A giant therapod herbivore with giant claws that are speculated ot be a defencive mechanism, and to manipulate plants.
It likely had long feathers along their neck and arms like that of a roosters or pigeons, perhaps for display.

not much is known about this animal, but I love them, giant murder turkeys!

drew two concepts with not puffy tail and with one, but there is no proof of a puffy feather duster tail...but it looks cool
