  1. I try to get out dinosaur collecting twice a year and this year has been very good to me. Here are some quick field shots of SOME of my finds for this fall. I have a big prep job in front of we but I also use someone in Hill City to do some of my complicated work. Sites are in Montana and South Dakota all from the Hell Creek Formation. My Spring trip post have more specifics on the localities. My best find of the trip occurred on day 3 in Montana a complete dentary (lower jaw) with teeth of a Ceratopsian most likely Triceratops sp. The field photo show the jaw with lots of
  2. Another important dinosaur paper that is paywalled. Went the rental route again. The paper takes the first good look at the Skull of the Dromaeosaurid, Saurornitholestes langstoni from the Dinosaur Park Formation. It provided great insight into Dromaeosaurid's and specifically the dentition which we as collectors are most interested in. Similar species are found in Montana's Judith River and Two Medicine Formation. The biggest surprise were the premaxillary teeth, they are distinctive, and teeth previously identified in the Dinosaur Park Formation as Zapsalis abradens can now be i

    Fossil Gum Ball?

    Found this yesterday. Not perfectly round, but really close. Very smooth except the “eyes”. There is a pattern of sorts that looks like a crab, maybe. Diameter is the same as a penny.
  4. Hello!! This is my first time here and I was really hoping to get some assistance is identifying some stuff. Several years ago my uncle built a large workshop on his property and had has this huge pile of rocks in his backyard ever since. I am not positive of the whole story, but I do believe that the company he hired to dig for the foundation came across one, or several dinos, and just left the broken specimen in a large pile. I have several large chunks, this is only one piece, with the photos taken from several angles and ranges in an attempt to show the most detail. There are some weird li

    Strange NJ Cretaceous Fish Bone

    Hi everyone, I have this partial fish bone from the Late Campanian of New Jersey, 72 Ma. I have never seen this type of bone structure before, but for some reason it reminds me of some type of rostrum (billfish?). It is a little over an inch at greatest dimension. Any ideas are appreciated!
  6. Just got back from a trip to the badlands of Montana and South Dakota in the Hell Creek Formation.. Here are some photos of some of the bones I picked up at an Edmontosaurus site. My hope was to collect specimens fitting in a shoebox and I was fairly successful at that which was quite surprise since you dont get to choose what you find. The site is faily large and the area I was collected had about 6 foot of overburden removed a couple of years ago so there was only 12 inches left before I hit the layer. The layer in this area is about 17 to 20 inches thick, white lines. Nothing is pr
  7. A new paper is available online: Christopher R. Noto; Stephanie K. Drumheller; Thomas L. Adams; Alan H. Turner (2019). "An enigmatic small neosuchian crocodyliform from the Woodbine Formation of Texas". The Anatomical Record. in press. doi:10.1002/ar.24174. Scolomastax constitutes the youngest record of Paralligatoridae from North America, indicating that paralligatorids spread to Appalachia prior to the Western Interior Seaway forming.

    Late Cretaceous marine vertebrate's bone

    Hi TFF friends, how are you? I would like to have your opinion concerning the following fossil. It's a bone I found a while ago in the Himenoura formation, Santonian (Kumamoto Japan) and I forgot until I decided to clean my drawers. It has a quite distinctive shape and make me think to a sea turtle bone, a paddle or an ulna maybe. What kind of bone do you think it is? Any ID? I am not looking for the ID, I just would like to know what kind of bone it is.
  9. So I was rooting again around in the garage and found a couple plates I had bought a few years back and never tracked down an ID for. Tentative provenance was Paleocene from Montana. I found this article recently and was wondering if it could be one of the genera/sp described or one of the other genera mentioned in the discussion section. Trapa, Trapago, Fortuna, Quereuxia. STOCKEY, R. A., AND G. W. ROTHWELL. 1997. The aquatic angiosperm Trapago angulata from the Upper Cretaceous (Maastrichtian) St. Mary River Formation of southern Alberta. Int. J. Pl. Sci. 158: 83-94.

    2019 Alberta dinosaur fossils and more

    I have been out discovering some fossils and other cool stuff this spring. Lots of generally recognizable material but specifically I dont know what exactly I have here. Hopefully some of the enthusiasts and experts on the forum can help me out?

    Several NJ Cretaceous Non-Shark pathologies

    Hello TFF, I got a couple items from the Late Cretaceous of NJ that seem to be pathological. The first one, an Anomoeodus phaseolus tooth, seems to be very wrinkly and so I deemed it a patho. That is more of a verification as I haven’t seen a pathological one before. The second is an Ischyrhiza mira rostral blade that has a third carina on one of its faces and a slight flattening (flattening better seen in person). This is also a verification as I just didn’t expect to see a patho rostral. The third one is a bit strange. It is definitely a fish tooth. T

    NJ Well Preserved Turtle Peripheral

    Hi everyone, I got this interesting peripheral turtle shell from the Late Campanian Wenonah formation of NJ. It is not reworked and seems to be IDable. It also has some interesting shark predation marks on the top of the first pic. It is about 2.75” X 2.25” @non-remanié Thanks for any help!

  16. Very cool article on a Hell Creek Fm bonebed in Bowman, North Dakota A meteor impact 66 million years ago generated a tsunami-like wave in an inland sea that killed and buried fish, mammals, insects and a dinosaur, the first victims of Earth’s last mass extinction event. The death scene from within an hour of the impact has been excavated at an unprecedented fossil site in North Dakota.

    New titanosaur from Patagonia

    Hi, Is there a copy of the following paper: Leonardo S. Filippi, Leonardo Salgado & Alberto C. Garrido (2019) A new giant basal titanosaur sauropod in the Upper Cretaceous (Coniacian) of the Neuquen Basin, Argentina.

  19. Step aside Sue, the T rex. The attached article finally describes the largest T rex discovered from the Frenchmans Formation of Saskatchewan, Canada after being discovered in 1991 Abstract Here we describe an extremely large and relatively complete (roughly 65%) skeleton of Tyrannosaurus rex (RSM P2523.8). Multiple measurements (including those of the skull, hip, and limbs) show that RSM P2523.8 was a robust individual with an estimated body mass exceeding all other known T. rex specimens and representatives of all other gigantic terrestrial theropods (Pay

  21. Updated 1/17/20 I've taken a pretty firm position on the validity of Nanotyrannus ever since I spent some time looking at the Dueling Dinosaurs shortly after they were discovered. Subsequent to that, new information that I've become aware of just cemented my position. I'm interested in understanding the "truth" and have no problem looking at all available specimens that are in private hands or museums. The optics are very clear to me and I have difficulty understanding the debate. Collectors need to form their own opinion on this but I would like to share with you why I beli

    Trematochampsa

    Does anyone have a copy of the following paper that I could read: Louise M V Meunier, Hans C E Larsson; Trematochampsa taqueti as a nomen dubium and the crocodyliform diversity of the Upper Cretaceous In Beceten Formation of Niger, Zoological Journal of the Linnean Society, Volume 182, Issue 3, 17 March 2018, Pages 659–680, https://doi.org/10.1093/zoolinnean/zlx061

  25. Hi TFF friends, how are you? I am great, thank you for asking Yesterday I had I went to my favorite late cretaceous spot after an almost 3 month long forced break. So I decided to hunt all day long and went to few different spots with quite a good haul ( for me at least). First I went to an old Quarry in Kumamoto were the middle part of the Himenoura formation is visible. I hunted there few times in the past years and found a lot of ammonite's aptichii, Inoceramus and plants fossils. One year ago, the site was black and there
