Some areas of the world are specially robust indinosaur fossil , and while some uncovering are spectacular or of particularscientific importance , some are just downright confusing . A new discovery in Mongolia fits into the latter class , with an unusual fossil of a theropod dinosaur deal that has some odd features .
At the Pigeon Hill site , of Morin Dawa Daur Autonomous Banner , Hulunbuir City , Inner Mongolia Autonomous Region , China , a enquiry team have discovered unexampled material belonging to a small - bodied theropod dino , including a complete paw , some ribs , and part of a tree branch .
The fossil is think to be around 121 million age old , from the time of the Early Cretaceous . owe to the strange body structure present within the bridge player the team call up this is a brand new species , and have key out itMigmanychion laiyang . Currently , they suggest that the fogey is part of the coelurosaurian clade Maniraptora , which finally evolve into the ascendant of modern raspberry .

The social system of the hand is different from all other experience specie of theropod , collapse rise to the interrogative of where this new species meet in . The sizing in world-wide , as well as the ossified carpometacarpus , show a absolved difference from other avialian fossils found in the same area .
Oviraptorosaurs , have it away for their feathers and similarities to birds , and therizinosaurs do have some structural similarities – as certify by previously get hold fossil – to the unexampled theropod fossil .
The unusual nature of the new fossil also conduct a resemblance to another fossil finding discovered in Japan , Fukuivenator paradoxus . The squad emphasize that this initial compartmentalization placement is tentative and design to keep look for more fossils to better discover where this new species fits into the dinosaur taxonomy .
The study is published inCretaceous Research .
