Podcast 297 - Amanda Falk is Still a Threat
Palaeo After Dark
The gang discusses two papers that look at patterns of mosaic evolution, one paper looking at cat evolution and the other paper looking at bird ecomorphy. Which means the gang talks about Amanda’s two favorite taxonomic groups. Meanwhile, Curt enjoys some realistic bird calls, Amanda remains a threat, and James provides relevant “facts”. Up-Goer Five (Curt Edition): The friends take a look at how animals change over time and how the parts of the animals might change in different ways at different times. The first paper looks at cats and things that are like cats, and they look at...

Podcast 296 - An Arm and a Head
Palaeo After Dark
The gang discusses two papers that detail interesting findings about the soft tissues of extinct arthropods. The first paper does a detailed study of the limbs attached to the trilobite head. The second paper describes the newly discovered head of the ancient myriapod Arthropluera, and discusses the larger implications this fossil has for the evolution of millipedes. Meanwhile, Curt explores new advertising ventures, Amanda unpacks automotive anxiety, and James has no ethical complications to report concerning this podcast. Up-Goer Five (Curt Edition): The friends look at two papers...

Podcast 295 - EeMoo or EeMyu
Palaeo After Dark
The gang discusses two papers that look at examples of soft tissue preservation during the Cambrian. The first paper is a deep dive into the sedimentology and paleoenvironment of the Emu Bay Shale. The second paper makes some interesting claims about soft tissue preservation in a marginal marine environment. Meanwhile, James needs some shortcuts, Curt is locked up, and Amanda should be blamed for everything that happened here. Up-Goer Five (Curt Edition): The friends look at two papers that look at animals from a long long time ago that lived in the water and were soft but were able to...

Podcast 294 - The Motherload
Palaeo After Dark
The gang discusses two papers that look at two Lagerstätten (fossil localities of exceptional preservation). The first Lagerstätte is a unique complex early Triassic community found near the equator, and the second Lagerstätte is a collection of exceptional trace fossils from the Pennsylvanian. Meanwhile, James is convinced in the existence of a town that doesn’t exist, Amanda takes an unexpected break, and Curt once again needs to be redacted. Up-Goer Fiver: (Curt Edition) The friends talk about two papers that look at times when there was a lot of things in the rocks that we do...

Podcast 293 - This Episode Doesn't Suck
Palaeo After Dark
The gang looks at two papers that compare similar structures in unrelated animals to see if there might be evidence of convergence. The first paper compares Spinosaurus to phytosaurs and the second paper compares the hyoid bone of ichthyosaurs and toothed whales. Meanwhile, Curt will try it, James waits for something that never happens, and Amanda has a surprise. Up-Goer Five (Curt Edition): The friends talk about two papers that look to see if animals that are not close are the same in ways because of what they do. The first paper looks at too old and dead big angry animals. Both of...

Podcast 292 - That's How You Get Ants
Palaeo After Dark
The gang discusses two papers that look at convergence (maybe?) in modern arthropods. The first paper looks at plant/ant symbiosis in a genus of ants, and the second paper looks at color patterns in crayfish. Meanwhile, James sees through time, Amanda disappears, and Curt plays on everyone’s worst fears. Up-Goer Five (Curt Edition): The up-goer thing is back and able to be used so we are now happy! The friends look at two papers that look at how animals can look a lot like each other. In this case the animals are really small and made of small hard parts put together. The first paper...

Podcast 291 - DoInG vErY wElL tHaNk YoU
Palaeo After Dark
The gang discusses two papers that... ok look. I'm going to level with you. No one in this podcast slept more than a few hours before we started recording. One of us was stuck on a plane and didn't get back home until 5 am the day of recording. Everyone was tired and stressed and so we all use this time to vent and drink. Sure, there are papers we talk about: growth rates of Triassic archosaurs and geographic gaps in our early tetrapod record. However, if what you want is focused discussion of the papers, this is not the podcast for you (it takes us 8 and a half minutes to get to the...

Podcast 290 - Want to Get Away
Palaeo After Dark
The gang discusses two papers that look at modern bird migration patterns. The first paper looks at breading and migration patterns of the American woodcock, and the second paper looks at how migration could function as a motor of island speciation. Meanwhile, James is cursed with consciousness, Amanda is on point, and Curt's jokes are consistently ignored. Up-Goer Five (Curt Edition): The friends talk about two papers that look at how animals that move in the sky may move a long way to get to a new home every year. The first paper looks at one fun animal that moves up and down along...

Podcast 289 - The Brachiopod Paradox
Palaeo After Dark
The gang discusses two papers that look at functional morphology in extinct groups. The first paper looks at tooth replacement patterns in an Ornithischian dinosaur, and the second paper studies the shell articulation of Rafinesquina to unravel a long-standing mystery. Meanwhile, James has questions about taste, Amanda forgets protocol, and Curt indulges in his fixations. Up-Goer Five (Curt Edition): The friends talk about two papers that look at how animals did things a long time ago. The first paper looks at a group of big angry animals that are liked a lot and make their way into...

Podcast 288 - Some Meat on the Bone
Palaeo After Dark
The gang discusses two papers that use new fossils to add insight into the geographic origins of groups. The first paper looks at some fossil freshwater dolphins and the second paper looks at fossil jumping spiders. The gang also uses these two papers to talk about a lot of other things because, despite being short papers, there is a lot of related things to talk about. Meanwhile, James is pretty sure he read the papers, Curt has very uninformed opinions, and Amanda gives everyone a panic attack. Up-Goer Five (Curt Edition): The friends talk about two papers that use old animals to see...

Up-Goer Five (Curt Edition):
The friends talk about two papers that look at how animals that move in the sky may move a long way to get to a new home every year. The first paper looks at one fun animal that moves up and down along the land where the friends live as everything gets warmer or colder. People have now been following these animals using big things in space that can show where something is, and this is what the paper uses to see how these animals move and how long they stay in one place. They also have people go to these places to make sure the animals are really there and that they are doing the things they think they are doing. This paper finds that these animals also make babies in many of the places that they go. Many animals that move a lot will only have babies once when they get to their new home, but these animals keep making babies in different places as they move. This paper shows that they are doing it and gives some ideas as to why they might be doing this.
The second papers looks to see if some of the animals that are stuck on small land with water on all sides. This paper wants to know if a lot of those animals come from animals moving a long way to a new home and getting lost and ending up on this small land. They run a lot of studies to see how many of these animals may have ended up on these small lands this way. And then, they look at other things that these animals have to see if there are big reasons why some animals get stuck. What they find is that a lot of the animals are there because they go stuck. They also find that animals that live in a lot of places and that move with a lot of other animals were the ones that were going to get stuck. This could be because having more of you in more places makes it so you can have at least one group of animals get stuck.
