A left P4, right M1 and partial mandible from two Spanish middle Miocene localities were analysed in a fossil-plus-living ursid matrix that recovers the sampled genus within Ailuropodinae.
Automated checks cover structure, identifiers, translations and links only; maintainer and external expert review are not complete.
Kretzoiarctos beatrix is bounded by Spanish dental specimens including holotype P4 MNCN-CSIC NV-2-42 within an approximately 11.8–11.2 Ma sample envelope; its ailuropodine placement does not make it a direct giant-panda ancestor or global family first.
claim:taxon:kretzoiarctos:fossil-rangeA published fossil-plus-living ursid morphology matrix recovers Kretzoiarctos within Ailuropodinae, but internal ailuropodine clades are unresolved in its majority-rule bootstrap tree.
claim:taxon:kretzoiarctos:taxonomyKretzoiarctos is represented in the study by Nombrevilla 2 and ACM/C6-Camí in Spain; these two Iberian localities do not demonstrate a secure centre of origin or a complete distribution.
claim:taxon:kretzoiarctos:biogeographyThe study identifies left P4 NV-2-42, right M1 NV-2-40 and partial mandible IPS 46473 with associated P4 as Kretzoiarctos material.
claim:taxon:kretzoiarctos:morphologyThe paper interprets dental features as a tendency toward a more herbivorous diet, but the dental sample does not directly observe feeding, habitat, locomotion or a population-wide ecological guild.
