    • Is there a possibility of fossil inside these river 'mudballs'?
    • Cast this in black and I think it looks even better, it gets rid of the transparency so here you can see much more detail. I did mess it up a bit and the teeth on this one didn't turn out as good, even though I thought I had a good method down for doing them which involved carefully filling the cavity bottom up with latex with a hypodermic needle. Might be because I didn't stuff them with cotton like last time and they got damaged when taking out the cast, but I'm not 100% sure. Either way, I'm happy with the result and probably won't be making any more casts of this piece 
       
       
    • Thanks!
      I do actually use a mix of different materials.
      Thylacosmilus and Thylacoleo are actually altered versions of the commercially available Smilodon model from geoworld, as is my Megantereon and Inostrancevia.
      The skulls are 3d prints (Leo Nylon from a printing provider, the other ones PLA from my own printer). I used aluminum wire for additional ribs and lengthening of limbs, covered with epoxy putty.
      The images below show the process well, I think.
      Most of my models have 3d printed heads, the postcrania are a mix of plywood, wire, epoxy putty and, since I got my printer, printed PLA. all covered up with acryllic colours.
      Using the bought models saves a lot of time, some I only changed a bit, others are completely changed, like the Oviraptorid made from mixed parts, more and more are completely selfmade like Tanystropheus.
      Best regards,

    • Terrific @Misha! I have seen this specimen on here a few times and thought it would latex well, nice work
    • Made a latex cast of this fossil today. Still practicing the technique, so it didn't come out super pretty but it shows what the maxilla would've been like had it not been just an impression in the rock. Especially interesting is the teeth and how you can see that they actually curve inwards, which I didn't notice before. The latex also preserves the fine texture of the fossil cartilage, which I wasn't expecting, unfortunately due to the transparency of the cast you can't really see this in the photo. I want to try experimenting with coloring the latex or ammonium chloride later on to get better images, but so far I'm very satisfied with these results.
       
      This super cool technique was taught to me by @izak_ who seems to have it down to a science with some of his projects, as they look fantastic. 


    • Fantastic work!! What materials do you use to make these skeletons?
    • This one labeled G. contortus looks like Hemipristis.
    • Hey @bockryan,
      Is this guy enrolled?
