    A big one

    From the album: Late Jurassic belemnites of European Russia

    Lots of belemnites in Peski quarry, but they are either small or partial. This is a rare big Callovian (?) specimen
  2. I hadn't visited one of my favorite Callovian sites in the Wutach Valley since last November, so since the temps have been moving up and above 30°C. over the last few days, I figured that the muddy slopes there were probably dry enough by now for me to have a go at it again. No worries about sunstroke either, since the site is in the shady woods. I spent about 5 hours at the exposure and managed to come up with a few good finds. Here are some photos of the extrication procedure. It's pretty slow going here, since marl

    Russian fossil sites

    Hi all In this topic I'll give a brief overview of Russian fossil sites and typical fossils. I focus on the Jurassic as my main field of interest. The method used here is analyzing regional and temporary breakdowns of the number of specimens, shown by amateurs on Russian fossil resources, mainly ammonit.ru (about 40.000 finds). Unfortunately the overview has a inevitable bias towards the sites and fossil types attractive to the largest number of amateurs and downgrades those that are remote, less popular or less productive. The material is presented from an amateur's point of

    Unidentified Jurassic marine reptile bone

    Hi all, I've had the below piece in my collection for a number of years now, having acquired it thinking it was a juvenile plesiosaur propodial. It comes from the Oxford Clay of Peterborough and is of Callovian Jurassic age. However, when recently doing some research towards answering another question on TFF, I realised that - even though there's some plastic deformation going on - it doesn't quite look like the juvenile plesiosaur propodial I have from the rhaetic at Aust, nor does it look like a plesiosaur propodial

    Pachycormidae indet. - 'Hypsocormus' sp.

    From the album: Oxford Clay Fauna

    Pachycormidae WOODWARD 1895 indet. Jurassic, Callovian Oxford Clay, Peterborough Member [ A ] Orton Pit [ B ] Hampton Lakes, Peterborough, Cambridgeshire, UK Teeth from indeterminate, predatory pachycormid fish. Likely pertaining to either 'Hypsocormus' leedsi SMITH & WOODWARD 1889 or 'Hypsocormus' tenuirostris SMITH & WOODWARD 1889, which can be distinguished only by characters of the rostrum. Neither species actually belongs to Hypsocormus WAGNER 1860 according to MAXWELL et al. 2020, but are closer to more derived, macropredatory pachycormids like Orthocor

    Caturus porteri

    From the album: Oxford Clay Fauna

    Caturus porteri RAYNER 1948 Jurassic, Callovian Oxford Clay, Peterborough Member Must Farm, Whittlesey, Peterborough, Cambridgeshire, UK A scale from the medium-sized caturid Caturus porteri RAYNER 1948.

    Caturus megadontus (?=Osteorachis leedsi)

    From the album: Oxford Clay Fauna

    Caturus ?megadontus MARTILL 1985 (?= ?Osteorachis leedsi WOODWARD 1897) Jurassic, Callovian Oxford Clay, Peterborough Member Kings dyke, Whittlesey, Peterborough, Cambridgeshire, UK A tooth of the large, macropredatory caturid Caturus ?megadontus MARTILL 1985. MARTILL & HUDSON 1991 consider this species potentially synonymous with the contemporaneous and highly fragmentary caturid ?Osterorachis leedsi WOODWARD 1897, which would make ‘Caturus leedsi’ the valid name for this taxon.

    Marine Predator Coprolite

    From the album: Oxford Clay Fauna

    Coprolite Jurassic, Callovian Oxford Clay, Peterborough Member Hampton Lakes, Peterborough, Cambridgeshire, UK A coprolite from an indeterminate marine predator, showing inclusions of nacre, partially digested bone, and fish scales of Pholidophorus? sp. (an indeterminate pholidophorid) and Coccolepis sp. (an enigmantic coccolepid).

    Oxford Clay Metriorhynchid Teeth

    Hey everyone! Continuing from the other ID thread, I’d like to hear your opinions on another recent acquisition from the Oxford Clay: a group of associated metriorhynchid teeth. Now, there are several metriorhynchid taxa described from the Oxford Clay Formation: Gracilineustes leedsi, Ieldraan melkshamensis, Suchodus brachyrhynchus, Suchodus ?durobrivensis, Thalattosuchus superciliosus, and Tyrannoneustes lythrodectikos. Pretty much all of them have decent descriptions of their dentition available, so comparing these teeth to the literature facilitates the

    Todiltia schoewei (Dunkle, 1942)

    Alternative combination: Leptolepis schoewei. Taxonomy taken from NMNH Catalog Number USNM V 17903. DIAGNOSIS after Schaeffer & Patterson (1984): "Middle Jurassic teleostean fishes of leptolepid grade, but differing from similar fishes in having only chordacentra until late in growth. The chordacentra receive perichordal additions only in the midcaudal region, and only in the largest specimens. About 50 vertebrae, 30 abdominal. Dorsal fin in the middle of the back with about 16 rays; anal originates beneath posterior edge of dorsal, with about 14 rays; pelvics beneath dorsal o
  15. The weather has been so accomodating lately, that I figured that the snow should be gone by now from the slopes of the Wutach area in southwest Germany. I'd been thinking about a particular spot in the Middle Jurassic Callovian and decided to spend some time there. Sure enough, the snow was long gone, so I could scramble down the slope to the site. There are a few other local collectors who visit this site fairly regularly, but it was obvious that no one else had been there yet so early in the season. So I first made a quick inspection tour and found a few blocks which had weathered out over t
  16. Eleganticeras

    Macrocephalites macrocephalus

    Found loose and already broken at Cayton Bay Scarborough. Matrix of ooliths about 0.4mm. Grid of 1cm squares Referred to plate 33:2 in British Mesozoic Fossils, Natural History museum, British Museum. Plate Very similar to my find except that the rate of increase in whorl fattening is greater than illustrated. Lateral tubercules correct. However every photo I've seen of M. macrocephalus has no tubercules. Is it what I've found in the book? The book was published in 1975.
  17. I guess as you get older, you get a little more crazy. I had sworn to slow down a bit, particularly after my exhausting hike down the mountain recently, so I'd been visiting easy-to-work sites like the ditch and the shark tooth exposure the last few weeks. But then my colleague told me that he'd opened up another section at the Callovian site in the Wutach Valley and that I should have a look at it. Maybe you can make some good finds. Well, why not? So off I went today. At this site you have to remove a lot of overburden to get at the good horizons and then you're whacking away at a hard

    6cm. herveyi zone Early Callovian Found in the Wutach valley.
  24. From the album: Middle Jurassic Ammonites from Southern Germany

    3.5cm. This specimen with its shell mostly intact shows the innermost whorls of this subspecies. The venter at this stage is flat, but it rounds off at a later stage and gets covered up as it grows. From the koenigi zone, lower Callovian. Found in the Wutach area.

    Another Multiblock

    We're still allowed to move about freely here in good old Baden-Wuerttemberg, so I figured as long as this is still the case, I'll mosey along to my spot in the Callovian in the Wutach Valley. A friend of mine has been working there recently, so I was hoping for some more fresh exposure and sure enough, he'd opened up some new possibilities for me. Spent the good part of the day prying and hammering and came up with a few nice things. Here's the first and probably the best which I just finished prepping this evening. A multiblock measuring 12x12x6cm with 4 x Choffatia sp. and a bit of belemnit
