The newly identified species, dubbed Rutiotomodon tytthos, is a trilophosaur—a group of lizard-like reptiles that roamed the Earth in the Triassic Period (roughly 252-201 million years ago) around the time that dinosaurs first appeared.
Trilophosaurs are somewhat closely related to dinosaurs, sharing a common ancestor and forming part of the same wider group of animals known as the archosauromorphs. Archosauromorphs include a sub-group called the archosaurs as well as their closest relatives. Trilophosaurs are among these related sub-groups.
In the geological past, archosaurs were represented by dinosaurs, except birds, pterosaurs, and various species closely related to these major lineages. Today, they are represented by crocodilians and birds.
