The Wood Bay Series is a geologic formation found on the island of Spitsbergen, Svalbard in Norway. It preserves fossils dating back to the Pragian–Emsian stages of the Devonian period.{{Cite journal |last1=Pernègre |first1=V.N. |last2=Blieck |first2=A. |date=2016 |title=A revised heterostracan-based ichthyostratigraphy of the Wood Bay Formation (Lower Devonian, Spitsbergen), and correlation with Russian Arctic archipelagos |url=https://www.researchgate.net/publication/299477690 |journal=Geodiversitas |volume=38 |issue=1 |pages=5–20 |doi=10.5252/g2016n1a1|s2cid=55307211 }}
