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'' .[1] Due to the substrate of the Myanmar borings being amber, the term 'amberground' was coined.
