And given the whole premise of the piece is “this should not be here!” I don’t really understand the point you’re making. The author says it’s a strange find in that area - so either they have a valid point or they don’t.
I don’t know if it’s a fossil. It doesn’t look like a fossil to me. I’m not a fossil expert. The only way to tell if it is a fossil is to do some analysis on the actual specimen before writing screeds about what it might or might not be based on visual similarity.
It's visibly very clearly a fossilized sea shell. You are being a useless pedant about the author's choice of verbiage.
Remember, the same author says "I found a seashell in the middle of the desert!" "shouldn't be here" and "coastline 500 miles"
And that analysis finds out that the shell the assumed fossil most resembles is completely out of period.
And I think you’re arguing yourself into a hole here.
What makes you think I know nothing about the topic? I have donated - at their request - three fossils to national museums.
But I’m not an expert by any stretch.
