QUESTIONS FOR THE DINOSAUR LIST:
1. The famous collection of Iguanodon in Belgium suffered
from "pyrite disease" - the oxidation of iron pyrite
("fool's gold" ) occupying bones as fossilization material.
The resultant iron sulphate caused the fossils to crumble.
The problem is apparently solved by use of ETHANOLAMINE
THIOGLYCOLATE. Does anyone have experience with this and
where is there a supplier?
I'd like to use it for the treatment of mineral specimens
suffering oxidation such as pyrite octahedrons.
Does it clean the surface of pyrite without etching?
2. My own collection of dinosaur bones (Drumheller, pre-Tyrrell) was
sprayed with clear acrylic some years ago (circa 1969) - same
stuff used by artists to protect their paintings. What's the
3. Does anyone know of *.GIF files of dinosaur specimens ? So far
I've located only silly cartoon characters or artists' sketches
or Jurassic Park props. Any good images from the Smithsonian
and other collections? I'm only interested in public domain
stuff that I can post on the BBS.
