The one on the left is a Mosasaurus cf. missouriensis from the Blufftown Formation in Barbour County, Alabama, the one of the right is a Hainosaurus boubker from the Moroccan phosphates. '' Next is a massive Stenopterygius cf. quadriscissus ichthyosaur radius paddle bone from Mörse in Niedersachsen, Germany (an unusual Toarcian locality that I didn't have fossils from in my collection yet) and an elasmosaurid cervical from Texas. While it's unfortunately unknown where the vertebra was found, preservation indicates this is likely Ozan Formation from the NSR, although the Gober Chalk Formation in Fannin County would also be an option. Finally, there's two rare plesiosaur teeth: the one on the left, based on patterns of striations, cf. Tricleidus seeleyi from the Bathonian of the Stonesfield Slate Series and the one on the right the pliosaurid Hastanectes valdenis from the Valanginian Stage of the Early Cretaceous of Hastings in East Sussex. Very cool and amazing stuff again@pachy-pleuro-whatnot-odon ! I received a nice Plesiosaurus tooth myself yesterday. More precisely, he comes from Werstbury Formation of South Cloucester, UK (Collectoin location = Aust Cliff, South Gloucester). The tooth is 32 millimeters long. 5 Link to comment Share on other sites More sharing options...

I had intended to join in the bidding towards the end still, but was so tired after coming home from a day in the Winterswijk quarry that I completely forgot! I guess that saved us a bidding war, and I'm glad the tooth ended up going to you Looks really good, and still something I'd like to add another specimen of to my collection at some point 'There's nothing like millions of years of really frustrating trial and error to give a species moral fibre and, in some cases, backbone' -- Terry Pratchett Link to comment Share on other sites More sharing options...

pachy-pleuro-whatnot-odon Posted June 2, 2023 Share Posted June 2, 2023 (edited) So my latest score of fossils... First up is an ichthyosaur tooth, probably Ichthyosaurus communis, from Hock Cliff in Gloucestershire in the UK, measuring in at about 1.5cm. This is a rare locality and ichthyosaur remains are not very common at this locality. My next item is about 10x larger at 15cm. It's a beautifully preserved pliosaur vertebra. Unfortunately, it came without associated locality data. However, preservation and adhering matrix suggest the Oxford Clay of Peterborough (however, @paulgdls and @DE&i, please correct me if I'm wrong). From the positioning of the rib attachments/parapohyses, it's a cervical, and looking at the diagnostic features - overall rounded shape of the vertebra; central nutrative foramen without mamilla; absence of a ventral keel; ventral lip on the anterior articular surface; subcentral rugosity; narrow groove encircling the articular surface; and the shallow ridges between the rib attachment sites and the start of the neural arch - it can probably be attributed to Simolestes vorax.

Hi Lovely ichthyosaurus tooth from Hock. Re. the pliosaur cervical vertebra. I believe it to be from Pliosaurus sp. of the Kimmeridgian. I have one which is very similar which came from Westbury quarry in Wilstshire before the Cement works closed. Tarlo (or Halstead if you prefer) called these P. brachyspondylus and referred to the ventral lip and rugosity which brachydeirus does not have. 1 2 Link to comment Share on other sites More sharing options...

Beautiful vertebra, and, indeed, seemingly very similar to mine! I did consider P. brachyspondylus for a while before I'd noticed the ridges between the parapophyses and base of the neural arch and had recognised the lip for what it was, but wasn't entirely convinced. And as so much of pliosaur identification focusses on the age of a specimen, I decided to try and figure out where the specimen may have come from first. Not being familiar with much more than material from Peterborough/Orton and Abingdon to compare with, I eventually decided to side with Orton/Oxford Clay, as pieces I've seen from Abingdon are much more yellow to orange and sometimes even deep tan in colour. This too didn't sit quite well with me, though, as the matrix that can still be seen to adhere to the vertebra is much more yellow in colour than I think you'd get from the Oxford Clay. The vertebra coming from a closed cement work which preservation I was hitherto unfamiliar with therefore makes perfect sense! And so too identification as P. brachyspondylus, the lip, rugosity, and even the nutrative foramen without mamilla. As that species was erected based on a series of vertebrae now lost; your vertebra comes from the Westbury quarry from which P. westburiensis is known and my vertebra looks extremely similar; it has been suggested that Westbury P. brachyspondylus specimens can be attributed to P. westburiensis; and the only opposition to this is two French specimens that may not be identifiable or may potentially be attributable to P. carpenteri, it seems possible to me that these vertebrae could, in that case, have come from P. westburiensis. So I might go with "pliosauridae cf. Pliosaurus westburiensis". Thanks for sharing! This has been really informative!

