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)
recently been acknowledged as an additional layer of complexity, contributing further inconsistencies of our understanding of metazoan diversity in deep time. The Cambrian Haiyan Lagerstatte of Yunnan, China, examined in Chapter 2, preserves...
Taphonomic characteristics of fossils on the burgessshale-type spectrum
(University of Missouri--Columbia, 2018)
of diversity in the fossil record. In fact, only about 30% of modern marine benthic macroorganisms contain hard parts suitable for easy preservation (Johnson, 1964) and in the Phyllopod Bed of the Cambrian Burgess Shale, only about 14% of species or 2...
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...
