Ep. 317 - Leaf Margins, Paleoclimates, and Continental Movements

Are the leaf margins smooth or toothed? How dense are the leaf veins? Are the petioles thick or thin? The answers to these questions go far beyond helping us identify plant species. Dr. Ian Miller of the Denver Museum of Nature and Science joins us to talk about how such details in leaf fossils can be used to understand everything from the climate of the Cretaceous to the movement of continents. You will be amazed at just how much information paleobotany can provide.This episode was produced in part by Arek, Chellie, Paul, Dani, Tara, Elly, Colleen, Natalie, Liam, Ario, Nathan, Laura, Cari, Laura, Kali, Margaret, Mary, Connor, Nathan, Jan, Jerome, Brian, Melody, Azomonas, Ellie, University Greens, Cynthia, John, Ashley, Peter, Cathrine, Melvin, OrangeJulian, Porter, Grif, Jules, Joan, Les, Marabeth, Ali, Margaret, Southside Plants, Robert, Keiko, Bryce, Brittany, Helen, Amanda, Mikey, Rhiannon, Michelle, Kate, German, Joerg, Alejandra, Cathy, Jordan, Judy, Steve, Kae, Carole, Mr. Keith Santner, Dana, Chloe, Aaron, Sara, Kenned, Vaibhav, Kendall, Christina, Brett, Jocelyn, Kathleen, Ethan, Kaylee, Runaway Goldfish, Ryan, Donica, Chris, 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. 316 - How an Asteroid Changed Neotropical Rainforests

The asteroid that slammed into the Yucatan Peninsula some 66 million years ago marked the end of the Cretaceous and the reign of the dinosaurs. As famous as this extinction event is, we know considerably less about how such disturbances affected ecosystems like tropical rainforests. That is where people like Dr. Mónica Carvalho come in. Together with her colleagues, Dr. Carvalho is using vast amounts of fossil evidence from both before and after the asteroid impact to paint a picture of how the tropical rainforests of what is now Colombia were affected by this global catastrophe. From the rise of angiosperms to a complete overhaul of insect/plant interactions, you will be amazed at what these fossils can tell us.

Ep. 300 - Reconstructing a Cretaceous Flora

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. 188 - On the Origin of Flowering Plants

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!
