Phyllotheca is an extinct genus of equisetalean, related to modern horsetails. It is known from the Permian period,[1] as well as possibly the Carboniferous.[2] It was named was created in 1828, when Brongniart described the type species Phyllotheca australis coming from Hawkesbury River, Australia.[3]
Species
- Phyllotheca australis: Initially described by Brongniart coming from Australia.
- Phyllotheca brevifolia: Described by Roesler, Boardman and Iannuzzi. Found in Paleorrota geopark on Morro Papaléo in Mariana Pimentel, Brazil. The area is in Rio Bonito Formation dating from Sakmarian in the Permian.
- Phyllotheca indica: Described by Towrow in 1955. Coming from India.
- Phyllotheca longifolia: Described by Roesler and Boardman. Found in Paleorrota geopark on Morro Papaléo in Mariana Pimentel, Brazil. The area is in Rio Bonito Formation dating from Sakmarian in the Permian.[4]
Claimed records from the Jurassic of Poland are doubtful and may represent Neocalamites instead.[5]
