From the album: FreeRuin's Finds
Either a small footprint or a partial one I believe it to be a Grallator due to its shape and size. Picked it up while hiking. Hartford Basin Portland Formation Massachusetts -

A mud crack preserved in the shale, I determined it not to be an ichnofossil due to more that turned up in the rock. Hartford Basin Portland Formation Massachusetts -
Hello, I am Richard from Chinese Camp CA. I live atop the Mariposa Formation which is late Jurassic. I try to go fossil hunting every weekend. The quality of fossils is not great, but I regularly find ammonites and buchia, and less often belemnites (and a few oddities I haven't identified). I was born in England and found an ammonite when 5 or 6. I've loved fossils since them (I'm 50) and take my son out hunting for them regularly. I spent 11 year in the US Navy on submarines, and the last 20 at a research lab. To all of you: Best of luck collecting, learning, and enjoying fossils! Richard

Jurrasic shale cylinders with a square hole down the center (??)
Richard Beale posted a topic in Fossil ID
I live in the Western Sierra Nevada region of California near (on) the Mariposa Formation. I find ammonites, belemnites and buchia (common Jurassic bivalve). I also find cigar shaped somethings (fossils?) in the same strata. They come in many sizes with the larges about the diameter of a US quarter (as are the ones in the picture), down to only a few mm diameter, and their length is one to six cm. The always have a very square hole running down the length of the center. The first time I found one I thought there had been a pyrite crystal that had been chemically dissolved from the center of a concretion, but the wholes are only square in cross section, they pretty much always go the length of the cigar shape. These come from Oxfordian Jurassic shale with the other common fossils listed above. I'll be going back to the main site to collect more Tuesday and hop to post more. Any identification help would be appreciated! Richard

Hello everyone I have here a specimen and can’t figure out if it’s just a plain ol’rock but I think it might not be a rock at all. This specimen weighs almost 5lbs it’s original location was found in Carrizo Springs Texas at a drilling rig location. Some helpful info and opinions about what this specimen could be would really be great -Thanks y’all!

Again, a piece from my fossil buying trip locally! All I know from the store is Germany, Jurrasic, and Ammonite. Any ideas as to a genus? I love this one!

Hi all, Found this big ammonite at a landslide in the cliffs at Wimereux, France. It's from the Jurassic. Do you guys think it is worth prepping? If so, what tools/techniques should I use, and what should I expect as a result? And do you have any other tips for an amateur preparator like me? Thanks in advance, Max

Hi all, Wondering what bivalve species this is. Found at Cap-Gris-Nez, France. From the Jurassic. Looks like it may be a Pholadomya species to me? Not sure... Thanks in advance, Max

Hi all, Found this at the beach in Cap-Gris-Nez, France. The fossils there are usually Jurassic, but I'm not sure if this one is from the same layers. Looks like it might be a sponge to me? Maybe not. Looking forward to your opinions, Max

From the album: Vertebrates
Pholidophorus sp. Upper Jurassic Tithonian Painten Germany -
The Caturidae are represented in the Solnhofen Formation by at least four species: Caturus furcatus Agassiz 1834, Caturus giganteus Wagner, 1851, Caturus pachyurus Agassiz, 1833 (all from Solnhofen) and Caturus bellicianus Thiollière 1852 from Solnhofen, Germany and Cerin, France. The last two species were transferred to the revived sister genus Amblysemius (now Amblysemius pachyurus and Amblysemius bellicianus). C. furcatus was clearly a predator as evidenced by its mouth full of sharp teeth. It was a notable fast swimmer possessing an elongated, somewhat thickset body with slender head. Together with its only sister genus Amblysemius, Caturus was a member of the extinct Halecomorpha family Caturidae. It appears that the halecomorph Liodesmus, known from Solnhofen only, is related to the Caturids, rather than the Amiiforms, as has been usually surmised. Caturus possessed ganoid scales that are more cycloid in nature and as a member of the holosteans a bony skeleton with a partially ossified vertebral column. The head is short an equipped with powerfully toothed jaws. The dorsal fin is pointed and attached just posterior to the body's midpoint. anal fin is attached somewhat more to the rear. The caudal fin is large and deeply divided. Juvenile species.

