  3. 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 Insect Bed, which produces finely preserved insects, feathers, leaves, and lizard skin impressions). Generally however, the Bembridge Marls were laid down in a sluggish lagoonal/estuarine environment with areas of wetland and adjacent sub-tropical/tropical forests, in the southern regions of the Hampshire Basin. To the south were forested chalk uplands that are now the downs of the Isle Of Wight. There was also some fluvial influence from rivers flowing from the west, draining the uplands around Dartmoor in Devon. Fauna-wise vertebrates like fish and freshwater turtles are common, and mammal remains are rarely found (in comparison to the overlying Hamstead members which are rich in post and pre-grande coupure mammals), these include palaeotheres, creodonts, rodents, anoplotheres, choeropotamids, xiphodonts, and primates. So far I've only searched through a small amount of the matrix but it has produced indeterminate teleost vertebra, Bowfin teeth, fin spines, indeterminate fish premaxillae, and a very nice crocodilian tooth. (The quality of the images isn't always fantastic but I'm trying to find a way to work around it in the microscope's program) Isolated fish vertebra from teleosts are by far the most common micro-fossil, and I've collected more than 10 so far. Here's a nice example: Bowfin teeth are also quite common and vary in size from 2-7.5mm in length. Bowfins would have been ambush predators feeding on smaller fish and other vertebrates in the lagoons and estuaries. Based on vertebra I've found ex-situ on the beach it seems some of these fish were very large. (Close up of one the teeth) These pre-maxillae also seem to turn up from time to time and appear to be from some form of teleost. The closest match I can find is with some kind of Gadiform? And finally the best find so far, a crocodilian tooth crown. I spotted this on the surface of one of the matrix blocks. It's most likely from the alligatoroid Diplocynodon which was very common in the wetlands and rivers of Europe from the Palaeocene to the Miocene. Diplocynodon has also been found in the early Eocene marine deposits of the London Clay suggesting that they frequented both freshwater and brackish/coastal habitats. The matrix is nowhere near fully sieved and sorted through yet so hopefully there's a lot more micro-vertebrates in there! Hope this was of interest, Theo
  4. I'm doing a Ragnar run next week in Richmond, then I'll be spending a few days in the city. Just curious if there's any nice localities to hit up while I'm there. thanks -J
  5. Its Spring. A glorious day. prairie Crocus are in bloom, the Meadowlarks are singing and the sky full of migrating waterfowl. First outing this year into the badlands. Headed out just north of Jenner, Alberta and then a trek east along the Red Deer River. Age is Campanian ( Late Cretaceous) about 72 million mya. All terrestrial deposits. A 6 km cycle ride in and then hike another couple. About 3 hours looking for fossils. Its feast or famine. Some hoodoos sterile and then an area dripping with vertebrate fossils. This area also yields a few 'unknowns' All fossils catch and release.
  6. I wanted to let people know of this resource. It is an online digital catalog of fossils found in the Lance Formation of Wyoming. I know they have found over 24,000 fossils, but I don't know how many have made it into the digital image catalogue. This is the URL https://fossil.swau.edu/ I'm not sure how many species there are in the catalogue. When I've been on the dig I personally found mostly: Edmontosaurus annectens Nanotyrannus lancensis But I know they also have some of the following in the collection to name a few: Thescelosaurus neglectus Tyrannosaurus rex Pachycephalosaurus wyomingensis Triceratops horridus Dromaeosaurus albertensis Trodoon formosus Leidyosuchus sternbergi Aublysodon lancensis Testudines Brachychampsa Cordata Crocadilia Unio There are more. Please pardon any spelling errors on any of the names. This data is from my Alma Mater, Southwestern Adventist University in Keene, TX. My mentor, Dr. Art Chadwick has been leading a dig every June for over 20 years at the dig site in Wyoming. In 2000 I asked Dr. Chadwick if there was anything he had need for the department. He said he wanted to buy a GPS device for the Dino dig. So I provided the department the funds they asked for to buy a fairly simple GPS device. They started using it that summer to map out the dig site and every single fossil they found from then on. No more staking out the dig with stakes and ropes. That first GPS revolutionized the way they mapped out the dig site. The GPS devices they use now are much more sophisticated and far more expensive. I'm not a paleontologist, but he has invited me to the dig every year since then. I'm not sure how many thousands of bones the have pictures of, but they say it is the largest digital catalog of its kind. Hope someone can find it a useful resource. Here is a description from the site. I couldn't copy and paste so I took a screen shot.
  7. Trade-Europe

