Podcast 181 - Before the Pain; The Root of the Problem
16/02/2020 Duration: 01h21minThe gang discusses two papers about unique fossil preservation. One paper looks at how fossil root systems can inform our understanding of early Devonian forests, and the other paper shows how slime molds can be preserved in the fossil record. Meanwhile, Amanda is excited for questionable reasons, James prepares for the pain, and Curt learns his role in the friendship. Up-Goer Five (Amanda Edition): Today our friends talk about weird cool things that have only one piece but can get very big, and the tall green things with many pieces above and under ground, that is trees. Because trees is a word we can use. We focus on the pieces under ground. The weird cool things that have only one piece are found in old tree blood. The part of the weird cool things that have only one piece look kind of like things that are good to eat but might also kill you that grow on the ground. They are where the weird cool things that have only one piece make more of themselves. They are very very old but look just like pieces arou

Podcast 180 - Worms and Snails
02/02/2020 Duration: 01h14minThe gang returns back from their winter break to discuss two papers that look at the important information we can glean from soft-bodied organisms in the fossil record. First, we take a look at a paper that shows some incredible preservation of Cretaceous snails in amber and how we can use that exceptionally preserved material to infer important information about the evolutionary history of these groups. Second, we talk about a cool example where hypotheses pulled from trace fossils can inform the distribution of modern worm species. Meanwhile, Amanda was not content with being driven mad by just TWO cats, James somehow manages to complain about being good at things, Curt spills the secrets on his friends, the internet TOTALLY doesn’t mess up our recording, SpaceX should probably paint their satellites, and we completely stay on topic this entire time….. believe me….. Up-Goer Five (Curt Edition) The friends talk about two papers about things that have soft bodies. First, the friends talk about a paper where

Podcast 179 - Pollinators and Begging Grubs; Studies of Insect Behavior
19/01/2020 Duration: 01h03minThe gang discusses two papers on insect behavior, one fossil study and one modern study. The fossil study illustrates a cool example of how amber can help us to understand the evolution of pollination throughout Earth history. The modern paper investigates how bury beetles care for and communicate with their young. Meanwhile, James’s computer lives in the past, Amanda has to deal with cat-nap related choices, Curt has his honor besmirched, and everyone is a little overwhelmed by how little people care about invertebrates. Up-Goer Five (Amanda Edition): Today our friends talk about small things with six legs. Some of these small things with six legs go to green things with pretty colored bits and take their tiny baby parts, and take them to other green things with pretty colored bits. It might be that a long time ago, when green things with pretty colored bits were new, that small things with six legs and sort of hard parts over their flying parts were the ones that took the tiny baby parts of green things

Podcast 178b - "Paradise Falling" Part 2
05/01/2020 Duration: 01h51minThe gang celebrates the end of the year by taking another break to play Fiasco, a crime/noir storytelling game by Bully Pit Games. Here is the conclusion of our two part episode. Business in the Blue Label Diner was picking up, and Bill Larsen was all action; balancing plates, refilling coffee, and distributing orders with a speed that belied his aging body. All the while, he never ceased telling his narrative of the town’s recent history to the woman from out of town who was still sitting in that same seat at the counter. It was as though the act of relaying this history was somehow feeding him an otherworldly energy. “So I know that a lot people from outside uh’ our town might not really get it… But ya see Mr. Cromwell brought somethin’ important to this town. The Hub brought more than just jobs, it brought a purpose. It made this town important, put us on the map. And sure, we don’t really go outside at night all that much anymore…” he looked out his window at the thick smoke which now pushed heavily aga

