[D] Beipiaosaurus inexpectus [Su] [sG] [T]
Describer
Xu, Tang & Wang, 1999
Time
Cretaceous Early Aptian
Classification
Saurischia Theropoda Tetanurae Coelurosauria Therizinosauroidea
Diet
Carnivore
Fossilsite
Yixian Formation, Sihetun locality near Beipiao, Liaoning, China
Length
2.2 meter
Info
Genus - Typespecies - Skull
These fragmentary remains discovered in 1996 also contains a number of articulated bone pieces. It gives us more precious information on a little-understood group of dinosaurs, and distinguishes itself as the fourth non-avian theropod dinosaur genus found with the remains of integumentary fibers -- all from the same region of China.
Beipiaosaurus inexpectus is named after the city near the locality where the specimen was found; and is referring to the surprising features in this animal. Holotype. IVPP V11559 (Institute of Vertebrate Paleontology & Paleoanthropology, Beijing, China).\\\\\\\"
Beipiaosaurus inexpectus differs from other therizinosauroids in having shorter and more bulbous tooth crowns, a larger skull, a tridactyl pes with a splint-like proximal first metatarsal, a shallow anterior iliac process, a long manus (10% longer than a femur), a long tibia (275 mm > 265 mm of the femur), an elongated lateral articular surface on the palmar side of manual phalanx I-1, and proximally compressed metatarsals III and IV.
