Biology:Aculea
From HandWiki
Aculea is an extinct genus of ferns known from the Cretaceous period, primarily identified through fossil records in places like Antarctica and Australia.[1][2] 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.[1]
Description
Fossil evidence suggests that individual plants could grow into dense thickets reaching up to 80 cm in height. The fronds were slender and rigid, bearing narrow, acicular (needle-like) pinnae. This morphology likely provided structural support in open or patchy forest environments.[1]
