Juvenile phacopid trilobites from the Prague Basin (Czech Republic)Paläontologische Zeitschrift - Tập 87 - Trang 219-234 - 2012

Complete early ontogenetic stages of phacopid trilobites are very rare in the
fossil record worldwide. Although phacopid trilobites were a common component of
the Devonian communities inhabiting the Prague Basin, only two articulated
juvenile individuals have been described so far. However, rich and diverse
fauna, including common remains of meraspid and young holaspid specimens of the
phacopid Pe... hiện toàn bộ
New species and structures in the Narthecoceratidae (Nautiloidea, Orthocerida)Paläontologische Zeitschrift - Tập 58 - Trang 79-87 - 1984
Rousseau H. Flower
In the NarthecoceratidaeFlower (1958) there is variation of structures within
the tubes of the endosiphuncle which may be empty, or may contain endocones or
“bracket diaphragms”,Winstonocera teicherti gen. et. sp. nov. shows numerous
diaphragms from which tubes extend a short distance forward. It is suggested
that the “bracket diaphragms” are similar structures. It is further suggested

Fossilien aus Riffkomplexen der alpinen Trias:Cheilosporites Wähner, eine Foraminifere?Paläontologische Zeitschrift - Tập 36 - Trang 118-124 - 1962
Alfred G. Fischer
The genusCheilosporites Wähner, a problematicum variously referred to algae and
sponges, is widespread in Rhaetian reefs of the Alpine region. Its arborescent
colonies are composed of uniserial but branching rows of chambers, penetrated by
an axial siphon. The chambers enlarge distally, and undergo marked changes in
shape. These characters are to be found neither among algae nor sponges, but are

Contribution of August Heinrich Ernst Beyrich to the knowledge of Ordovician trilobites in the Czech RepublicPaläontologische Zeitschrift - Tập 96 - Trang 669-687 - 2022
Oldřich Fatka, Petr Budil
The Barrandian area of the Teplá-Barrandian Unit is one of the richest
trilobite-yielding areas in the world. In the middle of the nineteenth century,
four main workers studied trilobites in this region, Joachim Barrande, Heinrich
Ernst Beyrich, Ignatz Hawle, and August Carl Joseph Corda. Heinrich Ernst
Beyrich, an excellent German palaeontologist studied and figured five species of
Ordovician tri... hiện toàn bộ
