The dinosaur of the day: Elsornis
- Enantiornithine hen that lived within the Late Cretaceous in what’s now Mongolia (Djadokhta Formation)

- Some depictions appear to be a roadrunner
- Smaller than a roadrunner
- Walked on two legs, small, had a beak
- Discovered within the Gobi Desert
- Properly preserved, in three dimensions
- Solely a partial skeleton (no cranium) has been discovered, and it consists of each wings
- Has a pneumatized furcula (air stuffed cavities within the wishbone), which hadn’t actually been seen in enantiornitheans
- Had a bend or kink within the shoulder blade
- Within the arms, the ulna was brief in comparison with the humerus, and general the arms have been brief proportionally
- So the higher arm was for much longer than the decrease arm
- Proportions just like paleognaths, similar to ostriches and emus
- In all probability couldn’t fly, based mostly on its wing proportions
- First proof of a flightless enantiornithine
- Enantiornithes, “reverse birds” lived everywhere in the world through the Cretaceous (has been discovered on all continents besides Antarctica)
- Had claws on their wings and tooth
- However seemed so much like fashionable birds
- Over 80 species named of enantiornithes, although not all could also be legitimate (many named from a single bone)
- Elsornis is the one one discovered to date which will have been flightless
- One other enantiornithean, Flexomornis (named in 2010), had related options to Elsornis, however not sufficient of the arms discovered so in accordance with the authors who named Flexomornis, “such a declare is probably going untimely”
- Kind species is Elsornis keni
- Named in 2007 by Chiappe and others
- Genus title Elsornis means “sand hen”
- Species title keni is in honor of Ken Hayashibara, who supported the Hayashibara Museum of Pure Sciences–Mongolian Paleontological Heart Joint Paleontological Expedition
- Lived in a heat semi-arid local weather
- Different dinosaurs that lived across the identical time and place embody ankylosaurs similar to Pinacosaurus, dromaeosaurs similar to Velociraptor, halszkaraptorines similar to Mahakala, and ornithomimids similar to Aepyornithomimus
