    Juvenile Tyrannosaurus rex (2)

    From the album: Dinosaurs

    Tyrannosaurus rex (Juvenile) Hell Creek Fm., Garfield Co., MT, USA ~ 13 mm crown height ^wonderful art by RJ Palmer Fossil in Collections: http://www.thefossilforum.com/index.php?/collections-database/chordata/dinosaurs/juvenile-tyrannosaurus-rex-tooth-r2081/ The lighting wasn't very good, so I might redo this photoshoot later.
  2. What is the most likely attributable identity for the Tyrannosauroid remains at Phoebus Landing of the Tar Heel Formation? What I am referring to specifically are bones documented in Baird and Horner's 1979 paper which speaks of a distal third of a right femur that is attributed to cf. Dryptosaurus and is smaller than the holotype of D. aquilunguis. It is also compared with Albertosaurus which shows similarities as well but that's expected with Eutyrannosaurs. Also there is another distal left femur of a tyrannosauroid shown to be found in a Hypsibema bonebed and origi
  3. Hello everyone, I hope im posting in the right topic section, if not please guide me Im looking at a Suchomimus Tooth for myself im a new collector. I found one that looks really cool , A bit Ivory-like patina. I found out that most of them are much darker. So my only fear was: is this a Suchomimus tooth or not? Please find some images of it bellow. The tooth measures 50mm (5cm or 1.96 inch) its found at Gadoufaoua, Téneré Desert, Niger Thanks for your guidance Best, Phos_01

    Paper Request

    I’ve been trying to access the paper “Preliminary analysis of a sub-adult tyrannosaurid skeleton from the Judith river formation of Petroleum county, Montana” but have had no luck, I’ve even tried Science Hub but still no luck. I’m wondering if anyone has a copy or possibly photos of the paper so I could read it. Any help is greatly appreciated!

    Alberta Gold

    Went on a wild fossil hunting trip today out on private land in the Dinosaur Park fm. and found something that I’ve since reported to the Tyrrell. My best guess is a partial hadrosaur tail. The specimen is about 3 feet long by 1.5 feet wide. There was no other associated material nearby but there may be more of this dinosaur under the surface. I’ll also post a few of my favourite surface finds for today. I have a before and after photo of a vert, a large partial rib and some tyrannosaur teeth & a croc tooth.

    Hell Creek Tyrannosaur Denticle Variation

    From the album: Dinosaurs

    Comparison of Tyrannosaur denticles (serrations) from the Hell Creek Formation. All of the images are set to the same scale Some differences are likely associated with position in the mouth and/or feeding wear. So, this may not be a perfect illustration of purely ontogenetic variation. The adult T. rex denticles are from an unknown position and carina (being from a tooth fragment), the juvenile T. rex denticles are from the distal carina of a right (rear?) maxillary tooth, and the infant T. rex denticles are from the distal carina of a posterior tooth. The Nanotyrannus

    March Has Been Pretty Nice...

    ...so I headed out to find some Dinos. All fossils dinosaur park fm. Got some new land permissions so I have lots of area to wander. Here’s some notable finds from today. Large hadrosaur (or possibly ceratopsian) foot bone, large hadrosaur foot claw, tyrannosaurid caudal vert, possible tyrannosaurid toe bone, and some indet. fused verts. These will be pictured, there were various other verts and smaller bones found that I may post later.

    T.rex skull?

    Greetings, I have now received some pieces of bone, it should be pieces of bone from the Tyrannosaurus' head ... it should be one individual ... if anyone can confirm or refute it, or even know which part of the skull it is. ..I would be very grateful ... for some pieces, I already have an idea where they fit ... I photographed every piece of bone 5 times ... you can see a part of the surface of the bones at each one .. I just don't know if I'm wrong, so I'd rather ask here, the more erudite ones ... thank you for your time
  9. I have here five Therapod teeth from the Judith River Formation of Hill County, Montana. Four are partials, and one is a small and complete. They were identified as Tyrannosaurs, but I'm wondering if that's accurate, and if it's possible to narrow them down further. It's probably a long shot, but I felt it would be useful to ask here where there are many more knowledgeable about theropods than I am. I've offered different angles, sizes, and serration counts. Thank you, Bellamy

    T.rex Tooth?Please ID

    Please identify this tooth, unfortunately I do not have more photos available, nor the location of the find, or any information, but I think that identification is possible anyway ... maybe the color, the guidance of the curve will reveal something ... thank you for your time.Luk

    Tiny Lance fm. Theropod Tooth

    Hi everyone, tonight I want to share with you one of my favorite finds from the summer, this absolutely tiny theropod tooth I found looking through anthill matrix in Wyoming's Lance formation. It's currently the smallest theropod tooth in my collection and it's always an interesting contrast when compared to my largest personally found tooth (a Tyrannosaurid from Judith River). It's about 3 mm in length and a bit over 1.5 mm in width. I believe the serrations have been worn off as they are incredibly faint in some areas and absent in others. I'm not sure if the way the light gleans off t

    Tooth - Tyrannosauridae indet.

