- The mammalian adaptive radiation after the end-Cretaceous extinction is the pattern at evolutionary scale, with all four commitments cleanly substrate-driven.
This sourceDocuments the post-Cretaceous mammalian adaptive radiation into vacated niches and the closure as roles fill, reopening only after later extinctions.
Supported in partVerified against the publisher's abstract
Alroy's abstract documents a massive early Paleocene mammalian diversification immediately after the Cretaceous mass extinction, but says nothing about any 'four commitments' or a substrate-driven mechanism.
“Paleofaunal data confirm that there were fewer mammalian species during the latest Cretaceous than during any interval of the Cenozoic, and that a massive diversification took place during the early Paleocene, immediately after a mass extinction.”
- The mammalian adaptive radiation after the end-Cretaceous extinction is the pattern at evolutionary scale, with all four commitments cleanly substrate-driven.
Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
