Leedsichthys is an extinct genus of pachycormid fish that lived in the oceans of the Middle to Late Jurassic. [1] It is the largest ray-finned fish, and amongst the largest fish known to have ever existed. [2] The first remains of Leedsichthys were identified in the nineteenth century.
This fish holds the dubious distinction of being the fish species lost from the largest number of American states—eight. [3] The last specimen was collected in 1893. By 1970, the species was believed to be extinct. The only known collection in Alabama came from Cypress Creek, Lauderdale County, in 1889.
Rhenanida ("Rhine fish") were flattened, ray-like, bottom-dwelling predators with large, upturned mouths that lived in marine environments. The rhenanids were once presumed to be the most primitive, or at least the closest to the ancestral placoderm, as their armour was made of unfused components—a mosaic of tubercles—as opposed to the ...
Among the fish that have been caught were about equal numbers of males and females. [8] Population estimates range from 210 individuals per population to 500 per population.
