Lyme Regis crustacean fossil- Which stratum would this originate from?
Paleoworld-101 posted a topic in Questions & Answers
This fossil crustacean was collected in England on the foreshore between Lyme Regis and Charmouth, amongst the algae-covered large boulders that are exposed at low tide. It looks to be in some kind of phosphatic nodule. The cream-colour of the matrix is quite unlike the dark Jurassic rocks that make this region famous. I was thinking it is unlikely to be from the Jurassic layers, and probably originates from the overlying Cretaceous sequences higher up in the cliffs? Both Gault Clay and Upper Greensand (Albian in age) unconformably sit above the Jurassic beds. Does anyone know which of these deposits are known to produce crustacean specimens with this type of preservation and lithology in the Lyme Regis area? Thanks for any input!

Found these 2 in the gault clay of Folkestone UK and after a while of looking online I'm stumped. they look like ammonite fragments but the preservation isn't great.

A fair amount of Cretaceous, Gault clay, Greensand Wealden fossils. They're not my field so I have no idea what they are. All are UK specimens and from Kent or Sussex. There aren't any reliable labels! I'm looking for vertebrates in exchange

Hi all, After reading the "Geologists' guide to The Isle of Wight" I popped out to Compton Bay the other evening. Due to big spring tides I only had access to the Gault Clay and Upper Greensand area available at the far western end of the bay. As you can see from Compton Chine, it was windy enough to blow the water upwards : (youtube link) After a while I managed a few bits and pieces to start my collection. Every single one of the appeared exactly in the right section of the book. This made identification somewhat easier. The book is a bit of a 'must have' for people like me, who are new to this. There were a few large ammonite 'negatives' in some of the Greensand rocks, but I'll need to get down the there over low tide to investigate further. Here's what I found from the short time I was there. Here's a closeup of the ammonite, it has a lot of rock to be removed, but I don't have to tools (yet). I'd thoroughly recommend getting this book, if you plan an Isle of Wight visit: Regards, Steve.

Hi, Some of you may have seen my post yesterday about unexpectedly stumbling across some ammonites here in the Lower Cretaceous sandstones (Lower Greensand) on the SE Isle Of Wight, on a beach I would never have thought to look. Last night I headed back down there with the intention of properly collecting and testing how abundant this new site was. I was not disappointed. I scrambled along the rocks from Bonchurch and got down there around 7pm, (just a 10 minute walk from my house) and began to systematically scan the beach. Within about an hour I'd picked up more than 50 phragmocones and fragments of ammonites, some of which were a decent size. Phragmocones are by far the most common find, although why this is I'm not sure, possibly due to environmental energy breaking up the ammonites? As far as I can tell the ammonites are parts of nodules which are originating from a hard, glauconite rich bed at the base of the cliff meaning they seem to be from the upper most parts of the Sandrock fm. Some however also seem to come from the Monk's Bay Sandstone fm. (Carstone fm.) which overlays the Sandrock. These were laid down in a shallow sub-tropical shelf sea during the Albian stage (100-113mya), other formations of the Lower Greensand are estuarine/mud flats showing a cycle of sea level rise before the final marine incursion laid down in the Gault (which is also present here on top of the Lower Greensand). As far as species, most of the fragments seem to be members of the Hoplitidae, I've identified one as being Hoplites maritimus, although I think I'll post some up in the ID section as my ammonite knowledge isn't that great. There seems to be much larger ammonites present at the site too, as at the base of the cliff some large moulds could be seen (although the ammonites themselves were gone). There is also an abundance of large pieces of fossilised driftwood, which would likely have originated from land to NE. Needless to say it was a very productive trip (unfortunately the seal didn't return), and it's definitely rekindled my interest in the cretaceous strata here on the island and the fantastic finds it has to offer (I might even start pursuing the dinosaurs again!). If the weather holds I'll head back again this evening to continue investigating the site and the strata, I've also attached images of the finds below (including the larger moulds). The entire haul from the trip, lots of phragmocones An example of the phragmocones Some larger sections of ammonite, although I'm not sure on their ID's
