  2. Indianapolis Children's Museum

    Hello, I was stopping through Indianapolis and gave their children's museum a try. It was surprisingly enjoyable! The museum covered topics from agriculture to racing to dinosaurs! These photos are from the dinosaur section. I followed the signs to the Dinosphere. I walked through the entrance and down the ramp. At the end of the ramp was a Sarcosuchus cast (no picture sorry). Following the path I emerged into a huge planetarium like structure filled with dinosaurs.

  5. Fossil Hunting Suggestions

    My father and I are planning on taking a trip fossil hunting this summer, we can't seem to find anywhere that really seems worth driving to. (Everything around us is basically Devonian.) We were looking for something different: Mosasaur, Arthropods (Cambrian preferred), Holocene, etc. My dad loves actual bones and I love arthropods from Cambrian. We came to a consensus and are looking for anything marine in the Mid-West. But we will take any suggestions into consideration! (We are new-ish to fossil hunting and are willing to go anywhere and do anything.
  6. Does anyone know where I could find a detailed Cedar Mountain Formation of Utah Map?
  7. Wear Facets On Rebbachisaurus teeth

    I've been reading a few papers on Sauropods and the topic of wear facets got me thinking. I own 30 plus Rebbachisaurus teeth and only two of them have labial wear facets. Every other tooth with a wear facet has a lingual wear facet. That doesn't really make any sense to me. For most sauropods with tooth to tooth contact, the upper teeth will have a lingual wear facet and the lower teeth will have labial. It could be that I just happen to own mostly upper teeth but I don't think so. Most every Rebbachisaurus tooth you see has a lingual wear facet. Any thoughts on that.
  8. Does anyone know of any good places in New Jersey where you can legally look for, dig, and take dinosaur fossils/footprints?
  9. Hey everyone! Last August I took a trip to Chicago and, of course, went to The Field Museum. It's quite impressive and absolutely worth visiting. All exhibitions I was able to see were awesome. My favorite part was the dinosaur room, though the most famous skeleton is in the main hall. Let's start with some pictures of Sue - the most complete T-Rexskeleton ever found. The skull mounted to the bod, isn't the actual skull found with the skeleton. The original skull is exhibited on the first floor and wasn't add to the body, because it was kinda squeezed (you can read all about it at the museum). There's also another bone section of Sue displayed on first floor, right next to the fossil lab, where you see paleontologists working (it's like staring at animals at the zoo, but very interesting haha). Scientists still try to figure out, how these bones match to Sue's skeleton. Close to the displayed shown above, is the entrence to the dinosaur room. While making your way to the hall, you're passing several exhibits, arranged in a timeline. To me themost interesting exhibt was the Dimetrodon skeleton. My first ever dinosaur book, contained a picture of it, so it wasawesome to see it in person after so many years. Once you entered the room, you see impressive exhibts of several herbivores. To your left you find a Stegosaurus: In the middle of the room is a huge Apatosaurus: On the opposite you have Triceratops: Sorry, forgot the name of this boy, eating a Edmontosaurus: Next to the shown exhibit, you can see a Parasaurolophus: AND there's also a juvenile Edmontosaurus:
  10. Hi everyone, I hope someone can help me. I am doing a school project ( fossil report) and struggling to find what i am looking for. I have never looked for fossils before and believe i may have missed what i was looking for today. I went out for a nice hike at horseshoe canyon in alberta. it was amazing, however i could not find any fossils. ( at least i think i didnt after looking at some pictures of this forum i may have and just missed them) I am a complete amateur. i did find a map on here for horseshoe canyon but still did not have much luck. i was hoping some one can help point me in the right direction. is there an area in the canyon that is best to look at? but most importantly what am i looking for? How do i know what is a fossil and what is well just rock. I feel silly asking but i am so intrigued and planning on making another trip out on friday. Thanks for any help you can provide.

  15. Its Spring. A glorious day. prairie Crocus are in bloom, the Meadowlarks are singing and the sky full of migrating waterfowl. First outing this year into the badlands. Headed out just north of Jenner, Alberta and then a trek east along the Red Deer River. Age is Campanian ( Late Cretaceous) about 72 million mya. All terrestrial deposits. A 6 km cycle ride in and then hike another couple. About 3 hours looking for fossils. Its feast or famine. Some hoodoos sterile and then an area dripping with vertebrate fossils. This area also yields a few 'unknowns' All fossils catch and release.
  16. Placement of terrestrial formations in the late cretaceous of North America as been constantly evolving and in October 2016 Denver Fowler a Paleontologist at the Museum of the Rockies published a very extensive paper on the subject and updated most units. This is very important when it comes to understanding dinosaur evolution and aids in describing species. This paper is in the process of going through peer review so is subject to change. Fowler DW. (2016) A new correlation of the Cretaceous formations of the Western Interior of the United States, I: Santonian-Maastrichtian formations and dinosaur biostratigraphy. PeerJ Preprints 4:e2554v1https://doi.org/10.7287/peerj.preprints.2554v1 The paper is pretty technical but all of the data is found in this excel file (supplemental information) which is a massive high-resolution stratigraphic chart for all of the formations from the late cretaceous of North America. It's nice to see it all laid out and a great reference source. https://doi.org/10.7287/peerj.preprints.2554v1/supp-1 To make it easy I've broken the chart apart so you can easily see most important dinosaur formations Texas The biggest change came with our understanding the Aguja and Javelina Formations of Texas part of the Tornillo group. The study indicated that the Aguja Formation deposits are only Campanian in age and that the Javelina Formation does not extend into the end of the Cretaceous. Very important when trying to describe species in those formations. Sellers have been comparing the Aguja to the Judith River in Montana well there is a correlation but its deposits are much younger that JR. Eastern Montana, N. Dakota, S. Dakota and Wyoming What I found interesting is that the Hell Creek is much older in Montana than in the adjacent states. The other interesting observation that can been easily be seen on these charts is that the how short a time frame the deposits of the Hell Creek/Lance formation are compared to the other major dinosaur formations. Central Montana Two Medicine and Judith River Formations are the two key formations in this locality Utah and New Mexico Utah depicted on the left and NM on the right Head North to Canada Alberta and Saskatchewan
  17. New Family Tree for Dinosaurs

