Well, if it's only a rock, and not an artifact, isn't it simply being honest to inform the poster that it's not an artifact? It's extremely obvious that it's not an artifact. Why inform the poster that it is an artifact? This is not a perfect example of why not to post to this section of treasurenet. It is an example of what can happen, short and to the point replies, when one posts something that is simply not what the poster believes it to be. Would it really be better to say "hey, nice effigy pipe! Welcome!" Paleo Lonewolf, there was no real need for anybody here to say your case was not proven yet, instead of telling you it's just a rock. The reason there was no reason to tell you your case was not proven is because your photos were enough to disprove your case. You may believe otherwise, and that's your right, but experienced eyes can see it's not an artifact. Trouble is, sometimes short and to the point seems rude when it really is not intended as such. Welcome to the forum. A great many experienced collectors here.
If I were a dealer/experienced collector at an artifact show, and you showed me this rock, asked what I thought, and I could see a look of excitement and anticipation of good news on your face, I would let you down as gently as I could muster. But I would have no choice but to let you down. Person to person is different, isn't it....
