Shixinggia is a theropod dinosaur within the oviraptorosauria from the Late Cretaceous of China .
The only known species ( type species ), Shixinggia oblita , of this genus was first described in 2005 . Although few bones have been found, Shixinggia, like other oviraptorosaurs , is believed to have a short tail and a deep, toothless jaw that was shaped into a beak. Presumably it was herbivorous or omnivorous .
Find and naming
The only find so far ( holotype , catalog number BPV-112) was discovered in 1995 in Shixing County in the Chinese province of Guangdong . The fossils are dated to the late Upper Cretaceous ( Maastrichtian ) and come stratigraphically from the Pingling Formation .
Found the almost complete sacrum , wherein three rear vertebrae and three front caudal vertebrae were discovered in the natural anatomical composite, two incomplete ribs, both iliac bones (Ilia), parts of the thigh bone (femur), tibia (tibia), fibula (fibula) and the fourth phalanx.
The name Shixinggia refers to the Shixing district where the fossils were discovered. The Artepitheth oblita comes from Latin and means something like "neglected". The fossils were first described and named by Lu in 2004, the official description by Lu and Zhang followed in 2005.
features
Shixinggia is distinguished from other genera by features ( autapomorphies ) on the pelvic and leg bones: For example, the iliac bone is quite high in relation to its length, and the femur and the shinbone have large openings that are not known from any other oviraptorosaur.
