Needle Fish
Family Aspidorhynchidae (Bleeker, 1859)
Genus Belonostomus (Agassiz, 1834)
Belonostomus sp.
Age - late Jurassic to
Cretaceous (Paleocene?) - Occurrence - Scarce
Belonostomus, as the common name needle fish implies was a very slender and
elongated fish. The arrangement of the teeth amongst the species
is highly variable, having from 1 to 3 rows of teeth. The
larger teeth have longitudinal ridges along the shaft and are fused to
the underlying bone. Tips of these teeth bear light-colored acrodin caps that
are distinct from the rest of the tooth (Friedman, 2012). Belonostomus was first
reported from New Jersey Cretaceous in 2016. (Oman et al., 2016)
