  1. I'm 3D printing this Velociraptor's skull - https://www.thingiverse.com/thing:2736627 Details are very realistic, but I didn't found any real Raptor's skull image to compare. Internet is full of replicas... Anyway, if you're going to 3D print it, consider that it is a very pain. It is badly split, and it is not very easy to 3D print: more than half of the pegs will break and some of the pieces have mesh issues. Also, I suggest to print teeth flat on the 3D printing bed, and not as the original STL. I will update the post with new images as I glue and paint it. Regards, Adriano
  2. Sigilmassasaurus vertebra

    Fourth cervical vertebra of a Spinosaurid. Very likely Sigilmassasaurus due to the short dorsal spine and proportions of the postzygapophyses.
  3. Hi everyone! As I have mentioned several times, being a 3D artist I am trying to move into the field of paleoart. Recently I have started modeling Ceratosaurus nasicornis in 3D, and I really want to make it as accurate and plausible as possible. Here is what I have got so far: a basic model done in 3ds Max. After this I am planning to take it to ZBrush and add more muscle definition, sking wrinkles, scales and other fine details. At this stage this is just the base and I would like to share it with you guys in order to receive some feedback from those who know their dinosaur anatomy. Did I get the shape and overall structure right? Constructive criticism is more then welcome, pretty much this is what I am asking for here. 1. Mesh 2. Body 3. Perspective 4. Back 5. Top view 6. Head close-up
  4. Hello everybody, This is my first post and first piece of artwork I would like to share and, hopefully, receive some feedback. I do 3D animation and rendering for living, but paleontology is my life long interest and passion. Here is my 3D reconstruction of Cambrian trilobite Olenoides serratus that was a common member of the famous Burgess Shale biota. I actually live just 250 km apart from the famous Burgess Shale quarry (and 100 km from Albertan Red Deer badlands rich with dinosaur fosslis).
  5. Bumpy Nodules

    Two halves of the same nodule.
  6. Hi everyone. I'm a 3D artist and freelancer with lots of interests in paleontology. And for 6 years I have made dozens of models, many of which are of prehistoric model. I always try to make the model as accurate as possible. Here is a small figurine of the Psittacosaurus , with it's skin flaps and beak and coloration and everything (with the exception of the quills, due to 3D printing restriction). Besides this model, here are more pictures.
  7. classic,IMHO

    inEWESTcephalopsuturesrep89.pdf I loved fig.5,the reconstruction. Pictorially stunning If you already have the classic Westermann ,Oloriz,Hewitt and Checa literature: this is right up there,and then some But do I recommend it? on Doush's PDF-grade-o-meter*: 11 out of 10 *patent pending
  8. 3D printed skull

    Hey guys and gals, I believe some time back I saw a forum member that was doing 3D printing of skulls. Anyone remember seeing this? my searches were fruitless. I would be very grateful if someone could point me in the right direction. I am looking for about a 1/4 scale model of an Allosaurus skull to place in a donation box so customers can "Feed the Dino"
  9. Not sure if this is old news or not but it's a pretty good resource I only recently discovered... https://www.youtube.com/watch?v=b3eWcjXxVns https://umorf.ummp.lsa.umich.edu/wp/ Darrow
  10. Archeoceti skulls 3d WIP

    Hello again, on my constant search for 3d archeoceti references I stumbled upon a method that seems very promising: I took a 3d scan of a dog skull that I scanned myself via photogrammetry and twisted it around until it looked more or less dorudontine to me. That´s much less work than building the dorudon-skull from primitive shapes. Took me about 3 hours so far. This Method seems nearly unlimited to me (for artistic uses anyway) Take the closest recent skull you can get and transform it into your species of choice. I have never done anything like that before (not digitally at least) and after one day trying around Iam astonished at the result. Archeoceti here I come! here is the 2d reference I used: https://de.wikipedia.org/wiki/Datei:Dorudon_atrox_and_Maiacetus_inuus.jpg I hope for contructive advice on what is still wrong with the skull. Does it have to look so evil from the front? that´s what came out when I tried to recreate the top- and side view. Best Regards, J J
  11. Sigilmassasaurus vertebra

    Vertebral process of Sigilmassasaurus. This is likely a mid cervical vertebra. It also bears close resemblance to the Spinosaurus maroccanus holotype which I consider to be synonymous with Sigilmassasaurus brevicollis.
  12. Dinosaur Vertebra

