl/photos/oFvCtRKuWauJtKwL8 This is probably the best one in my colection: 3 complete Manticoceras and a partial one and a Orthocone. ( that last wan came loose during the prep and was glued back in position. ) I realy like the tiny specimen in the chamber of the larger one Cheers, Kevin
  23. Yet another fieldtrip to the late Devonian (Belgium) Last Saturday I organized with my pall Anthonie, a field trip for our Paleontology club. The location was the quarry in Lompret, here they exploit the hard limestone from the ancient Devonian reef ( Frasnian deposits ) On the top and sides of this reef we find softer deposits from the lagoons around it. The trip to the quarry rainy, as usual from the past few weeks, but et the location the clouds were clearing up. We waited for the whole group at the meeting point, and once complete we headed into the quarry. Here we made our first stop, explaining the geology and paleontology of this area and repeating the security measures. After this the group split in 2, the hardcore collectors went down in the hope to find an elusive trilobite an I took the rest of the group to the top where most fossils were commonly found. Once I found a decent spot I made a small review of the fossils that could be found and the people started looking around. Quickly the first corals and crinoid stems were found and sometimes a brachiopod or a gastropod. After helping anyone finding their way in the quarry I started to look for some nice specimens myself, and secretly hoping to find some cephalopods. The whole morning was quite uneventful, only later I finally found a couple of decent goniatites, and a small round intriguing fossil. One of the members also found a very nice orthoceras in the morning. At 12h we gathered for lunch and a quick review of the discoveries. Then we were surprised by heavy rainfall, it only last for 10 minutes, but more were clearly to come. In the following hour, we had several downpours an several participants started to give up and head back home. I stayed with a dozen participants and after a while we finally had dry weather again. Now we were looking for a layer that I discovered last year with small cephalopods. With a friend we managed to clear 1 m² of that layer, and it turned out great , together we found around 26 goniatites and a bunch of orthoceras and bactrites. Not all were well preserved, but some of them were really good specimens. Finally at 17h we called it a day ,and with the last participants we visited a local tavern for a drink and supper. Double goniatite As for the little round fossil, after some prepping, it turned out to be a crinoid calyx Cheers, Kevin
  24. It has been a while that I made a decent field trip. Past Sunday I left with 2 friends to a quarry in the Ardennes from Belgium. Last year we made a few visits to that place with great success and a fair number of late Devonian cephalopods were found. So hoping to add a few goniatites to our collections we left early in the morning. The weather conditions for the trip were terrible: it was raining and the wind was blowing very hard. Before we got to the quarry the rain stopped, but there was still a lot of wind. The rain had turned most of the flat parts of the quarry into a muddy swamp. But the heavy wind blew the last dark clouds away and we started our prospection in the slag heaps on top of the quarry. The first corals where collected, mostly hexagoniaria and a worn goniatite . I made my find of the day in the first 30 minutes in the quarry: In one of those slag heaps I found a large boulder with a large orthocone on it. The specimen was deformed during fossilization, but after clearing the specimen out it proved to be a complete orthoceras of 25cm in length. This was a monster compared to the most specimens I found there before. The next stop was a level lower in the ancient part of the quarry, here they were dumping the rocks that where not suited for production, but luckily for us, lots of fossils could be found in them. This was the most productive part of the day. Although they were hard to find, each of us found at least a couple of decent goniatites. The rest of the day we spent in the back of the quarry where lots of corals can be found and sometimes a nicely preserved goniatite. Multiple mineral veins are also present with large barite and calcite crystals. Sadly with the expansion of the quarry the part with the corals was cleared with bulldozers and fossil finds where rare at that location. Still I managed to find an exquisite goniatite specimen, a little damaged, but with very clear suture markings. My two friends searched through the mineral veins and found multiple good quality barite and calcite crystals. Meanwhile I prospected other parts and collected a little bag full of small corals and crinoid stems. (Back to the car with heavy Calcite and Barite cristals...) Usually we end our day at a local tavern for a drink, but this time I was too tired and I still had an hour drive to home. I’m already looking forward to my next field trip on 21/02 Then we will be prospecting early carboniferous deposits. Kevin
  25. New fieldtrip to the late and mid Devonian in the Ardennes from Belgium. This weekend I went with my friend Anthonie to a last minute field trip. The weather forecast were promising for that Sunday: gray but dry and decent temperatures so this was a possibility to make a last fieldtrip for this year. So Sunday morning I woke up early to leave for the fieldtrip… of course when I looked outside it was pouring. Still, hoping it could only get better I took the highway to Brussels, picked up my friend and we went to the direction of Marche en Famene for our first stop. It took us a one and a half hour drive in the rain to get there. Luckily the sky got a little less gray and the rain ended. We got to our first stop, a large construction site for a new industrial site. I went there before with my daughter with great success and I wanted to inspect the spot more closely. The huge construction pits exposed late Devonian schists (Frasnian), those deposits are well known to amateur collectors and can deliver a large quantity of spiriferid brachiopods, sometimes of very large dimensions. We spent almost 2 hours on the site, the bulldozers had done a great job clearing everything and we just had to pick up the brachiopods laying around everywhere. It was easy to fill up our bags and we only prospected a small part of the site. Apart from the huge amount of Spirifers, from which a few of them where around 3” we also found solitary corals, and a pair of gastropods. (probably Euomphalus sp.) We then took a quick lunch and headed to a new location a few miles further to a Quarry with mid. Devonian deposits (Givetian) This was the first time we prospected this site, so it took us a while before we could find a few decent fossils. The first ones we found were multiple large colonial corals and stromatolites, giving us a clue about this ancient reef and lagoon system. Most of those where too large to carry around, so we took a few pictures and we continued the prospection. In most parts of the quarry we found other large corals, but when we got to a scree we found multiple small solitary and colonial corals. We inspected this more closely an discovered lots of nice small fossils including a variety of very beautifully preserved brachiopods. After further prospection we went back to the car, making sure to pass by the first spot with the large corals. Where we each took a large specimen back to the car. We had still a little time on our hands and went to a 3rd location, an old quarry. When we got to this spot we were surprised to see that they started to fill up the location with debris. On the positive side the debris where mostly schists from a construction site. And again delivered a few nice spiriferid brachiopods, although very few in numbers. I think another group of collectors must have been screening those debris before us, a large amount of footprints where all around the place. We went to the back of the quarry to take a few extra pictures before heading back home. here I heard small pebbles falling from the cliff at the end of the quarry. We then saw quite a spectacular sight: a fox went down the cliff at an incredible speed, I thought he was stuck and would fell off, but halfway the cliff he went into a hole in the wall. Probably his den. We went closer to get a better sight but we made a new but gruesome discovery. A large dog lay dead at the bottom of the quarry. he probably fell of the cliff and it was not far of the den, so maybe this happened due to the dog chasing the fox. We took a picture of the collar, It had a cellphone number on it. We later contacted the owner to let him know what had happened to his dog. He was sad to hear the news, the dog was missing for two weeks after a hunting party, so this only confirmed our suspicions with the fox. After this incident we got back to the car and headed back home ( again raining during the whole trip) Although the day ended on a sad tone for the dog we did get a lot of great looking fossils. Il post updates of the finds after their first cleanup. Enjoy the pictures: Kevin 1st location: Late Devonian schists Looks like Santa came early this year: 2nd location: Mid Devonian reef deposits: 3rd location: note the piles of schists dumped in the quarry: Thanks to PaleoTony for the pictures.
