Quantitative and qualitative frond analysis of the fern Cladophlebis: Distinguishing morphotypes from the Barremian locality of Las Hoyas (southwestern Iberia Basin, Cuenca, Spain)

Cladophlebis is a very variable form genus of Mesozoic fern foliage. At the Spanish Konservat Lagerstätte of Las Hoyas (upper Barremian), several pinnae that could be assigned to this genus have been unearthed. The identification of different species is complicated due to the high morphological disp...

The identification of different species is complicated due to the high morphological disparity of the sample. Therefore, a quantitative and qualitative analysis was performed using 16 different characters that were explored by means of a Principal Component Analysis, resulting in the identification of three different morphotypes that closely agree with the descriptions of three previously proposed Cladophlebis species: Cladophlebis albertsii, Cladophlebis browniana, and Cladophlebis dunkeri.
