Podcasts about geologic time

Dr. Scott Rowland has studied and taught geology at the University of Hawai‘i volcanologist for 47 years, having earned teaching distinctions including the Board of Regents and President's awards. He shares with us his research into remote-sensing volcanology to help determine the ages of different lava flows across the Hawaiian Islands. We also revisit the processes that caused the 2018 Kīlauea volcanic eruption which devastated homes, roads, beaches and harbors in Hawai‘i as well as several destructive Hawaiian earthquakes in the 19th and 20th century. Through his telling, we gain an extended sense of time from the formation of the Hawaiian archipelago 80+ million years ago to the present day.

Today on Mushroom Hour we have the privilege of being joined by Dr. Kevin Boyce, Professor of Geological Sciences at Stanford University. Dr. Boyce's research is focused on the biological and environmental impacts of the evolution of plant structure, development, and physiology from the Paleozoic colonization of land through the subsequent radiations of land plant forms up to and including the Cretaceous radiation of flowering plants. This work involves both living and fossil plants and a wide variety of approaches: developmental and physiological investigation, climate modeling, comparative study of morphological diversity, and cell and tissue-specific analysis of elemental, isotopic, and organic chemistry. These tools have been applied to three connected areas of research that each inform wider questions concerning the evolution of terrestrial environments: 1. the evolution of leaf morphology, development, and physiology with feedbacks to climate and primary productivity, 2. the evolution of cell wall biochemistry and its influence on organic matter burial as a sink in the carbon cycle, and 3. the establishment of early terrestrial life and ecosystems encompassing the complete biota including animals, fungi, and microbial communities in addition to the plants. I'm excited to learn about the coevolution of plants and fungi, prototaxites and how we learn about organismal evolution and community assembly from the ancient past.    TOPICS COVERED:   The Path into PaleontologyGeobiology & Defining Geological Eras   Fungal & Plant Fossil Records   Absolute Time & Relative Time   Evolution of Plant Physiology   Coevolution of Plants, Bacteria, Fungi and Animals   Stochastic "Rules" of Community Assembly   Geochemistry   Genetic Tools and Phylogeny Changing Paleontology   Prototaxites   Biochemical Signatures of Heretrophs and Autotrophs   Piecing Together a Paleozoic Landscape    Lifestyle, Physiology and Growth Rate of Prototaxites   Future Work into the Cenozoic   EPISODE RESOURCES:   Dr. Kevin Boyce Academic Website: https://biology.stanford.edu/people/kevin-boyce   Dr. Boyce Paper on Prototaxites: https://awarticles.s3.amazonaws.com/Boyce2007.pdf   Prototaxites: https://en.wikipedia.org/wiki/Prototaxites   Geologic Time Scale: https://en.wikipedia.org/wiki/Geologic_time_scale   "Wonderful Life" by Stephen Gould: https://wwnorton.com/books/Wonderful-Life/   Lycopodium (clubmoss genus): https://en.wikipedia.org/wiki/Lycopodium   "Stinkhorn" Mushrooms: https://www.mushroomexpert.com/stinkhorns.html

Matt, Sarah, and Doug discuss all things geologic time with KGS geologist and geomorphologist Jason Dortch (a lover of geologic time and our first repeat guest!) including the abstract concept itself, the geologic time scale, deep time, love/hate with the Anthropocene, geologic hazards and resiliency, and much more!

Part of our ability to date the rock sequences we see in the world and determine which are older and which younger has to do with simple observation. We see that older rocks contain trilobites and a wee bit above those we see ammonites, then clams and oysters in newer sediments. For a long time, this simple observation held us in good stead. We had a relative timescale for the Earth and this allowed us to piece together the biologic and geologic picture much clearer. To understand and date rock in absolute terms required advances in science, in chemistry in particular, that we achieved in large part by 1895. This was the beginning of our understanding of distinct elements and the periodic table of elements. To many, the table is a memory of science classes from our youth and long forgotten. But in the period table, we find both the tremendous history of human achievement and the aha moments that help us to understand simple yet complex concepts like radioisotope decay — the genius tool we use for the absolute dating of rocks and fossils. To that end, I highly recommend Sam Kean's book, The Disappearing Spoon. It is a tasty romp through madness, love and the history of the world through the eyes of the periodic table. You may find that within the stories that the table becomes more real for you and that the mysteries it holds are more easily within your grasp.

We live on an amazing planet with a 4.5 billion year history of life evolving from a single cell to multicellular life to the sheer volume of diversity of species we see through time and walking the Earth today. How do we know the timeline for this? How do we date the rock units and mountains and stones beneath our feet? We use simple observation out in the field to look at rock and observe that generally speaking, older rock units tend to be deeper than the younger rock on top. We use index fossils like ammonites or Triassic paperclams to help give us a better understanding. We also turn to chemistry and use the decay rates of radioisotopes to help give us a time stamp on a rock unit. We use Carbon-14 for rock younger than 50 thousand years or Potassium-40 or Uranium for rock older than 50 thousand years. It was through the decay rate of uranium that we arrived at a relative age of the Earth of 4.5 billion years. We have new techniques evolving out of various fields of science to help us gain a deeper understanding of the Earth. Donald Prothero has been taking deep-sea drilling cores which tell us of shifts in the magnetic field of the Earth. His work will let us date the fossils we find to within 100,000 years — a significant insight over the plus or minus 2-million-year dating that radioisotopes give us.

In this episode, the boys talk about the history of how the Paleozoic and Mesozoic Eras came about in the geologic time scale.

Nick grapples with the expanse of geologic time.

We are exploring fossils and how they allow us to compare past and current life on this planet, thow environments have changed, and provide important evidence that our tectonic plates have moved over time. We will eventually connect all of these concepts to the process of natural selection and how life on this planet has evolved, which we see in the fossil record and allows us to compare organisms and their connections.

Fossils and rocks have preserved an amazing story for us to uncover, as we look back into time using rocks and fossils as the guide. They show us how the Earth has changed as well as the the environment and life along with it. Our picture of Geologic Time allows use to compare living things to the past and observe their similarities and differences.

All about time travelling back to how earth was formed and how we ended up here today. Interesting food for thought and a mix of unecessary virtue signalling.
