New insights into Troglotella incrustans WERNLI & FOOKES, 1992, a fascinating Upper Jurassic-Upper Cretaceous foraminifer

New data about the highly variable test morphology of the benthic foraminifer Troglotella incrustans WERNLI & FOOKES (Oxfordian-Lower Cenomanian) are presented, permitting an emended species/genus diagnosis. This concerns mainly the existence of a large final chamber with fistulose extensions th...

This concerns mainly the existence of a large final chamber with fistulose extensions that may follow the uniserial or the irregular-branching test part. The way of life of T. incrustans (cryptoendolithic vs. euendolithic) is discussed against the background of different existing models in the literature.
