Taxonomy:

Citation: Goniolithaceae Deflandre 1957
Taxonomic rank: family
Taxonomic discussion: This family includes just one genus and species - Goniolithus fluckigeri - but this species has unique morphology and it is not celar what its ancestors where so leaving it as an isolated family seems justified. [my interpretation - JRY 2025]

Original description: Caractères du genre type Goniolithus Defl. Par suite de ses caractères singuliers, le genre Goniolithus ne trouve place dans aucune des familles connues. Je crée donc pour lui al famille nouvelle des Goniolithida. Provisoirement cette famille se situera dans l'Ordre des Heliolithe, reliant peut-être celui-ci à l'Ordre des Ortholithe (analogie de forme avec Braarudosphaera, analogie de structure avec certains Discoaster).