Fossil Hunting in the Pas-de-Calais So last week was a lot of fun for me. Saturday afternoon we left home to go to northern France, the Pas-de-Calais. We first stopped in Belgium to visit some family, so we only arrived at our B&B near Wissant in the late Sunday afternoon. Our main goal was to go to that region in order to do, obviously, fossil-hunting! And that is what we did. I gotta say that I was (pleasantly) surprised with how things ended up! Read on to see what we found... Day 1: Wissant The evening of our arrival we were walking in the small city of Wissant, which lies in between the two famous Caps: Cap-Blanc-Nez (to the north) and Cap-Gris-Nez (to the south). Therefore it is a popular place for visitors to stay during the holidays, as it is ideally placed in between the two main touristic sites of the area. We had a really nice Bed & Breakfast on the outskirts of the city, so that was good too. Anyways, so we were walking the city to try and find a restaurant for the evening. At some point, I come across this small area where there is very dry mud/sand-like sediment, in the middle of the city. I look inside and there are lots of bones and jaws from different critters! Also a few shells. Although everything was in matrix, I still suspect that the things are modern (in the sense of 'non-fossil'. I'd say it still is a few hundreds of years old.), mainly because the bones are from sheep, cow and the shells are from edible species. So probably remnants of some primitive food-left-overs junk pile or something. There were also deer bones too (roe?), not as sure as to how that got there. Anyways, even though the bones are probably modern, still cool finds IMO! Total haul

Hi all, Earlier in spring, i had to organise a field trip to "les Vaches Noires" cliffs in Normandy for my association. I decided i should do a trip earlier solo (in february) to see how it had evolved since my last visit. It happened to be kinda useless since with thaw and heavy rains it had evolved so much between my 2 visits... Epoches covered are mainly jurassic (caloivan and oxfordian) but also cretaceous (cenomanian). For pictures of the site itself, you can have a peek to Nala's recent report here : On first visit, i didnt find much that worth mentionning beside a bunch of oxfordian echinoids : nucleolites scutatus and a big ammonites (a bit worn out but still) from oxfordian also : Perisphinctes sp The club trip happened to be much rewarding : In the callovian clay from the beach, i found this nice pyritized Quenstedoceras lamberti On the lower part of the "cliff", i managed to find this one : Quenstedtoceras messiaeni ? and also that oxfordian big gastropod : bourguetia sp Also put my hand on a few complete echinoid spines Paracidaris florigemma spines : On the close up of the bigger one you can see the quality of the preservation : As usual, more samples can be found on my TFF gallery (i also added 2 specimens from 2017 i hadn't shot yet) or on my flickr :

This was possibly the most impressive museum I’ve ever been to. I thought I would only be there 15 minutes tops...until you find all of the specimens that are waiting for you inside. 2 hours fly by in a blink of an eye...awesome experience.

Loved my trip to Portugal. I’ve never been to a place so geologically rich. I recommend all dinosaur lovers to make a trip there! Here are some pictures from my trip to the Museum in Lourihna/Dinosaur Park. If anyone has any questions about the pics or trip, ask away.

Does anyone know if toys/models of Steneosaurus (the slender-bodied longirostral Jurassic teleosaurid crocodyliform often found in Europe and the UK) exist? I'd like to get one if I can.

I put this before on the FB page but like to try here as well. This bone was found in Jurassic sediments in the Boulonnais area in the North of France. The sediments are marine but the sea was not far from the beach and sometimes terrestrial animals (dinosaurs) can be found. I think it will be difficult to say something about this bone. But it looks so fragile, hollow and almost birdlike (radius/ ulna??). Or am I seeing too much.....? Hope you can help me.

This is my most complete fish, and I found it last year. I went fossiling yesterday and found more fish bits, so hopefully it's a good layer of clay for fish. I thought understanding this one might help me with the individual pieces. More experienced people than me pointed out it's probably a skull, and there are vertebrae at one end (right hand side of first image). But I've been looking at fish skulls and I'm still confused. It looks like a snout at one end, which seems wrong. Is this distorted? I thought it might be Aspidorhynchus as that had a long rostrum, but I think it's more likely to be a leptolepis as they are more common. It could just be I dont understand the skull. Any pointers would be appreciated. Jurassic, from the Oxford Clay, Peterborough formation.

Can anyone help with a more specific id on these? The larger two are from Burton Bradstock and I assume the one on the left is a bivalve and the one on the right a sea urchin. The smaller piece in the middle is from Charmouth and another sea urchin. Both locations are jurassic and (obviously) marine.
