The dinosaur of the day: Sinusonasus
- Troodontid theropod that lived within the Early Cretaceous in what’s now Liaoning Province, China (Yixian Formation)
- Seems chook like, with elongated head and sickle claws on the second toes
- Not the identical as Sinosaurus, a theropod that lived within the Early Jurassic in what’s now Yunnan Province, China (Lufeng Formation)
- Kind species is Sinusonasus magnodens
- Described by Xu Xing and Wang Xiaolin in 2004
- Genus identify means “wave nostril”
- From a facet view, the nasal bones seem like a sine wave (curvy, rises and falls)
- Species identify means “large toothed”
- Had giant enamel
- Entrance enamel weren’t serrated
- Carnivorous
- Small, Gregory Paul estimated in 2010 Sinusonasus was about 3 ft (1 m) lengthy and weighed about 5.5 lb (2.5 kg)
- Different estimates that it weighed 22 lb (10 kg)
- Might have had feathers, based mostly on kinfolk present in the identical formation having feathers
- Holotype, IVPP V 11527, is a partial skeleton with cranium and fragments of the decrease jaw, partial tail, pelvis, and hindlimbs
- Holotype was partially articulated, and compressed
- Had transitional anatomical options, with a extra basal cranium and extra derived pelvis and hindlimbs
- Had proportionately giant openings of the nasal cavity that prolonged posteriorly (within the again)
- Had a protracted decrease leg, and foot was “arctometatarsal” (center a part of the center metatarsal was pinched between the encircling metatarsals), so most likely a very good runner
- Femur is about 5.5 in (14 cm) lengthy
- Had a protracted neck of the thighbone (between the femoral head and shaft)
- Had a comparatively brief head, which was about 77% the size of the thighbone
- From a facet view, had an additional opening (fenestrae) within the entrance outer facet of the higher jaw
- Tail most likely had about 30 vertebrae
- The chevrons (bony arch on tail vertebrae) on the finish of the tail had been very lengthy, and would have match collectively to kind a plate on the underside/underside of the tail
- Tail might have helped counterbalance and helped whereas working
- Thought to return from speedy evolutionary change from a gaggle that originated within the Cretaceous (not from troodontids creating earlier within the Jurassic than beforehand thought)
- Might present chance of modular evolution in troodontids (sure components developed)
Enjoyable Reality:
Shanshanosaurus is to Tarbosaurus, as Nanotyrannus is to Tyrannosaurus.
