It contains the following species: •
C. brasiliensis -
Aptian of
Bahia, Brazil (
Marizal Formation) •
C. maroccanus -
Cenomanian of
Morocco (
Jbel Tselfat), late Cenomanian/early
Turonian of Germany (
Hesseltal Formation) Fossils of an indeterminate
Clupavus species are abundant in the
Albian-aged
Pietraroja Plattenkalk of Italy, and the Cenomanian-aged
Komen Limestone of
Slovenia. A few specimens of a potential indeterminate species are also known from the Albian-aged
Mowry Shale of
Wyoming, USA. The genus was initially described in 1950 with the species
C. neocomiensis (Bassani, 1879) as its type species, based on a specimen from Morocco classified
C. cf.
neocomiensis. In 1968, the original
C. neocomiensis was found to be synonymous with
Leptolepis brodiei, so
Clupavus was redefined with the newly-described
C. maroccanus as the
type species. The classification of
C. brasiliensis in this genus has been questioned, as it differs from
C. maroccanus in the morphology of the caudal skeleton. The species
Casieroides yamangaensis and
Chardonius longicaudatus from the
Democratic Republic of the Congo were initially classified in this genus, but are now known to be unrelated. Relatives of
Clupavus include
Lusitanichthys and possibly
Jhingrania. == Ecology ==
