Biomineralizers from the proterozoic to today : assessing taxonomy and paleoecology through the lens of taphonomy
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The onset of metazoan predation is presumed to have triggered an evolutionary arms race of prey defenses, including the advent of biomineralization. Escalating biological...
Preservation and bias in the Cambrian fossil record
(University of Missouri--Columbia, 2022)
Paleontology views deep time ecosystems through a taphonomic lens, biased and restricted by the controls enacted on each fossil deposit by various environmental factors, and including chemical and biological variables. ...
Assessing soft tissue preservation in a variety of saline Environments through actualistic decay experiments and an isotopic assessment of pyritized plant fossils from the Mazon Creek, IL
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Most taphonomic pathways for soft-tissue preservation require minerals either forming on the surface of or replacing tissues. Among various other factors, the rates at which...
Taphonomic characteristics of fossils on the burgessshale-type spectrum
(University of Missouri--Columbia, 2018)
"Study of exceptional fossil preservation tends to yield exciting results. Since soft-bodied organisms and the soft tissues of biomineralizing organisms are usually not preserved in the fossil record, instances of soft-tissue ...
