Palaeo After Dark

The gang discusses two papers that look at... well... let's be honest here... we really didn't have much of a hook. You see, James was slammed with bureaucratic work, Curt was knee deep in grading hell, and Amanda was traveling for the holidays. So we made... this; a podcast about a worm and a lamprey.    We're sorry.   Up-Goer Five (Curt Edition): The friends look at two papers about animals that...

The gang discusses two papers about taphonomy and its influence on our understanding of the fossil record. The first paper looks at how taphonomic processes can blur our understanding of cause and effect, while the second paper looks at the impacts of collector and size biases on our understanding of the ecology of an ancient plant. Meanwhile, James deals with spirits, Curt gets philosophical, and...

The gang discusses two papers that look at plankton through time. The first paper looks at some Cambrian acritarch fossils and shows that they are likely colonial algae, and the second paper looks at how shifting temperature affected plankton distribution across the Cenozoic. Meanwhile, everyone stays completely on task with the stated goals of this podcast: a detailed (and wrong) discussion on th...

The gang discusses two papers that deal with the evolution of tardigrades. The first paper looks at some fossil tardigrades in amber, and the second paper looks to the Cambrian to determine the ancestors of modern tardigrades. Meanwhile, Amanda confuses some details about medication, James has some money making crab solutions, and Curt is somehow the one person trying to keep people on track.   Up...

The first p...

The gang discusses two papers that use Blender 3d modeling techniques (and other functional morphology techniques) to study arthropod morphology. The first paper looks at trilobite enrollment and the second paper looks at the anomalocaris great frontal appendages. Meanwhile, James likes horses, Amanda has some name ideas, and Curt fails to segue.   Up-Goer Five (Amanda Edition): Today our friends...

The gang discusses two papers that looks at mammal jaws and teeth. The first paper uses many different analyses to study how the mammal jaw evolved, and the second paper looks at a unique set of teeth in a fossil whale group. Meanwhile, Curt gets ideas from Mortal Kombat, James has discusses farming practices, and Amanda finds any excuse to be fabulous.   Up-Goer Five (Curt Edition): The friends t...

The gang discusses two papers that look at examples of unusually large animals in the fossil record; one large lacewing larvae and one very large skink. Meanwhile, James is having a great day, Amanda starts a chant, and Curt learns the true meaning of "cool fossil bro".   Up-Goer Five (Curt Edition): The friends look at two papers about things that are big for what they are. The first paper is a t...

The gang discusses two papers that look at the ecomorphology of Mesozoic swimming reptiles. The first paper investigates swimming strategies in various marine swimming reptile groups, and the second paper looks at changes in the skull of mosasaurs compared to stem whales. Meanwhile, James has a meal, Amanda "makes" animals, and Curt needs more insight.   Up-Goer Five (Curt Edition): The friends lo...

The gang discusses two papers that look at the impact of humans on bird populations. The first paper looks at the history of a condor nesting site in the Andes, and the second paper looks at the impact of artificial light on the circadian rhythms of urban bird populations. Meanwhile, James is highly engaged, Curt tries to sell some property, Amanda finds something slightly more horrifying, and eve...

The gang discusses two papers that study the paleoecology of the Ediacaran fauna. The first paper looks at environmental information that can be gleaned from the microbial mats these organisms lived on, and the second paper studies how different Ediacaran fossils are distributed on this microbial mat. Meanwhile, James is having a week, Curt is unsure about chips, and Amanda is comfortable being ve...

The gang discusses two papers about inferring life habit and ecology from extinct animals. The first paper summarizes the data for ichthyosaur birth to see if they really do preferentially come out tail first, and the second paper investigates a fossil that could complicate the narrative for the origins of a European sabretooth cat group. Meanwhile, James has opinions about browsers, Amanda is cam...

The gang discusses two functional morphology papers. The first paper looks at eye placement and skull morphology in Thylacosmilus and the second paper looks at the ungals of maniraptoran theropods. Meanwhile, James has milk filled "vegan" food, Amanda is replaced by alternate universe goatee Amanda, and Curt looks to rebrand.   U p - G o e r F i v e ( C u r t E d i t i o n ) : The friends talk abo...

The gang discusses two papers that look at patterns of niche conservatism or niche evolution in the fossil record. The first paper looks at the pollen records of trees in Portugal to test if changing climate can explain modern tree distributions, and the second paper looks at the impact of Late Devonian extinction pulses/invasions on brachiopod communities. Meanwhile, Curt summarizes the podcast,...

The gang discusses two papers that look at some Cambrian problematic fossils and find new clues that allow us to determine what groups they might belong to. One paper finds new evidence that some of these tube fossils in the Cambrian may be cnidarians and the other paper identifies potential gastropod radula in Cambrian rocks with adaptations for grazing. Meanwhile, James is not at all tired, Aman...

The gang discusses two papers that use morphometric studies to investigate patterns of ecomorphy in the fossil record. Specifically, they look at two papers that investigate how morphology in sloths and pterosaurs changes over time, and how well these changes map onto changes in body size and ecological shifts. Meanwhile, Amanda could be dean, Curt has opinions on figures, and James provides butch...

Meanwhile, Amanda is 10 minutes away from being taken to Oz, Curt invents a new adaptation, James figures out perpetual energy, and everyone i...

The gang celebrates their 10 year anniversary by talking about two papers on the same topic that are 10 years apart. Both papers take a critical look at how we define the "big five" mass extinctions and what this term means. Meanwhile, everyone waxes philosophical for the last 20 minutes, discussing how things have changed in our lives since we started this weird show. Thanks for listening!   Up-G...
