Article: Ichnological nomenclature of clavate borings
The use of ichnoterminology for flask-shaped borings is reviewed. The names Gastrochaenolites Leymcrie and Teredolites Leymerie are recommended for use as ichnogenera for such borings in lithic and lignic substrates respectively. A range of morphology is recognized for each genus and the following new ichnospecies are described: G, ampullatus. G. cluniformis, G. dijugus, G. lapidicus. G, orbicularis, G. ornutus, G. torpedo, G. turbinatus, and T. longissimus, A key is given for rapid identification of the species, and stratigraphic distributions are given.
