奇蹄类的世界

Eocene brontotheres span small early species to rhinoceros-sized forms across North America and Asia, illustrating an extinct herbivore radiation rather than a modern analogue.

claim:taxon:brontotheriidae:ecology
02 · 34 Ma · 多样性

规则改变

Near the Eocene–Oligocene boundary, marine ice-growth steps and the regional Hampshire mammal sequence can be aligned, but turnover, hiatus and immigration remain distinct observations.

claim:event:eocene-oligocene-transition
03 · 12 Ma · 证据

替代之前的共存

Miocene Anchitherium, hipparionins and Teleoceras occupied different dietary niches whose evidence varies by lineage and locality; guild change was prolonged rather than instantaneous.
