I am not sure how long giant tree ferns have existed, but ferns have been around since the mid Devonian, about 380 million years ago. Palm trees first evolved about 80 million years ago, during the Cretaceous. Ferns diversified during the Cretaceous, and palms diversified by 60 million years ago, just after the extinction of the dinosaurs.

What is the difference between tree ferns and palm trees?
Tree ferns are a type of fern that have a trunk-like structure composed of old leaf bases, while palm trees are flowering plants with a woody trunk and large leaves at the top. Tree ferns do not produce flowers or fruits like palm trees do. Additionally, tree ferns are typically found in moist, shady environments, while palm trees thrive in tropical and subtropical regions.

How are conifers different from ferns?
The word conifer literally means, cone bearing. It refers to trees such as pine trees, which produce pine cones. Such trees are vastly larger than ferns, which are little plants that grow to something like 2 or 3 feet in height at the most. Ferns are also a more primitive form of plant. Trees have trunks made of wood, ferns do not have woody stems. Trees reproduce by means of seeds, ferns reproduce by means of spores (which are like seeds only smaller).
