Here are the sorts of questions I would ask myself looking at your photos, to try and determine what had happened.
I have added a couple of labels to the photo below.
The dried scape looks like it is between the two fans. The question becomes, was there originally only one fan and it produced that scape and then all its leaves aged and dried? If there was only one original fan did it produce two replacement fans?
On the photo below I have labelled several leaves with numbers.
Leaf 1 looks like the last leaf produced before the scape beside it. Its length would need to have been measured.
Leaf 2 looks like a fragment of the next leaf produced after the scape beside it - Its length (entire) would need to have been measured.
Leaf 3 looks like the last leaf produced before the next scape. Its length would need to have been measured.
Leaf 4 looks like the first leaf produced after the scape beside it. Its length would need to have been measured.
