I am new to this site and hope to get some input and any information I can about my pipe. I found this pipe many years ago and have in the last few years tried to find out more about what culture it belong's to with not much success.  This is what I can tell you about my pipe. I found it on a small Island/shell bar off the North central Gulf coast of Florida.  It is made of a dense type of limestone? It is 7 1/2" long 4 1/4" high and 2 3/4" wide and is of a bird effigy . Some of you may have heard about it before and have seen it on other sites. So any help will be appreciated.

Thanks
William