    From the album: Dinosaurs

    Species: Tyrannosauridae indet. Age: Cretaceous (Campanian), c. 75 million years ago Location: Two Medicine Formation, Montana, United States Pretty fragmentary tooth, but cool to have nonetheless. There are three species of tyrannosaurids present in the Two Medicine Formation (Daspletosaurus horneri, another currently unnamed species of Daspletosaurus, and Gorgosaurus libratus), so the tooth is not identifiable down to the species or genus level.
  13. Hi I’m looking into buying these three teeth and am wondering if they look good to anyone? Like restoration, repair, composite? And if it’s possible to identify the species? Thank you for any feedback! baby Diplodocid indet, Morrison Formation Theropod indet, Morrison Formation Tyrannosaur indet, Judith River Formation

  15. I recently learned that the Tyrannosaur femur I discovered in Dinosaur Provincial Park in 2018 (the same day I discovered my Hadrosaur Trackway, actually only 10 minutes apart from each other) is at the Royal Tyrrell Museum. I originally reported it in late 2018 and the Dinosaur Provincial Park team collected it and brought it to the field station, they then gave it to the Tyrrell and it’s been there since. But the thing is I never knew this until recently as I asked Caleb Brown about it when I was asking him about the Hadrosaur Trackway, he said it was collected by another group which turne

    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 Tyrannos
  17. Hello, Been offered this pair of teeth from Two Medicine--they are labelled as Albertosaurus juvenile, but, unless I'm mistaken, Alberto isn't from there? Could they be juvie Daspleto/Gorgosaurus, or are they raptor teeth? I am guessing it would be difficult with these to narrow it down beyond Tyrannosaur or raptor. I've got a pic of the bases if that helps. They are very small --- black one is 8mm, white one is 1cm. Black one is I think a premax tooth. One pic shows 3 teeth--but it's the middle black and the white one on the ri
  18. Hello. I was wondering if anyone could help me identify this tyrannosaur tooth I recently added to my collection. It is said to be from the Judith River formation in North-Central Montana. Unfortunately, I don't have the county it came from. The tooth has the following measurements. Thanks for your help. CH = 40 mm CWB = 10 mm CBL = 16 mm MC = 18 denticles/5 mm DC = 14 denticles/5 mm DSDI = 1.29
  19. I was out yesterday doing a final hunt before the snow sets in here in Montana on the Judith River formation and found this claw along with this vertebra, no other bones around so possibly from the same animal. I have found theropod claws that are much smaller and this one is huge when compared. I searched for the tip but sadly couldn't find it. I assume because of the size it would be a tyrannosauroid but not certain. Can it be determined to be a toe claw or hand claw? Is the vertebra identifiable? @patrickhudson

    Lance formation tooth question

    Hello, anyone able to help with this one? Going through my old "fossil" folder, I found this one I got 10 years ago bought as "Albertosaurus" from Lance Formation. Now, looking online I'm seeing Albertosaurus as not being from Lance. Indeed, only valid Tyrannosaur from there is looking like Rex Would this be better labelled as Undetermined Tyrannosaur, a T rex, or has Albertosaurus actually been found there? Apologies for pictures. The actual fossil is in storage box at my UK home, I'm in Taiwan and wont be going back there until COVID is over. S

    Tyrannosaur tooth ID

    I bought this tyrannosaur tooth a while back and it says it’s a albertosaurus, gorgosaurus, or daspletosaurus. Is there anyway to narrow it down any further? It says it was found in the Judith river formation of eastern Montana and it measures just over an inch. Any and all help is appreciated.

    Tyrannosaur teeth variations

    My son found a long skinny tyrannosaur tooth on South Saskatchewan River, West of Medicine Hat (oldman formation? Formost FM? DPP?) We've found all sorts of tyrannosaur teeth - short fat ones, short wide narrow ones, long fat ones, long narrow ones (Richadoestia), and all sorts of variations of curves or straight Species, age, and tooth position may all be factors. I'm just wondering if anyone has more info? This tooth is relatively narrow and thin for its length. I can post other examples of teeth found in the same area that are quit

    Bite mark on a tyrannosaur tooth?

    Hey guys, I found this tooth that has what looks to be fossilized with a slice from a bite. I'm not sure if that is what it is. Has anyone else ever seen this? It's a first for me.
  24. A response to Woodward et. al 2020's refutation of Nanotyrannus. Argues that specimens BMRP 2002.4.1 and BMRP 2006.4.4 fall outside the growth curve of Tyrannosaurus. https://advances.sciencemag.org/content/6/1/eaax6250/tab-e-letters

    Two Medicine Tyrannosaurs

    I'm hoping someone can provide a little information about tyrannosaurs of the Two Medicine. Somewhere I thought I picked up that Daspletosaurus and Gorgosaurus were the only ones found in Montana (with Albertosaurus being absent in MT). But now I'm not finding that, so I'm wondering if I just imagined it. Additionally, I keep seeing conflicting information as to when Daspletosaurus and Gorgosaurus lived (I'm seeing 83 Ma but other places 76 Ma with several other times around there). Can anyone share an article or two that describes the current understanding of when these animals lived?
