  1. Late cretaceous nodule horn armor spike?

    Good morning folks, I was sorting through a box of unknown fragments from surface collecting this summer. I inspected more closely this piece that looks like a spike. Not quite symmetrical. Looks like designed as potentially a partially lateral nodule or armor spike. I was referring to some past discussions on cerotopsian frill material and am curious if this may even be a frill spike?!? Any help would be appreciated. Thanks everyone.
  2. Pachycephalosaur skull cap?

    I found this piece while surface collecting along the red deer river. East of dinosaur provincial park boundary. Its weathered but very sturdy. I've looked at other skull caps and the undersides look different. This doesnt have all the brain case structures so I was hoping for some help on the ID. Thanks
  3. From abstract: Some authors recognize three Caenagnathid genera, others suggest only two were present, and there is considerable disagreement about which specimens are referable to which genus. This study aims to resolve this issue by reviewing the known specimens and using osteohistology, to establish a testable taxonomic framework of Dinosaur Park https://journals.library.ualberta.ca/vamp/index.php/VAMP/article/view/29362
  4. Vertebra Process?

    This is a small bone scrap I found in the Dinosaur Park Formation a few years ago. I just recently took a closer look at it, and I now think it’s a vertebra process. What do you guys think? Based on the texture of the second pic, is it possible to tell what kind of animal it is? I’m thinking ceratopsian (excuse the very rough sketch)
  5. I recently learned that the Dinosaur Park Formation and in general the Belly River Group is in Montana! In parts of Kennedy Coulee, Milk River Badlands, is this true?
  6. Tyrannosaur tooth

    Hi I’m wondering what are your thoughts on this Tyrannosaur tooth? It’s 1.25 inches and is from the Dinosaur Park Formation of Alberta.
  7. Late Cretaceous mammal fossils from North America

    Could someone help me find PDFs of scientific papers about mammal fossils from the Campanian-Maastrichtian of North America? I'm specifically interested in papers that deal with mammal faunas from the Hell Creek Formation, the Lance Formation and the Dinosaur Park Formation... Thanks for any help Christian
  8. A new theropod-related paper is available online: G. F. Funston & P. J. Currie (2020) New material of Chirostenotes pergracilis (Theropoda, Oviraptorosauria) from the Campanian Dinosaur Park Formation of Alberta, Canada. Historical Biology DOI: 10.1080/08912963.2020.1726908 For a long time, after it became clear that Caenagnathus and Chirostenotes belonged to Oviraptorosauria, and following the description of complete postcranial remains of Chirostenotes from the Dinosaur Park Formation of Canada, scientists debated whether or not Caenagnathus is a junior synonym of Chirostenotes, because CMN 2367, CMN 8538, and RTMP 79.20.1, despite overlapping with each other, lacked cranial material. A specimen from the Horseshoe Canyon Formation (ROM 43250, now recognized as distinct taxon Epichirostenotes curriei) found in 1923 was described by Hans-Dieter Sues in a paper published in 1997 and touted by him as confirming synonymy of Caenagnathus and Chirostenotes due to presence of cranial material in that specimen. Not all scientists, however, were convinced that Caenagnathus was the same genus as CMN 2367, and studies in the previous decade indicated that more than one caenagnathid mandibular morphotype existed in the Dinosaur Park Formation. Now, UALVP 59400, the first articulated Chirostenotes specimen to preserve cranial and postcranial material, shows that Caenagnathus and Chirostenotes are separate taxa, even though it's clear from the description of the younger genus Anzu that Chirostenotes and Caenagnathus belong in the same family (Caenagnathidae). That said, does anyone have a copy of the above-mentioned paper I could look at, given that UALVP 59400 is the first bonafide Chirostenotes specimen with cranial material that overlaps with the Caenagnathus holotype?
  9. My Tyrannosaur research

