wide, normally flat to convex. Seven to nine (frequently eight), convolutions are visible laterally. Apex flat or slightly convex. Spiral cells do not show constrictions in the apical periphery but display marked thinning in the apical zone, resulting in an apical to periapical depression. In some gyrogonites, the apex is ornamented by tubercles that vary notably in size depending on the specimen. Ŋe base is rounded with a large and superficial basal pore about

, from the A’Court Smith collection at the Natural History Museum, London, belonged precisely to the few specimens which displayed a prominent apical rosette and this character was further considered as diagnostic of the species, rather than as merely an extreme version of its total morphological variation. Taking into account this range of variation, the main difference between the material from the Ebro Basin and the type material is the size of the gyrogonites, which are about
