Comments

Taxonomy from Fossilworks.

From Ebert 2014, p. 39: "Belonostomus sphyraenoides Agassiz, 1844 is known only from the Eichstätt basin. Belonostomus is very rare in the Plattenkalk basin of Eichstätt and as far as I know, all specimens belong to B. sphyraenoides. The Plattenkalk of Eichstätt is dated as eigeltingense β horizon of the Tithonian (Schweigert et al. 2013). Belonostomus sphyraenoides has about 71 vertebrae and 71 lateral line scales."
