Daughter taxa (time control age-window is: 0-800Ma) | ||||
Alicantina prolata Like A. lozanoi but test smaller with 4–5 chambers in the final whorl, looser coiling and a lower spire. | ||||
Alicantina lozanoi Moderately high, evolute, trochospiral test, 5-6 globular chambers in final whorl; predominantly, intraumbilical aperture. |
Catalog entries: Alicantina
NB These concise distinguishing features statements are used in the tables of daughter-taxa to act as quick summaries of the differences between e.g. species of one genus.
Morphology:
Wall type:
Alicantina n. gen. evolved in the early Eocene presumably from a parasubbotinid-like taxon possessing a non-spinose wall texture and left no descendants. [Soldan et al. 2018]
