Fitness and scope

morphology · taxonomy · topology · range · biogeography · ecology

Approximately 280 Dormaal specimens document dentition and tarsals; genus assignment and topology are morphology-based.

Claim ledger

morphology · high

The earliest-Eocene Dormaal sample includes nearly complete deciduous and permanent dental representation plus catalogued astragali and a calcaneum; the new-genus assignment and basal carnivoraform position are morphology-matrix interpretations rather than crown membership or direct ancestry.

claim:event:dormaalocyon-dental-tarsal-sample
taxonomy · medium

The Dormaal sample supports Dormaalocyon latouri and a basal carnivoraform placement in the published matrix; it is not promoted into crown Carnivora or direct ancestry.

claim:taxon:dormaalocyon:taxonomy
biogeography · medium

The profile is restricted to the Dormaal locality in Belgium and does not establish the complete early carnivoraform distribution.

claim:taxon:dormaalocyon:biogeography
ecology · medium

Dental and tarsal anatomy support small-faunivore and arboreal-capability inferences, while diet and habitual locomotion were not directly observed.

claim:taxon:dormaalocyon:ecology
morphology · medium

IRSNB M2095–M2099 document dentition and IRSNB M2107–M2109 document astragali and a calcaneum in the catalogued sample.

claim:taxon:dormaalocyon:morphology
fossil-range · medium

The 56–55.8 Ma envelope is the bounded Dormaal sample context, not a crown-Carnivora FAD, genus LAD or lineage duration.

claim:taxon:dormaalocyon:fossil-range
fossil-range · medium

The 56–0 Ma Carnivora route is a total-group evidence anthology: the Dormaal Carnivoraformes sample anchors the older bound and living crown carnivorans extend to the present; it is not a crown-Carnivora FAD or ancestor chain.
