  • 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

  • Podcast 275 - Big N Wormy

    17/12/2023 Duration: 01h39min

    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 are long with no legs. The first  paper looks at a small long animal that is actually pretty big for the  kind of animal that it is. It is very old and is found in a very cold  place. This is an important animal to find from a long time ago because  there are not a lot of these animals found at this time, and not a lot  of them in the cold. The fact that it is big could be a part of  something we see a lot where some animals get big to live in the cold.  The second paper looks at a long animals that moves through water and  some of them will eat parts of other animals while they are still  living. This paper is l

  • Podcast 274 - Cause and Effect and Cause

    03/12/2023 Duration: 01h27min

    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 Amanda smartly ignores things.   Up-Goer Five (Curt): The friends talk about two papers that look at the ways in which the things we know can be changed because of other problems that we do not always know are there to make things look like one thing but actually be another thing. The first paper looks at how not getting things to be saved over time could mean that you might not see the reason something happens until it looks like it is after that thing has happened. The paper uses a time in the past when it got very cold and looks at what could have made this happen. There are lots of talk about the growing of big

  • Podcast 273 - The Hunt for Red Plankton

    19/11/2023 Duration: 01h24min

    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 the events of the movie “The Hunt for Red October”. Yes, it is going to be “one of those” podcasts.   Up-Goer Five (Curt Edition): The friends talk about two papers that look at things that live in the water without having to move parts to stay in the water and maybe they are single cells and maybe they are groups of cells. The first paper looks very very old things that live in the water. These old things are so old and hard to figure out that people are not always sure what they are. These things are often thought to be all single cells. This paper shows that some of these things that are very old might be groups of

  • Podcast 272 - The Tardigrade Cast

    05/11/2023 Duration: 01h30min

    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-Goer Five (Curt Edition): The friends look at two papers that look at a group of animals that are very very very small and have been seen as cute by a lot of people even though you can not really see them without help. The first paper finds some of these very very small animals in bits that come out of things that grow big and make their own food. These bits get hard when they get covered in ground over a long time and things that get stuck in the stuff can be there. This paper looks at these old very very small animals and tries to see what they could be like. It also talks about how we might not have as good an i

  • Podcast 271 - Feel It In My Guts

    22/10/2023 Duration: 01h24min

    The gang discusses two papers that look at the gut contents and traces of ancient animals. The first paper reconstructs gut traces (or lack thereof) for Ediacarans and then the second paper looks at the detailed gut contents and 3d track of a lichid trilobite. Meanwhile, Amanda’s cat is changing careers, James is feeling “motivated”, and Curt has some house improvement recommendations.   Up-Goer Five (Curt Edition): The friends talk about the insides of different animals from a long long time ago. The first paper looks at animals from a long long time ago that do not look much like things we see today. There is a lot of talk about how these animal would eat and where the food would go when they did eat. This paper looks at the parts that remain and looks over the things that are left behind to see if they can find out what the insides of these things were like. What they find is that the things we think are more like things we see today all have insides where the food goes. The one really strange thing does

  • Podcast 270 - Rafting Away

    08/10/2023 Duration: 01h17min

      The gang discusses two papers that look at the provide clues to the modern biogeographic distribution of species, specifically bees and new world monkeys. Meanwhile, Amanda shares something, James finds out about where’s the beef in more ways than one, and Curt invents a band.   Up-Goer Five (Curt Edition): The friends talk about two papers that look at where animals live and how those animals got to those places. The first paper looks at group of small animals that fly and go to things that grow their own food and picks up parts of them when looking for food that helps these things that grow their own food make more of themselves. A long time ago, people had an idea that all of these small animals that fly came from one place and them moved to other places. No one had done a big paper using computers to see if this was true. This paper uses computers and finds that it does seem to be true. The second paper looks at small animals that move in trees and can not fly but are closer to people than lots of other

  • Podcast 269 - Baba Yaga's Whale Facts As Written By ChatGPT

    24/09/2023 Duration: 01h07min

    The gang discusses two papers that look at fossils of the early whale group Basilosauridae. Specially, these papers describe the largest whale recovered from this group, as well as the smallest whale from the group. Meanwhile, Amanda has a lovely home, James has some whale facts, and Curt has some art critiques.   Up-Goer Five (Curt Edition): The friends talk about two papers that look at one group of big animals that breathe air but move in the water that are no longer around today. These papers are looking at different animals within the same group. The cool thing about both of these papers is that they talk about the same thing, but from different ways of looking at it. This is because one of these papers is about the biggest animal that people have found in this group and the other paper is about the smallest animal found in this group. This is a big thing because this is a group that today has gotten really big and the reasons why these groups get big has been something people are really interested in.
