  1. Hi all! I was finally able to visit the Volga site thanks to a water level/ good weather window. The journey was mostly a success, I got a better understanding of the site, used new means of transportation and examined more of the shoreline. Among the finds were two dozens of marine reptile verts and bone fragments and LOTS of ammonites and other mollusks. Unfortunately the river level was not low enough, 1m higher than during my 1st trip, 0,5m lower than in the 2nd. But it was at least possible to walk the shore. There's still a lot more to do, but now I have a pretty clear idea how to maximize the hunt results for the next trip. The report will be picture-heavy and divided into several blocks I'll be adding in the next few days. Let's start with the scenery.

  6. Mystery bone from the Boulonnais

    Hi all, Back once more with a find from the Boulonnais. This time found between Boulogne-sur-Mer and Wimereux. The geology there is Kimmeridgian marine deposit, and the fossil presented here derives from a block of yellow sandstone with marine inclusions. It was embedded in an enclosure of soft, porous sand, which I hadn't quite expected and is the reason it's currently in the state it is in. I managed to find a rock with a pycnodont fish tooth and some similarly coloured (i.e. white) bone fragments in the area, in comparable yet harder sandstone. So my first impression was some kind of fish bone. However, I'm having a hard time figuring out what kind of fish bone, seeing as my piece is flat on one side and appears to have a bit of a twist (or may be a depression where another bone would have gone) on another. As such, the flat side made me think of a jaw bone, of a marine reptile in particular. Yet, the bone seems to extend away from it's flat side, which wouldn't quite fit what one would expect of a jaw bone. My third guess, based on the slight depression on one side of the bone and the rounded end at one of the short sides (which kind of reminds me of the epiphysis of a long bone), was some kind of long bone - lower arm or lower leg, where you'll typically find two bones lying closely together - but I'm not sure of this either. Moreover, this would be the feature of a terrestrial animal, not a marine one - with the exception of crocodiles (which lower extremity bones, however, are not closely spaced together, so wouldn't match my hypothesis). I realise the bone is fragmentary and not even in the best of states. But I hope enough has been preserved to determine something of it's origin, if even just in terms of marine vs. terrestrial, reptile vs. fish or mammal, etc. Dimensions: 86.5mm/3.40" long, 42.6mm/1.67" wide, and 23.5mm/0.92" tall Thanks in advance for your help! Don't hesitate to ask for additional details.
  7. It's become a regular habit for me to visit the site in the Kimmeridgian in the ditch at the side of the road at least once a month. For one thing, it's less than an hour's drive away and it's also relatively easy to work for an old codger like myself. No forging through the woods, clambering uphill and breaking hard rock. All I have to do is get out of the car and mosey a couple of hundred yards down the road and into the ditch. The marley limestone is easy to take apart, and as long as the hypselocylum zone is giving up its offerings, I'll be happy to keep on visiting it regularly. You just have to love the Upper Danube Valley, not only for the fossils, but also purely for it's majestic scenery. I thought to take my camera along today, so I was able to take some shots as I was working away. Spent about 4 hours there and I hit a good spot. Here's the first find after just about 20 minutes. Then they were popping out fairly regularly for the next few hours. Here are a couple of "discovery" and "breaking out" pairs of photos.
  8. Urchins from Charente

    Hi everybody, i found those pieces in A Kimmeridgian layer for the Cidaris and a Cenomanian layer for the other pieces and I'd like your opinion upon them. Kimmeridgian Cidaris : that's the fourth time I go in that place, I always found radioles but this time i come back with a piece of test. In the Cenomanian I found that urchin, I think this is a Leymariaster : This one is also an urchin according to me I think this is also the case for that piece but I'm not sure. @Coco, I did found urchins in Port des Barques, you mustn't despair, never. @caterpillar, what do you both think?
  9. Ichthyosaur paddle digit (Wimereux): hit or miss

