Isolated calcanei and tali from Shanghuang and Yuanqu were attributed to Eosimias and compared in a character matrix testing anthropoid affinity; they are not dentally associated skeletons, a direct ancestor, or a complete record of Eosimias anatomy.
Automated checks cover structure, identifiers, translations and links only; maintainer and external expert review are not complete.
Eosimias is bounded by isolated tarsals and dental comparisons from Chinese middle Eocene fissure fills and basins, approximately 45–40.5 Ma; the tarsals are not dentally associated, so the interval is not a secure global genus range or crown membership.
claim:taxon:eosimias:fossil-rangeGebo and colleagues attribute isolated Shanghuang and Yuanqu calcanei and tali to Eosimias and recover anthropoid affinity in their sampled character analysis; the bones are not dentally associated skeletons or demonstrated direct ancestors.
claim:taxon:eosimias:taxonomyThe profiled Eosimias tarsals come from the Shanghuang fissure fillings and Yuanqu Basin in China; these sampled localities do not establish a complete distribution for the genus.
claim:taxon:eosimias:biogeographyThe isolated Eosimias tarsals support anatomical comparison but do not directly record diet, habitual habitat, observed locomotion, population body size or ecological guild; these fields remain bounded or unresolved here.
claim:taxon:eosimias:ecologyThe Shanghuang and Yuanqu sample consists of isolated calcanei and tali with a mosaic of characters used in an anthropoid-affinity test; the study does not document a complete associated foot or dental-postcranial association.
