Hello. This is my first post. I have little experience in fossils except perhaps an eye to notice they're not quite a rock. I "think" this is a fossil tooth. Found in Tennessee, USA, Mid-Ordovician area in general; at approx 1,100 altitude in the dry portion of a chronically drought stricken river. Partially mineralized and lying where 100-200+ old trees are. Their roots are exposed; fossil wood can't be ruled out. I appreciate your thoughts. I'm a professional rock hound of 10 years with 60 years of accumulated knowledge. Science has sheets fascinated me; geology is involved in my life's work at this time. But I can't validate this! I'm currently cleaning it to remove some of the calcite-concrete. It bubbles a little in a vinegar solution, but not much. Thank you in advance!

During my last visit at Bødalen, I found my second trilobite at the location, similar to the first one presented at this forum, mid-Ordovician and probable in the Ptero elegans zone. In the same stone there is also several puzzling forms, among them circular patterns. Anyone have an idea what these are? The length of the bigger oval or circular pattern is about 4-5 cm, that is the longer side.
