    Acrocanthosaurus Teeth

    A good number of Dinosaur collectors, on this Forum, have Acrocanthosaurus on their wish list and its one of the holy grail of teeth to acquire. I saw this post by Jim Kirkland and thought I would increase the drool factor. He does not state what formation it came from but have to believe its the Cedar Mountain Formation.. Enjoy His comment "Acrocanthosaurus serrations are so fine you can barely see them"
  2. I found this in Southeastern Oklahoma. I found it at a lake. It was showing due to the water levels being down. I've contacted someone down in Keene, TX about it and they said there is a possibility one or both are acrocanthosaurus tracks or trace tracks. They have found tracks up in Atoka County. Which is 45 minutes away. There are tracks, also,also, a museum in Idabel, OK. Then, if you head south, there's dinosaur valley state park. Where you can view tracks in the river. I explained, to the person who specializes in this stuff, I moved it, but took documentation of where I found it. So the water could no longer erode it. There is a museum close. It is about to start their Dino Days again. I really want to go get it checked out. I've cleaned the piece up since I brought it home last year. But I'm afraid I will do damage. I want to clean it, but not destroy it. We have some ammonites we have been cleaning. Those seem a lot easier than what is going on with the possible track. The light colored rock, is another possible track found near the other one. Facing a different direction. This one I could not move. Is this my mind just playing tricks? Or did I possible find something? Either way, it has been a fun experience and practice, for me.

    Acrocanthosaurus?

    I've got a rarity to try and confirm today, folks. The seller says it's an Acrocanthosaurus tooth. It is from the Cedar Mountain fm. (if I remember correctly, tooth morphology has not been described from this formation) in Grand County, Utah. The serration density per 5mm is about 17 on the mesial side and about 15 on the distal side. Due to its possible rarity, I understand that I may have to provide more information about the tooth, so let me know if there is additional specifications needed.
  4. I had a pretty great birthday 11/09! Still young at 31! Cole woke me up the night before and said after work he is taking me out to Glen Rose Dino Valley State park in Glen Rose, TX and then going ammonite hunting for some decorations for Ruby’s vivarium. (Ruby is my pink morph western hognose snake) Of course I couldn’t go back to sleep before work after that! I know a lot of Texans probably went there during grade school and to some people dinosaurs are too “typical” but for someone who has lived in Indiana & Texas where it’s mostly marine fossils (and in Iceland there were pretty much none!) this was something new and exotic to me, albeit trace fossils. I worked my night shift super daydreamy and stargazy knowing it was going to be a fun day later on, clocked out, and we immediately drove out there! About good 2 hours away where I live and I couldn’t sleep on the way out there. When we finally got there they tried to charge me a child/teen ticket! The park ranger lady thought I was Cole’s teenage daughter. I immediately corrected the ranger and showed her my ID to prove I was 31 to charge me the correct amount (because thats the right thing to do!) and she gasped in shock, complimented my youth and my handmade ammonite earrings, gave me some free goodies along with a map. I haven’t eaten or slept in over a day and honestly it didn’t matter! I was so energetic and excited to be here I didn’t feel any fatigue at all! ^ If ya’ll don’t have the Rockd app- do so! So nifty especially when exploring a new place. We went to all the places on the map that had tracks, I waded in the water of course to see them up close! It was an incredible new intimacy with nature seeing them in person. You hear about them and think “yeah that sounds cool” but your eyes inches from them is whole other experience. The first one I spotted was an Acrocanthosaurus! I crawled immediately down the trail into the Paluxy river and splashed right into the water. After waiting a few minutes for the water to clear I was awarded with this: I reached down and touched it extremely delicately and it sent a jolt of adrenaline through my body like electricity I can’t describe! I got goosebumps like CRAZY. Cole knew I was having one of my “connection with nature moments” and watched me from the dry trail since he is hydrophobic as heck and didn’t want to join in. I’m the total opposite and if there’s enough water at a site- I go wading or swimming even in Texas! I just went on without him in the water and he followed me using the trail. Luckily he had my fanny pack but my phone is waterproof and stayed with me so I could take pictures. Roped off area: I want to share some odd prints I found that I dont think were marked on the map between Wildcat Hallow and the track site by the camping area. I don’t know if the map just needs updated or they are meant to be a “surprise” for the curious explorers but either way I’m sure the rangers know about them and it was fun to see them. Sorry for the finger and shoe marks, I actually tripped in one because I didn't expect any and wasn’t paying attention. (I was spying for any scaley babies at the river bank! Lots of turtles out that day, unfortunately I didn't spot any snakes.) I tried not to directly touch the dry prints. Hoooooly spit. My favorite part is “the ballroom site” where there are HUNDREDS of tracks! Lots of sauropod and predators prints here, the metatarsal tracks of the Acro were ADORABLE. Its amazing how if you look at a set and follow them you can imagine the walking behavior of the animal where they started walking and picking up speed to a sprint. SO. CUTE. My favorite prints were the rear- leg footprints of Sauroposeidon! You can just tell that it stood in thick, firm limy mud the way it was preserved and you can just “feel” it was a hefty animal by the look of the prints. I yelled out loud in awe it was so neat! (There were also just too many tracks to photograph) There were some lines in-between the series of sauropod tracks I was curious if that was the tip-end of its tail that may have left them? map of this track site: Blue is sauropod tracks; red is theropod tracks After this I went over to the deeper water by the swimming hole threw my boots & socks off and just dove right in with my clothes on. (We had pretty much that whole area of the park to ourselves and I brought extra pants & socks anyways!) It felt SO refreshing. I just relaxed enjoying the gorgeous weather ignoring Cole yelling at me (barely audible) worried about brain eating amoeba and wet car seat towels. (He shouldn’t be surprised being my best friend for 13 years now ) Sorry but the water was just… calling me! I was swimming over 100+mya dinosaur tracks and I felt so comfortable in my element. It felt so “right” and I was in full serotonin overload. Exhilarating! The only other fossil I saw besides oysters and dino tracks: Gift shop because I’m such a tourist in my own State. xD I can’t resist a signed book about paleontology! I have yet to read it as of this post but I know it’s about the history of the park and it came with a “dinosaur ballroom dance” CD. We went to Brookshires and then rewarded Cole with the biggest bag of jerky I could find, caffine, paid for a full tank of gas, and said thank you a billion times. This place was worth the visit no matter your age! The nature and hiking trail options itself are enough to visit if you like outdoors. *I have pictures and a few vids on my IG paleopastels as well! After spending most of the entire daylight there so I could dry off we went to my favorite spot in the Goodland Form and plucked out a few fast things on the way back home! I love the Oxytropidoceras the most Cole found me (Yay! So proud!) and I was happy to add another Heteraster to my shelf. I left the Pliotoxasters alone since I have a handful of them from last time. I got a few nice pieces of snake rocks to take home as well. Wet pants, dont care. What’s exciting is my zoic air pen from the UK + a few unique Dactylioceras fossils are coming in the mail soon! A little present to myself. What a great day! That day was the BEST present and best birthday to date! Hopefully this report helps others planning a visit to there! Thanks for reading!

