Acipenser is a
genus of
sturgeons . With 17 living species (others are only known from
fossil remains), it is the largest genus in the order
Acipenseriformes . The genus is
paraphyletic , containing all sturgeons that do not belong to
Huso ,
Scaphirhynchus , or
Pseudoscaphirhynchus , with many species more closely related to the other three genera than they are to other species of Acipenser . They are native to freshwater and estuarine systems of Eurasia and North America, and most species are
threatened .
[2] Several species also known to enter near-shore marine environments in the Atlantic, Arctic and Pacific oceans.
This is an ancient genus, with fossil species known as far back as the
Late Cretaceous . In fact, the fossils of two species (
A. praeparatorum and
A. amnisinferos ) are known from
mass mortality assemblages immediately following the
Chicxulub impact , the beginning of the
Cretaceous-Paleogene extinction event .
