With pleasure I want to show you my collection of fossils - it's a work in progress. My first piece is this Lycoptera davidi from Western Liaoning, my brother's gift for my birthday. The plate is 13 centimeters long, the fish 8 centimeters long.

Hi everyone! I have my eye on a really nice tooth from the Jurassic of Niger but before I get it I figured I'd ask for an outside opinion on it's ID. The seller says it's a Sauropod from the Irhazer formation of Niger and measures 2 inches long and .9 inches wide. Is he correct? Can it be narrowed down any further than that? Any insight would be greatly appreciated as always!

Hi Everyone! I've been looking around at some potential Allosaurus teeth I'd like to buy but before I do I'd like to make sure that's actually what they are and learn how to id them, as I'm assuming the Jurassic fossil market is as rife with misidentification as the Cretaceous one. Here's one I'm curious about, very clearly a Theropod tooth. Apparently found in the Morrison Formation of Washakie County, Wyoming and measures 1.08 Inches in a straight line measurement. So what do you all think? Is it Allosaurus? How do you know? Is it even possible to pin a Morrison tooth on Allosaurus or is there some other obscure genus with nearly identical teeth in that formation I don't know about like a Daspletosaurus/Gorgosaurus "Tyrannosaur indet." situation? Any insight on this would be greatly appreciated.

A few highlights from fossil hunting in the Amberg-Sulzbach county (Bavaria, Germany) in June 2022. There's small abandoned limestone quarries all over the place, picked a couple random ones and found these guys and dozens of more fragmentary bits.

I went to the museum today in Lourinha town and saw some of the amazing finds that’s have come out of this formation! Can anyone recommend the best beaches to go to to fossil hunt? Anything specific I should be looking out for? Basically any advice would be amazing! Thanks

New longirostrine pliosaur described from the Oxford Clay
pachy-pleuro-whatnot-odon posted a topic in Fossil News
Hi all, Just came across the exciting news that a new pliosaur genus and species has been described from the Callovian stage of the Oxford Clay near Yarnton in Oxfordshire. Dubbed Eardasaurus powelli (Powel's Yarnton lizard), it's a longirostrine thalassophonean pliosaur that is slightly more derived than Peloneustes philarchus (with which it shares numerous anatomical features) and forms a sister taxon to "Pliosaurus", Simolestes, Liopleurodon, Pliosaurus and brachaucheninae. A feature of particular interest in the dentition of this new species is the presence of connecting carina-like apicobasal ridges on some of its teeth. The article describing Eardasaurus powelli can be found here. -
I've been living in Chinese Camp, California for five years. I wouldn't have moved here except that I took my wife and two children looking for ammonite fossils. We found none that day, but we ended seeing an old country store for sale (only business in the abandoned town) and eventually bought it and live on the property. The fossils around here are all late Jurassic, but because of the forces that created the Sierra Nevada mountains, the fossils are very rare and in poor shape. Finding a whole ammonite, no matter small is a cause for great celebration, but this doesn't dampen my enjoyment at all. For several years we found some ammonites and a few Buccia (Jurassic brachiopod) but on rare occasions we found something long and tapered. I founds parts of these and they were segmented so I suspected belemnites. They are never (never ever) found alongside (in the same layers) ammonites, but they are in the same general formation (Mariposa Formation). Here are the fist ones I found, when I wasn't too sure what they were:

sometimes the best way to prepare Solnhofen-Fossils is to do it under blue light. This works perfect with nearly all crustaceans, vertebrate-fossils and some more. This one is fresh from the prep and needs finshing, huge Aeger spinipes (around 18 cm) from Eichstaett© fossils worldwide

Jurassic, Callovian, Oxford Clay, Peterborough Member This has enamel, and is the colour I associate with fish remains. Enamel made me think dentition or scale of some kind, but I'm puzzled by the shape. It has a couple of prominent tubercles, which made me think teeth or scale. Any pointers would be greatly appreciated.

I wasn't sure where to put this, but it's in the news so I went for here. Beautiful street art of the Rutland Icthyosaur. https://www-bbc-co-uk.cdn.ampproject.org/v/s/www.bbc.co.uk/news/uk-england-leicestershire-61436489.amp?amp_js_v=a6&_gsa=1&usqp=mq331AQIKAGwASCAAgM%3D#aoh=16528085406238&csi=0&referrer=https%3A%2F%2Fwww.google.com&_tf=From %1%24s

Jurassic, Callovian, Oxford Clay, near Yaxley, Cambridgeshire. The first fossil I picked up thinking it was a new echinoid spine, but under the microscope its structure looks quite different to the others I've found, and I'm wondering if it might be part of a fish spine. Those are my two best candidates for this. I would appreciate any opinions or suggestions. The second I think is the mould of a belemnite phragmocone, with some of the aragonite still attached. Every second bar on the scale is a mm.
