Abstract
A new fossil belonging to the Lindsaeaceae is described as Proodontosoria myanmarensis gen. et sp. nov. from the mid-Cretaceous Myanmar amber. Its classification in the extant Lindsaeaceae is based on laterally fused vein tips that bear sori, indusia opening toward the segment margins, and trilete spores. The number of annulus cells and the size of sporangium suggest that the fossil probably belongs to a stem group element of this family.