    Hi! I would like to exchange these fossils for Miocene material or Mesozoic/Cenozoic echinoids/corals. Unfortunately, I can only trade with european members. 1-Mosasaur teeth;spinosaur tooth;otodus obliquus tooth (if you need more info, please pm me).
  8. The Colour of Fossils - Dr Maria McNama

    The Colour of Fossils - Dr Maria McNama Geological Society, Sepember 6, 2017 https://www.youtube.com/watch?v=Ewa8vflfipo “Dr Maria McNamara (University College Cork) explains how the emerging field of fossil colour has revealed unprecedented insights into the ecology and behaviour of ancient animals, describing how colour is preserved in ancient animals and how it can shed light on what they looked like, how they communicated with each other, and how the functions of colour have evolved through deep time.” Yours, Paul H.
  9. Hey FFFriends- I basically joined because I found this while kicking around tidepools on Agate Beach in Northern California. It was 50 feet from a whale carcass, so I think I just assumed for sake of size and locale it was a caudal vertebra from a whale. The find was obscured from years of tide pool living (kelp, worms, coralline algae), so after some delicate work I finally got it cleaned. Now I am less sure it's a vertebra. Can anyone help either confirm its origin in a Cenozoic whale tail, or is it something like a whale humerus shorn of its ball socket? A big stubby vestigial radius or ulna? Or a more terrestrial megafauna fossil? Please help! I have more angles, just let me know
  10. A quick survey

    Hello, everyone. I'm working on a side project right now and I could use the input of the room for this one. I'm wondering what people consider to be the best fossil collecting sites public and private in the contiguous 48 states. I'm looking for everything. Vertebrates and invertebrates, all periods, just the cream of the crop for everything. I don't need exact locations, so don't worry about sharing super-secret specifics. Thank you in advance everyone!

  12. Konservat-Lagerstatt in Northern Africa

    MAR Author&journal credibility:very high i will not post images of the fish here,but they are stunning. Instead I went for the invertebrates Textuallly speaking,this caught my eye: "A few fragments of fern fronds (Fig. 14) were encountered with additional examples seen in fossil dealers’ storehouses in Erfoud on a similar matrix. All are preserved as orange/brown goethite films similar to those encountered in plants from the Crato Formation of Brazil" NB:"After submission of this paper Cavin et al. (2010) published a paper in which the Gara Sbaa locality is discussed in the context of other Moroccan Early Cretaceous vertebrate assemblages, referring to the Gara Sbaa assemblage as the Agoulti assemblage."

  14. So, as some of you may know, I'm currently attending UF seeking a degree in geology, with post-grad in Paleontology. The most important reason I decided to do this (among many)at the ripe age of 33 was an inspiration to merge the knowledge of amateur paleontologists with professional paleontologists. I've had this idea that technology may be able to close the gap and eliminate the animosity between these groups, while at the same time actually encouraging and promoting fossil distribution. It is an ambitious goal that requires all those respected and knowledgeable in their field(amateur and professional) to work towards a common goal. I've written a simple proposal and outlined my plan. I've included the names of the Florida Museum of Natural History's paleontologists(as it is public record), but I would also like to include some knowledgeable amateur paleontologists to work towards this goal. If you are interested please contact me, and I will send you a copy of the proposal. I would like to note that this is not a commitment to anything,your information will not be shared, and you will only be contacted by me(maybe). HH joshuajbelanger@gmail.com -J
  15. Few from Peace River 2/25/17

