  • Podcast 293 - This Episode Doesn't Suck

    22/09/2024 Duration: 01h40min

    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 these animals look like angry animals today that move in water, and so this paper is looking to see if maybe they were both doing the same thing as what we see today. The paper doesn't come to a strong end, but it looks like maybe these things are doing things that maybe are not always the same as the things that live today that they look like. The second paper looks at two animals that need air but move in the water all the t

  • Podcast 292 - That's How You Get Ants

    08/09/2024 Duration: 01h07min

    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 is looking at some of these small animals that live on trees. These small animals can either live in a lot of trees or just one type of tree. The animals that live on just one type of tree also look a lot like each other. This paper looks at how and why this could be. The second paper looks at the color of small but angry animals that live along big bits of water. These animals can be lots of colors. They find that different co

  • Podcast 291 - DoInG vErY wElL tHaNk YoU

    25/08/2024 Duration: 01h46min

    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 first paper). But if you like us at our most rambling, then do I have a podcast for you!   Up-Goer Five (Curt Edition): Last edition? Oh no the up-goer five word thing has gone down. I can not make an up-goer for this. That makes sense for this because also this time the friends are tired and talking about lots of things that are not the papers, which are about how animals get big and where animals are. But since the nice pl

  • Podcast 290 - Want to Get Away

    11/08/2024 Duration: 01h29min

    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 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

  • Podcast 289 - The Brachiopod Paradox

    28/07/2024 Duration: 01h30min

    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 movies. This paper looks at how the teeth of some of these animals would grow over time. This group of big angry animals also does a lot of cool things with their teeth over a long time because they move from eating animals to eating things that do not move and make their own food from the sun. The big angry animals that they look at have lot of these animals from a lot of different ages so they can see how the teeth get changed

  • Podcast 288 - Some Meat on the Bone

    14/07/2024 Duration: 01h54min

    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 where animals may have been in the past. The first paper looks at animals with hair that live in the water and have moved into water that you and I can drink. This is a paper about one group of these animals and some bits of an old animal that were found in a place very far away from where these animals are today. This might mean that these animals moved into water than you and I could drink many times over the years and in

  • Podcast 287 - NAPC 2024

    30/06/2024 Duration: 04h26min

    The gang convenes in Ann Arbor, Michigan for the 2024 North American Paleontological Convention. We discuss the various talks we saw and highlights on the event. Most of Day 2 discussion starts at 1:03:01 Day 3 discussion starts at 2:19:00 Day 4 discussion starts at 3:22:56

  • Podcast 286 - Dinosaurs, Sabertooths, and Mojitos; Oh My!

    16/06/2024 Duration: 01h34min

    The gang discusses two papers that study ecological changes in the evolutionary history of some charismatic ancient animal groups. The first paper uses geographic data to infer the timing of the evolution of homeothermy in non-avian dinosaur groups, and the second paper looks at the mechanisms by which cats (and cat-like animals) developed saber teeth. Meanwhile, Curt makes some plans for Amanda, James muddles things over, and Amanda could use another.   Up-Goer Five (Curt Edition): The friends talk about two papers that look at how where animals live can change how they look and also maybe how they look can change where they can live. The first paper looks at old big angry animals and where they live to see if they can find when these animals were able to make themselves warm inside. We have other things that make us think that some of these big angry animals may have been able to get warm inside, but that this might have happened a few times in this group. By looking at where these animals were found in th

  • Podcast 285 - All Things Big and Small

    02/06/2024 Duration: 01h37min

    The gang discusses two papers that look into long term trends in body size over time. The first paper looks at body size trends in corals, and the second looks at body size and ecology of terror birds. Meanwhile, James loses a bit of himself, Amanda is bad at transitions, and Curt goes places no one wants to go.   Up-Goer Five (Curt Edition): The friends talk about two papers that look at how big things are and how that changes over time. The first paper looks at tiny animals that live together in a group and share their homes with even smaller living things that help give them food. It turns out that being small makes it good for the smaller things living with them. So this paper wants to see if these animals have been getting smaller over time. Turns out that it is not that easy, and that some of these earlier animals were bigger than today but probably did have even smaller living things with them helping them. But it seems like there is some bit of these animals getting smaller, so maybe these animals ha

  • Podcast 284 - How Complete Is Your Shark

    19/05/2024 Duration: 01h11min

    The gang discusses two papers that look at the shark fossil record. The first paper looks into the completeness of the record, and the second paper discusses the ecological implications of an exceptionally preserved specimen. Meanwhile, James has ideas of what is normal, Curt has a hard out, and Amanda shows her specific history interests.   Up-Goer Five (Curt Edition): The friends talk about two papers that look at animals with lots of soft parts that move through the water and have lots and lots of teeth. The first paper is looking at how well we know these animals in the past, since most of the time we may only know them by their teeth. They do a lot of things to see how much of the animals we have at any time. What they find is that, most of the time, we do not have many parts of these animals. However, there are some times in the past when we do see more parts that are not just teeth, so there might be times in the past that were better and making sure the soft parts were able to stick around and be foun

  • Podcast 283 - Stolen Podcast

    05/05/2024 Duration: 01h12min

    The gang discusses two papers about an interesting locality in South America and the various body fossils and ichnofossils found in this locality. This podcast originally started as a patreon request to podcast about fossil procyonids… but it ended up like this… ooops! Meanwhile, James has a vocal doppelganger, Amanda deals with being human, Curt deals with scams, and everyone talks way too much about visuals on an audio podcast.   Up-Goer Five: (Curt Edition) The friends talk about a place that has rocks from a long time ago that give us an idea of the types of animals that were around in the land areas under where the friends are today. The land where our friends are one used to not be touching the land that is under them like it is now. Once these two lands touched, then the animals from each land moved into the other lands. This place is from a time before these two lands had finished touching, so some animals moved over but others had not yet. The first paper looks at some parts of a type of animals tha

