Hi everybody!
I must make a dino skeleton , that can be buried in earth (it must stand humidity). I confess it is NOT a puppet, but it is so close to the subject, that I thought I may get help here  , regarding material to build it. I can sculpt, but not sure what material to use here. It must not be expensive, though. Thinkin of making it with paper, and then cover the surface with some hardening product? If anyone knows what product can I use, please give me a hint. Or any other idea to make the skeleton, very much welcome. Thanks!!

Hi Titere,

I'm not an expert in the field, but what about resin? How big will it be once complete?

thanks!

How long must it be in the earth?  If it is just for a short period of time then I think you could get away with using paper mache' that you then seal with lacquer or a really good outdoor house paint. Wood might also be a media choice that is then sealed with outdoor house paint.

If it has to be in the ground for a really long time then I think you need to make it out of something like resin or perhaps fiber glass.  The problem with both of those, is that it could get expensive. Plaster of Paris or concrete can be used out doors if you seal it. You can normally find sealers for both at hardware stores.

Thanks Animal and Shawn! Good advices, ill try a lacquer sealer.