    Just a few finds from today I'm not quite sure about or at all. First one that looks like a vertebrae (1st 3 pics) is 1.75" long. 4th and 5th are the same as are the 6th & 7th. Trip report is upcoming
  16. way to go ,Bob

    RCVP&E A book that's been in my bookcase since it was published,and now it is digitized NB: large file a note on quality:scan could have been slightly better,but i've seen some eyesores,and it's a lemon in the basket,anyway. Do not expect anything more than a solid osteology textbook. Pretty solid,as thing go. Given its publication date: scarce or nonexistent histology,no tomographs,no GIS applications in taphonomy,etc. Fot those of you who hate unweighted character states ,branch swapping,and strict consensus trees:not in tHIS book Enjoy
  17. Books/canada

    Book Freebies for someone in Canada. I've boxed up some publications on vertebrates. These are doubles and ones I wont use ...to give away. In used but decent shape. Some notes in margins. The two shark tooth books are large and heavy. No need to compensate me for postage but I ask that you make a equivalent donation of the postage to your local SPCA. (Last box to Maritimes was $34). Note...I will send these as a group to someone with an specific expressed interest in the subject. If I dont respond, they are spoken for. PM only, please.
  18. Vertebrates and invertebrates-miocene

    This weekend I went on a quick hunt with my family to Sesimbra's Miocene (Calcarenitos e margas da Foz da Fonte-Burdigalian). It was a really nice hunt...And I brought home some quality (IMO) fossils. However, the documents I've been read about this site are not very specific about taxonomic informations. So, I would like to ask for some help identifying my finds. Invertebrates -Ficidae (maybe Ficus sp.)
  19. Winter hasn't yet arrived so we went for what will likely be our last badland adventure of the year. As usual, more of an all around Nature outing than just fossil oriented. The cooler temperatures are a welcome as much easier to scramble up and down the canyons. However, short daylight hours limited our hike to a couple of hours. You can tell from the deep shadows that we're approaching the shortest days. This is Late Cretaceous... Campanian. An area just down stream from Dinosaur Provincial Park. Although fossils on the surface can be collected in Alberta, these are all 'catch and release'. (We're almost fossils ourselves and downsizing the collection). It's only possible to identify most finds to a family level as the dino list in this area is quite extensive. Di on the look out for Tyrannosaurs.
  20. I'm looking at planning a trip to Montana this summer with my daughter who will be turning 7 that week. I've been looking at the Baisch ranch(aka daily dinosaur digs) in Montana as it seems the most flexible schedule wise. We planned on trying to go for a week to hunt Glendive in general, but would really love to spend a few days hunting vertebrates. We obviously plan to do this legally so this leaves us only a few options with that one seeming the best. I'm wondering what kind of experiences you've had if you've gone there. What is the quality of fossils you were able to acquire? I know it says on their page about keeping most fossils. Was there anything you weren't able to keep? Any recommendations on items to bring outside of what's on the page? We've never been vertebrate hunting before so this would be completely new to us. Thanks in advance.
  21. I ordered a different book from ebay and they sent me the wrong one. At least it's still fossil-related, but it's outside my area of interest. I don't know if this is worth anything to anyone, but if you want it, I'll trade it for a fossil. I'm more into inverts but it can be just about any fossil, it doesn't have to be very valuable! (I didn't pay a lot for the book...) Alternatively I could offer it for the cost of shipping. (I'll relist it in the sales section if necessary)
  22. Great weather so back into the Alberta badlands. This time to the Oldman Formation.This isolated locale is about 30 kms east of Dinosaur Provincial Park. Age Late Cretaceous (75 million years). Most exposures here are dominated by the Red Deer River but, instead, we hiked inland to a maze of steep sided canyons. I hadn't been here for a couple of years. Please excuse some of the dim photos as light is limited this time of year.
