Abstract

The horizontal didymograptid speciesDidymograptus (Expansograptus) suecicus Tullberg,D. (E.) holmi Törnquist andD. (E.) similis (J. Hall) are redescribed using the type material and additional specimens. Their exact proximal structures are revealed for the first time from relief material. All three species can easily be differentiated taxonomically and also show differences in their biostratigrapnic distribution.

Kurzfassung

Die horizontalen DidymograptenDidymograptus (Expansograptus) suecicus Tullberg,D. (E.) holmi Törnquist undD. (E.) similis (J. Hall) werden nach dem Typenmaterial und zusätzlichen Exemplaren neu beschrieben. Die Arten lassen sich durch ihre Proximalstrukturen differenzieren und zeigen eine unterschiedliche biostratigraphische Verbreitung.