    Hi I decided to make a post about my main research project right now on Campanian Tyrannosaurs specifically Daspletosaurus. Today I have found something to tell teeth from the Judith River Formation and Dinosaur Park Formation. This could also do with the Tyrannosaurs prey or locality. I found out that Judith River Formation Tyrannosaur teeth serrations are more circular and more round compared to the same time Dinosaur Park Formation Tyrannosaur teeth serrations. The Dinosaur Park Formation Tyrannosaur teeth serrations are more longer skinner and more chiseled like but not like other Tyrannosaur teeth from other areas like T. rex’s teeth serrations. Certain Tyrannosaurs in different areas and times would/could of had unique serration morphology probably dew to there prey. I did this on multiple teeth from the Judith River Formation and Dinosaur Park Formation to strengthen my hypothesis. Any opinions on this topic would be great. I will post more on my research here on this and other topics on the Tyrannosaur/Daspletosaurus. I have been doing research on this Daspletosaurus from the Dinosaur Park Formation and it’s close relatives because it was the first dinosaur fossil I’ve ever found. I’ve liked fossils and dinosaurs since I was 2 but in 2018 I went to Alberta and found my first dinosaur fossil which was a fossil from the Dinosaur Park Formation Daspletosaurus sp. Thats why I have been researching on this topic. The serrations I found on Dinosaur Park Formation Tyrannosaur teeth. The serrations I found on Judith River Formation Tyrannosaur teeth.
  10. Hi I found some of my photos from when I went to Alberta in 2018. I will post more tomorrow but I found this in particular really cool. It’s a comparison of the Dinosaur Park Formation, Dinosaur Provincial Park and the Horseshoe Canyon Formation, Horseshoe Canyon Drumheller. Both photos by me in 2018 I had them side by side each other. It just shows the different Ecosystems that where here millions of years ago!!
  11. My Canada fossil project of 2020

    After getting my Horseshoe canyon formation Hadrosaur and Ceratopsian fossils I decided to set a goal for 2020. To get dinosaur and and other fossils from the Carboniferous to the Cretaceous from around Canada formations. If anyone could help me out with this please PM me, it would be much appreciated. Thank you!!
  12. Hi I just bought these two dinosaur fossils from Alberta Canada. A Ceratopsian vert and a Hadrosaur metatarsal. The colouring and look/preservation of the Hadrosaur metatarsal makes me think they didn’t come from the Horseshoe canyon formation like it says but instead the Dinosaur Park formation. since it doesn’t give much information other then the Horseshoe canyon formation it’s possible, Thanks for future help. Ceratopsian vert
  13. Dinosaur park formation hunting

    Hi I was wondering where are some good spots for fossils in the dinosaur park formation outside of dinosaur Provincial Park thanks
  14. Centrosaurus Bone

    Hi I recently found out what this bone came from from my first post I turns out it’s from a Centrosaurus Aperatus I found out from a Centrosaurus leg bone that looks exactly like this from the Centrosaurus bone bed in Dinosaur Provincial Park Alberta Canada open to any opinions.
  15. Stegoceras vertebrae!

    Hi I recently found theses online are they Stegoceras vertebrae? the small ones are 0.5 mm to 13 mm the larger ones are 0.7 mm to 15 mm and there from the dinosaur park formation of Alberta thanks.
  16. Hi everyone I just read that a New pterosaur has been named it’s called Cryodrakon Boreas it’s name means cold dragon of the North wind it’s wingspan was 32.8 feet and it’s diet consisted of baby dinosaurs mammals and lizards it was found 30 years ago in the dinosaur park formation of Alberta Canada then it was thought to be a Quetzalcoatlus until 30 years later it was studied and is now its own genus here’s to learn more.
  17. 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 identified as the second premaxillary tooth of S. langstoni. The morphology and wear patterns suggest that these may have been specialized for preening feathers. Zapsalis is one of those tooth taxons and brings into question if its indeed valid or just synonymous with Saurornitholestes. The paper makes the following statement "The similarity between the premaxillary teeth of Saurornitholestes and Zapsalis show that the latter is a dromaeosaurid and suggests that the two genera are synonymous. However the differences suggest they are distinct at least at the species level. Pending the discovery of additional Associated skeletal material from the Judith River formation of Montana it is recommended that the two genera be kept separate." The holotype tooth of Zapsalis (right) from the JRF is slightly different than the Saurornitholestes tooth. See Fig. Might just be tooth to tooth variations. https://anatomypubs.onlinelibrary.wiley.com/doi/10.1002/ar.24241#.XXZqJ1PoYmg.twitter Cranial Anatomy of New Specimens of Saurornitholestes langstoni (Dinosauria, Theropoda, Dromaeosauridae) from the Dinosaur Park Formation (Campanian) of Alberta Philip J.

