Kordatavus
Kordatavus is a genus of extinct ray-finned fish that lived during the Late Jurassic period. Fossil remains of Kordatavus have been discovered in marine sedimentary rocks, primarily in what is now Europe. These fossils indicate that Kordatavus was a relatively small fish, typically measuring no more than a few centimeters in length. Its anatomy suggests it was a nektonic organism, meaning it swam actively in the water column rather than dwelling on the seafloor.
The skeletal structure of Kordatavus reveals adaptations for a pelagic lifestyle. Its fins were likely used
