Summary
| Description |
Congruence between Middle Jurassic sauropod distribution and paleoclimatic zones. Although standing close to the origin of Eusauropoda, Spinophorosaurus exhibits strong similarities to East Asian Middle Jurassic sauropods (Shunosaurus, 6), and much less so to South Gondwanan forms, e.g. the late Lower Jurassic Barapasaurus from India and the late Middle Jurassic form Patagosaurus (1). The explanation is a separation of global sauropod faunas during the Lower Jurassic by the Central Gondwanan Desert (CGD), forming two different paleobiogeographical domains. Neosauropods had their origin in the same climatic zone as Spinophorosaurus and gained global distribution in late Middle Jurassic times (Atlasaurus, 4; Bellusaurus, 6; Lapparentosaurus, 2; Tehuelchesaurus, 1). Map redrawn after [48] and [75]. Abbreviations: CT, cold temperate climate; WT, warm temperate climate; SW, summer-wet climate; WW, winter-wet climate. |
