- Spinacanthus cuneiformis Spinacanthus Vue d'artiste de Spinacanthus cuneiformisde l'Éocène du Monte Bolca (Italie). Genre † SpinacanthusAgassiz, 1835 Espèce † Spinacanthus cuneiformisde Blainville, 1818 Spinacanthus est un genre éteint de poissons osseux marins de la famille des Protobalistidae, du sous-ordre des et de l'ordre des Tetraodontiformes, un taxon qui comprend essentiellement des poissons marins vivant aujourd'hui à l'intérieur et autour des récifs coralliens. Une seule espèce est attribuée à ce genre : Spinacanthus cuneiformis, décrite en 1818 par le paléontologue français Henri-Marie Ducrotay de Blainville. Une seconde espèce du Monte Bolca, décrite par L. Agassiz en 1835, Spinacanthus blennioides n'est plus retenue aujourd'hui. (fr)
- Spinacanthus cuneiformis is an extinct prehistoric tetraodontid bony fish that lived from the Lutetian epoch of Eocene Monte Bolca. In life, it would have resembled a somewhat-flattened boxfish with five long spines along the anterior-dorsal side, with the longest spine directly above the forehead, and the shortest spine directly in front of the dorsal fin. It is distinguished from its close, sympatric relative, Protobalistum, in that its individual scales are relatively small, and do not touch each other. (In Protobalistum, the scales are large, and form a sort of armor). S. cuneiformis and Protobalistum were a part of the ecosystem of the lagoon that became Monte Bolca. Because of their similarity to boxfish, and due to their close relation to modern-day triggerfish, spinacanthids may have preyed on shellfish and small fish. (en)
