  1. A few new Cretaceous fossils in my collection

    Hey everyone Last week I went to a small mineral/fossil market/exhibition near Lille (northern France). The thing lasted the whole weekend (29th and 30th September) - I managed to get to it just a few hours before it closed. There wasn't much diversity in terms of fossils, but I did spot some rather neat stuff - including some cool vertebrate specimens Cephalic 'armour' of a small placoderm (don't really remember from where, tho... ) Well-preserved eurypterid from the Silurian of Ukraine Little array of dinosaur teeth from the Cretaceous of USA (I think the seller mentioned that they were from the Hell Creek Fm.) More dinosaur (and 1 pterosaur, bottom-left corner) teeth; including 2 Bothriospondylus teeth from Madagascar.. I'd have loved to buy them Well-preserved Keichousaurus from the Triassic of Guizhou province (China). I didn't only 'gawk' at the fossils, I also bought a few little things : 2 small ?Lepisosteus fish teeth from the Cenomanian (Cretaceous) of Cap Blanc Nez (coast of northern France) I'm rather pleased I bought this one... Associated cranial remains of a small frog (?Ranidae) from the Maastrichtian (Late Cretaceous) of the Hell Creek Formation (Montana, USA). Seller told me that stuff is fairly uncommon.. Well, that's it Hope you enjoyed this -Christian EDIT: The last item (thanks for pointing this out, @jdp!) is actually a Doleserpeton skull from the Permian of Oklahoma... not a Hell Creek Fm. frog skull -Apologies for any confusion

  5. Hello, I have been recently shopping around for fossil books that are more image heavy to look around at on my downtime, the few I have so far seem to be generally focused on all fossils and contain hardly any fossil vertebrates from the mesozoic or tertiary periods. Thus I am on the look out for any books that would be good fits, there was one I cannot remember the name for the life of me that I think is a large recent book that I've seen in B&N that goes over all time periods in full color with fossil photos/creature images, if anyone knows maybe which one that could be I was definitely on the lookout for it but any recommendations are awesome.

    FLYKOwswish this article has some bearing on the following issues: Mammal biochronology,the precise timing and/or speed of the G(reat)A(merican)B(iotic)I(nterchange),it contains some remarks on mammal taxa(however brief), magnetostratigraphic resolution from the Miocene to the Pleistocene, the closing of the Panama isthmus, and the possible diachroneity of mammal taxon appearances. There are NO taxa illustrated,and the authors' (infrequent)use of "heterochroneity " is unfortunate . If you have Woodburne(2012): this might be up your alley I liked it,but I'm weird that way

  9. This question just crossed my mind today, seemingly without provocation: What are the oldest known coprolites in the fossil record, whether from vertebrates or invertebrates? I know of Paleozoic coprolites, but is there any evidence of coprolites before that, perhaps from the Ediacaran? And if there are no pre-Cambrian coprolites recorded, what are the oldest known from the Paleozoic? I have a feeling that @GeschWhat might know a thing or two about this subject since, after all, she is the official Queen of Poopiness on TFF.

  12. Kem kem vertebrae

    I bought this partial vertebrae about a week ago from a moroccan dealer for a very good price (I'm currently trying to identify many vertebrate fossils from Kem Kem, and this is somewhat a pause between two spinosaurid caudal vertebrae and a very big crocodilian mandible articular bone). Since many of you are way more experienced than me regarding moroccan vertebrae, I'm searching for more opinions. This small/medium sized specimen lacks most of the processes, but has some recognizable elements. It is laterally compressed and has a small keel running in its ventral region. I identified It as a caudal vertebrae, and the dealer told me it was a theropod. I don't think he had the skills to seriously identify anything, and I can't understand if It really is a theropod or a crocodile.

  14. 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 Member is the youngest strata in the entire paleogene sequence of the Hampshire Basin (Late Palaeocene to Early Oligocene). The horizon was deposited in a shallow freshwater lacustrine environment on the low-lying Solent Group coastal plain of the southern Hampshire Basin. By the time the White Band was deposited average annual temperatures in the region were beginning to warm up again after the sudden and rapid cooling that marked the Eocene-Oligocene transition. Global sea levels were also beginning to rise. The Grande Coupure, the large scale turnover of European mammalian faunas had been and gone, and the endemic Eocene groups such as Palaeotheres, Omomyid primates, and anoplotheres had long vanished. The lake/pond system that deposited the White Band was home to aquatic plants such as Stratiotes and was fringed by patches of open woodlands of Sequoia, Pine, and broadleaf. With the post-grande coupure fauna now established the landscape was home to anthracotheres, hornless rhinos, hyaenodonts, bear-dogs, entelodonts, primitive ruminants, choeropotamids, and a myriad of smaller mammals including bats, adapid primates, rodents, insectivores, marsupials, and the otter-like pantolestids. Not to mention the alligators, birds, and freshwater turtles. 1. Worn fragment of Emys carapace 2. Possible fragment of crocodilian osteoderm? 3. Fragment of Bowfin skull bone 4. Isoptychus sp. cheek tooth. Theridomyid rodents like Isoptychus are the most commonly found micro-mammal throughout the entire Solent Group. This molar has been heavily worn which may suggest an older individual. Theridomyids were bipedal and foraged along the ground and in low trees. They also seem to have fed on the seeds of marginal aquatic plants such as Stratiotes, which may be the reason this individual was in the vicinity of the pond/lake. The Theridomyids were one of only a few Eocene mammal groups to survive the Grande Coupure and seemed to have survived fairly unscathed in terms of diversity etc. showing what hardy and adaptable rodents they probably were. 5. Fragment of M3 from a talpid, most likely Myxomygale sp. (just 1.5mm long!). Talpids (or as we call them today, Moles) were newcomers to Europe with the Grande-Coupure, arriving from Asia. Belonging to the tribe Urotrichini (Shrew-Moles) which are only found in North America and Asia today, Myxomygale may have spent most of the day underground in burrows before emerging at night to feed on invertebrates. Modern Shrew-Moles prefer moist habitats such as swampy areas, a habitat which was abundant on the low-lying coastal plain of the Oligocene Isle Of Wight. The taphonomy of the White Band is also interesting. Some specimens i.e. the Emys fragment and osteoderm are highly 'polished' and worn, suggesting transport prior to deposition. Whereas others such as the mammals and most fish material I've recovered are unworn and 'fresh' looking. I'm not sure what conditions could have caused this, and if anyone has any suggestions I'd be really interested. My take is that the mammals and fish were likely living in the immediate area, in and around the lake/pond, whereas the polished material is from animals living some distance away brought to the pond/lake by floods or streams etc. although I'm no trained geologist or palaeontologist. Thanks for reading, Theo
  15. East Coast fossil road trip

