Dictyozamites barnardi sp. 11和Dictyozamites fakhri sp. 11是在伊朗和中东地区发现的第二种和第三种Dictyozamites。它们来自伊朗北部Alborz山脉Ramsar地区的Rhaetic Kalariz组(Shemshak组)。Dictyozamites barnardi sp. 11 .的主要特征是短而弯曲的强镰形的羽状基部和明显的耳状基部，Dictyozamites fakhri sp. 11 .的主要特征是其长而略镰形的非常细长的三角形羽状基部，相对于近对生的羽状位置，明显的耳状。关键词:双氧杂石，雷蒂安，卡拉里兹组，伊朗resume - Dictyozamites barnardi sp. 11月11日- Dictyozamites fakhri sp. 11月15日- a - seunda - terceira espacemcies de Dictyozamites a - seras描述了第Irã段的描述。Elas衍生am da forma o Kalariz (Grupo Shemshak, r) da área de Ramsar, Alborz Mountains, north do Irã。Dictyozamites barnardi sp. 11 .区分-特别区分pelas pinas curtas, curtas, fortemente falcadas, clamente aurculadas, clamente falcadas, trangulares longas, ligeiramente falcadas, muito adas, postas, ponstas, ponstas, subpostas, clamente aurculadas。Palavras-chave: Dictyozamites, r， forma o Kalariz, Irã。
Two new species of Dictyozamites (Bennettitales) from the Rhaetic Kalariz Formation, North of Iran
Dictyozamites barnardi sp. nov. and Dictyozamites fakhri sp. nov. are the second and third species of Dictyozamites to be described from Iran and the Middle East. They derive from the Rhaetic Kalariz Formation (Shemshak Group) of the Ramsar area, Alborz Mountains, North of Iran. Dictyozamites barnardi sp. nov. is distinguished especially by the short and curved to strongly falcate pinnae and clearly auriculate bases and Dictyozamites fakhri sp. nov. is distinguished particularly by its long, slightly falcate and very elongated triangular pinnae, opposite to sub opposite pinnae position and clearly auriculate. Keywords: Dictyozamites, Rhaetian, Kalariz Formation, Iran. RESUMO – Dictyozamites barnardi sp. nov. e Dictyozamites fakhri sp. nov. são a segunda e terceira espécies de Dictyozamites a serem descritas para o Irã e o Oriente Médio. Elas derivam da Formação Kalariz (Grupo Shemshak, Rético) da área de Ramsar, Alborz Mountains, Norte do Irã. Dictyozamites barnardi sp. nov. distingue-se especialmente pelas pinas curtas e curvas a fortemente falcadas e bases claramente auriculadas e Dictyozamites fakhri sp. nov. distingue-se particularmente pelas suas pinas triangulares longas, ligeiramente falcadas e muito alongadas, opostas à posição das pinas subpostas e claramente auriculadas. Palavras-chave: Dictyozamites, Rético, Formação Kalariz, Irã.
