Plant Stem Fossils fossil crinoids, such as Pentacrinites, seem to have lived attached to floating driftwood and complete colonies are often found. Sometimes this driftwood would become waterlogged and sink to the bottom, taking the attached crinoids with it. The stem of Pentacrinites can be several metres long.
Frozen in time: fossil plant stem cells. The anatomy of ancient roots pushes the boundaries of palaeobiology, pointing to more diverse root biology than previously understood
Paleobotany. Plant fossils can be preserved in a variety of ways, each of which can give different types of information about the original parent plant. These modes of preservation are discussed in the general pages on fossils but may be summarised in a palaeobotanical context as follows.
