Conchoraptor gracilis

Conchoraptor was a bit modest in the head crest department, which led Rinchen Barsbold to assume it was an infant Oviraptor, and that elaborate head decor would arrive with maturity. As it happens, the only confirmed remains of Oviraptor are so smashed its hard to tell if it had a crest, and Barsbold's specimen turned out to be a bona fide adult specimen of an all new genus that was later assigned to the Ingenia-anchored sub-family called Ingeniinae, but due diligence was sadly lacking.

Strictly speaking, the Ingeniinae name bearer should be Ingenia mirabilis — a bug that Gerlach christened a full 24 years earlier than Ingenia yanshini the dinosaur, and while the latter was waiting for a replacement name it was in no position to be anchoring anything. Recently, Jesse Easter rechristened the dinosaur Ajancingenia, but even this caused controversy as paleontological etiquette was ignored (coining authors get dibs if their dinosaur needs renaming), and on top of that much of the paperwork that came with it was allegedly "borrowed" from a third party without a sniff of due credit. Nevertheless, the name stands, but palaeontologists still use "Ingeniinae" (enclosed in quotes) which is understandable given the furore.

"Ingeniinae" is a subfamily within Oviraptoridae — a family of omnivorous theropod dinosaurs colloquially known as "egg snatchers" — whose members are renowned for their smooth, crestless noggins. Typically for this group, Conchoraptor is smaller than non-ingeniine oviraptorids, but its arms and legs are proportionately longer. Weight-saving holes riddle its skull, and CT scans of its braincase showed that Conchoraptor had sharp hearing, and good vision, balance, and coordination.
(Gracile Shellfish Plunderer)Etymology
Conchoraptor is a derived from the Greek "konkhe" (mussel, shellfish) and "raptor" (plunderer). Theoretically, its robust beak may have been especially suited to cracking the shells of edible marine gastropods, the remains of which were scattered throughout its fossil bed. The species epithet, gracilis, means "slender" in Latin.
Discovery
The remains of Conchoraptor were discovered in the Red Beds of Hermiin Tsav in Mongolia's Nemegt Formation by a Polish-Mongolian expedition in 1971.
The holotype (GI 100/20) is a partial skeleton and skull, lacking the lower jaw.
