Very possibly, or else different parts of the branches of the same trees,
or some other difference in manner of removal.

I seriously doubt sauropods could eat cycads.
Those cycads I am familiar with all have large, prickly, rigid leaves.
Not the sort of thing the teeth of a sauropod could easily deal with,
even if used only to pluck the leaves.
I suspect that cycadeoids may have been similar.
The largest tree ferns and seed ferns were no longer present in
This leaves the gingkoes, which are a distinct possibility, and were
at least regionally common at the time.
The peace of God be with you.
