First plants cooled the Ordovician by Lenton, T, Lenton, T, Crouch, M, Crouch, M, Johnson, M, Pires, N, Pires, N, Dolan, L, Dolan, L

The Ordovician acritarch genus Coryphidium by Servais, T, Li, J, Molyneux, S, Vecoli, M

“…The review indicates that the genus first appears in the uppermost Tremadocian Araneograptus murrayi graptolite Biozone and is common through the upper Lower Ordovician and the Middle Ordovician, while Upper Ordovician occurrences might be the result of reworking. …”

A Cambrian–Ordovician Terrestrialization of Arachnids by Jesus Lozano-Fernandez, Jesus Lozano-Fernandez, Alastair R. Tanner, Mark N. Puttick, Jakob Vinther, Jakob Vinther, Gregory D. Edgecombe, Davide Pisani, Davide Pisani

“…Molecular dating on a phylogenomic tree that recovers arachnid monophyly, constrained by 27 rigorously vetted fossil calibrations, estimates that Arachnida originated during the Cambrian or Ordovician. After the common ancestor colonized the land, the main lineages appear to have rapidly radiated in the Cambrian–Ordovician boundary interval, coinciding with high rates of molecular evolution. …”

On future directions of Ordovician chitinozoan research by Yan Liang, Olle Hints, Jaak Nõlvak, Peng Tang

“…Due to their biostratigraphic utility, chitinozoans were intensively studied from the 1960s to the 1980s, and they have an important place in Ordovician stratigraphy nowadays, alongside graptolites and conodonts. …”

Ordovician paleogeography and the evolution of the lapetus ocean by MacNiocaill, C, vanderPluijm, B, VanderVoo, R

“…Paleomagnetic data from northern Appalachian terranes identify several arcs within the lapetus ocean in the Early to Middle Ordovician, including a peri-Laurentian arc at ∼10°-20°S, a peri-Avalonian arc at ∼50°-60°S, and an intra-oceanic arc (called the Exploits arc) at ∼30°S. …”

Cosmopolitan arthropod zooplankton in the Ordovician seas by Vannier, J, Racheboeuf, P, Brussa, E, Williams, M, Rushton, A, Servais, T, Siveter, D

“…Evidence is presented here for a zooplanktonic component in Ordovician marine ecosystems, namely the caryocaridid arthropods, that add to other well-documented midwater organisms such as graptolites, cyclopygid and telephinid trilobites, orthoconic cephalopods and the microphytoplankton (e.g. acritarchs). …”
