QuickCheck: Is the oldest known wooden structure made by non-humans?

THE field of archaeology is rife with buildings and artefacts that are considered to be the oldest. The oldest known stone structure (Göbekli Tepe, Turkiye - built around 9,000 BCE) the oldest known clay pot (found in Xianren cave in Jiangxi, China - around 20,000 years old) and the oldest known paved road (Lake Moeris Quarry Road, Egypt - about 2,500BCE) all have something in common, aside from being really old they were all made by humans.

Saying that, is it true that the oldest wooden structure on record was actually made by someone who was not human?
