We need to do that soon. And I DO want to see this fossil.
The photo of the frond is at

Maybe the photo doesn't do the rhythmites justice, because the rhythmites I
have seen have a stronger banding to them. I will order the article to
read up on the mansfield. I might note that the fossil seems very bold
which would imply a relatively strong leaves.
