Hi everyone! Archaeologist here, looking for help with an Ammonite ID 😄 My dad and I found these two Ammonites near Sherborne in Dorset, UK. If anyone is able to tell me the species/age, I would be so grateful!

hi i found this today in northumberland in carboniferous rock. could this be a trilobite?

Hi all, While I'm aware that current Cretaceous exposures in Britain are largely restricted to the south and east coasts of the islands (see geological map below; source), significant marine deposition is said to have taken place across much of Great Britain from the Aptian onward (source). As such - and especially considering the richness of the record of the marine ecosystem during the Jurassic- one would expect an abundance of marine reptile remains to be known from British Late Cretaceous sediments as well, the epitome of which, of course, would be the mosasaurs. However, whereas finds of remains of ichthyosaurs and pliosaurs have been reported (see, for instance, Fischer et al. 2014 or Madzia 2016) - albeit from somewhat older strata than from which one might expect mosasaur remains to show up - very little information actually seems to be available as concerns this highly diverse group of marine squamates. When browsing the literature, for example, I've only found limited references to mosasaurs in Britain, most notably in Benton and Spencer's (1995) "Fossil Reptiles of Great Britain", in which the authors (p. 221) observe that Some further mentions of mosasaurs are made in this work on pages 264-265, which include lists of marine reptile finds at various locations across the country, as well as page 270, which describes St. James's Pit in Norwich, Norfolk, purportedly "Britain's best mosasaur locality" (ibid.). The pages have been reproduced below for ease of reference: Some material is also illustrated and described by Milner in "Fossils of the Chalk, second edition" (Smith and Batten, eds., 2002), but again minimally so: Plate 64 3) Leiodon anceps, Campanian, Norwich, Norfolk; 4) Clidastes sp., ?Upper Turonian, Dorking, Surrey; 5, plioplatecarpinae incertae sedis, Upper Chalk, Sussex Plate 65 1) Clidastes sp., Upper Chalk, Sussex; 5) cf. Tylosaurus, Santonian, Forness Point, east of Margate, Kent Outside of that, over the past couple of years I've only bumped into some loose specimens here and there being offered at auction sites, such as the below batch of alleged mosasaur teeth from Worcestershire, purportedly once part of the prominent Gregory, Bottley and Lloyd collection (at the resolution provided and in their state of preservation it's hard to make out whether they are indeed mosasaurian, however); or the mosasaur lumbar vertebra of unknown origin. It was actually these specimens that first attracted my attention to the existence of British mosasaurs, since so little has been reported on them elsewhere: an internet search doesn't result in anything fruitful, for example, nor have I come across any mosasaur material listed in museum collections. I would therefore be very interested in hearing what you all make of the above specimens, as well as the apparent paucity of British mosasaur material either in museums or published literature. Is this just the outcome of a collection/research bias, lack of suitable accessible exposures, or could there be another reason... @Praefectus @JohnJ @caterpillar @Welsh Wizard @paulgdls @DE&i and others

Hey! I have kind of an odd question. I am purchasing a fossil for a friend as a birthday gift -- between a tip of a mammoth tusk, or a section of mosasaur jaw with teeth. What makes this unique, however, is that we are traveling to the British Virgin Islands (from the United States) for said birthday and I would like to be able to gift the fossil on the birthday instead of waiting until she returns home as we live in different states and I would only be able to ship it to her house and not be there. I am concerned, however, about bringing the fossils with me on the trip as I have heard nightmares about customs causing long hold ups or seizing fossils. Does anyone have any advice on this? Thanks!
