Bryozoan‐rich stromatolites (bryostromatolites) from the Silurian of Gotland and their relation to climate‐related perturbations of the global carbon cycle
(
- Sedimentology
, 2021-05-12)
Bryozoan–stromatolite associations (bryostromatolites) formed conspicuous reef structures throughout the Sheinwoodian (Wenlock) to Ludfordian (Ludlow) stratigraphy on Gotland but have not been described so far. They are ...
A rapidly evolving secretome builds and patterns a sea shell
(
- BMC Biology
, 2006)
Background: Instructions to fabricate mineralized structures with distinct nanoscale architectures, such as seashells and coral and vertebrate skeletons, are encoded in the genomes of a wide variety of animals. In mollusks, ...
Revisiting global trends in freshwater insect biodiversity: A reply
(
- Wiley Interdisciplinary Reviews: Water
, 2020-12-31)
Jähnig et al. make some useful points regarding the conclusions that can be drawn from our meta‐analysis; however, some issues require clarification. First, we never suggested that there was a globally increasing trend of ...
Coralline demosponges ; a geobiological portrait
(
- Bulletin / The Tohoku University Museum
, 2001)
The polyphyletic coralline demosponges possess a calcareous basal skeleton of 4 major
morphotypes. Each has its own phylogenetic history, with different mechanisms of formation. One
extant taxon of each skeletal type has ...
Comparing surface digitization techniques in palaeontology using visual perceptual metrics and distance computations between 3D meshes
(
- Palaeontology
, 2021-01-17)
The use of surface digitization techniques and methods in palaeontology has increased in the last two decades, mainly due to recent improvements in devices and software. However, many digitization efforts are published ...
Monophyly of the Porifera
(
- Verhandlungen des Naturwissenschaftlichen Vereins in Hamburg
, 1996)
The monophyly of the Porifera is weil established. According to our hypothesis the Hexactinellida
are the adelphotaxon of the Pinacophora (new taxon = Calcarea + Homoscleromorpha + Demospongiae).
The Porifera are the ...
Coleoids from the Lower Devonian Black Slate ("Hunsrück-Schiefer") of the Hunsrück (West Germany)
(
- Neues Jahrbuch für Geologie und Paläontologie. Abhandlungen
, 1983)
Three new genera of endocochleate cephalopods from the Lower
Devonian cast new light on the evolution of modern and fos sil coleoids. Protoaulacoceras
n. g. represents the r03trum-bearing line of aulacocerid-belemnitid ...
Die Embryonalentwicklung von Hibolithes (Belemnitida, Cephalopoda)
(
- Neues Jahrbuch für Geologie und Paläontologie
, 1984)
A study of unaltered minera·l shell la yers, the reconstruction of the
organic layers and a comparison with the embryonic shells of other shell-bearing
cephalopods indicate that the young Hibolithes hatching from the egg ...
Characterization on organic matrix proteins enclosed in high Mg-calcite crystals of the coralline sponge Spirastrella (Acanthochaetetes) wellsi

Understanding the geobiology of the terminal Ediacaran Khatyspyt Lagerstätte (Arctic Siberia, Russia)
(
- Geobiology
, 2020)
The Khatyspyt Lagerstätte (~544 Ma, Russia) provides a valuable window into late Ediacaran Avalon-type ecosystems with rangeomorphs, arboreomorphs, and mega-algae. Here, we tackle the geobiology of this Lagerstätte by the ...
