[dinosaur] Tongtianlong limosus

I don't recall seeing this mentioned on the list yet:

Cretaceous diversification of Asian oviraptorid dinosaurs: evidence from a new 
species preserved in an 
unusual posture" Nature Scientific Reports 6, Article number 35780.



Oviraptorosaurs are a bizarre group of bird-like theropod dinosaurs, the 
derived forms of which have 
shortened, toothless skulls, and which diverged from close relatives by 
developing peculiar feeding 
adaptations. Although once among the most mysterious of dinosaurs, 
oviraptorosaurs are becoming 
better understood with the discovery of many new fossils in Asia and North 
America. The Ganzhou 
area of southern China is emerging as a hotspot of oviraptorosaur discoveries, 
as over the past half 
decade five new monotypic genera have been found in the latest Cretaceous 
(Maastrichtian) deposits 
of this region. We here report a sixth diagnostic oviraptorosaur from Ganzhou, 
Tongtianlong limosus 
gen. et sp. nov., represented by a remarkably well-preserved specimen in an 
unusual splayed-limb 
and raised-head posture. Tongtianlong is a derived oviraptorid oviraptorosaur, 
differentiated from 
other species by its unique dome-like skull roof, highly convex premaxilla, and 
other features of the 
skull. The large number of oviraptorosaurs from Ganzhou, which often differ in 
cranial morphologies 
related to feeding, document an evolutionary radiation of these dinosaurs 
during the very latest 
Cretaceous of Asia, which helped establish one of the last diverse dinosaur 
faunas before the end-
Cretaceous extinction.
