Elizabeth Sibert

Elizabeth Sibert

Post-Doctoral Fellow
Knoll - Pierce - Lauder Groups
Junior Fellow of the Society of Fellows

Elizabeth is both a paleontologist and biological oceanographer. She is broadly interested in the evolution, structure, and function of ocean ecosystems. She uses a multi-proxy approach to study how the open ocean ecosystem has changed through time, with a focus on how it has responded to climate and biotic events in the past. Elizabeth works primarily with ichthyoliths, microfossil fish teeth and shark scales found in deep-sea sediments world wide, which preserve an unparalleled record of fish diversity, abundance, and community structure through geologic time.

Geobiology Seminar: "Mechanisms of the calcification response to ocean change"

12:30pm to 1:30pm

Location: 

Haller Hall (Geology Museum 102)

Speaker: Christina Frieder (USC)

Abstract:

Interactions between organic and inorganic processes are fundamental to development and growth. The initiation of shell formation in extant shelled molluscs appears to be an evolutionarily conserved process. Nevertheless, the physiology that coordinates biomineralization can be hindered by adverse environmental conditions, during which shells also retain environmental information that can...

Paleobiology Seminar: "Dating Microbial Phylogeny Using Horizontal Gene Transfer and Meta-Alignments"

12:30pm to 1:30pm

Location: 

Haller Hall (Geology Museum 102)

Speaker: Greg Fournier (MIT)

Abstract:

Date calibrations for applying molecular clocks to phylogeny are typically provided by fossil or other geologically preserved evidence.  However, for the vast majority of the Tree of Life, no fossil record exists.  While the paleontological record of lipid biomarkers and microbial microfossils provides some information, these records are extremely sparse, and often ambiguous. ...

Lecture with Andy Knoll

6:00pm to 8:00pm

Location: 

Geological Lecture Hall

Written in Stone: Reading Earth’s Library of Planetary History

Andrew H. Knoll, Fisher Professor of Natural History, Departments of Organismic and Evolutionary Biology, and Earth and Planetary Sciences, Harvard University

 

We live on a mature planet shaped by four billion years of evolution and environmental change. But what was Earth like in its youth and adolescence? To find out, Andrew Knoll travels to remote locations in search of rocks...
