Completing the loop of the Late Jurassic–Early Cretaceous true polar wander event
This page documents how this source is reused across Claim by Claim. A source can support, challenge, qualify or contextualize different claims; appearing here does not imply endorsement of every linked proposition.
Evidence roles describe what this source helps establish inside each Investigation. They are local to that use, not permanent labels attached to the publication itself.
2024 original palaeomagnetic study estimates about 12 degrees of Jurassic true polar wander over eight million years and subsequent return over six million years.
Per-source study access and uncertainty documented in B09 R02–R03; not independent direct verification of the overarching historical event.
Challenges
A documented large Jurassic true-polar-wander loop is reconstructed at about 1.5–1.6 degrees per million years, illustrating the geological timescale of large reorientation.
