Abstract

Abstract Turtles of the total Clade Pan-Chelidae have a relatively poor fossil record, which is completely restricted from the Early Cretaceous to Recent of South America and Australasia. The clade is expected to have formerly inhabited Antarctica as well. The phylogenetic relationships of extant pan-chelids remain poorly resolved, notably because there are conflicting signals between morphological and molecular data. The ecology of fossil pan-chelids appears to have been similar to that of their extant relatives. A taxonomic review of the group concluded that of 45 named taxa, 22 are nomina valida, 6 are nomina invalida and 15 are nomina dubia, whereas the final 2 are rendered non-testudinate through the designation of lectotypes.

泛龟科龟类化石记录综述

泛龟科总分支龟类化石记录相对较差，完全局限于早白垩世至最近的南美洲和澳大拉西亚。据估计，这支进化支以前也居住在南极洲。现存的泛螯虾的系统发育关系仍然没有得到很好的解决，特别是因为形态和分子数据之间存在冲突的信号。化石泛chelids的生态似乎与它们现存的近亲相似。对该类群的分类分析表明，45个已命名的分类群中，22个为名义有效分类群，6个为名义无效分类群，15个为名义可疑分类群，而最后2个通过指定选型而被认为是非无性分类群。
