Podcast 339 - Back on Our Bullshit
Palaeo After Dark
The gang discusses two papers that use fossils to understand ecological interactions in the past. The first paper reports predation patterns on fossil blastoids, and the second paper finds brooding in the soft tissue of fossil bivalves. And then… the gang gets very much back on their bullshit… Meanwhile, James simplifies his life, Curt discusses new business ventures, and Amanda is seen. Up-Goer Five (Curt Edition): The friends look at two papers that look at how animals from a long time ago lived their lives. The first paper looks at a group of animals made of small hard parts...

Podcast 338 - Trilobite and Terror Bird
Palaeo After Dark
The gang discusses two papers that describe fossils which provide glimpses into the evolution and ecology of animals that were “late editions” to their clade. In other words, this podcast is focusing on fossils whose ages place them were close to the extinction of their respective groups. The first paper identifies ecological preferences in late Paleozoic trilobites, and the second paper describes a terror bird from South America that provides further evidence for a younger extinction of the group than traditionally understood. Meanwhile, Curt proposes a sitcom, Amanda has great timing,...

Podcast 337 - Smol Beeg Animals
Palaeo After Dark
The gang discusses two papers that look at early tetrapods. The first paper investigates the transition to terrestrial environments in early tetrapods, and the second paper looks at some very small Dimetrodon. Meanwhile, Amanda has a disproportionate cat, James talks smack about a dead synapsid, and Curt gives gardening tips. Up-Goer Five (Amanda Edition): This week our friends look at two papers on animals with hard bits in their back and four legs. The first paper asks when did animals with hard bits in their backs and four legs first start doing a big change as they grew up. Today...

Podcast 336 - Who Needs a Jaw?
Palaeo After Dark
The gang discusses two papers about jawless fishes. The first paper looks at some soft tissue preservation of early vertebrates which include preserving evidence of an ancient heart, while the second paper investigates how the fossil record of hagfish can inform the order in which characteristics evolved within the group. Meanwhile, James “solves” his problems with machines, Amanda keeps making new friends whether they like it or not, Curt claims no responsibility, and everyone loves these kawaii line drawings. Up-Goer Five (James Edition): This week the group look at two papers...

Podcast 335 - I Like Turtles
Palaeo After Dark
The gang discusses two papers that use fossil material to assess the origin of animal groups. The first paper describes a new Early Devonian fish and its implications for the evolution of jaws, and the second paper reassesses the fossil material of turtles (and possible not turtles) to determine where turtles fit on the evolutionary tree of sauropsids. Meanwhile, James invents new flavors, Curt breaks things down, and Amanda sets boundaries. Up-Goer Five (Amanda Edition): Today our friends look at two papers that talk about things showing up for the first time. The first thing to show...

Podcast 334 - Stuck on You
Palaeo After Dark
The gang discusses two papers about encrusting organisms. The first paper looks at evolutionary patterns of bryozoans to infer environmental triggers for shifts in the ways bryozoans calcify. The second paper uses the distribution of encrusting organisms on spirifd brachiopods to infer the ecology of both the encrusters and the brachiopod they grew on top of. Meanwhile, James discovers new foods, Amanda constructs a worm, and Curt gets confused and makes it everyone’s problem. Up-Goer Five (Curt Edition): The friends talk about two papers that look at animals that do not move around...

Podcast 333 - Think Big
Palaeo After Dark
The gang discusses two papers about fossil cephalopods. The first paper uses new methods to reassess the taxonomy of what was previously considered to be the oldest octopod, and the second paper uses preserved beaks to reconstruct large body sizes of Mesozoic octopods. Meanwhile, Amanda keeps it within Michigan, James brings up THE cephalopod talk, and Curt ascends. Up-Goer Five (Curt Edition): Our friends talk about two papers that look at animals with many arms and a sharp mouth. The first paper looks at some parts of a very old animal with many arms. People thought that it might be...

Podcast 332 - Bird Peepin'
Palaeo After Dark
The gang discusses two papers that investigate phenotypic plasticity. The first paper reviews the pathways by which phenotype can be plastic, and the second paper looks at plasticity of breeding times in urban vs rural bird populations. Meanwhile, James manages a basement, Amanda names the papers, and Curt makes allegations. Up-Goer Five (James Edition): Today the group look at two papers that are interested in how animals change because of the type of place they live. The first paper is looking at different ways that animals can be changed, either by being changed as they grow or by...

Podcast 331 - Reef It Up
Palaeo After Dark
The gang discusses two papers that investigate ancient bioherms. The first paper looks at the formation of early Phanerozoic reefs, and the second paper investigates patterns of reef building and collapse in the late Devonian. Meanwhile, James is being advertised to, Amanda plans unique roadtrips, and Curt solicits legal advice. Up-Goer Five (Amanda Edition): Today our friends talk about animals that have green friends that make hard bits. These animals that make hard parts are really important today because they make good places for other animals to live. But we don't know all about...

Podcast 330 - Dinosaur Body Pillow
Palaeo After Dark
The gang discusses two papers about the functional morphology of ancient groups of animals. The first paper is a review of how the life position of rangeomorph ediacaran taxa have been reconstructed, and the second paper conducts an actualistic experiment of Oviraptor nesting strategies. Meanwhile, Curt gets activated, James doesn’t die, and Amanda relishes in details. Up-Goer Five (James Edition): The group look at two papers that focus of understanding how things are long dead lived. The first paper talks about strange things that might have either lived standing up or lying down...
info_outlineThe gang discusses two papers that use fragmentary fossils of animals to investigate the origins of major groups. The first paper describes an Early Ordovician eurypterid, and the second paper looks at mosaic evolutionary patterns in an early squamate. Meanwhile, James has bird opinions, Curt delights in not knowing, and Amanda will definitely be on time.
Up-Goer Five (Curt Edition):
The friends look at two papers that are using broken bits of things to learn a lot about animals from a long time ago. Both of these papers are looking at old animals that may give us new looks at how big groups of animals changed over time. These animals may be some of the first animals in these groups, or at least let us know what kinds of things those early animals could have been doing. The first paper looks at a group of animals that lived in the big blue wet thing a long time ago and are part of a group that today has animals that make homes that they use to catch food. The new parts this paper finds shows that this group may have come around a lot earlier than we thought. The second paper looks at parts from an animal that is in a group that is cold and has hard skin, some with legs and some without legs. These parts show that the early animals in this group had a lot of changes going on in their hard parts, maybe they changed more early on then they do today.
