Teredolites

Teredolites is an ichnogenus of trace fossil, characterized by borings in substrates such as wood or amber.

Club-shaped structures rimming mid-Cretaceous Burmese amber were formerly identified as the fungal sporocarps Palaeoclavaria burmitis. A 2018 study re-identified the structures as domichnia (crypts) bored in the amber nodules by bivalves of the pholadid subfamily Martesiinae. The borings are comparable with Teredolites clavatus and Gastrochaenolites lapidicus. Due to the substrate of the Myanmar borings being amber, the term 'amberground' was coined.
