I am generally lousy at spotting fossils. Probably saw this mastodon tusk without really seeing it on previous visits to this shoreline bluff. I only saw it on a trip a while back because I was looking for something else at the exact same spot which allowed enough time for the presence of the tusk to sink in to my fossil blind brain.
Technically it is not a fossil, but a much decayed remnant of a part of the animal that in this case perished approximately 19,000 years ago according to my interpretation of the deposit the tusk was located in. Probably best to leave the specific location out.
