I was in Milwaukee for a concert last weekend and I decided that I should revisit the local natural history museum while I was there. The Milwaukee Public Museum was a childhood favorite of mine- it honestly left a stronger impression on me than the Field Museum, and there is one main reason for that: their incredible life-size reconstructions of prehistoric life. So that is where my focus for this report will be. The fossils on display were mostly casts, and nothing stood out to me as particularly notable. Near the entrance, the museum had a diorama showing paleontologists at work, along with some featherless dromaeosaurs. Nearby, though, they had a reconstruction of one with some plumage on: The first ancient ecosystem you encounter when entering the hall of prehistoric life is the Silurian seas that covered the area. This is an incredible display, teeming with trilobites, crinoids, brachiopods and the enormous orthoconic cephalopods. Up next is a small display of tetrapod evolution- this one spans multiple periods, featuring Ichthyostega in the water and Seymouria on the land. Across from this was the Pennsylvanian coal swamp display case. This one unfortunately was very slightly run-down, with some animals from the accompanying identification key missing. But I still greatly appreciate the detail and care that must have gone into creating it. I especially like the attention to detail in the display, and the inclusion of some smaller animals like the coelacanths in the water. I have to pause here, but I will return with my dramatic and enduring core memory of the museum later, the Mesozoic display!

A reconstruction of the biotope of Sansan (Miocene, Gers, France)
archeo posted a topic in Paleo Re-creations
I begin the reconstruction of the biotope of Sansan in France (Gers). https://books.google.com.sv/books?id=7s8yAQAAMAAJ&printsec=frontcover&hl=fr&source=gbs_ge_summary_r&cad=0#v=onepage&q&f=false https://sciencepress.mnhn.fr/fr/collections/memoires-du-museum-national-d-histoire-naturelle/la-faune-miocene-de-sansan-et-son-environnement https://sciencepress.mnhn.fr/fr/collections/memoires-du-museum-national-d-histoire-naturelle/mammiferes-de-sansan https://www.mnhn.fr/fr/paleosite-de-sansan. -
I am new to the forum and I am presenting ideas that I have been thinking about in relation to dinosaurs and dinosaur fossils. One idea that intrigues me is the idea of fossil DNA. I don't mean physical nucleotides that might be found in or around dinosaur fossils. I mean ancient DNA or RNA sequences that might be preserved in the "non-coding" DNA of the dinosaur descendants, birds. DNA and RNA are basically scripting languages for building and activating proteins. When we think of evolution, we mostly think in terms of the evolution of organisms. But there is a meta-evolution of DNA and RNA themselves. Among the other things I do, I write encryption and decryption programs. These are ways to hide and reveal meaningful sequences of information, for later use. It would make sense to me that mutations, particularly successful ones, should be preserved in the DNA record. Obviously they are, in evolutionary successful organisms. But what about when a new mutation appears and replaces an existing gene or set of genes Why not transmute the no-longer-used coding genes and epigenes and store them, within a set of markers, in the noncoding section of the DNA. Perhaps under certain environmental stresses, such as scarce food or overabundant food, the organism responds with mutation activation process that both create random new DNA sequences, as well as reactivating previously successful ones to try them out in the current environment. Perhaps inside every ostrich, the fossil genes for one or many species of dinosaur lie waiting to be revealed. While this might seem like a hint at intelligent design, languages can capture random changes and make them part of the structure over time. A good example of this is the aging of most animals. The process of the individual organism developing senescence was incorporated into our gene line many millions of years ago. The environmental advantage for it is that it allows younger organisms to compete successfully with older organisms, which allows more rapid evolution. From the point of view of the individual organism, aging is an always deadly genetic disease. Without this programmed process, we might live extremely long lives. Molecules do not get tired, and chemicals do not run out of steam. In this view, every organism is a GMO. The process of evolution is enhanced and accelerated by as yet unknown genetically-driven designs. Evolution is not a completely random process. If this encoding exists it should show up with some investigation. I am sure the first billion years were the hardest. -Brad Jensen

