Caytoniales PPT: Caytoniales are an extinct group of seed ferns that thrived during the Mesozoic era, particularly in the Jurassic and Cretaceous periods. They are known for their unique reproductive structures, especially cupule-enclosed seeds that resemble the ovules of flowering plants. This similarity has led some scientists to propose a possible evolutionary link between Caytoniales and early angiosperms. Fossils of Caytoniales have been found in various parts of the world, indicating their wide distribution before extinction. This is a PPT on Caytoniales: General Characteristics, Distribution, Affinities and Examples.
