Summary
| Description |
English: Biogeographic statistics suggest that Gonkoken's ancestors arrived from North America (in purple). The alternative hypothesis that Gonkoken's ancestors could have dispersed from Europe into South America via Africa (Atlantogean hypothesis, in orange) was not supported by biogeographic statistics. Hadrosaurids related to the tribe Kritosaurini (in red) would also have dispersed from North America, giving rise to the clade Austrokritosauria in South America. These hadrosaurids may have never reached the same high latitudes as Gonkoken's ancestors, possibly because they arrived later in South America. Paleogeographic drawing is based on information from the PALEOMAP project of C. Scotese. |
