The imprint in the pictures looks like a Cycad, termed a living fossil, and not to be confused with a palm or fern.
It would help to know the age of the sandstone in which this is found.
My best guess:
It does appear to be a plant, flora, and being found in sandstone would indicate, to me, that this particular specimen, a frond or branch, was in a
near-shore environment. The frond may have been transported by wind, water, animal, to the surface of the body of water, where it became water logged
and sank. It was probably rapidly covered by additional sand, where it was protected from wave action
One of the hardest things for a geologist is to determine something solely being shown photos. If you could possibly take it to a paleobotanist in
your area, he/ she may be able to identify it. If you do make a cast, that would be ideal to take in addition to, or instead of the specimen.
Keep us posted as to your findings... the answer is out there.