Misha Posted June 6, 2023 Share Posted June 6, 2023 Received this in the mail today. It's a cephalaspid partial tail from Ukraine, showing off those banded scales that line their bodies, giving them a segmented look. I think these fishes are really cool and while most know about their headshields the rest of their anatomy seems to get overlooked by a lot of people. It has had some prep work done to reveal a bit more of the part of the scales along the edge of the tail on the positive, but I think there is a little bit more that can be uncovered, especially on the other side of the piece. I might get it prepped up further in the future Lower Devonian, Dniester formation, Ukraine 6 Link to comment Share on other sites More sharing options...

Jaimin013 Posted June 13, 2023 Share Posted June 13, 2023 (edited) Suchomimus tooth Niger ~57-58mm (2.638-2.677 inches) in length! Received this rooted tooth last week. It's now my second largest Spinosaurid tooth after my Spinosaur tooth from Morocco and bigger than my recent Baryonyx that's about 55mm. Lovely distal and mesial serrations on both sides. I've been speaking to a friend recently who thinks based off claws that he has that it may well be potentially larger than Spinosaurus! The holotype isn't a grown adult. Yesterday, I saw some of their claws including one that is 33cm along the straight line, they are huge trust me! Much larger than any Spinosaurus claws from Morroco or the well known Baryonyx claw from the UK. Edited June 13, 2023 by Jaimin013 6 Link to comment Share on other sites More sharing options...
Echinoid Express Posted June 15, 2023 Share Posted June 15, 2023 Ooo, I've always got a thing or two coming in the mail or from an event, I'll have plenty to put here! These are some Miocene Scutellidae sand dollars from the Ternopil Oblast in western Ukraine that I received a few days ago. I've been digging around online for an identity, and I've narrowed it down to Parascutella cf. paulensis, Parascutella gibbercula, Parmulechinus sp., or possibly a combination of them. The exact locality isn't known but I do know the villages that they came from. There seems to be a lot of quartz sand beds in the area, and one specimen was still in the loose sandy matrix. Two of them had particularly interesting "bumpy" tests. Unfortunately, not every specimen survived the transport intact. They are particularly brittle, which may be an effect of being preserved in the sandy matrix. I attempted to glue a few back together the best I could but a few small specimens were basically obliterated. In addition to these, I also received a really cool Clypeaster urchin in the mail yesterday. This one's a whopping 3.175 Kg (7 pounds), and is around 20.32 Cm (8 inches) in diameter. Unfortunately, the only information I received was it's from Europe. I know Portugal and Italy have had similar Clypeaster fossils, as well as Morocco. It resembles Clypeaster portentosus, but ultimately I'm not sure. I've included my previously largest echinoid, a roughly 15.24 Cm (6 inch) diameter Clypeaster sp. from Morocco, on the right just as a comparison. 1 4 Link to comment Share on other sites More sharing options...
pachy-pleuro-whatnot-odon Posted June 23, 2023 Share Posted June 23, 2023 10 hours ago, PetrosTrilobite said: This time i like to add more marine reptile material in my collection. With the help of @pachy-pleuro-whatnot-odon i think i will avoid bad deals. So i need again some help. Is this Ichthyosaur tooth? (Sold as Eurhinosaurus but i don't think is easy id a genus with a tooth), photo 1 - 2 Is this a Nothosaurus tooth? (Photo 3 - 4) Nice teeth! They are indeed as identified. For this nothosaur tooth you can tell by the sharp-edged striations, the spacing between them, but mostly by the absence of a smooth area at the base of the crown - which differentiates it from tanystropheid teeth - whereas you can tell that the ichthyosaur tooth is Eurhynosaurus longirostris from the horizontal banding in the first photograph. This banding is very typical of both Eurhynosaurus and Excalibosaurus.

Echinoid Express Posted June 24, 2023 Share Posted June 24, 2023 I got this nice small Middle Ordovicia Asaphus cornutus in the mail earlier this week. It's from the Vilpovitsy quarry in the Saint Petersburg region of Russia. I'm not a massive trilobite collector by any means, but I do enjoy getting an odd one occasionally. I especially enjoy the St. Petersburg trilobites, they have nice colors and cool, unusual eye variations. It's around 4.6 x 3.3 x 0.8 cm (1.811 x 1.299 x .315 Inches). 5 Link to comment Share on other sites More sharing options...
