The insect fossils recorded in the lithographic limestones of the Crato Formation (Aptian of
the Araripe Basin, Brazil) have a high degree of morphological fidelity of external and …

In the absence of complex, bioturbating organisms, the seafloor during the Precambrian was
covered in widespread organic matgrounds. The greatest diversity and complexity of organic …

This field and laboratory study examines whether regularly patterned biofilms on present‐
day intertidal flats are equivalent to microbially induced bedforms found in geological …

Micro‐organisms producing microbially induced sedimentary structures, particularly
epibenthic cyanobacteria, are not facies‐dependent and could flourish in any environment if …

Biogenic signatures in Precambrian rocks are often difficult to confirm and debatable. We
present some unusual features associated with microbial-mat related structures (MRS) from …

This study presents a review of the wide spectrum of biotic signatures within the
Precambrian Vindhyan Supergroup deposited during the 'boring billion'and assesses their …

The well-preserved limestone succession, Loma Negra Formation (~ 40 m), in the Tandilia
System was deposited in a shallow carbonate ramp under low energy conditions. The …

Abstract The 2.1‐billion‐year‐old (Ga) Francevillian series in Gabon hosts some of the
oldest reported macroscopic fossils of various sizes and shapes, stimulating new debates on …

ABSTRACT A category of wrinkle structures, often termed Kinneyia structure or Runzel
marks, comprises bedding plane features consisting typically of anastomosing, low-relief, flat …

The Vindhyan Basin is one of the largest intracratonic sedimentary basins of the world (Fig.
1.1). The basin has been studied for more than a century since the time of Oldham (1856) …
