Because fern is a popular plant now and in the dinosaur days
No current plants, but some fossil imprints are of long dead plants (usually from about 1/4 billion yeas ago).
How many ferns (that is a plural!) between the trees?If there are equal numbers of ferns in between each pair of trees: Five times as many ferns as between one pair.
Ferns and their fossil remains have been found on every continent
The plants known as seed ferns were ancient, fern-like plants that produced seeds instead of spores for reproduction. They thrived during the Paleozoic and Mesozoic eras, with fossil evidence indicating they were widespread and diverse. Despite their name, seed ferns were not true ferns, but early gymnosperms that eventually gave rise to modern seed plants.
Animal parts that are soft and don't have a skeleton leave the worst imprints. Fossils are made with animal parts that are hard and durable.

Fossil.
A fossil is the preserved remains or traces of a once-living organism, while an imprint is a mark or indentation left behind by an organism on a surface. Fossils can include imprints, but not all imprints are considered fossils. Fossils provide more detailed information about the organism's structure and biology, while imprints are more surface-level.
yes, but they are only usually imprints as sponges decompose after a certain amount of time
pressure and heat
The ferns have been compressed into 'coal' and we use coal as a source of energy - hence 'fossil fuels'.
Ferns appeared in fossil records about 360 million years ago.

It takes several millions of years for a fossil to be created. First an animal may step in mud whichs dries over time and becomes hard. After it has that mold the conditions have to be right for it to form. If they are then it will form.
