    Finds from Thorness Bay

    Hi My wife and I found these three fossils yesterday at Thorness Bay on the Isle of Wight. They were beach finds rather than in situ but the rocks there are Bembridge Limestone and the Bembridge Marls of Eocene age (and pre Grande Coupure so older than 34ma). I think that A and B are mammal calcaneum but am not sure of species (or even if it is possible to identify to that level from the bones I have) - Any suggestions to help with identification or sources I could use to identify would be very much appreciated. Item 3 is a mammal jaw, I think a left mandible, I am pretty sure that

    Caudal vertebra or phalanx?

    Collected at Bouldnor on the Isle of Wight, and is about 33 million years old (Bouldnor Formation). This site produces a variety of mammals, turtles, crocodilians, birds, lizards, fish and amphibians. I am torn between labelling this a small caudal vertebra or phalanx. One end is unfortunately broken while the other is concave, with a rounded socket-like face to it. Measures 17mm long.

    Bird Pelvis Fragment?

    After having another look at one of my bone fragments from the Bouldnor Formation (Isle of Wight, UK), the closest match i have been able to find is a bird acetabulum, as circled in the diagram below. But i am not an expert on avian anatomy. Can anyone else offer any insight? @Auspex Specimen is approx. 33 million years old. The Bouldnor Formation on the Isle of Wight produces a wide variety of mammals, turtles, crocodilians, birds, fish, lizards and amphibians. Measures 29 mm at its longest. The 'socket' which i think may be the acetabulum is 12.5mm in diameter.

    Anthracothere Phalanx (found 2017)

    From the album: Fossils From Bouldnor, Isle of Wight

    Proximal phalange from an anthracothere, probably Bothriodon based on its large size (43 mm long). Collected on the coastline at Bouldnor on the Isle of Wight in the UK. Upper Hamstead Member of the Bouldnor Formation (approx. 32 Ma)

    Anthracothere Tooth (found 2014)

    From the album: Fossils From Bouldnor, Isle of Wight

    Tooth from an anthracothere, probably Bothriodon or Elomeryx. Collected on the coastline at Bouldnor on the Isle of Wight in the UK. Upper Hamstead Member of the Bouldnor Formation (approx. 32 Ma)

    Bothriodon Jaw (found 2014)

    From the album: Fossils From Bouldnor, Isle of Wight

    A large fragment of mammalian jaw belonging to the anthracotheriid Bothriodon. Collected on the coastline at Bouldnor on the Isle of Wight in the UK. Upper Hamstead Member of the Bouldnor Formation (approx. 32 Ma)
  8. G'day all! After three years since my last visit to the UK, i finally returned in December 2017 for another massive collecting trip across England. This was my most ambitious tour of the UK's Mesozoic and Cenozoic vertebrate deposits thus far, with 20 days of collecting across ten different locations. These were (in chronological order from first visit): Abbey Wood in East London Beltinge in Kent Bouldnor on the Isle of Wight Compton Bay to Grange Chine on the Isle of Wight Lyme Regis to Charmouth in Dorset Aust Cliff in Gloucestershire
  9. Hi, I've just got back from one of my collecting trips to Bouldnor Cliff and picked up an odd mammal tooth crown that I was hoping I may be able to get some help with. The specimen constitutes part of the crown and the roots of an as of yet unidentified tooth (possibly molar?). What struck me about it upon picking it up is that the morphology of the tooth and it's roots do not resemble the usual (and common) dental material from Bothriodont anthracotheres which constitute the vast majority of mammal finds from the upper Hamstead Mbr. I've compared it to the Bothriodon teeth and ja
  10. Hi, I've just got back from a collecting trip up to Hamstead Ledge this afternoon and came across a fairly rare find that I was hoping someone may be able to help with. It's the distal tarsometatarsus of bird found ex-situ on the foreshore. Bird material from the Bouldnor Fm. tends to be quite rare and this is the first piece I've actually ever come across so was really excited to find it! I was wondering if there were any diagnostic features on the specimen that would be able to take the ID further than "Aves indet.". If anyone has any knowledge of bird material then I'd really a
  11. Hi, It's been a while since I've put anything up on here so it figured it would a good time to share some of my finds from this spring so far. With such a productive winter the start of this spring on the Bouldnor Fm. coast was a bit slow with several trips in which little was found (odd for what is usually a heavily productive site) but as March and April came round the finds started coming in faster and better. Access at Bouldnor is now very dangerous and pretty much impassable due to thick and deep silt and mud which has covered part of the beach (which I found out the hard way
  12. Hi, Bit of a geological question here, I recently took this photo of some of the Upper Hamstead Member strata exposed on a headland at Bouldnor Cliff whilst out collecting. I really like this spot as the colour variation in the beds is really interesting. I've heard that the colour mottling in mudstones such as these can be indicative of the paleo-environmental conditions they were deposited in. Generally speaking these muds were deposited in ponds, lakes, and sluggish waterways on a low lying coastal plain. However, would it be correct to presume the redder areas indicate more ar
  13. Hi, I recently finished processing 4kg of matrix from a horizon in the Upper Hamstead Mbr. of the Bouldnor Fm. from Bouldnor Cliff and thought I'd share the results! The White Band is definitely the most diverse vertebrate fauna I've collected so far in my short time screen washing, with at least 2/3 genera of fish, 2 genera of reptiles, and 2 genera of mammals, it also has some interesting taphonomy. The White Band refers to a thick Polymesoda shell bed in the Upper Hamstead Mbr. and dates to approximately 33 million years bp during the Rupelian. The Upper Hamstead

