- •
A new Silurian climate record is based on conodont apatite δ18Ophos compositions.
- •
Laurentian Canadian Arctic and Baltic records show near-synchronous cyclic trends.
- •
Two major cooling transitions had similar magnitude (+ 2‰) and duration (~ 1.5 Myrs).
- •
Faunal, eustatic and isotope records from disparate sites suggest key role of climate.
- •
Silurian climates were warmer than today with reef growth in cooler intervals.
