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.

the spelling
Tree ferns and palm trees are both types of tropical plants, but they have distinct differences. Tree ferns are a type of fern that have a woody trunk and large, frilly leaves, while palm trees have a smooth, slender trunk and large, fan-shaped or feather-like leaves. Additionally, tree ferns reproduce via spores, while palm trees produce seeds. Overall, tree ferns are more closely related to ferns than palm trees are.
Trees are vascular and ferns not
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).
