Hi Lady. Let me start by saying I know nothing. The first pic made me think of a ceramic high school art project that had been in a house fire or really acidic ground. The alien made me think of 1970's 6" tall statues of droop eye dogs, very popular at the time,that had been in a house fire. The green glass looking thing with the "bug-fly" kind of freeked me out because I do see "something", but the eye wants to see familiar things like the words written in gibberish you can read because of a couple of key letters in the right place. I would guess some kind of flaw and not a bug.
In post #11,third pic., I do see 40 or 50 "U or V". About the middle of the object. All of the "U or V"'s have the horn points up. In the first pic. of the post I see like 8 of them. 5 in one bunch, 3 in the other. They are along the upper right edge. Those horns are pointing down. They are white. I would guess that's an anomaly of the camera. Dust on the lens,reflection off of the object, the way the digital cameras photograph. On the left middle I also see Porky Pig in a waist jacket,holding a golf club head behind him with his right hoof. He is also white. But I have an imagination.
You say the whole area was formed by meteors. Could you tell us where this is? You also said you had sent some to a lab for testing and it was radioactive. Is it enough to cause health problems? If so I'd stay away from it. Good luck in getting it identified.
