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.

I took another trip yesterday to the Kimmeridgian site in the Danube Valley and continued my dig in the divisum zone. This time I came up with, among other things, a Pseudhimalayites uhlandi ammonite with a diameter of 18cm. These things can get quite large, so I'm dealing with just the phragmocone here. As I've mentioned in other posts, this exposure is in the middle of a sponge reef, so a lot of activity was going on here at the time that this creature hit the dust, so to speak. It landed on a group of sponges and began to deteriorate and deform, revealing the insides of some of the septa, but not before a number of epizoans, such as tube worms, colonized it, some bits of sponge got stuck to it, and another little ammonite shell dropped onto it before it was finally buried and retained for posterity. The photos below can be enlarged to have a better look at the detritus. Thought it might interest you.

Last Thursday I posted a report about a recent dig in the Kimmeridgian here. It was successful enough that I decided today to return and continue with what I had begun. First I had to contend with some water again and then I spent a couple of hours removing more overburden to get at the layer and then started moving shale and concretionary blocks. I made some good finds again, including a very large Crussoliceras. Forgot to take in situ photos of the finds since I was too busy getting excited, with the exception of this very last one as it was starting to get dark. I did however think to take a photo of most of the finds a few minutes earlier. Looks like I've got some work ahead of me again

I visited the Kimmeridgian ditch again this week and just finished prepping the finds. I didn't do too badly this time, I'd say. Parataxioceras sp. & Ataxioceras hypselocylum on matrix. 16x12cm. Involuticeras involuta with a Pseudolimea sp. bivalve ø7cm. Laevaptychus obliquus with a small Glochiceras sp., an even smaller and pyritized Aspidoceras sp. and a sponge. 7x7cm. Two more Laevaptychus obliquus, parts of the jaw from Aspidoceras ammonites. Both are 5cm. long. Taramelliceras compsum. ø7cm. Aspidoceras sp. phragmocone with part of the living chamber. ø14cm.

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.

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.

Ichthyosaur paddle digit (Wimereux): hit or miss
pachy-pleuro-whatnot-odon posted a topic in Fossil ID
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?

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...

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?
