Exempel på microfossil

• Unfortunately the title of the volume gives the impression that palynomorphs, which have organic walls, are not microfossils.

• The discussion on chemical procedures deals almost exclusively with the extraction of microfossils from different matrices.

• An integrated, multidisciplinary approach to this study is essential for the verification of any artefact purported as a microfossil.

• However, the interpretation of ancient microfossils found even in terrestrial sediments has been hotly debated for years.

• While many of the larger microfossils herein are similar in size to extant eukaryotic micro-algae, they cannot be regarded as unequivocally eukaryotic.

• Mineralized microfossils have typical dimensions significantly smaller than the resolution of any spacecraft instrument.

• Advantages of doubly polished thin sections for the study of microfossils in volcanic rock.

• After having read the book, nobody can doubt that microfossils should become a standard tool in future environmental studies.

• In petrographic thin sections cut perpendicular to the bedding, the microfossils appear only as very thin, dark streaks.

• However, it is still unclear how these processes affect the internal microstructure of such remains, or even how to recognize bona fide preserved microfossils.

• This allowed observation of opaque (carbonized) microfossils, and also assessment of the fossil nature of the isolated microstructures.

• The authors have succeeded in this as the book presents numerous case studies, which clearly demonstrate the unique applicability of these microfossils.

• The growing importance of microfossils for biosteering horizontal wells is not mentioned; however, this contribution is helpful as a teaching aid.

• Not all lakes possess sediment records that lend themselves to isotopic study using oxygen isotope ratios in carbonate microfossils.

• The details of the physical characteristics will have relevance when correlated with the pollen and microfossil analysis.
