Contrasting Early Ordovician assembly patterns highlight the complex initial stages of the Ordovician Radiation [PDF]
Scientific Reports, 2022 The Early Ordovician is a key interval for our understanding of the evolution of life on Earth as it lays at the transition between the Cambrian Explosion and the Ordovician Radiation and because the fossil record of the late Cambrian is scarce.

The tarphyceratid cephalopod Trocholites in the Middle–Upper Ordovician of the Prague Basin —the Baltican element in peri-Gondwana [PDF]
Acta Palaeontologica Polonica, 2023 The vast majority of cephalopods of the order Tarphyceratida are known from regions that were located at mid- or low palaeolatitudes during the Ordovician (mainly Baltica, Laurentia, and Chinese palaeoblocks).

The Late Ordovician extinction conundrum [PDF]
Estonian Journal of Earth Sciences, 2023 The Late Ordovician mass extinction (LOME) has long been known for its association with the Hirnantian glaciations. Two extinction pulses seem to reflect global cooling and warming, respectively. The effects climate change had on Ordovician life are well

Was there more space in the late Early Devonian for marine biodiversity to peak than in the early Late Ordovician?: A brief note [PDF]
Geološki Anali Balkanskoga Poluostrva, 2013 After the so-called “Cambrian explosion”, marine biodiversity peaked either in the early Late Ordovician (as shown by the “classical” curves based on the extensive palaeontological data compilation) or in the late Early Devonian (as shown by the

Lower Palaeozoic source rocks in Manjiaer Sag, Tarim Basin
Petroleum Exploration and Development, 2008 Considering its vertical distribution characteristics, this article argues that the Lower Palaeozoic source rock in the Manjieer Sag is composed of three sets of source rocks of Middle-Lower Cambrian, Middle-Lower Ordovician, and Upper Ordovician.

Mercury spikes suggest volcanic driver of the Ordovician-Silurian mass extinction
Scientific Reports, 2017 The second largest Phanerozoic mass extinction occurred at the Ordovician-Silurian (O-S) boundary. However, unlike the other major mass extinction events, the driver for the O-S extinction remains uncertain.
