Paleo botany.
On parle de milieu de sédimentation . Le poids des sédiments accumulés entraîne une compaction (par réduction de la taille des pores entre les grains) et parfois une cimentation des particules (lorsque l'espace intergranulaire est rempli par une précipitation chimique). Les particules consolidées forment une roche sédimentaire détritique.
One of the aspects of paleobotany which makes it unusual and interesting is that it is inherently interdisciplinary and can be approached from either a biological or a more geological perspective—or both together. Each perspective presents a variety of questions that are unique to that discipline. sible for the present low level of activity in Cretaceous megafossil paleo-botany. In the past decade a new method has been applied in Cretaceous paleo-botany which promises to shed light on the problems of angiosperm origin and evolution. This is the study of fossil pollen and spores. In contrastFaunai, floral and human remains have been analyzed by archaeozoology, paleo-botany and bioarchaeology specialists (Xiao 2014; Zhang et al. 2015; Merrett et al. 2015), and samples have been taken for ancient DNA, as well as carbon and nitrogen isotope analysis.

Eophytes are a recently described group of early land plants from the Welsh Borderland that help us understand the evolution of plants during the Silurian-Devonian (Edwards et al. 2021 a; Edwards et al. 2021 b). "Eo-phyte" means early plant, and they provide evidence of the transition from non-vascular plants (e.g.bryophytes), to plants that were evolving conducting cells.Paleobotany, also spelled as palaeobotany, is the branch of botany dealing with the recovery and identification of plant remains from geological contexts, and their use for the biological reconstruction of past environments (paleogeography), and the evolutionary history of plants, … See moreCredits and distribution permission.
