  1. On the last few fieldtrips to the quarry in Southern Belgium where we look for goniatites we found quite a few plant remains in some of the anoxic marine deposits. A friend of mine thought that one of these remains could be Protocalamites sp. , but we find verry little info about that plant. Does anyone know when they first occurred? The layer where we found the remains were from the Late Devonian: Frasnian – Matagne formation ( Upper rhenana conodont Zone ) Any comparison pictures or papers on this subject are welcome.

    holiday goniatite hunt.

    During our holiday in the ardennes we made a compulsory stop at our favorite hunting spot for devonian cephalopods. There has been a lot of new activity in the quarry, but sadly not in the best deposits for fossils. They are also starting to fill the older spots with ground. But the usual exposures were still delivering some goniatites from time to time. And we dit get quite a good haul this time. There was one notabely well preserved Manticoceras sp. and as a bonus we had a rare nautiloid. I cleaned up a couple of the goniatites with chemical prep; the result was spectacul

    From the album: My collection in progress

    Cyrtospirifer verneuilli Murchinson 1840 Location: Barvaux-sur-Ourthe, Wallonia, Belgium Age: 382 - 372 Mya (Frasnian, Upper Devonian) Measurements: 6,6x3,5 cm Kingdom: Animalia Phylum: Brachiopoda Subphylum: Rhynconelliformea Class: Rhynconellata Order: Spiriferida Family: Cyrtospiriferidae

    Jaw section and teeth of sarcopterygian fish, possibly Laccognathus panderi. Lower Frasnian, Late Devonian, Lode Quarry, Latvia.
  5. It has been a while since I’ve posted some goniatites. The expansion of the quarry where I look for them is nearing to the end, and most of the good layers are gone. but sometimes we still find some neat specimens. this one was found a month ago. I used potassium hydroxide for the prepp of this one. The chemical reaction worked realy well on this specimen. Manticoceras sp. Late Devonian, Frasnian Belgium.
  6. We recently moved to a new house, so It has been quite a busy few weeks since we last made a field trip. So I hadn’t much time to post the recent finds. On our last fieldtrip to the Belgian Late Devonian I made an exceptional find that I still wanted to share: I found a large piece of bone sticking out of a nodule. After the preparation and a some research I ‘suspected that the piece was a ADL (anterior dorsal lateral) armor plate from a Dunkleosteus. I’ve sent the pictures to a friend Palaeontologist specialised in Palaeozoic fish who confirmed the ID. Dunkleosteus
  7. Hi everyone! Around 2 months ago on the 16th of october 2021 I went on a fossil hunting trip with the BVP to the stone quarry of Lompret in Belgium. https://www.paleontica.org/locations/fossil/654 The rocks in this quarry are Devonian in age and date back to the Frasnian (382.7 million years ago to 372.2 million years ago) with the finds mostly being from both the Neuville and Matagne Formations. According to Tom our excursion leader this quarry exists out of what used to be coral reefs and islands that formed around atolls. The fossils that you can find in this quar

    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

    Well preserved goniatite prep.

    Lately Natalie is surpassing me on finding cephalopods. It is not every day that we find a Crickites sp. In the field, let alone a well preserved specimen with the living chamber. So I went to work to prep her precious find: It was a very promising looking specimen and it lived up to the expectations. Crickites sp.

    Fossilized raindrops?

    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?

    Devonian fieldtrip with a view

    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.
  12. 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

    double goniatite fun

    It has been a while since I've found a decent sized goniatite on my favorite huntingspot, since the good deposits are no longer accesible. But recently I did find a specimen in a recent buldozer track. sadly the specimen has taken a hit from the vehicle moving over it. The extra bonus on the other hand was that there was a 2nd specimen right next to the 1st one. I've rarely seen 2 Manticoceras sp. from this size on the same matrix, so I was very happy with this one On top of that the preparation went realy smooth

    Pachyphyllum nevadense

    This is a small form of Pachyllum nevadense that has corallites with small corallas (the circular structures that have a high rim that stick above the surface). The coralla rim diameters range from 1.25 mm to 2.5 mm and average 1.5 mm to 1.75 mm. The corallites average 2.5 mm to 8 mm apart center to center with an average of 4 mm to 5 mm apart. They have an average of 20 septa. The measurements partly overlap with those described for the species by Stumm in 1948: coralla rim diameter of 2 mm to 4 mm; average of 3 mm; distance from corallites centers of 5 mm to 10 mm; 18 to 24 septa.

    Iowaphyllum nisbeti Oliver 1978

    This Late Devonian silicified coral was first found in the Superstition Mountains by Gladys Turner Nisbet who was a botanist from Cave Creek, Arizona. I found mine nearby. Wikipedia: Link Measurements given for whole colony. Coralites vary from 10 mm to 40 mm across. Average is 15 mm to 20 mm.

    What the...? What is this?

    This “fossil?” Confuses me. Is it even a fossil? The shape throws me off makes me think its artificial but i found it in the middle of nowhere on rocky river shore. Geological?

    Fish bone or sponge?

    Another driveway find. Is this a sponge of some kind or possibly and bone from dorsal fin? Kind of looks in the shape of the ulna i cant find any reference on what an isolated one looks like. Can bones be calcified like this? i have no idea.

    Double goniatite prep

    This weekend we finaly got out after those long months of lockdown. This time I am prepping a gephuroceratid that Natalie found. They are often found on top of the limestone banks, but this time she found one peeking out the center of the limestone bank. The position of the fossil didn’t make the prep any easier, since I had to grind away as much as possible of the matrix with a powertool without cutting in the fossil. Luckily I just missed a 2d goniatite hidden in the matrix with the grinder. After 4 to 5 hours of prepping with grinder, chisels, with air scribe and a
  21. Finally time to go back in the field after that long period of confinement . So this Saturday we went back to the Ardennes to prospect Frasnian ( Late Devonian ) deposits. Not a lot of finds, but it was good to be in the field again, and Natalie did find some nice quality fossils. Enjoy the pictures : A placoderm fragment: Bryozoa: not a fossil coral nodule with a few Tornoceras: same piece after a little work:

    Orthocone prep

    It has been a while since I've posted on the forum, so here is a prepwork from this weekend It is a late devonian orthocone, it was quite a hustle to get this out of the rock, it broke in 3 pieces during the extraction in the field. Only a part of the shell was exposed, so I took a whole lenght of matrix back hoping that it contained a whole specimen, and it did The prepwork went realy well, and even the tip of the orthocone was preserved. The 3 parts glued back together, showing only a glimps of the orthocone: clearing out the fossil:

    Devonian cephalopod prepwork

    I have acces to a more powerfull compressor since last week, so the past few days we have been quite bussy prepping lots of fossils. Those are some of my late devonian fossils I have prepped, this is my favorite one to start with, not only does it have 2 cinds of goniatites but I found it at adifferent location than the one I usualy prospect.

    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
  25. Saturday we went back to the south of Belgium to check out the quarry where I like to hunt for goniatites. The last 6 months there was litlle activity in the quarry and I was hoping that things had changed by now and the would have dug further, but alas there stil was no change. Still the bad weather and the storms of this winter cleaned out a lot of debris, we did find some nice fossils. At 1 pm we had to give up searching and ran back to the car due to heavy downpour and wind. Start of the day, gray and windy , but still dry: ptospecting the rubbl
