Hello again fossil gurus! I went to per state park again today and found over 80 shark teeth and shark tooth fragments! It was really great. I also found these three little bits which I thought were intriguing, particularly the middle one. Is it a bone fragment!? I apologize for the picture with my hand, but it was the one that seem to catch the texture inside the best. Any ideas on what the others are? They were all found near the waters edge. Thanks so much!
