Ep. 462 - Resurrecting an Ancient Toilet Brush Tree

February 25, 2024

Fossil hunting is like playing the lottery, your odds of hitting big are infinitesimal, but it can happen. Such was the case for Dr. Bob Gastaldo and colleagues when they unearthed the remains of Sanfordiacaulis densifolia, an extinct tree from the Carboniferous Period unlike anything we have ever seen. Join me and Dr. Gastaldo as we take a deep dive into why this tree is so strange and what it can tell us about an ancient ecology.

Ep. 406 - Reconstructing Ancient Plants

January 29, 2023

What does it take to reconstruct a plant that went extinct hundreds of millions of years ago? How do you find the right context to place it in when so much has changed? These are just some of the questions we explore in this episode. Dr. Jeff Benca returns to the podcast to talk to us about how he approaches paleobotanical reconstruction both as a scientist and an artist.

Ep. 403 - Fossil Bryophytes Revisited

January 8, 2023

The odds of any living material becoming fossilized are extremely rare, especially if that living thing is a moss, liverwort, or hornwort. It does happen, however, and my guest today is dedicating his career to studying and understanding what bryophyte fossils can tell us. We revisit a conversation with Alex Bippus, who at the time was a PhD student at Oregon State, to learn about his fascinating work studying fossilized bryophytes. From climate change to evolution, there seems to be no end to the fun of studying bryophyte fossils. This episode was produced in part by Paul, Karen, Randi, Caelan, Tom, Don, Susan, Corbin, Keena, Robin, Peter, Whitney, Kenned, Margaret, Daniel, Karen, David, Earl, Jocelyn, Gary, Krysta, Elizabeth, Southern California Carnivorous Plant Enthusiasts, Pattypollinators, Peter, Judson, Ella, Alex, Dan, Pamela, Peter, Andrea, Nathan, Karyn, Michelle, Jillian, Chellie, Linda, Laura, Miz Holly, Christie, Carlos, Paleo Fern, Levi, Sylvia, Lanny, Ben, Lily, Craig, Sarah, Lor, Monika, Brandon, Jeremy, Suzanne, Kristina, Christine, Silas, Michael, Aristia, Felicidad, Lauren, Danielle, Allie, Jeffrey, Amanda, Tommy, Marcel, C Leigh, Karma, Shelby, Christopher, Alvin, Arek, Chellie, Dani, Paul, Dani, Tara, Elly, Colleen, Natalie, Nathan, Ario, Laura, Cari, Margaret, Mary, Connor, Nathan, Jan, Jerome, Brian, Azomonas, Ellie, University Greens, Joseph, Melody, Patricia, Matthew, Garrett, John, Ashley, Cathrine, Melvin, OrangeJulian, Porter, Jules, Griff, Joan, Megan, Marabeth, Les, Ali, Southside Plants, Keiko, Robert, Bryce, Wilma, Amanda, Helen, Mikey, Michelle, German, Joerg, Cathy, Tate, Steve, Kae, Carole, Mr. Keith Santner, Lynn, Aaron, Sara, Kenned, Brett, Jocelyn, Ethan, Sheryl, Runaway Goldfish, Ryan, Chris, Alana, Rachel, Joanna, Lori, Paul, Griff, Matthew, Bobby, Vaibhav, Steven, Joseph, Brandon, Liam, Hall, Jared, Brandon, Christina, Carly, Kazys, Stephen, Katherine, Mohsin Kazmi Takes Pictures, Manny, doeg, Daniel, Tim, Philip, Tim, Lisa, Brodie, Bendix, Irene, holly, Sara, and Margie.

