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

Found another interesting specimen on this Nodule from Smokejacks quarry, measuring under a 1.0mm approximately 0.3mm in length, was quite difficult to photograph. First impression due to it’s almost wing like features I would suggest possible insect. As the concretions of sideritic ironstone and fine grained calcareous sandstone have also yielded numerous insect remains including non-angiospermous plants (ferns and cycads, and a Sequoia-type cone). The quarry cuts through a section of the Wealden group, specifically the Weald Clay. The clay was deposited in a lake and floodplain environment during the Barremian stage of the Cretaceous period about 129-128 million years ago.
