The Zygopteridales is an extinct order of ferns or fern-like plants which grew primarily during the Carboniferous The Carboniferous ( ) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago ( Mya), to the beginning of the Permian Period, million years ago. The name ''Carbonifero .... It comprises two families: Zygopteridaceae, which contains at least a dozen named genera, and Teledeaceae, which comprises two genera ('' Teledea'' and '' Senftenbergia'').

Zygopteridaceae
Zygopteridaceae is a family of ferns or fern-like plants which lived from the Frasnian to the Berriasian (possibly as far as Cenomanian). It was first thought to have gone extinct during the Permian or the Triassic, but fossil wood assigned to Yulebacaulis was found in rocks from Queensland which are at least Berriasian in age, and palynological records indicates that the family may have survived until Mid-Cretaceous. Description Zygopteridacean ferns were mostly herbaceous, with small weak stems and small fronds. Some genera, however, were up to 10 feet tall, with medium-sized trunks supported by a large mantle of roots and fronds reaching up to 5 ft long. They had a cosmopolitan distribution, being found both in Laurasia and Gondwana. References * Thomas N. Taylor, Edith L. Taylor, Michael Krings: Paleobotany.
