(Turtle-like scythe lizard)EtymologyThrerizinosaurus is derived from the Greek "therizo" meaning "to reap" or "to cut off" (with a scythe) referring to its scythe-like claws) and "sauros" (lizard).
The species epithet, cheloniformis, means turtle-form (or turtle like) because of Maleyev's 1954 assumption that it was some kind of gigantic turtle-like reptile.
DiscoveryThe first fossils of Therizinosaurus were discovered in the Nemegt Formation of southwestern Mongolia, by the USSR Academy of Science's Mongolian Paleontological Expedition in 1918.
The holotype (PIN 551/483) is a bunch of limb bones.
