Out hunting this morning, opened up a slab of shale and this was inside, looks like a lobsters tail to me but could be anything in this game, found on Yorkshire coast, thanks.

When our Plan A was killed we had to go to Plan B. Plan A was to visit a couple of old mines and sample the mine dumps for pyrite crystals and to try my hand at gold panning some of the tailings a little. This couldn't happen as there was some sort of bike race going up and down the canyon the mines were at the top of. Not wanting to waste the drive over there, we decided to visit the nearby limestone outcrops and viola! Pentacrinus crinoids! More pics

Hi all, I recently found this on a trip to the Jurassic Coast at Dorset and have been intrigued by this find, i'm not an expert on fossil identification and was wondering if there was anything significant about this fossil. it strikes me as being either fossilised wood or an infilled burrow of some kind, however the shine, shape and downward strikes are leaving me somewhat puzzled. i would be grateful for all your potential ideas as to what this could be.

Hi all, Anyone know what species/genus this bivalve steinkern is? It's from Rivière-sur-Tarn, a location in France that yields fossils from the Toarcian stage of the early Jurassic (approx 180 mya). Best regards, Max

Why Do a lot of Jurassic Bone Frags Seem Indeterminate?
Kurufossils posted a topic in Questions & Answers
Since getting into fossils something has been bugging me alot about material from the Jurassic and especially material from such places as colorado, utah, etc. Alot of bone material I see online for sale, mostly fragments in various sizes are usually unlabeled and generalized as being from any dinosaur from the Jurrasic. I wonder if there is at least a way to differentiate at least herbivore bone from theropod bone (like allosaurus from camarsaurus)? Is it similar to the method used for cretaceous bone of the honey comb pattern or not? I'm curious why it seems harder to identify Jurassic bone piece, I'd appreciate any input or discussion, thank you. For example would the first two pictures be considered theropod and the last herbivore?.thumb.jpg.c1c7f9d92a8cb1c0fb35cdc900f27954.jpg)

I purchased this bone fragment at a fossil show. It's from the Morrison formation of Utah. I suspect it's theropod, most likely Allosaurus because of its hollow nature but I just wanted to get other opinions on it. Thanks everyone!

Found 21st Aug 2017 on Kimmeridge beach Dorset UK so late jurassic era. The centre line is slightly raised, the edges clean cut.

A new Jurassic theropod from China documents a transitional step in the macrostructure of feathers
haventbaptized posted a topic in Fossil News
Genuine fossils with exquisitely preserved plumage from the Late Jurassic and Early Cretaceous of north-eastern China have recently revealed that bird-like theropod dinosaurs had long pennaceous feathers along their hindlimbs and may have used their four wings to glide or fly. Thus, it has been postulated that early bird flight might initially have involved four wings.

I went to Yaxley today, and after processing most of my finds I'm left with a few puzzles. I recently found an echinoid spine, and was wondering whether the first one below is part of an echinoid test, The second was picked up as a belemnite, but the cross section looks wrong, and I've seen echinoid spines in museums of a similar shape. The third bobbly one I have no clue, and would be grateful for any suggestions. I've called it Mr Bobbly. Finds are from Yaxley, UK, Jurassic, Lower Oxford Clay, Callovian. ETA: the order of the photos changed as I posted, the first fossil is the round black one in the images, the second is the very pale belemnite-like one, including cross sections, and the third is the long bobbly one.

Hello again, This is from Ravenscar, (the Robin Hoods bay end). It came out of a lighter sandstone and I am hoping that someone will tell me its a coprolite. Although given my recent record of posting non-fossils its possibly just geology.

Scientists Find Gliding, Proto-Mammalian Jurassic-Era Fossils
Doctor Mud posted a topic in Fossil News
Here's a link to an interesting article on these amazing finds: I wonder if @jpc might be able to provide us with any personal insights on these discoveries? I think he is keen on early mammal fossils? https://www.inverse.com/article/35301-gliding-prehistoric-mammals-jurassic-fossil And images of the fossils: This fossil of Maiopatagium furculiferum shows evidence of wing-like membranes that paleontologists suspect helped it glide like modern-day flying squirrels. In this fossilized Vilevolodon diplomylos, the arrows indicate the imprint of the gliding animal's wing-like membrane.

Hello please can I have people's opinions of if this is a bone or a rock. It was found on the Jurassic coast in the UK

Hi I found this on the beach in Dorset UK. The sediments are maritime Jurassic. I think it is a bone but I've no idea what from or even if it is a bone at all. It has the surface texture of bone and is hollow through as you can see. Any help would be greatly appreciated. Thanks, Jo

This is from Robin Hoods Bay, Yorkshires Jurassic coast. I have no idea what I am looking at, but found it sufficiently interesting yo pick up. Any ideas?

Hi, opened this on Whitby coast, I'm thinking possible Ichthyosaur femur, what you guys think ? Thanks.
