Unidentified Early Creataceous (Wealden) archosaur jaw bone with tooth
pachy-pleuro-whatnot-odon posted a topic in Fossil ID
I recently purchased an odd little archosaur jaw from the Wealden at Bexhill-on-Sea in East Sussex, UK. It's 14.88mm in length and 4.03mm tall, with a single remaining tooth of approximately 1mm in height. The seller told me he thought it would be Aigialosaurus, something I thought odd due to that genus only being known from Hvar in Croatia, and being much younger (Cenomanian) than this specimen (Valanginian). However, it turns out that a jaw was found at this locality at some point that has since been moved to the Bexhill Museum and was identified as Aigialosaurus (though, based on what, I don't know): While I'm working on figuring out whether the jaw in the other thread can indeed by attributed to an early mosasauroid (Aigialosaurus?), I wanted to ask people in this thread what they make of my particular section of jaw. Ventral Terminus (end of jaw) 1 Terminus (end of jaw) 2 Observe the tooth attachment with raised sockets, not unlike in mosasauroids. Details of tooth attachment. Here are the photograph of the jaw from Bexhill that was identified as Aigialosaurus again, for ease of reference (source): So, what do you guys think? Reptile or fish? Crocodile, lizard? Do you think my jaw compares well to the one identified as British Aigialosaurus? @caterpillar @Praefectus @ThePhysicist- 4 replies

Hi all, I was recently told about supposed Aigialosaurus/aigialosaurid (mosasaurus) material from the Wealden at Bexhill-on-Sea in East Sussex, and was wondering whether anybody knows anything more about this. Because, as far as I'm aware (Wikipedia), Aigialosaurus is described from Hvar in Croatia and, moreover, temporarily restricted to the Cenomanian, whereas these remains, stemming from the Wealden, would be Early Cretaceous in age (Berriasian through Aptian) - most likely Valanginian, as they were recovered from Bexhill-on-Sea. (Image source) I must say these remains do look rather mosasauroid, although I've been unsuccessful in finding further information on the specimen, which is supposed to be housed in the Bexhill Museum. The person who first told me about them remembers having seen a newspaper article, believes the British Natural History Museum was involved with the specimen back then, and had heard about a paper being written about it. That's about all I have to go on for now. So my questions right now are: does anyone have more information on this specimen; know of the publication; and what do people here generally make of this piece: is it mosasauroid, or could it be something else? @paulgdls @DE&i @Praefectus @caterpillar @The Amateur Paleontologist @Kosmoceras @ThePhysicist @Welsh Wizard @DanJeavs

Hi everybody. I stumbled upon those photos on another forum and i wondered about what are they, and about how and "who" made those alignaments of aptychi. They've been found in Valanginian marls, Saynoceras verrucosum zone. Concerning what and how, the authors of that article Double alignments of ammonoid aptychi from the Lower Cretaceous of Southeast France proposed several hypothesis : a possible bottom current ; regurgitalites of an ammonoid eater ; stomachal residues ; cololites. But their best hypothesis is cylindrical coprolites that separated in two parts just after the animal defecated or being close to the sea bottom or in relation to the anatomy of the anus or the cloaca. As to who, the candidates could be teleost fishes, plesiosaurs, ichthyosaurs, marine turtles, crocodiles. I'm very curious about those alignments of aptychi and wondered if one of you has seen something similar to this or could have an idea about the animal that produced them ? Thank you for your participation. Cheers, Sophie.

Brevistoris? 4 another polyacrodus? 5.cant remember the names of these fish teeth 6.another one I can’t remember the name of 7. a very large hybontid a bit fragmentary again

Mystery find in Bexhill fossil matrix (Weald Clay, UK), might this be fossilized skin?
ziggycardon posted a topic in Fossil ID
Hi everyone, I need some help identifying something I found yesterday when I went through my newly acquired fossil matrix. Some information on the matrix, it came from the Hastings Bone beds, Weald Clay, Wealden of Bexhill, Wealden Supergroup, Bexhill, Sussex, UK (Cretaceous, Valanginian, 135 million years old) To me when I found it, it looked like skin, not like the crocodile scutes I am familiar with , but really more like skin. But since I am not really an expert on the matter is doesn't really matter what I think it might look like. I do know dinosaur fossils are common there and I do believe skin has been found on that location before (at least footprints with scale impressions) Does anyone have a clue on what it might be? Skin (reptillian, dinosaurian, pterosaur, shark, fish)? Skull plate of a fish? a croc scute? a mouthpart of a fish? Something entirely else? Thank you in advance, and I am very eager to hear what you guys think about it, no matter the outcome, I am very excited to find out what it is. -
