The Late Ordovician mass extinction event (LOME) has long been viewed as odd compared to other mass extinction events in Earth’s history. Contrary to nearly all other major extinction phases known from the fossil record it appears to be instigated by an ice age. A new study, however, shows that the LOME was probably governed by mechanisms like those seen during most other events—including global warming.
