Resuming a consideration of mineralogy and dinosaurs
Topic: geology et al

I really shouild resume my reading in the book of mineralogy.  Some of this stuff doesnt't interest me much but I am determined to plow  through.  Sometimes a concept or two will strike a chord.  I wait for those moments

  I don't remember where I left off but I think it was with marcasite.  The next group is cobaltite.  It includes three minerals similar in appearance to pyrite.  They are cobaltite, gersdorffite, and ullmannite.  These are major ores of cobalt and nickel.  The composition is arsenic, antimony and sulfur.  


D inosaurs are more interesting I think.  I was just reading about a six inch coprolite found in Saskatchewan.  A coprolite is petrified feces from any species.  This one was supposed to come from a tyranosaurus and contained bone fragments which it was somehow surmised came from feeding on a juvenile herbivorous dinosaur about the size of a cow.  A picture accompanies the article.  And it looks about like you would expect it to look.
