  Hiodontiformes
The Hiodontiformes are represented by two extant species, Hiodon alosoides (goldeye) and Hiodon tergisus (mooneye), which occur in fresh waters, both lakes and streams, of the interior of North America east of the Rocky Mountains.
Living species of hiodontiforms are endemic to interior fresh waters of North America east of the Rocky Mountains.
Extinction must have been important in the Cenozoic history of the order (Li, Wilson, and Grande, 1997): the present endemic distribution of the Hiodontiformes is thus a remnant of a former widespread northern hemispheric distribution (Wilson and Williams, 1993).

 Hiodontiformes
The earliest fossil Hiodontiformes thus far known in North America are Eocene species of †Eohiodon (Cavender, 1966; Wilson, 1978; Grande, 1979; Li, Wilson, and Grande, 1997).
This relationship is supported by at least two synapomorphies uniquely shared by these two genera in the Hiodontiformes sensu stricto Li and Wilson (1996): supraorbital canal ending in frontal, anal fin in male and female sexually dimorphic.
This is seen in all hiodontiform species and is also unique to the order (Li and Wilson, 1996a, in press; Li, Wilson, and Grande, 1997).

 Mesozoic Fishes – 2: Systematics and Fossil Record
Recent phylogenetic studies of Osteoglossomorpha suggest instead a monophyletic Hiodontiformes sensu stricto, sister to Osteoglossiformes and with a minimum age range of Early Cretaceous to Recent.
This study confirms that †Yanbiania is the earliest representative of the Hiodontiformes yet known, and that the five hiodontiform synapomorphies (dermosphenotic triradiate, opercle an irregular parallelogram, hyomandibula double-headed, dorsal arm of posttemporal more than twice as long as ventral arm, and seven-rayed pelvic fin) were already present in †Yanbiania.
The 'Mid'-Cretaceous †Plesiolycoptera is considered to be a stem-group hiodontiform because of the presence of a triradiate dermosphenotic, a posttemporal with a dorsal arm at least twice as long as the ventral arm, and a seven-rayed pelvic fin.

By examining the growth patterns of contemporary pike and yellow perch across their ranges, I have found that mean annual air temperature describes variation in growth.
Furthermore, changes in age and growth of Esociformes and Hiodontiformes since the Cretaceous show trends in time that are correlated with climate change.
Pleistocene fossils can also be used to examine the effects of climate change on fish.