Ep. 324 - Palms Through Deep Time

July 4, 2021

Palms (Arecaceae) are among the best known and easily recognizable groups of plants on Earth. Their diversity is staggering and they play important roles in the ecology of the habitats in which they grow. But how much do we know about their evolutionary history? What can a deep time perspective teach us about palm evolution. Joining us to talk about this is paleobotanist Dr. Kelly Matsunaga. Dr. Matsunaga uses the palm fossil record to investigate a variety of palm-related topics from the evolutionary origins of modern palm diversity to the origins of tropical rainforests. This episode was produced in part by Amanda, Tommy, Marcel, C Leigh, Karma, Shelby, Christopher, Alvin, Arek, Chellie, Dani, Paul, Dani, Tara, Elly, Colleen, Natalie, Nathan, Ario, Laura, Cari, Margaret, Mary, Connor, Nathan, Jan, Jerome, Brian, Azomonas, Ellie, University Greens, Joseph, Melody, Patricia, Matthew, Garrett, John, Ashley, Cathrine, Melvin, OrangeJulian, Porter, Jules, Griff, Joan, Megan, Marabeth, Les, Ali, Southside Plants, Keiko, Robert, Bryce, Wilma, Amanda, Helen, Mikey, Michelle, German, Joerg, Cathy, Tate, Steve, Kae, Carole, Mr. Keith Santner, Lynn, Aaron, Sara, Kenned, Brett, Jocelyn, Ethan, Sheryl, Runaway Goldfish, Ryan, Chris, Alana, Rachel, Joanna, Lori, Paul, Griff, Matthew, Bobby, Vaibhav, Steven, Joseph, Brandon, Liam, Hall, Jared, Brandon, Christina, Carly, Kazys, Stephen, Katherine, Mohsin Kazmi Takes Pictures, Manny, doeg, Daniel, Tim, Philip, Tim, Lisa, Brodie, Bendix, Irene, holly, Sara, and Margie.

Ep. 300 - Reconstructing a Cretaceous Flora

January 17, 2021

Imagine being able to travel back 120 million years to the Early Cretaceous and scoop up handfuls of the forest floor. The amount you would discover in that material would be mind blowing and, amazingly, this is essentially what my guest gets to do. Dr. Fabiany Herrera is a paleobotanist based at the Chicago Botanic Garden who is currently helping reconstruct the flora of an ancient Mongolian swamp. Mongolia is well known for its dinosaur fossils, but what Dr. Herrera and his colleagues are uncovering is amazingly preserved evidence of the ecosystem that once support them. From resolving relationships among extant gymnosperms to describing new taxa, there seems to be no end to the information packed away in these amazing fossils. Join us as we catch a glimpse of an Early Cretaceous flora. This work was funded by the National Science Foundation.

Ep. 244 - Ancient Homes in Fossil Leaves

December 22, 2019

Plants and arthropods have a long evolutionary history that involves plenty of interaction. If you know where to look, evidence of such history can be found in fossil plant remains. Today we are joined by PhD student, Gussie Maccracken who has discovered the oldest remains of one of the most common, yet poorly understood plant/animal mutualisms on our planet. Did you know that many flowering plants produce tiny homes in their leaves for mites? They do, and it looks like this relationship is very old and very important. Join us for a fascinating discussion about how paleontologists can use plant fossils to gain insights into so many aspects of the living world. This episode was produced in part by Shamora, Alana, Laura, Alice, Sarah, Rachel, Joanna, Griff, Philip, Paul, Matthew, Clark, Bobby, Kate, Steven, Brittney, McMansion Hell, Joey, Catherine, Brandon, Hall, Vegreville Creek and Wetlands Fund, Kevin, Oliver, John, Johansson, Christina, Jared, Hannah, Katy Pye, Brandon, Gwen, Carly, Stephen, Botanical Tours, Moonwort Studios, Liba, Mohsin Kazmi Takes Pictures, doeg, Clifton, Stephanie, Benjamin, Eli, Rachael, Plant By Design, Philip, Brent, Ron, Tim, Homestead Brooklyn, Brodie, Kevin, Sophia, Mark, Rens, Bendix, Irene, Holly, Caitlin, Manuel, Jennifer, Sara, and Margie.

