Historical Identity
The scientific name retained here is Moxostoma lacerum. Historical fish records and preserved specimens are the relevant evidence for an extinct species. A modern photograph of a superficially similar sucker should not be assigned to this name without exceptional supporting documentation.
Reading the Record
The compiled account identifies a freshwater, bottom-associated fish formerly present in the United States. Its historical distribution should not be displayed as evidence of present-day occupancy. Collection dates are therefore central to understanding locality information rather than optional additions to a map point.
Measurements and Limits
The published historical length reference is 31.3 centimeters standard length, which excludes the tail fin. A separately verified maximum weight is not retained. Limited surviving biological information also means that an ordinary modern sucker’s spawning calendar or feeding description cannot fill every gap in this species’ history.
Treat Localities as Historical
An old collection locality records where the species once occurred. It is not evidence of a surviving population or an invitation to target the fish.
