  1. Hey everyone - It's Christian. For the past few months, I was inactive on TFF as I had a lot of schoolwork.. But now, I've got a lot more time on my hands - which means that I can get back to all things fossil related This of course includes making preparations for my 3rd Møns Klint Fossil Excavation (MKFE - the fieldwork aspect of my Møns Klint Fossil Research Program). I'll be going for 2 weeks, in mid-August - I'm really excited! As I said in a post from a few months ago, the collection policy of this MKFE is essentially the same as last time's (cephalopod, crustacean, echinoderm and vertebrate material). This time, though, there'll be a bigger focus on articulated and/or associated material - eroded sea urchin spines and belemnite fragments are getting too numerous... On the first days of the field trip, I'll have to do quite a bit of prospecting for new sites to work at, because there's a chance that the landslide spoil heap from last year has most likely been washed away by the waves. I'm already having some ideas of particular projects for this field trip, which include a comprehensive collection of washout microfossils - to determine relative abundances of various faunal groups. Another project is the in-depth analysis of fossil material from different layers of chalk - which I hope will yield some zone fossils. Of course, I'm still hoping to find a lil' mosasaur tooth I'll also use this field trip as an opportunity to donate to the GeoCenter Møns Klint some of the fossils I found during the 2nd MKFE. I'll keep you guys posted! Stay tuned I'm so excited to getting back there! -Christian
  2. Hello Fossil Forum community, This is my first post. My name is Ben and I recently learned about the Peace River. After getting my fossil collecting permit, decided to try my hand at it! I loved collecting trilobites and sea animals in upstate NY, so to know there is a place in FL with abundant, remarkable and unusual fossils, makes me so happy! I live about 45min away from Paynes Creek Historic State Park; here the creek and river join. I collected these fossils just past the border of the park. I would like your help to try to ID them, please! Where Paynes Creek (right) meets lazy Peace River (left) Here are some fossils I think I know, but I am still unsure. Horse tooth? Dugong rib bone? (very dense feeling, like lead): Left: barracuda tooth? Right: claw? Back of "claw": Front: Front, zoomed: Side: Many thanks for any help, I love this River! Thanks for your time, Ben

  12. 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

  16. 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

  20. 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.

  23. 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.
  24. Camping in the Campanian

  25. 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