  • Podcast 282 - Early Fishies

    21/04/2024 Duration: 01h19min

    The gang discusses two papers that look at the morphology and ecology of early fishes. The first paper investigates a hypothesis for how the pectoral girdle could have evolved, and the second paper looks at the functional morphology of a Paleozoic jawless fish. Meanwhile, Amanda missed some context, James throws some shade, and Curt is annoyed by AI.   Up-Goer Five (Curt Edition): The friends talk about two papers that look at animals from a long time ago that live in water. The first paper looks at how part of the shoulder in people may have first started as a part of another part of the animal in these animals that lived in water a long long time ago. They find these parts of this animals from a long long time ago that they can use to see how the parts around the head grew. They use this to say that the shoulder parts may have started as a part of the thing these animals use to breath. The second paper looks at the mouth of a type of animal that lived in water a long long time ago that did not have a hard p

  • Podcast 281 - Climate and Extinction

    07/04/2024 Duration: 01h37min

    The gang discusses two papers that look at the correlation between climate change and extinction risk in the fossil record. The first paper uses climate modeling to simulate extinction risk during past periods of climate change, and the second paper uses new radiometric age dates to infer diachronous extinction between marine and terrestrial environments during the Permian mass extinction. Meanwhile, James orders food, Curt stirs the pot, and Amanda lives with her choices.   Up-Goer Five (Curt Edition): The friends look at two papers that look at times when a lot of things died. The first paper uses computers and numbers to see how things could die during times when things get real hot or real cold. They look at real times in the past when lots of things die during these cold and hot times, and then they use their computers and numbers to make those things happen in the world of a computer to see if they can find out what may or may not make that happen. They find that lots of things can cause animals to die

  • Podcast 280 - Just a Weird Little Guy

    24/03/2024 Duration: 01h06min

    The gang talks about two papers that look through existing museum collections to discover some fascinating new discoveries. Meanwhile, Curt may be haunted, James may be losing energy, and Amanda may not be real.   Up-Goer Five (Curt Edition): The friends look at two papers about new things that found when going through the stuff stored in a big building where you keep things so that people can look at them later. The first paper finds some really cool new small things that live in water that had been found before and put in a big building to keep things, but no one saw that these small things were not the same as the other small things. These small things are part of a group that lives in fast moving water that we usually do not get a lot of them in the ground. The second paper finds that a thing that was put in a big building a long time ago was actually a lie. This thing is not what everyone thinks it is and the paper looks into what it really is, which is that it is a painting on rock. The paper talks abo

  • Podcast 279 - Frogcast

    10/03/2024 Duration: 01h27min

    The gang discusses two papers that look at the fossil frog record. The first paper identifies fossil frogs from Antarctica, and the second paper looks at some exceptional soft-tissue preservation. Meanwhile, James has ideas for expanding the brand, Amanda asks for clarification on an important topic, and Curt makes some executive decisions.   Up-Goer Five (James Edition): The group looks at two papers that are interested in animals that are wrong and good at jumping and live in the water but some can walk on land and climb trees. The first paper is looking at one from the very cold land in the bottom of the round thing we live on, where we do not find any of them today because it is too cold. The animal is known by two small bits but we can tell what type of jumping thing it is and so we know it is part of a group that is found in two areas that do not touch today, but the place at the bottom of the round thing we live on is between them, so that makes sense! But it is very cold today, so that is strange, bu

  • Podcast 278 - The Wrong Shapes

    25/02/2024 Duration: 01h13min

    The gang discusses two papers that investigate evidence of symbiosis in the fossil record. The first paper looks at wormy organisms living inside Cambrian vetulicolians, and the second paper shows potential evidence of hydroids growing in mollusc shells. Meanwhile, Amanda is haunted, James’s computer is totally cooperating, and Curt may or may not have had to stitch this podcast together from other sources.   Up-Goer Five (Curt Edition): The friends look at two papers that look at animals that live inside of other animals. Sometimes these things live inside other things and both of the things do well because of it. Sometimes, these things live inside other things and they cause problems for the thing they live in. These two papers look at the ways we can see old bits of things that used to live in other things and how we can try and figure out why they might have lived inside other things. The first paper looks long animals living inside a weird animal from a long long time ago. These long animals are all in

  • Podcast 277 - Bird Tracks For Fun and Profit

    11/02/2024 Duration: 01h28min

    The gang discusses two papers that look at Mesozoic tracks that may or may not have been made by an avian archosaur. Meanwhile, Curt becomes activated, Amanda has to deal with harsh truths, James gets creative with taxon names, and everyone get distracted very quickly. (Editor’s Note: If you want to just “get to the science” skip to 11 minutes in. We hadn’t talked in 2 months and it shows. I just didn’t have the heart to cut all of it)   Up-Goer Five (Curt Edition): The friends look at two papers that look at foot falls in the ground from a very very long time ago which may or may not be made by animals that can fly through the sky, or may have been made by big angry animals. The problem is that big angry animals and the animals that can fly are very close to each other, and their foot falls can look a lot like each other. The first paper looks at some very old foot falls and some of these foot falls do look like they were made by animals that can fly, but that would be very very strange because it would nee
