在新西兰奥塔哥早中新世的Foulden Maar硅藻土矿床中，描述了具有孢子囊和原位孢子的现存蕨类属（水蛭科：Davallia科）的化石蕨类叶子。这些叶子是首次发表的南半球大化石记录，并提供了有价值的古气候数据，支持中新世早期新西兰的温暖条件。Davallia叶片与孢子分类群Polypodiisporites radiatus的匹配表明，Davallia属在晚新生代新西兰有一个漫长而明显连续的历史。(C) 2010 Elsevier B.V.版权所有
Fossil fern fronds referable to the extant fern genus Davallia (Polypodiales: Davalliaceae) bearing sporangia with in situ spores are described from the Early Miocene Foulden Maar diatomite deposit, Otago, New Zealand. The fronds are the first published Southern Hemisphere macrofossil record for the family and provide valuable palaeoclimate data supporting warm conditions in Early Miocene New Zealand. The matching of Davallia fronds to the form spore taxon Polypodiisporites radiatus shows that the genus has had a long, apparently continuous history throughout late Cenozoic New Zealand.