  18. Literally Rattled

    Hiking on another beautiful spring day near Manyberries AB. Found some dinosaur bones, mostly broken pieces. Hadrosaur, ankylosaur, tyrannosaur, raptor, croc, turtle, ...rattlesnake! I love it when they rattle at you from under the sagebrush from 3 ft away...so polite of them! Among other things, i found this strange specimen. It looks very ...dinosaur-like
  19. 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?
  20. Dinosaur park formation fossils

    Does anyone have photos of fossils from dinosaur provincial park Alberta if so can you send me them because I’m doing reaserch on the dinosaur park formation
  21. Some of my stuff

    I've not been able to get on this site as much as I would have liked to since I joined only a few months ago. I have a few bits that were left to me and I hold very near to me. Nothing here is for sale, but I just wanted to share some pictures of my collection. Please feel free to correct me, as I've self taught myself what some of these pieces are. My cousin's mother-in-law was one of the 1st amateur female paleontologists in Alberta and she has long passed and her item were given to me.

  22. This report is a bit late, but better late than never! During late July through to mid August 2018 i was on a research trip to study a new Canadian dinosaur footprint site for my Masters degree project. I am based in Australia, and this was the first time i had been to Canada! So of course i had to make the most of it and pay a visit to the world renowned Dinosaur Provincial Park in southern Alberta, arguably the richest site in the world for dinosaur fossils. The park is the best exposure of the Dinosaur Park Formation (which it is now named after), which dates to about 76.5 million years ago during the mid-Campanian. I had long read about this location and watched it on documentaries for so many years growing up as a kid. Finally being there in person was very surreal! I was quite lucky and managed to go on a long, extended walk through the park with one of the guides for about 6 hours in total. In this relatively short amount of time i observed so many amazing fossils. I must have been completely desensitised within the first 30 minutes! It really is incredible how much fossil material there is lying all over the park. In Australia, whole scientific papers are written about isolated or fragmentary dinosaur bones, yet here they were just lying everywhere! The pictures really speak for themselves. As said, all of these fossils were observed in the field during a single days visit to the park. As this is a World Heritage site, nothing was taken, all finds were put straight back onto the ground after i took these photos. It's a VERY hard thing to do, but rules are rules. The only thing that was removed from the park on my trip was my best find of the day... a near-perfect 5.3 cm tyrannosaur tooth from Gorgosaurus!!!! This find was too special to leave behind, so the park tour guide GPS marked the location and brought it back for display, likely at the visitor centre or as a demonstration piece for their guided tours. To say that i have found a tyrannosaur tooth is a great honour! You may remember it from the July 2018 VFOTM poll. Without further ado, here are the pics! It is going to take multiple posts to fit them all in, so scroll all the way down to see them all! Various dinosaur vertebrae. Everything from hadrosaurs (duck billed dinosaurs) and ceratopsians (horned dinosaurs) to theropods (two legged meat eaters) and ankylosaurs (armoured dinosaurs). These were so common! I would probably pick a new one up every 5 minutes or so. Ankylosaur tooth
  23. My June expedition was super fun and interesting to see what I could find. I have lots of unknowns and lots of fossil material that others will be able to help id. Thanks in advance for all those that join the discussion and help me figure out my library of dinosaur fossils.
  24. I went out for a fossil hunting trip to southeastern red deer river valley in southern Alberta and I found material from tyrannosaur, raptor, hadrosaur, ceratopsian, turtle, croc, and fish. I even found a snail shell fossilized out of ironstone. I am struggling with the ID on two of my finds. This claw I think might be ornithomimus. But the tip is broken and also very stout. At first I thought it was just broken but I'm thinking it is unusually short. The other is a tooth that I have not seen before. After some research I'm guessing Pachycepholusaurus?
  25. New Ornithomimid from Alberta

    A new Ornithomomid, Rativates evadens, from the Dinosaur Park Formation is described in this paper. SVP paper paywalled for non members http://www.tandfonline.com/doi/abs/10.1080/02724634.2016.1221415?journalCode=ujvp20
