"... 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 ..."

"... A group of equisetalean shoots with distinctive small leaves occurs widely in the upper Bashkirian and lower Moscovian coal-bearing deposits of Euramerica. 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 ..."
