Aculea is an extinct genus of ferns known from the Cretaceous period, primarily identified through fossil records in places like Antarctica, Australia, and Patagonia. Additional mid-Cretaceous fern diversity studies in Patagonia have further documented the stratigraphic context of fern genera, including Aculea, within Cretaceous South American plant assemblages. It includes species such as Aculea acicularis, which formed upright thickets with fronds arising from subterranean rhizomes, often in environments dominated by araucarian trees and other large plants and floodbasins. Its fossils have also been recovered from floodbasin settings, notably from the Eumeralla Formation.
