There is a very good site which has endlessly fascinating articles about dinosaurs, and other items of scientific interest.  If you are a rockhound you have probably accessed Bob's Rock Shop.  Don't neglect the article section. 

 Today I was reading about Gigantoraptor, a bird-like creature that stood sixteen feeet tall.  It looks like a bird but has thrown off the theory of shrinking descent from Archaeiopteryx to the modern sparrow.  It is primitive but big.  

And now back to the study of mineralogy.  The next group is called skutterudite, named for the town of Skutterud in Norway.  I will admit that I asm more curious about the town of Skutterud than this mineral group, which includes smaltite and chloanhite.  It is a source of cobalt and can be found in numerous locations around the globe.  I really should go back and explain the molecular structure of minerals.  That aspect of the subject is beginning to intrigue me very much.   

But each day has only 24 hours and I have much to do.