    Anthracothere Mandible

    Partial crushed left mandible from the anthracothere Bothriodon collected from the Bouldnor Formation in two pieces. The first collected ex-situ on the 29/01/18, and the second on 13/02/18. P2 to M3 in-situ. P1 and M2 missing.
  16. Hi, I thought I'd share some of my best finds from what has been a brilliant start to collecting in 2018! The Isle Of Wight has been hit by heavy storms, with torrential rain and gale force winds, numerous times over the last month or so. This has caused some serious erosion and slipping to the soft clay cliffs and foreshore of the Bouldnor Fm. and the coast has been highly productive. I've made some of the best finds of my fossil hunting "career" (if that's the right term for it), including some very nice large mammal finds that I have dreamed of coming across for a while now.

    Rodent Cheek Tooth

    Cheek tooth from the theridomyid rodent Isoptychus sp. Collected through screen washing of matrix from the 'White Band' a shallow freshwater lacustrine horizon.
  18. Hi, I headed out for a full day of collecting at Hamstead on Saturday, and thought I'd share how it went. I reached the beach at Hamstead Duver around 9am and began searching the foreshore. The finds on this part of the coast are washed round by longshore drift, but it can be a productive section. This was definitely the case on Saturday, within the first 20 odd metres I picked up various pieces of trionychid carapace, Emys fragments, and the worn trochlea of an anthracothere humerus. I continued west along the coast before reaching the slipway (a disused boat launchi
  19. Hi, I thought I'd share some of my finds from what was a pretty good trip up to Bouldnor Cliff on Tuesday morning. This was my first collecting trip in over a month due to tides, being ill over Christmas and being generally busy, so I missed out on most of December. But hopefully I can start getting back into going twice a week again as usual. Low tide was at 09:48 so I decided to head for Bouldnor instead of Hamstead, as it's a lot easier to quickly access. My hope was that the prolonged stormy weather we've had for a couple of weeks now would have brought up some ni

    Crocodilian Bone ID?

    This small crocodilian fossil was collected on the beach at Bouldnor on the Isle of Wight in southern England. It comes from the Bouldnor Formation and is about 33 million years old. I'm certain it is crocodilian (from the small aligatorid Diplocynodon) based on the distinctive pitted texture. Scutes and vertebrae from this small croc are fairly common finds on this coastline. However this particular piece has stumped me, it is 3D and hollow on the inside, not like any scute i've picked up. I was thinking it must be some sort of skull element but i'd appreciate any help to rectify this!
  21. Hi, I collected some fossiliferous matrix yesterday from the Bembridge Marls Mbr. and Lower Hamstead Mbr. of the Bouldnor Fm. and was wondering if anyone could advise me on the best method to separate the clay from the micro-fossils. I've been interested in collecting micro vertebrate remains alongside the larger material for a while now and received a digital microscope for my birthday last week. I had a go at extracting some from some smaller pieces of matrix I collected last weekend (by simply washing the clay around in a bowl and then repeatedly decanting it) and produced a ro
  22. Hi, I've recently been sorting through my freshwater turtle pieces from the Bouldnor Fm. and have come across a couple of fragments that don't resemble the normal finds of Emys and Trionyx. I remember collecting them at the time and thinking how weird they looked but I presumed the markings were the result of damage etc. so didn't give them much thought. Interestingly I've found a reference in a paper from 1890 on the fossil chelonians of the Isle Of Wight that states: "There is a third species of chelonian, the remains of which are comparatively rare, and the outer surface of who
  23. Hi, I thought I'd show some of my first micro-vertebrate fossils from the Bembridge Marls Mbr. of the Bouldnor Fm. I collected around 2kg of matrix from one of the 'shelly' estuarine horizons in the lower part of the member at Hamstead Ledge, and am really pleased the results so far! The Bembridge Marls form the basal member of the Bouldnor Fm. and were deposited between 34.0 and 33.75 million years representing the final 250,000 years of the Eocene epoch. The depositional environment varies throughout the member and many beds are laterally discontinuous (like the Inse

    Bouldnor Cliff Phalange

    Hi, I'm back again with another mammal foot bone from the Bouldnor Formation. I collected this phalanx this afternoon whilst out collecting at Bouldnor Cliff and am having a nightmare trying to identify it. It's asymmetrical and quite 'heavily built' in comparison to your usual anthracothere phalanges which makes me think it might not be Bothriodon. It's slightly damaged around the proximal articulatory surface but other than that is pretty much intact. It's 4.2cm long and 2.1cm wide. I did check Anoplotherium as I remembered it having short compact phalanges and the remains of se

    Rodent Incisor

    Lower incisor from the theridmoyid rodent Isoptychus. Collected from a thin lacustrine horizon in the Lower Hamstead Member of the Bouldnor Fm. at Bouldnor Cliff, an early Oligocene locality on the northwest coast of the Isle Of Wight, UK. Identified by mammal specialist Jerry hooker from the Natural History Museum.