    Hello! Later this year I'm planning on moving from Florida back to New England. I was hoping to make the voyage into an interesting road trip... I've heard of several places in the Eastern half of the US where you can dig your own fossils. I know that there are some places in Georgia and the Carolinas that are good to find Megalodon teeth, and some places in the northern US that are good for finding trilobites... I'm up for anything interesting and was looking for suggestions on exact places, tour companies, people, anything that you can offer that might extend my collection on the trip!
  16. Unknown Gainesville Creek Fossils

    Hello everyone, I recently went fossil hunting in Rattlesnake Creek of Gainesville, Florida (Late Miocene) and uncovered many different fossils but three of them I am unsure of the identity of them. I believe one may be a type of vertebrae, but the others I can not place. The creek is shallow, relatively fast moving with a sandy bottom but many areas where gravel, fossils and stones accumulate. The first 4 pictures are of the same fossil, the next 3 of the the second, and the last 3 pictures of the last fossil. I would appreciate any attempts to help identify. Thank you very much!
  17. Hi, I've recently fully processed some matrix from the Lower Hamstead Mbr. that I collected back in November, and I thought I'd share some of my finds in a similar way to my Bembridge Marls Mbr. material. The matrix originates from a 'shelly' horizon in the Lower Hamstead Mbr. and was collected from fallen blocks at the base of a low cliff exposure at Bouldnor Cliff. The Lower Hamstead Mbr. overlays the late Eocene Bembridge Marls and dates from the very earliest Oligocene epoch, approximately 33.75 - 33.5 million years ago. To put the finds into an environmental context the Lower Hamstead Mbr. was deposited during a period of rapid global cooling and drop in sea levels associated with the onset of antarctic glaciation (Oi-1). The cooling and eustatic change had begun in the late Eocene, with the palaeo-environments of the Bembridge Marls becoming increasingly terrestrial towards the Eocene/Oligocene boundary. By the Lower Hamstead Member the southern Hampshire Basin was a low lying coastal plain with extensive wetlands, lakes, ponds and sluggish rivers flowing south east towards the early channel (at this time the channel was more a large embayment with only occasional connection to the North Sea). The dense sub-tropical forests of the late Eocene had disappeared and the landscape was dominated by open woodlands of pine, sequoia, and oak. The environment was much cooler and annual rainfall had significantly dropped since the Eocene, although temperatures would begin to rise again further into the rupelian and Hamstead Mbrs. The basin was surrounded by areas of chalk upland (still existing today) with forests of sequoia and broadleaf species. This dramatic climate change is likely what triggered the Grande Coupure, in which endemic Eocene mammals like the palaeotheres disappeared and were replaced with Asian groups such as carnivorans, rhinocerotids, anthracotheres, and a variety of other artiodactyls. The mammals of the dense tropical Eocene forests simply couldn't adapt fast enough to the new open environments of the Oligocene and ultimately failed to compete against the better adapted migrants. By the Upper Hamstead Member the mammals on the Hampshire Basin coastal plain are almost entirely of Asian origin. Therefore the micro-vertebrates lived in an environment of large scale climatic and ecological change, which I think adds another level of interest to collecting from this member of the Bouldnor Fm. The material I've collected so far is a lot more varied than the Bembridge Marls, but overall is less abundant. So far it's produced at least 3 fish taxa, 2 mammals, and an indeterminate piece of jaw which may be reptilian or mammal. 1. A skull element from a Bowfin (Amia sp.), these fish are very common in most horizons of the Bouldnor Fm. 2. A vertebra from a Bowfin (Amia sp.) 3. A damaged lateral scute from a Sturgeon (Acipenser sp.) showing the transition to a freshwater environment 4. An indeterminate piece of a tiny jaw, may be crocodilian although I'm not sure. 5. The nicest find of the lot, a lower incisor from the theridomyid rodent Isoptychus (ID'd by Jerry hooker from the NHM). These rodents looked similar to modern kangaroo rats, hopping along the ground on large rear legs. Bite marks on Isoptychus bones collected from Thorness Bay suggest that they were common prey for the bear-dog Cynodictis. 6. Finally 2 images of an unidentified mammal tooth. I'm unsure as to whether this is part of the tooth or the entire crown, but it doesn't appear to be from a rodent. Hope you all enjoyed the finds, Theo

  21. 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
  22. 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.

    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.
  24. 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