    The family tree was announced back in February but the paper was just published. https://www.theguardian.com/science/2017/apr/19/how-we-revealed-a-new-family-tree-for-dinosaurs?CMP=share_btn_tw Abstract: For 130 years, dinosaurs have been divided into two distinct clades—Ornithischia and Saurischia. Here we present a hypothesis for the phylogenetic relationships of the major dinosaurian groups that challenges the current consensus concerning early dinosaur evolution and highlights problematic aspects of current cladistic definitions. Our study has found a sister-group relationship between Ornithischia and Theropoda (united in the new clade Ornithoscelida), with Sauropodomorpha and Herrerasauridae (as the redefined Saurischia) forming its monophyletic outgroup. This new tree topology requires redefinition and rediagnosis of Dinosauria and the subsidiary dinosaurian clades. In addition, it forces re-evaluations of early dinosaur cladogenesis and character evolution, suggests that hypercarnivory was acquired independently in herrerasaurids and theropods, and offers an explanation for many of the anatomical features previously regarded as notable convergences between theropods and early ornithischians Paper it's paywalls publication http://www.nature.com/nature/journal/v543/n7646/abs/nature21700.html

  19. Dinosaur Egg?

    Hello! Everyone has probably heard someone say here and there that they have found a dinosaur egg!! Although most eggs are very rare to find and you are very lucky if you do have the pleasure of finding one. I found this along with lots of other fossils in the same area. Just curious to know if you all think it is real or just a rock that is a look alike. This was found in Missouri in a small town of Fairdealing.
  20. This new analysis of dinosaurs and their near relatives, published today in the journal Nature, concludes that the ornithischians need to be grouped with the theropods, to the exclusion of the sauropodomorphs. It has long been known that birds (with their obviously ‘bird-like’ hips) evolved from theropod dinosaurs (with their lizard-like hips). However, the re-grouping of dinosaurs proposed in this study shows that both ornithischians AND theropods had the potential to evolve a bird-like hip arrangement- they just did so at different times in their history. http://www.nature.com/nature/journal/v543/n7646/full/nature21700.html http://www.nature.com/news/dinosaur-family-tree-poised-for-colossal-shake-up-1.21681 http://www.cam.ac.uk/research/news/new-study-shakes-the-roots-of-the-dinosaur-family-tree http://www.sciencemag.org/news/2017/03/t-rex-gets-new-home-shakeup-dino-family-tree
  21. Sexual dimorphism in Dinosaurs

    A paleontologist at the Canadian Museum of Nature is countering decades of studies that assert that some dinosaurs can be identified as male or female based on the shapes and sizes of their bones. A study was conducted on non-avian dinosaurs like Tyrannosaurus rex, Allosaurus fragilis, Stegoceras and Stegosaurus to determine if sexual dimorphism existed. The study included tests and concluded that no evidence for sexual dimorphism was found in any of the examined taxa, contrary to conventional wisdom. This is not to say that dinosaurs were not sexually dimorphic, only that the available evidence precludes its detection. So what are we to about the gender names given to T rex's and most other mounted dinosaurs Is Sue a He? Do we need gender neutral names http://nature.ca/en/about-us/museum-news/news/press-releases/male-female-canadian-museum-nature-scientist-challenges-evi Pretty technical paper recognizing_sexual_dimorphism_in_the_fossil_record_lessons_from_nonavian_dinosaurs.pdf
  22. I was looking at the latest news and this popped up which I thought was very cool that something like this exists "A group of paleontologists from the University of Queensland and James Cook University has documented the most diverse assemblage of dinosaur tracks in the world on the north-western coast of Western Australia." http://www.sci-news.com/paleontology/worlds-most-diverse-collection-dinosaur-footprints-04740.html The paper is part of SVP memoir series #16. Not sure if one can purchase this journal, it's pretty nice and if this interest you a hard bound copy is the way to go. Here are a few highlights Of the tracks examined, 150 could be identied and are assignable to a least eleven and possibly as many as 21 different track types: ve different types of theropod tracks, at least six types of sauropod tracks, four types of ornithopod tracks, and six types of thyreophoran tracks. Eleven of these track types can formally be assigned or compared to existing or new ichnotaxa, whereas the remaining ten represent morphotypes that, although distinct, are currently too poorly represented to confidently assign to existing or new ichnotaxa. Unfortunately the trackways are in a tidal area and will eventually disappear Here are some of the tracks found with descriptions
  23. Interesting new theroy. Major shake-up suggests dinosaurs may have 'UK origin' http://www.bbc.co.uk/news/science-environment-39305750
  24. Hey everyone! I want to know your favorite extinct animal and why. Theropods, ornithischians, artiodactyls, cetaceans, carnivores, plesiosaurs, pterosaurs, gastropods!!! Megatherium, Tyrannosaurus Rex, Anzu Wyliei, Leedsichthys, Stegosaurus, Megalodon, Glyptodon, Moonshot, Woodstock, Watergate, Punk Rock! (just kidding) ANYWAYS, there are no limits here. Even if its coral. Get specific! Do you have a fossil from your favorite creature? If not, is it even possible to acquire one? Have any interesting discoveries been made about your creature as of late? Just looking to learn and start some interesting discussions. GO! ------ Cheers! Lauren
