A new dasycladalean green alga is described as Milanovicella? canadillana from the Upper Cretaceous (middle Santonian–lower Campanian) of northeastern Spain. It occurs in foram-algal wackestones of the La Cañadilla Formation ascribed to a shallow marine (hyposaline?) to coastal environment. The associated microfauna is dominated by miliolids. The generic uncertainty of the taxon displaying multiple, often double verticils (= excluding Clypeina) refers to its unknown starting point with respect to the main axis and the overall thallus morphology. The calcified skeleton of M.? canadillana appears to consist of yellowish fibrous calcite as noted within some genera (e.g., Salpingoporella, Clypeina) and a handful of species discontinuously reported from the Mesozoic and Paleogene dasycladale record. The new taxon expands the diversity of calcareous algae during the Santonian – Campanian interval, that has previously been regarded as comparatively low.

一种新的 dasycladalean 绿藻被描述为Milanovicella ? canadillana来自西班牙东北部的上白垩统（中桑托世 - 下坎帕世）。它发生在 La Cañadilla 组的有孔藻泥岩中，归因于沿海环境的浅海（低盐？）。相关的微型动物以粟科动物为主。显示多个，通常是双垂直的分类单元的一般不确定性（= 不包括Clypeina）是指其关于主轴和整体菌体形态的未知起点。M.的钙化骨骼。 ? canadillana似乎由淡黄色纤维状方解石组成，如某些属中所述（例如，Salpingoporella, Clypeina ) 和少数从中生代和古近纪 dasycladale 记录中不连续报道的物种。新的分类群扩大了桑托尼-坎帕尼期钙质藻类的多样性，而这在以前被认为是相对较低的。
