Hausmannia
Hausmannia is a genus of extinct ferns that lived during the Mesozoic Era, primarily from the Jurassic to the Early Cretaceous periods. These plants were characterized by their distinctive frond structure. The fronds were typically fan-shaped and deeply divided, with a fan-like or palmate arrangement of pinnae, or leaflets. This characteristic morphology is what gives the genus its name, referencing the German anatomist Johann Friedrich Meckel, whose Latinized name was Hausmann.
Fossilized remains of Hausmannia have been found in various parts of the world, indicating a widespread distribution
The ecological role of Hausmannia is inferred from its fossil occurrences, suggesting it likely grew in humid,