    Acrocanthosaurus tooth

    From the album: Dinosaurs

    Not mine - belongs to a university. I want to say it is about 3 inches in length. I cannot remember exactly where it was found, but I do know it was an isolated tooth found in Texas. Quite a rare and awesome tooth to see in person.
  6. I know that Acro stuff is quite rare and hard to come by, but I was wondering what the best spots in Texas are to find such fossil material. I live in the state, so it would not be too much of an issue to travel to a spot or two to hunt for these theropod fossils. To sum it up, my question is: what are the best spots in Texas to legally hunt for and collect Acrocanthosaurus fossils/teeth (preferably without heavy duty tools or machinery)? If there are any, it would be much appreciated if you list the formation and location.

    Dinosaur Tracks

    Thought I would share some of my Acrocanthosaurus tracks in my collection from Texas. These are from the Glen Rose Formation. Anyone who has dino tracks, please feel free to post them here on this thread too...would love to see them! The associated pair are big...both over 20 inches long.

    Glen Rose theropod track (2)

    From the album: Dinosaurs

    I took this photo a while back in Dinosaur Valley State Park. Texas was in the midst of a drought, so the river that usually flows over the trackway was dry. I wish I had taken more photos (with a better camera too). These 3-toed theropod tracks are from the Early Cretaceous, and were likely made by Acrocanthosaurus.

  10. Made it to the second week 2020 whoopeee lets celebrate with some cool photos of extraordinary fossils. If you have a photo to contribute please do so. Skull of Duriavenator hesperis, a Middle Jurassic theropod dinosaur from England. Torvosaurus tooth from the Upper Jurassic of Portugal, Lourinha Formation. 15 cm in length is one of the largest theropod teeth known on the Upper Jurassic fossil record by Elisabete Malafaia This is the holotype of the hadrosauroid "Orthomerus dolloi" from The Netherlands. Courtesy of Susie Maidment Macroelongatoolithus clutch from South Korea. Maybe Gigantoraptor-sized oviraptors laid these big elongated eggs. 61 cm eggs have been published from this site. A gryposaurus notabilis skull at Museum of Nature. Loving the big honking nose on this duck-billed, Erika Anderson Tom Cullen shows us some Ornithomimid dinosaur skulls at the ROM Jaw of Acrocanthosaurus from Texas Holotype of Nanotyrannus lancensis at Cleveland Museum Photos of USNM 4928, on display the CU Museum of Natural History, Boulder. This is the holotype for Triceratops calicornis, and was collected by J.B. Hatcher in the Lance Formation of Niobrara County, Wyoming in 1888 Nanotyrannus Skull of the Dueling Dinosaurs in Montana
  11. Hadrosaur carcasses must have been great hiding places for fishes during the Cretaceous. A beautifully preserved primitive sturgeon, in the belly cavity of a Brachylophosaurus skeleton. Thanks Jack Horner Here’s the holotype skull of Gorgosaurus libratus. This specimen was collected by Charles Sternberg from Dino Prov Park, Alberta & described by Lawrence Lambe, Canada’s first vertebrate palaeontolgist. Thanks Dave Evans Thigh bone and shin bone of a subadult Triceratops. The thigh is much longer than the shin making for a relatively short stride, suggesting Triceratops was very slow. T. rex was definitely faster than a trike & probably didn’t need to run to catch one. Compliments of Dave Evans. Wonderful skull of the very early dinosaur Eoraptor from the PVSJ collection in San Juan. It’s from the early Late Triassic Ischigualasto Formation. NHM Dinolab The theropod Coelophysis baur the State Fossil of New Mexico. This mass death assemblage depicts multiple individuals who died at the same time. Thanks Guy Leahy. Here’s a nice big T. rex tooth from Saskatchewan. Not the prettiest but from a cool location. D. Evans Acrocanthosaurus mount completed by the Black Hills Institute. Heading to the Netherlands Something you dont see often jaws of Iguanacolossus fortis. Its a genus of iguanodontian ornithopod dinosaur that lived in North America during the Early Cretaceous period from Utah . Jim Kirkland Dinossur material from Austria wow.... you are looking at the nodosaur Struthiosaurus austriacus, from the Campanian of eastern Austria. Represented by multiple individuals of different growth stages, here is the braincase and two spikes. Tom Raven