I just wanted to share this, thought it might be of interest and there's definitely room for improvement and tips! This was the first fossil mammoth tusk I restored and prepared a few years ago- a juvenile mammoth tusk that was split laterally almost perfectly down the middle. It was sourced from central Alaska, though not sure if it was discovered in a mining operation or if it was exposed on a river bank as so many are. The first step was to submerge and soak the entire tusk in a PVA solution, followed by Apoxie sculpt and banding to merge the two broken pieces and restore some of the tip. I haven't ever done this before so I used the grey Apoxie, in retrospect maybe the white color would have been easier for later coloring? Maybe mixing color in the Apoxie pre-hardening? After banding and curing, the two pieces held together and it was time to sand sand sand down to I think 2000gr. Lastly, I colored the Apoxie fill with various wood stain colors, however I wasn't a huge fan of that- does anyone have any recommendations on how to do that better? I've never been a painter and know nothing about what to use or color matching, but would love some info! I've done other projects and thought about taking on restoration projects where this knowledge would be really helpful but admittedly I'm really inexperienced with coloring any sort of anything. I've seen people reconstruct 1/3 of a cave bear skull and it's like you'd never know unless you were really looking for it. I have no idea how they do that! I'm sure that takes some serious artistic talent that I don't posses, but any tips for this would be appreciated. Originally I built a stand out of bent/polished brass and a block of wood I got from a trophy store that is somehow still in business in this little Alaska town. A couple years after I made the original stand I decided to make a new stand out of a small petrified wood slab/slice. I really like the look of it better (though I'm not crazy about the brass anymore), but I had a really hard time drilling the holes in the slab- I broke a few bits before I bought some stone/tile bits, and even those weren't great! I was only able to drill the holes just barely deep enough to hold the brass wire. Any tips on drilling petrified wood?? I have a few other small things and potentially a few larger items that would look killer on a similar stand. I've done a few tusks since this one, none of them with such significant damage, though none are complete tusks I think I'll post another one of the interesting ones that has amazing vivianite and what I think are actual cobalt crystals in the internal cavity. The restoration done on this tusk is only for me, I have no plans on selling this so in looking for reconstruction/restoration tips & tricks, it's purely for my own collection and enjoyment- not to try and fool some unwitting buyer on our favorite auction website! To be honest, the preparation is the most fun for me! Enjoy! Nick

Reconstructive skeletal drawing- perspective foreshortening
Mahnmut posted a topic in General Fossil Discussion
Hello dear fellow forum members, I need some advice. Until now, I have built my models mostly trying to follow the reconstructions others have made, often in form of profile-view skeletal drawings. At the moment I am trying to build a model of Helveticosaurus, which is known from a rather complete, but heavily crushed skeleton. The one Skeletal reconstruction I can find online comes from a source that I do not trust (the one calling itself heretic), so I try to start from the fossil. In that online drawing, the lumbar ribs are showing a strong curvature of about 90 degrees, which is definitely there in the fossil. But I do not believe that all of this curvature would have been visible in the lateral view. Below is my take starting from Kuhn-Schnyders drawing of the fossil itself: http://www.thefossilforum.com/uploads/monthly_2021_03/54696752_HelveticosaurusafterKuhn-Schnyder1974.jpg.ce995add17ae5d89b765a7ca17a337a9.jpg Concerning the reconstruction of Spinosaurus it has been discussed intensely if it is legitimate to show the leg bones as perspecive- foreshortened, or if they should be shown in their full length as if lying flat on the paper. Concerning ribs my impression was that skeletal drawings usually show what the anatomically connected ribcage would have looked like from the side. Any advice would be much appreciated. Best regards, J

Six years ago I got the chance to visit the Walcott Quarry (see my longer post on this adventure in fossil trips) and while there I found this specimen of Vauxia gracilenta. Ever since I've wanted to make it part of my collection somehow, so this year for my birthday I decided to have a life reconstruction commissioned. Having seen the other fantastically detailed Cambrian models produced by @thorst, I asked him if he would be willing to reconstruct and 3D print the sponge. I drew an interpretation of the fossil and in no time he had it completed. A huge thank you for helping me make this possible. The level of detail in the model is incredible and you can clearly tell side by side that It's the same Vauxia that I found back in 2015. As soon a I have a proper fossil shelf it will have pride of place. Benton

My preferred medium of artistic representation, origami. Can you guess the animal it’s going to become? Here is the base (the initial form) and a picture a little further on with the legs of a Cretaceous creature I’ve started folding from a 24cm square of paper. The model design for this one isn’t mine, but I have designed a model before and hopefully will make some more of my own in the future. Hopefully the finished model will grace my shelf when I finally find one of these in fossil form. I hope you all enjoy, Benton

Back to recreation. This one doesn´t fit any of my other threads, so here I go. As I recognised that I already built or modified models of many of the existing orders of mammals I started to look which ones where still missing. I got: Metatheria: Thylacoleo Xenarthra: Thalassocnus, Tamandua, Glyptodon Afrotheria: Hydrodamalis, but no Proboscidean yet. Laurasiatheria: (Cet-)Artiodactylia: Syndioceras and loads of whales Carnivora: Odobenus Perissodactylia, Chiroptera and insectvora are still missing,as are some others. rodents: Ceratogaulus is on the way to the printer Primate coming now: Megaladapis, one of the giant lemurs of Madagaskar. I could not find good pictures of the bones, only several perspectivically distorted fotos of the same two mounted skeletons (on in a somewhat strange quadrupedal stance and one really nice upright one tha nonetheless doesn´t show every bone I need. So if you know where to find good images of this guy or gal, I´d apreciate it. For now I got this far:

I'm posting a current project in the hopes that it actually makes me finish it. I have a tendency to start several projects and set them aside for years. This Lepticitis was found in Wyoming in the late 90's. The initial prep was done by someone else (unknown) before the specimen made it to my collection. I've spent the last 5-6 hours under a scope removing glue, I would have almost surmised it was dipped in penetrant. It appears to have some abrasion damage as well, see the dorsal view of the skull above the orbits. I also took the opportunity to clean out foramen and do other various cleaning with pins and needles to get it to the state it is in now. Wish I'd though to get a pic before I started. Thanks to @jpc, I have some excellent photos of another Leptictis to base reconstruction off of. I'll post some more photos as the work progresses.

