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.

GSAILL raison d' etre for this post : -classic locality -an in-depth analysis -I might be wrong,but for those who collect at/near/in this area,there's a lot of useful information in this thesis VERY NICE WHEELER DIAGRAM

Hello everyone, I am working on my dissertation (finishing bachelor degree) focused on jurassic (oxfordian) fossils from Brno Hády quarry (central Europe, Czech republic) and I need help with shark teeth identification. There are 2 photos from my friend attached - he collected the longest shark tooth I ever saw from this site and an interesting "double tooth", which may belong to Hexanchiformes perhaps ? I have collected about 40 shark teeth, which vary in lenght (1-18 mm), but overall seem pretty much same to me. Some of the teeth are broken and eroded, but about 27 shark teeth are, I would say, good. I have made a Shark teeth album on my flickr account recently and would appreciate if you could take a look at the photos and tell me your opinions. Could all of these belong to Sphenodus sp. ? Two shark teeth from Brno Hády site were described in 1936 by Oppenheimer - Sphenodus longidens. Since then, nobody posted a single work about the teeth found there, even though they are way more common there today then in 1930´s. I am going to collect more samples, borrow samples from my friends and friends of my friends and compare them. Then, I am going to take some better photos of them all, describe the anatomy and see, what I can do (hopefuly I will come with some conclusions). I would like to make a good job even though that I am not going to be a paleontologist. And before all of this I would like to ask you about your opinions. (The problem is, that there is nobody in Czech republic who would currently specialize in jurassic Selachinomorpha - and I am not going to be a specialist myself, as some people would like me to. I am not going for master degree and would not like to spend too much time with sharks, because there are also BIvalvia, Brachiopoda, Cephalopoda, Echinodermata and micro-fossils I would like to process. I am not going to be a paleontologist, since I have a job in local observatory and I am perfectly happy about it. I am not asking anyone to do my job. I am just curious if there is someone with experience in shark teeth identification, who could tell me his/her opinions.)

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! This is where I will be posting the best of my Talbragar Fish Beds collection over time. The site is near Gulgong, NSW Australia. They are from the late Jurassic. 1. Cavenderichthys talbragarensis, named after and endemic to the site (so far). This is probably my best specimen from the site, it is complete, large, and white. Continued...

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.

Juvenile Allothrissops salmoneus. There are two Allothrissops species: A. salmoneus from the Solnhofen lithgraphic limestones in Bavaria and A. mesogaster from the slightly older deposits in Nusplingen, Baden-Württemberg. The small dorsal fin is located behind the anal fin.

Yes, I have had a short holiday near Ravenscar. Here is another item. I'm hoping that someone can tell what I have here. Its from Ravenscar, (Robin Hoods Bay end) North Yorkshires Jurassic coast. The area yields ammonites, belemnites and marine bivalves.

This one must be fossil material. Picked up at Ravenscar, North Yorkshire Coast, Jurassic, Marine deposits. I don't know what it is.
-
Can anyone help me with this one? Its from the beach at Ravenscar, North Yorkshire coast, The area produces ammonites, belemnites and lots of other marine invertibrates. I am guessing at some sort of fan worm.

This is an Ammonite my wife picked up on the beach halfway between Charmouth and Seatown. We know that its an ammonite and Jurassic, but can anyone tell me more about it please?

Hi, found this concretion on Yorkshire coast, looks like can see head with pinchers with various other body parts, what do you guys think ? Thanks.

this summer vacation i spend a day fossil hunting at lyme regis i found some ammonites and bellemnites but also 2 big pieces of rock and i'm going to prepare them for a school project the rock formation was blue lias can i have any advice for cleaning the fossils?

I found this at Ravenscar, North Yorkshire. The area is Jurassic coastline with Ammonites, Belemnites and Marine Bivalves being common. There is also a lot of fossil wood in places. To my untrained eye it looks like a Therapod footprint but would welcome any more informed opinion.

I have been told this is the vertebra of a ichthyosaur. Can someone confirm this and maybe tell me where on the spine it was located? Is it possible to determine what species it was more specifically? Found in southern England.

Hi, out hunting yesterday and found this beauty in a chunk of shale, also found a small one at a different location, seems to be a very nice specimen, do you think I should leave the layer of shale on it or gently use the scribe to remove it ? I'm thinking remove as you wouldn't be able to appreciate it fully until you can see detail, thanks.

From a Callovian site in southern Poland I collected a lot od thick-walled tubes. Sometimes they seem to be a part of something bigger, but I mainly search small rocks on heaps so I don't have a more complete picture of the fossil. Associated are various brachiopods, bivalves (including oysters and Ctenostreon), serpulids, ammonites, belemnites and various different fauna. I think these are clearly not belemnites. I don't think these are crinoids. I consider bivalve fragments (e.g. spines of Ctenostreon) or some huge serpulids. Any ideas? Specimen No. 1: Specimen No. 2:
