Knightia was a freshwater schooling fish with a maximum length of 25 centimeters and an important food for predatory fish . It is always found in masses in fossil form. It is therefore believed that they often fell victim to events such as algal blooms .
The first Knightia fossils were found in the 1840s by missionaries and explorers traveling across the American West to explore Wyoming. The genus was named after the geologist Wilbur Clinton Knight . Knightia is the state fossil of Wyoming.
The following species are known, K. branneri , K. alta and the type species K. eoceana . "Knightia brasiliensis" from the " Tertiary " of Brazil was placed in the genus Paleopiquitinga by De Figueiredo in 2010 due to anatomical differences .
