Claim ledger
ecology · contested
Teleoceras ecology is locality- and species-dependent: Florida isotope data favor principally terrestrial populations, whereas the 11.86 Ma Ashfall T. major sample shows limited mobility and supports wet-habitat or semi-aquatic interpretation.
claim:taxon:teleocerastaxonomy · medium
Teleoceras is treated as a North American rhinocerotid genus, while the strongest Ashfall conclusions are restricted to T. major.
claim:taxon:teleoceras:taxonomyfossil-range · medium
The atlas displays a 12.5–10 Ma North American Clarendonian occurrence envelope for Teleoceras major, including the 11.86 ± 0.13 Ma Ashfall sample, rather than a global genus range.
claim:taxon:teleoceras:fossil-rangemorphology · medium
Teleoceras is characterized by shortened limb and foot bones and hypsodont molars; the Ashfall T. major sample is short-legged and barrel-bodied, while a universal small nasal horn is not asserted.
claim:taxon:teleoceras:morphologybiogeography · medium
The evidence profile represents North American Florida and Nebraska study populations rather than a complete occurrence map for Teleoceras.

A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
