- •
Development of tools for determining the sources of rare earth elements (REE) in conodont apatite
- •
Diagenetic uptake of REEs by conodonts occurs from shallow suboxic zone to deep burial zone
- •
Most conodonts in Ordovician strata of South China yield strongly lithogenous REE signatures
- •
Conodont apatite frequently does not preserve a recognizable hydrogenous REE signal
- •
Our findings suggest that many earlier studies of REEs in bioapatite will require re-evaluation
