A possible chelonian egg from the Brazilian late cretaceous
13/13 checkable references clean · checked 2026-07-14
Every reference with a DOI in the deposited reference list resolved to a known work in Crossref or DataCite at the dated check, and none carried a publisher retraction, withdrawal, or removal notice.
24 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.
checked 2026-07-14 — re-checked daily as this page is visited; titles and statuses come from Crossref and DataCite and are not part of the signed record
