Scheenstia is an extinct genus of neopterygian ray-finned fish from the Late Jurassic–Early Cretaceous periods. Fossils have been found in Bavaria, France, and England.
Scheenstia is frequently pictured as the prey of the dinosaur Baryonyx walkeri because the scales and teeth of these fish were found in the stomach region of a fossil B. walkeri specimen. The fish remains were previously referred to the related genus Lepidotes, but all Late Jurassic–Early Cretaceous species of that genus have since been re-classified as Scheenstia following detailed phylogenetic analysis.[1] It is a member of Lepisosteiformes meaning that is closest living relates are gars.
Classification[]
Scheenstia is related to the genus Lepidotes. The latter has been one of the greatest actinopterygian wastebasket taxa, with one 2012 study finding species referrable to a minimum of three different and distantly related genera. Scheenstia is also related to . A cladogram showing the relations of Neopterygii was published in the review, and a simplified version labelling the previous species of Lepidotes is shown here.[1]
