Exceptionally preserved fossils are the product of complex interplays of biological and
geological processes including burial, autolysis and microbial decay, authigenic …

Bacteria play an important role in the fossilization of soft tissues; their metabolic activities
drive the destruction of the tissues and also strongly influence mineralization. Some …

The oldest animals appear in the fossil record among Ediacara biota communities. They
prelude animal-dominated ecosystems of the Phanerozoic and may hold clues to the …

Abstract The Crato Formation paleoentomofauna is noticeable for its high abundance,
diversity and morphological fidelity, so the preservational approach of the Ephemeroptera …

The fossil record of the terminal Ediacaran Period is typified by the iconic index fossil
Cloudina and its relatives. These tube-dwellers are presumed to be primitive metazoans, but …

Ecdysozoans (Phyla Arthropoda, Kinorhyncha, Loricifera, Nematoda, Nematomorpha,
Onychophora, Priapulida, Tardigrada) are invertebrates bearing a tough, periodically …

Global biodiversity patterns in deep time can only be understood fully when the relative
preservation potential of each clade is known. The relative preservation potential of marine …

Panarthropoda, the clade comprising the phyla Onychophora, Tardigrada and
Euarthropoda, encompasses the largest majority of animal biodiversity. The relationships …

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 …

Trilobites with appendages from the Rust Formation of New York State were discovered in
the 1870s and represent one of the earliest known cases of exceptional preservation of non …
