Comparison to human
Haya griva is an extinct genus of thescelosaurine ornithischian found in Mongolia. The genus ranged from 86 to 84 million years ago in the Santonian age of the Late Cretaceous. Its size was 1.6 meters(5.2 feet).
Description[]
Haya is known from several well-preserved specimens which collected in the Khugenetslavkant locality by the joint Mongolian Academy of Sciences from 2002 to 2007, from the Javkhlant Formation. The locality probably dates to the Santonian stage of the Late Cretaceous. The holotype IGM 100/2017 is composed of a complete and well preserved skull with some postcranial elements associated to it. Referred materials include IGM 100/1324, isolated left femur, IGM 100/2013, postcranial elements, IGM 100/2014, a crushed skull and postcranial elements, IGM 100/2015, a nearly complete postcranial skeleton, IGM 100/2016, a partial juvenile skull, IGM 100/2018, an isolated mandible with some teeth, IGM 100/2019, a nearly complete skull and skeleton and IGM 100/2020, postcranial fragments. One skeleton of Haya, IGM 100/2015, preserves a large mass of gastroliths.
Etymology[]
It was named after the Hindu god of knowledge and wisdom, Hayagriva. It's bones were found in the Javkhlant Formation and named in 2011 by Peter Makovicky.
Phylogeny[]
It was found to be closely related to Jeholosaurus and Changchunsaurus, even forming a possible clade known as Jeholosauridae.
