Taphonomy of Paleogene and Neogene vertebrate assemblages [PDF]

open access: yesThe Paleontological Society Special Publications, 1992
The Paleogene of Wyoming and Montana and the Neogene Siwaliks of Pakistan contain deposits representing a wide variety of terrestrial environments. Although fossils are preserved in all of these environments, fossil vertebrates are abundant in only certain facies.

Vertebrate taphonomy of the Ischigualasto Formation [PDF]

open access: yesJournal of Vertebrate Paleontology, 2012
ABSTRACT Trends of preservation are established on the basis of 385 fossil occurrences in the Ischigualasto Formation. The distribution and preservational quality of vertebrate fossils are related to sedimentary facies and stratigraphic position and follow trends in basin evolution and paleoclimate.

Site formation processes and the taphonomy of vertebrate remains in underwater caves

open access: yesEarth-Science Reviews
Palaeontological and zooarchaeological deposits have been recovered from underwater caves across the globe, but studies on site formation processes in these environments are scattered and have never been systematically examined. Flooded caves in the phreatic zone of karst systems include sinkholes and fensters (windows) that form a connection between ...

Sedimentology and vertebrate fossils of the Frasnian Ogre Formation, Gurova outcrops, eastern Latvia [PDF]

open access: yesEstonian Journal of Earth Sciences, 2020
Combined sedimentological and palaeontological study of the siliciclastic sequence of the Ogre Formation in the easternmost area of its distribution in Latvia was aimed at the facies analysis of the deposits and at detailed observation of the taxonomical

Experimental dissolution of fossil bone under variable pH conditions

open access: yesPLoS ONE, 2022
Fossils exposed at the surface are an integral component of the paleontologic record and provide an archive of past life. However, it is widely known that fossils are not stable indefinitely upon exposure to surface conditions such as physical, chemical,

A taxonomic and phylogenetic review of the anhanguerid pterosaur group Coloborhynchinae and the new clade Tropeognathinae [PDF]

open access: yesActa Palaeontologica Polonica, 2020
Anhanguerids are a particular group of pterodactyloid pterosaurs, characterized mainly by their rostral sagittal crests, well laterally expanded jaw tips and enlarged anterior teeth.

New occurrences of fossilized feathers: systematics and taphonomy of the Santana Formation of the Araripe Basin (Cretaceous), NE, Brazil [PDF]

open access: yesPeerJ, 2016
Here we describe three fossil feathers from the Early Cretaceous Santana Formation of the Araripe Basin, Brazil. Feathers are the most complex multiform vertebrate integuments; they perform different functions, occurring in both avian and non-avian ...
