Weichselia is an extinct genus of fern. They were abundant from the Middle Jurassic to Early Cretaceous.[1] While generally considered members of Matoniaceae, some research has suggested that they have closer affinites to the Marattiales. They grew similar to modern tree ferns, with an upright stem topped with a crown of fronds.[2]

Distribution

Fossils of Weichselia have been found in:[1]

Jurassic (to Cretaceous)

Algeria, Egypt, Georgia, Israel, and Peru.

Cretaceous

Belgium, Colombia (Caballos Formation, Tolima),[3] Germany, Egypt (Bahariya Formation),[4] Sudan (Jebel Dirra),[4] Israel, Spain, the United Kingdom, and the United States (Wyoming).
