| Abstract: | The new species of stegodon is now considered by authors to be a transitional form between gomphotherid mastodonts, Rulengchia and stegodontoid elephants,or an ancestral form of the latter. So both Stegolophodon and Rulengchia may be regarded as the ancestors of Stegodon by a relaying-cladogram with a method of characteristic analysis. Huaihe River transitional province may be the cradle of genus Stegodon (even genus Stegolophodon). |
