Bonsoir ^^ alors voila depuis quelque temps je recherche des infos sur ces deux dinos ( car je compté faire une fiche sur eux) mais il semblerait que ces deux dinos n'en soi en faite qu'un seul .....
J'aimerais que vous m'éclairiez là dessus: Ces deux dinos font t'ils parmis de la même espece où sont ils deux genres bien différents ?

D'après Theropd database:
Kaijiangosaurus He, 1984
K. lini He, 1984
Bathonian-Callovian, Middle Jurassic
Xiashaximiao Formation, Sichuan, China
Holotype- (CCG 20020) seven cervical vertebrae
Referred- (CCG coll.) two dorsal vertebrae, seven caudal vertebrae, scapula, coracoid, humerus, proximal ulna, three metacarpals, three manual unguals, proximal tibia, proximal fibula, metatarsal II, partial phalanx II-1, phalanx II-2, pedal ungual II, partial metatarsal III (315 mm), partial phalanx III-2, phalanx III-3, pedal ungual III, incomplete metatarsal IV, phalanx IV-1, phalanx IV-2, phalanx IV-3, phalanx IV-4, pedal ungual IV
? (CCG coll.) jugal, teeth, femur (400 mm)
Comments- The material comes from at least two individuals, the femur being comparatively smaller than the other elements. It is possibly synonymous with Xuanhanosaurus, "Szechuanoraptor" and/or Gasosaurus.

Gasosaurus Dong and Tang, 1985
G. constructus Dong and Tang, 1985
Bathonian-Callovian, Middle Jurassic
Xiashaximiao Formation, Sichuan, China
Holotype- (IVPP V7264) four cervical vertebrae, seven dorsal vertebrae, (sacrum 279 mm) first sacral vertebra (68 mm), second sacral vertebra (59 mm), third sacral vertebra (41 mm), fourth sacral vertebra (52 mm), fifth sacral vertebra (63 mm), seven caudal vertebrae, humerus (237 mm), ilium (369 mm), pubis (332 mm), ischium (338 mm), femur (425 mm), tibia (370 mm), fibula, metatarsal II, metatarsal III
Paratype- ?(IVPP V7265) three teeth
Referred- material (Holtz, 2000)
Comments- Traditionally associated with megalosauroids, Holtz (2000) recently found it to be a basal coelurosaur in his analyses. This was based on the upturned femoral head, anterior trochanter cleft from the head, and proximal fibula being >75% the proximal tibial width. However, he also indicated new undescribed specimens suggest Gasosaurus is a carnosaur, perhaps a sinraptorid (Currie pers. comm. 1998 to Holtz). It is provisionally placed in that position here pending restudy.

Gasosaurus a l'air super interessant mais c'est vrai qu'il y a pas grand chose à montrer
