Resolving taxonomic problems through cuticular analysis in Early Cretaceous bennettitalean leaves from Patagonia

The genus Ptilophyllum Morris is one of the most common bennettitalean leaf genera found in the Cretaceous megafloras from Western Gondwana, particularly Patagonia and Antarctica. Among several specimens, the similarity in the morphology of their leaves make them hard to distinguish from each other, which usually leads to misinterpretations. Therefore, the study of the epidermal features in this taxon is essential, especially because the...
