On the margins: exceptionally preserved small carbonaceous fossils (SCFs) from Silurian marginal marine strata of southern China [PDF]
Acta Palaeontologica PolonicaSmall carbonaceous fossils (SCFs) have recently emerged as a novel means to track the evolution of non-mineralized animals throughout the early Palaeozoic. Currently however, records are largely concentrated in Cambrian-age strata, and little is known of

Trace fossils associated with Burgess Shale non-biomineralized carapaces: bringing taphonomic and ecological controls into focus [PDF]
Royal Society Open Science, 2019 The association of trace fossils and non-biomineralized carapaces has been reported from Cambrian Lagerstätten worldwide, but the abundance, ichnodiversity, taphonomy and ecological significance of such associations have yet to be fully investigated. Two

Exceptional Fossil Preservation and the Cambrian Explosion [PDF]
Integrative and Comparative Biology, 2003 Exceptionally preserved, non-biomineralizing fossils contribute importantly to resolving details of the Cambrian explosion, but little to its overall patterns. Six distinct "types" of exceptional preservation are identified for the terminal Proterozoic-Cambrian interval, each of which is dependent on particular taphonomic circumstances, typically ...

Orbital control on exceptional fossil preservation [PDF]
Geology, 2018 Exceptional fossil preservation is defined by the preservation of soft to lightly sclerotized organic tissues. The two most abundant types of soft-tissue preservation are carbonaceous compressions and replicates in authigenic minerals. In the geological record, exceptionally preserved soft fossils are rare and generally limited to only a few ...

Appendicular anatomy of the artiopod Emeraldella brutoni from the middle Cambrian (Drumian) of western Utah [PDF]
PeerJ, 2019 The non-biomineralized artiopod Emeraldella brutoni Stein, Church & Robison, from the middle Cambrian (Drumian) Wheeler Formation in Utah represents the only confirmed occurrence of the genus Emeraldella outside of the stratigraphically older (Wuliuan ...

Exceptional soft tissues preservation in a mummified frog-eating Eocene salamander [PDF]
PeerJ, 2017 Fossils are almost always represented by hard tissues but we present here the exceptional case of a three-dimensionally preserved specimen that was ‘mummified’ (likely between 40 and 34 million years ago) in a terrestrial karstic environment. This fossil

Beyond Eocene and Oligocene Epochs: The Causses du Quercy Geopark and the Grande Coupure [PDF]
Geoconservation Research, 2021 The "phosphatières du Quercy" are karstic fillings exploited for phosphate at the end of the 19th century. They yield countless continental fossils through some 30 million years, ranging from late early Eocene to early Miocene.

Bioimmuration: exceptional fossil preservation made routine [PDF]
The Paleontological Society Special Publications, 1992 Bioimmuration, broadly defined as fossilization by virtue of organic overgrowth, allows preservation of soft-bodied organisms and soft parts of organisms with mineralized skeletons. Sessile organisms attached to hard or firm substrates are routinely overgrown by other organisms competing for living space.

Environmental Factors Affecting Feather Taphonomy
Biology, 2022 The exceptional preservation of feathers in the fossil record has led to a better understanding of both phylogeny and evolution. Here we address factors that may have contributed to the preservation of feathers in ancient organisms using experimental ...
