Well, if we WERE created 7,000 years ago by some benevolent all-seeing being, that being went to a lot of trouble to convince us otherwise. The Myanmar specimen from last year--they found it in an open-air village market near the Chinese border--was thought to contain some kind of plant material along with a valuable insect. That's not plant material, though. That may be the single most valuable hunk of amber ever excavated, because that's a section of a dinosaur tail and it still has visible structures shaped like a rooster's "hackle" (neck) feathers! Too bad anyone in the US who wants to see it will have to go wherever the amber is, as we still have a full trade embargo against Myanmar (formerly Burma). This is strongly felt in the world of geological and gemological collecting, as several unique stones come only from that area. Maw-Sit-Sit, known from one deposit near a village by the same name, is a beautiful mixed-blend stone I think turned out to be at least partly jade when tested. Octahedral spinel is found there, and while that's not unique the combination of vivid red color, the number of spinel crystals with perfect, clean, unchipped edges sticking out of a marble matrix so white it almost hurts to look at is unique. Rubies, of course, are another big one though there are quite a few other sources worldwide. And amber. Sure, Baltic amber has the best variety of inclusions, while the Dominican Republic and a couple other places produce amber that can be blue or green. But a perfectly preserved section of dino tail, right down to unbroken feathers? That's unique so far! It does advance the validity and acceptance in the paleontological community of the whole "feathered dino" idea. Rocks are great, particularly several individual fossils such as part of an infant T. Rex with down feather impressions around the visible skin and some that have preserved feather structure so well that microscopically visible structures within those feathers tell us they were iridescent. Now that too would be amazing to find in amber someday--dino feathers with bright colors or high shine preserved! The one in the post reminds me a lot of both my mom's chickens and the Jurassic movie franchise raptors, which it turns out may also have been feathered for at least part of their lives. |