    Anterior dorsal? vertebra of a dinosaur. Likely Theropod due to it being hollow.
  13. Tyrannosaurid tooth

    Tooth of a Tyrannosaurid. This tooth belongs to either Albertosaurus, Gorgosaurus or Daspletosaurus. Note the wear facets on the top and medial side of the tooth.
  14. At the very beginning of the 1960s, a South African palaeontologist embarked on a series of ambitious works. Dr A.S. Brink wanted to better understand the anatomy and evolution of humans’ pre-mammalian ancestors, the therapsids. Brink worked with therapsid skulls found in South Africa’s Karoo region. He ground the skulls at thin and regular intervals to assess their internal cranial anatomy. The technique, known as serial grinding, was commonly used at the time. As he neared the end of the process on one of the skulls Brink realised that he had uncovered a unique specimen. The skull represented a holotype, which is the single specimen used in the definition of any new species. But by then it was too late. More than 50 years later, we were among a group of scientists who followed in Brink’s footsteps. Our task was to recreate this unique specimen. Technology has moved on enormously in the last half century, so we were able to use 3D renderings and 3D printing – and one of our mammalian ancestors was reborn. Historical techniques South Africa was a good place for Brink’s work. The country’s Karoo region is home to a wealth of therapsid fossils, making it an important place to study the ancestry of mammals. Brink was not the first palaeontologist to use serial grinding. The technique emerged at the beginning of the 20th century. Before then scholars had to wait for the discovery of naturally preserved casts of internal structures, like the mold of the “fossil brain” of the Taung Child, Australopithecus africanus. Or they had to break fossils open. With its introduction, serial grinding became the only fully controlled way to access the “interior” of fossils. Because of their abundance, South African therapsids were among the first fossils to be studied using this new, revolutionary approach. Sadly, their abundance turned out to be a curse. Accidental destruction In 1961, Dr Brink started the serial grinding study of a well preserved skull. At this stage, he thought the specimen belonged to a common form of therapsid. But during the process, the sections revealed anatomical structures that suggested the specimen may actually represent a new species of fossil therapsid previously unknown to science. By then it was too late to save the fossil: it had already been mostly ground down. Brink tried to compensate by making a very thorough and accurate description and drawings of the specimen. He named it Scalopocynodon gracilis. As in zoology, the designation of type specimens is the most critical step when naming a new species in palaeontology. This type specimen, called a holotype, is meant to serve as an anatomical reference for future comparative works. A new species can’t be recorded without a holotype. So this ground specimen was particularly important: it constituted the holotype of Scalopocynodon gracilis. Sadly this valuable and irreplaceable piece of South Africa’s heritage and evidence of the evolution of pre-mammalian therapsids was lost. The irony is that it was destroyed by the very author of the species. Scalopocynodon was considered dead and forgotten – until 2016. Recreating our ancestor in 3D Evolutionary Studies Institute, Wits University It’s then that a team from the Evolutionary Studies Institute at Johannesburg’s University of the Witwatersrand retrieved some of Dr Brink’s drawings of the Scalopocynodon gracilisfrom 1961. These drawings represent each thin section ground by Brink. Their detail presented us with an unprecedented opportunity to virtually reconstruct the long lost specimen of Scalopocynodon gracilis. The drawings were digitised. Then, using cutting edge software and innovative computer-based technology, every slice was digitally reassembled in a single stack. This allowed us to reconstruct a 3D model of the original skull. Afterwards a physical model ofScalopocynodon was printed in 3D so we could recreate a life-sized reconstruction of this specimen. To our knowledge, this is the first time 3D technology has been used to recreate and print in 3D a serially ground fossil vertebrate (though it is quite often used in invertebrates palaeontology). This is a great initiative for South African heritage conservation. These techniques can be used on other fossils lost through serial grinding. Breathing new life Recreating a fossil using 3D technology is painstaking work. The 3D printed skull, serving as a holotype, could also help to breathe new life into this mysterious specimen. Taxonomists can now study it and one day might be able to say definitively that Brink was right: Scalopocynodon gracilis was indeed different from any other therapsid. http://theconversation.com/3d-technology-brings-a-lost-mammalian-ancestor-back-to-life-64059
