Marine biodiversity increased markedly during the Ordovician Period (~ 487–443 million
years ago). Some intervals within the Ordovician were associated with unusually rapid and …

Abstract The Ordovician of Scandinavia (ie Denmark, Norway and Sweden) has been
investigated for over two centuries and, through time, various chronostratigraphic schemes …

The breakup of the L-chondrite parent body in the asteroid belt 466 million years (Ma) ago
still delivers almost a third of all meteorites falling on Earth. Our new extraterrestrial chromite …

The catastrophic disruption of the L chondrite parent body in the asteroid belt c. 470 Ma
initiated a prolonged meteorite bombardment of Earth that started in the Ordovician and …

Abstract The Middle Ordovician (Da**ian–middle Darriwilian)“orthoceratite limestone” is
documented in its traditional type area at Kinnekulle in the province of Västergötland in …

Marine red beds are usually interpreted as indicating water column oligotrophy, good bottom‐
water oxygenation and redox conditions. Lower Devonian successions of the Prague Basin …

We present the first reconstruction of the micrometeorite flux to Earth in the Silurian Period.
We searched 321 kg of condensed, marine limestone from the Late Silurian Cellon section …

Red colouring in marine red beds (MRB) is commonly attributed to deposition and early
diagenesis under specific redox conditions. Therefore, the MRB can be considered time …

The transition between the Volkhov and Kunda Baltoscandian stages (Darriwilian, Middle
Ordovician) is associated with a notable sea-level fall. This study documents the lithologic …

The Ordovician Period has emerged as a highly dynamic time in Earth history.
Comprehensive work on chrono, chemo and biostratigraphy has resulted in an overall …