Ep. 231 - The Amber Time Capsule

September 22, 2019

Today we get a look back in deep time with the help of the amber time capsule. Amber will be most familiar both for its use in jewelry but also for its role in the Jurassic Park series. However, amber is also a gold mine of scientific discovery. Amber contains within the remnants of long extinct ecosystems. From insects to plants, and even tiny bubbles of prehistoric atmosphere, there is no telling what the next chunk of amber is going to reveal. Join me as I sit down with the Director of Paleontology for the Prairie Research Institute, Dr. Sam Heads, to discuss his research on amber and the many treasures it contains. This episode was produced in part by Griff, Philip, Paul, Matthew, Clark, Bobby, Kate, Steven, Brittney, McMansion Hell, Joey, Catherine, Brandon, Hall, Vegreville Creek and Wetlands Fund, Kevin, Oliver, John, Johansson, Christina, Jared, Hannah, Katy Pye, Brandon, Gwen, Carly, Stephen, Botanical Tours, Moonwort Studios, Lisa, Liba, Lucas, Mohsin Kazmi Takes Pictures, doeg, Clifton, Stephanie, Benjamin, Eli, Rachael, Anthony, Plant By Design, Philip, Brent, Ron, Tim, Homestead Brooklyn, Brodie, Kevin, Sophia, Brian, Mark, Rens, Bendix, Irene, Holly, Caitlin, Manuel, Jennifer, Sara, and Margie.

Ep. 189 - When Palms Grew in Wyoming

December 2, 2018

Join Dr. Sarah Allen and me as we journey back in time to the Eocene. Earth was a very different planet some 49 million years ago. Though we may recognize some Eocene flora, the combination of various plant lineages would be enough to make your head spin. Earth was experiencing a warming period and the plants had responded accordingly. Tropical species like palms were thriving in places like Wyoming and giant relatives of the redwoods covered much of North America and Asia. What Dr. Allen and her colleagues are learning about Eocene plant communities is not only interesting in its own right, it is helping scientists understand how ecosystems may respond to climate change into the future. This episode was produced in part by Brandon, Gwen, Carly, Stephen, Botanical Tours, Moonwort Studios, Lisa, Liba, Lucas, Mohsin Kazmi Takes Pictures, doeg, Daniel, Clifton, Stephanie, Rachelle, Benjamin, Eli, Rachael, Anthony, Plant By Design, Philip, Brent, Ron, Tim, Homestead Brooklyn, Brodie, Kevin, Sophia, Brian, Mark, Rens, Bendix, Irene, Holly, Mountain Misery Farms, Caitlin, Manuel, Jennifer, Sara, and Margie.

Ep. 188 - On the Origin of Flowering Plants

November 25, 2018

Despite their dominance on the landscape today, figuring out exactly when flowering plants got their start has been a challenge facing paleobotanists since Darwin's time. This so-called "abominable mystery" is nonetheless fascinating to study and that is exactly what our guest today focuses on. Joining us is Dr. Nan Crystal Arens from Hobart and William Smith Colleges. Her work on angiosperms of the early Cretaceous has given us insights into the evolutionary pressures that may have led to the evolution of flowering plants as well as how these early angiosperms made their living in a landscape already vegetated by a preponderance of gymnosperms. If you care at all about the history of plants on this planet, this is one episode you do not want to miss!

Ep. 131 - Lycopsids: What An Ancient Lineage Can Teach Us About Extinction

October 22, 2017

If you're into growing plants and looking at fossils, then this is the interview for you! Joining us today is Jeff Benca, a grad student at UC Berkely who discovered a love for growing clubmosses and their relatives. It was this love that convinced him that we can learn a lot about the past by studying the present. Since then he has gained a deep understanding of not only the history of this amazing lineage but also what it can teach us about mass extinction events. This episode was produced in part by Allan, Irene, Clifton, Sebastian, Holly, Katherina, Shane, Amy, Caitlin, Rosanna, Mary Jane, Jennifer, Sarah, Christopher, Sienna & Garth, Troy, Margie, Laura, and Mark.