UPDATE 3/9/19 - Basilosaurus reconstruction/repair/restoration - DIY
fossilized6s posted a topic in Fossil Preparation
I purchased a unsightly Franken-Basilosaurus tooth a few weeks ago for pretty cheap. Seeing as though i don't have $400-700+ to spend on a nice basilosaurus tooth i saw potential and a fun project in this cheap ugly duckling. Yes, it's Moroccan. It came with the typical glue/sand mix covering it, filling all cracks, voids and roughing out transitions of deceptive franken composites. How it came: Ok, first things first. Clean it. I used acetone, a razor, a needle, a tooth brush and my engraver. Hours of delicate work later i finally see what i'm working with. After cleaning: Yeesh, this might be more work than i thought...... And someone composited a incisor or canine tooth tip on the top of my premolar!! Bwahahaha!! Ok, composites need to go. Bye, bye Next i noticed this was not lined up correctly when it was glued back together. So i grab my trusty dremel tool and proceed to carefully saw this baby in half. Then i removed most of the epoxy/sand glue from each side. Continued.........

Good morning. I live in Oregon and I am looking for people that can “Professionally” do fossil preparation and restoration. I have specimens that are still in their field jackets. I have some specimens that just need some touch up. I have contacts in other states that are more than qualified that I have used in the past. But it always makes me nervous shipping specimens anywhere to be honest. I have had femurs that were packaged extremely well and still showed up snapped in half. Or on the smaller boxes for like teeth or claws end up missing. To say the least, it’s very frustrating and nerve racking! So what I’m looking for is someone local that will do top end work. And I would prefer someone that will have references or even people on here that can back their abilities up from personal experience. I 100% understand that when you want top quality, you’re going to pay a price for that and that’s ok. I also understand that quality takes time to achieve. So just to be clear, I’m not one of those guys that’s going to drop off the specimen on Monday, and then call you on Friday and ask if it’s done yet. It gets done when it gets done. Obviously If we get to the sixth month mark, I’ll probably reach out to you to make sure everything is fine. So now for keeping the admins happy. I think you need to PM me your information and not publicly post it because they don’t want to have people doing any business advertising If I understand them correctly. But please feel free to publicly post that you are sending your information my way and that way If anyone on here has used your services, they can speak up. I think that part is okay per the admin. I’m sure they will let us know shortly if I was wrong. Thank you everyone ahead of time. Sincerely, J

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

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).

So I drew a paleo-reconstruction of a noteworthy but sparsely-known apex predator Temnodontosaurus eurycephalus, which was believed to be the top apex of the Early Jurassic until the rise of proto-pliosaurs like Rhomaelosaurus. Unlike its famous squid sucking sister T. platydon (metaphor, not literally), T. eurycephalus had a thick skull with deep jaws and large robust teeth suggesting a macropredatory diet and probably fed on other ichthyosaurs, plesiosaurs, and anything else that it could swallow (Also, growing lengths of over 30 feet, it probably could swallow everything other than another Temnodontosaurus) This is actually my first time finishing a paleo-reconstruction using only a pen tablet and photoshop (All my other drawings were either unfinished or done on paper). I used a Huion 1060PLUS drawing tablet and Photoshop CS6 to draw this. Took at least 3 hours to draw, and I heavily referenced the holotype skull to draw the head. Turned out pretty neat, but I don't know if I should color/shade this.

soo, im currently trying to reconstruct some pleistocene fauna (mainly felines for now) and i have almost no problem with anatomy, muscles and such, but i do have a problem recreating the fur color, pattern and length. im currently working on the smilodon populator, and i really have no idea what to paint it, in one side, it was a south american cat, all modern cats that distribute the area are spotted and yellowish colored (ocelot, jaguar). but on the other side, it lived in the savannah, which "allows" all kind of fur patterns (plain/lion, spotted/leopard, etc). and it was a realtive of smilodon fatalis, which lived in north america. there are no remains of fur and no cave drawings of smilodon from what i have found, so if anyone knows any articles which comes up with speculations about this kind of stuff please link them here, im also having a hard time founding pictures of animal skeletons in a neutral pose (standing still) so if there is a collection of these kind of images i'd love to know about it thank you very much and sorry for bad english. i'm not sure if ive put the thread on the right forum so let me know if i made a mistake.

New guy from Chicago. Biochemist by day; trilobite enthusiast, artist, and student by night. I'm here for the wisdom and enthusiasm for biology evident on the boards. Hope folks enjoy what I make with what I've learned here, and maybe even get inspired to learn more about prehistory because of it. Here's a work in progress. See you on the boards...