    Hi all, Found this stone at Pointe aux Oies in Wimereux two days ago, amongst the pebbles collected next to a shelve down towards sea from the spot where I had found an ichthyosaur vertebra (on matrix) two days before this find. I picked it up because 1) the stone is unusually flat; 2) has exactly the right shape and thickness to it for an ophthalmosaurid ichthyosaur paddle bone (see picture below); 3) has certain ornamentation top and bottom; 4) seems to be of a different type of stone than I've generally come across in the area; and 5) has some weight to it. It vaguely reminds me of paddle bones found in the Oxford Clay at Peterborough. Yet, what makes me doubt, though, is that there is no clear radial ornamentation on either top or bottom of the piece, as would by typical for an ichthyosaur paddle bone. A friend of mine, more familiar with fossils from the region, suggested it could be a crocodile scute, as the ones found further up the coast, but this, to me, seems unlikely, as 1) the ornamentation on my find differs significantly from what's typical for crocodilians; 2) the underside is not flat as it would be for crocodile; and 3) the piece seem to thick for a scute. Size is about 4.4 x 3.4 x 1.4 cm (1.7 x 1.3 x 0.6 ") Brachypterygius extremus paddle from Ichthyosaurs: a day in the life... My piece reminds me of the radius. Now my question is: Is this just a rock - i.e. am I seeing things because I really want to - or is it an actual fossil? Is this an ichthyosaur paddle bone/phalange or something else?
  10. Oddly shaped bone in pebble from Cap Gris Nez

    Hi all, Found this pebble on the beach close to Audresselles (Cap Gris Nez area, Boulonnais) amidst the heavy rain and wind yesterday. Initially, I thought it was just a piece of odd-looking fossilised plant-material, with a faint thought in the back of my mind that may be it could be a fish skull. When I checked it this morning, I was able to confirm the piece is smooth on the outside, and seems to have what appears to be bone fibres on the inside. In other words, I'm convinced now that it actually is bone, though still have no idea what kind...

  18. Late Jurassic finds

    I spent another day at the Kimmeridgian site in the Upper Danube Valley near Beuron the other day. I had taken my camera along in order to take some shots, but I ended up making so many good finds that I forgot to get it out. Sorry bout that. One great thing about this location is that the finds are easy and quick to prep, so at least I can show you some of the finds. Aspidoceras sp. Ataxioceras (Parataxioceras) lothari Ataxioceras (Parataxioceras) planulatum Taramelliceras (Metahaploceras) nodosiusculum and Glochiceras sp. Ardescia perayense Ataxioceras (Parataxioceras) sp.

  20. Plesiosaur?

    Hi all! What do you think of this vertebra? It was found long ago, comes probably from marine Kimmeridgian-Tithonian outcrops in the Volga basin, Russia. Doesn't look exactly like plesiosaur, but what else?
  21. Lucina concinna?

    Hi guys the info I know is on the label. However, I happen to know that Lucina concinna (deshayes 1857?) isn’t valid, so I looked up the replacement name which is Rugalucina cracentis but it looks nothing like it. I think the label is wrong. Any help would be great, thanks. Also calling our resident bivalve specialist @Max-fossils
  22. I spent the afternoon today exploring the ditches in the Upper Danube Valley and found something in all 3 of them. Spent most of my time at the regular ditch by the side of the road in the end where I've been slowly excavating the Kimmeridgian hypselocylum zone every couple of months or so for the last few years. I took a couple of photos of the work in progress and also one of my finds. I'll post them here again once they're prepped.

  25. A new fossil hunt on the French coast this weekend. The winter storms from the past week battered the coastline and this resulted of course in a few really nice finds. This time we weren’t prospecting alone, but two friends who recently started to collect fossils tagged along . The Saturday morning we prospected the late Jurassic beaches, we started with a slow start, but we finally did find 3 really nice echinoids, and a big ( heavy ) ammonite. At noon we went to the 2nd spot with late cretaceous chalk ( Cenomanian), here the storms really did their work, the recent scree piles were completely washed out and loos fossiliferous boulders were scattered all around. I did found some quite nice ammonites ( Acanthoceras rhotomagense and Cunningtoniceras inerme ), but Natalie hit the jackpot with 2 terrific finds. First up she found a huge and complete nautilus ( Cymatoceras elegans ) only slightly weathered on the side from peeking out of the boulder. A little bit further she found a big turillites ( Hypoturillites tuberculatus) from 25cm, the best part was that it came out in one piece, those heteromorphs usually break in fragments if you try to remove them. On Saturday we went to some Kimmeridgian exposures, but the storm on that day made it really difficult to search and we had to go back to the car’s after a couple of hours due to the terrible weather. But we did find quite a few Aspidoceras sp. ammonites. the saturday morning: saturday afternoon: The stunning Cymatoceras the turillites: The haul from this weekend:
