FEATHERED DINOSAURS
3 of 56 checkable references need attention · checked 2026-07-14
At the dated check, the references listed below either did not resolve in Crossref or DataCite, or carried a publisher retraction notice. Each one is shown with the registry record that put it there.
56 without a DOI — not checked. A reference deposited without a DOI is never matched by title or guessed at; it stays outside the checked set, and this line discloses that.

What this badge says. CiteStamped means the CHECKABLE references of this
work were clean at the dated check: each resolved to a known work in a public registry, and none
carried a publisher retraction notice at that time. It says nothing about the quality, findings,
or importance of the work itself, and nothing about references deposited without a DOI.
