Name: Kwanasaurus ‭(‬Kwana lizard/alt.‭ ‬eagle lizard‭)‬.
Phonetic: Kwa-nah-sor-us.
Named By: J.‭ ‬W.‭ ‬Martz‭ & ‬B.‭ ‬J.‭ ‬Small‭ ‬-‭ ‬2019.
Classification: Chordata,‭ ‬Reptilia,‭ ‬Dinosauriformes,‭ ‬Dracohors,‭ ‬Silesauridae,‭ ‬Sulcimentisauria.
Species: K.‭ ‬williamparkeri‭ (‬type‭)‬.
Diet: Herbivore.
Size: Uncertain due to lack of remains,‭ ‬but comparison to other silesaurids suggests larger individuals possibly around‭ ‬1.5‭ ‬meters long.
Known locations: USA,‭ ‬Colorado‭ ‬-‭ ‬Chinle Formation.
Time period: Norian of the Triassic.
Fossil representation: Partial remains of several individuals,‭ ‬including partial skull and jaw bones,‭ ‬teeth,‭ ‬and fore and hind limb bones.

       Classed as a silesaurid‭ (‬relative of Silesaurus‭)‬,‭ ‬Kwanasaurus is a herbivorous dinosauromorph that lived in North America during the late Triassic.‭ ‬Dinosauromorphs include the ancestors of the dinosaurs,‭ ‬but the appearance of‭ ‬Kwanasaurus in the late Triassic when true dinosaurs were already roaming around suggests that Kwanasaurus,‭ ‬and other silesaurids were evolutionary off shoots from this base group.‭ ‬Kwanasaurus is one of the northern most known silesaurids.
       Kwanasaurus is known for having a skull that at the time of its description‭ ‬is‭ ‬deeper and more robust‭ (‬strongly formed‭) ‬than other silesaurids.‭ ‬Some of the teeth in the jaw were rounded but most are more leaf-shaped and strongly attached to the tooth bearing bones.‭ ‬These features all point to Kwanasaurus being well adapted for eating the tougher plants of the Triassic,‭ ‬that were possibly too much for lighter built plant eaters to deal with.
       Kwanasaurus is based upon the Ute word‭ ‘‬kwana‭’ ‬which means‭ ‘‬eagle‭’‬.‭ ‬This is in reference to the town of Eagle in Colorado which is close by to where the fossils of Kwanasaurus were found.
