The dinosaur of the day: Unenlagia
- Dromaeosaurid theropod that lived within the Late Cretaceous in what’s now South America
- Solely leg size is thought, so not clear how lengthy Unenlagia was. Estimates are anyplace from 6.6 ft (2 m) to 11 ft (3.5 m) lengthy and weighing 165 lb (75 kg)
- Most likely had an elongated head, primarily based on family members Buitreraptor and Austroraptor
- Pelvic area was much like Archaeopteryx
- Initially thought the shoulder girdle was tailored for flapping, and that this confirmed flight began with flapping (nonetheless debating at this time) (flat scapula on high of the ribcage, so shoulder joint might level extra laterally), however in 2002 Kenneth Carpenter discovered that the scapula was most likely on the aspect of the ribcage
- Philip Senter prompt theropods like Unenlagia couldn’t elevate their forelimbs above their again
- Not everybody agrees, and a few scientists assume if the scapula was within the lateral place the coracoid bone would jut into the ribcage, which wouldn’t make sense
- Two species: Unenlagia comahuensis (sort) and Unenlagia paynemili
- Described by Fernando Novas and Pablo Puerta in 1997
- Genus title means “half chook” (in language of the indigenous Mapuche folks)
- Species title refers to Comahue, the area the place it was discovered
- Holotype features a partial skeleton, no cranium, however had vertebrae, sacrum, ribs, chevrons, scapula, humerus, partial pelvis, femur, tibia
- Second skeleton present in 2002, named and described in 2004 as Unenlagia paynemili
- Second species described by Jorge Calvo and others in 2004
- Discovered a holotype and a number of other paratypes
- Species title is in honor of Maximino Paynemil, chief of the Paynemil group
- Unenlagia paynemili is extra gracile than Unenlagia comahuensis
- Makovicky and others in 2005 discovered Neuquenraptor argentinus to be a junior synonym of Unenlagia comahuensis
- First theropod present in Argentina thought-about to be a dromaeosaurid
- Novas and Puerta thought-about Unenlagia to be a hyperlink between birds and maniraptoran theropods
