Piece description from the artist
Kronosaurus was a marine reptile that lived in the ocean during the early Cretaceous period at the same time dinosaurs roamed the land. Though sometimes called a dinosaur, it is technically a pliosaur which is different from dinosaurs. They were large, only a little shorter than the average length of a school bus and preyed on turtles and plesiosaurs and possibly giant squid and elasmosaurs. It is named for the ancient Greek titan Kronos.
