Brachiopods from the Korytnica basin (Middle Miocene; Holy Cross Mountains, Poland)

Abstract

Within the brachiopod assemblage collected from the Korytnica basin (Middle Miocene) on the southern slopes of the Holy Cross Mountains, Central Poland, diverse species of the genera Lingula Bruguiere, Terebratula O. F. Müller, Argyrotheca Dall, and Megathiris d'Orbigny have been distinguished. Most of the species are represented by juvenile specimens, whilst the adults are subordinate. Consequently, it is suggested that the Korytnica basin to which the brachiopod larvae had been transported by currents, was an unfavourable environment for their further development.
