Note figure 5: Eight journals with the biggest number of palynological articles over time.
"... Bibliometric analysis allows to distinguish different phases in the evolution of palynology
[...] the scientometric analysis of palynological documents suggests that in the second decade of the 20th century, the increasing trend of the number of published documents stopped. This tendency has been observed in most of the journals publishing palynological content. This may suggest that the discipline has reached its climax. Moreover, the last couple of years show a slow but constant drop in the number of published documents. During this period also a decrease in mean citation per document and per year is observed..."

"... Four types of occurrences account for a substantial number of fossil marine arthropods: (1) concretions, (2) clusters, (3) event beds, and (4) microbially sealed sediments. Understanding how these fossil associations developed shows that concentration deposits (Konzentrat-Lagerstätten) and conservation deposits (KonservatLagerstätten) are idealized concepts of fossil preservation, because Lagerstätten commonly incorporate aspects of both concentration and conservation ..."

They have often been named Asterophyllites grandis and Asterophyllites charaeformis in the past, but the use of these names is illegitimate for these species. In this study, these shoots have been assigned to five fossil species: Asterophyllites delicatulus, Asterophyllites parvulus, Asterophyllites gracilis, Asterophyllites taylorianum, and Asterophyllites lubnensis ..."
