テリジノサウルス科

Also known as Therizinosaurid, Therizinosaurids

Therizinosauridae (meaning 'scythe lizards') is an extinct family of derived (advanced) therizinosauroid dinosaurs whose fossil remains have been found in mostly Late Cretaceous boundary. Even though representative fossils have only been found throughout Asia and North America, the range of Therizinosauridae is believed to have spanned much of the supercontinent of Laurasia based on several footprints and isolated remains in Europe and Africa. As of 2025, the family Therizinosauridae comprises nine definitive genera.