Podcast 178a - "Paradise Falling" Part 1
22/12/2019 Duration: 01h53minThe gang celebrates the end of the year by taking another break to play Fiasco, a crime/noir storytelling game by Bully Pit Games. This campaign will be broken into two parts. The afternoon sun cast long, hazy blades of light across the linoleum floor of the Blue Label Diner in downtown Paradise Falls. Bill Larsen took a moment to stretch his aching back before hunching again to buff the counter with his cleaning rag. With weary eyes, he turned his attention back to the out-of-towner who was furtively sipping her coffee. She pulled out a notebook and pen from her jacket pocket and set them expectantly on the counter, waiting for Bill to speak. “Do ya want some apple pie? Best in town.” No other restaurant in Paradise Falls sold apple pie, and Bill knew that. The woman shook her head, “Mr Larsen, I’m just here to learn the facts about what happened in your town. So please…. from the beginning…” “How did it all happen? Well that’s a long story.” He paused and gave a winking smirk “Ya sure ya don’t need someth

Podcast 177 - Grow a Spine
08/12/2019 Duration: 01h34minThe gang discusses two papers that look at how the morphology of tetrapods (animals with four limbs and a backbone) has changed over time. One paper looks at how dinosaur jaws are related to diet preferences, and the other paper looks at how spines have changed as tetrapods diversified through time. Meanwhile, James talks Star Trek, Curt gives some consumer advice, and Amanda would rather not talk about cowboys. Up-Goer Five (James Edition): This week the group look at two papers that are looking at different ways that animals get more different. The first paper is looking at the mouths of big angry animals with no hair. The big angry animals with no hair that eat other animals and get big have the least different mouths from each other, but those that are small and eat other animals have very different mouths from one another, and those that eat living things that make their own food or both other animals and living things that make their own food have the most different mouths from one another. We see the

Podcast 176 - Much Ado About Teeth
24/11/2019 Duration: 01h21minThe gang discusses two papers that look at changes in teeth through time. The first paper looks at the earliest example of heterodont teeth in tetrapods, and the second paper looks at how different mammal groups build sabre tooth morphologies. Meanwhile, James has unique ideas for building worker morale, Amanda accidentally makes a pie faux pas, and Curt is friend to gelfling. Up-Goer Five (Amanda Edition): Today our friends talk about teeth. Wow, teeth is one of the ten hundred most used words. Cool. So some things have teeth that are all the same kind. Most of the very early things with four feet that go on long have teeth of all the same kind. But there is an early thing with four feet that goes on land that we have known about for a long time that was never really looked at too close and now we see that it has teeth that are big and round and teeth that are small and pointed. It was probably eating things that were very hard and needed to be broken up before it could eat them. What is cool is that there

Podcast 175 - Big Data Studies
10/11/2019 Duration: 01h21minThe gang discusses two papers that use large data sets to look at big picture patterns in evolution and ecology. Specifically, they look at one paper that explores brachiopod shell thickness in relationship to environmental preferences during the Late Ordovician mass extinction, and another paper that looks at the evolution of using the tail as a weapon in vertebrates. Meanwhile, James is eternally “young”, Curt invents unique ecological roles for Stegosaurus, and Amanda enables the worst type of ASMR (for those who cannot handle food sounds in microphones, skip 47:57-48:54). Up-Goer Five (Curt Edition): Our friends talk about two papers that bring together a lot of facts about things to say something about how living things have changed over time. The first one looks at hard rock like things that take food out of the water. This paper looks at how thick the hard parts of these things were and it focuses on a time when these things went through a real bad time and a lot of them died. While the paper finds a

Podcast 174 - Feeling Drained; Parasites in the Fossil Record
27/10/2019 Duration: 01h06minThe gang talks about two papers that look at potential examples of parasitism in the fossil record. One paper finds possible parasites attaching to ancient ostracods, and another paper details potential parasitic isopods on electric ray fossils. Meanwhile, James practices his spidey sense, Curt is suspicious that things are going too well, and Amanda’s internet has amazing timing. Up-Goer Five (Amanda and James Edition): Today our friends talk about animals that eat other animals without killing them. First our friends talk about a paper that talks about an animal that has big teeth but no hard inside parts even though it is in a group that has hard inside parts and lives in the water. This animal has a number of smaller animals that have sort of hard outer parts, that may have been living on its skin by sticking its head inside its skin and living there. It is very hard to tell if this thing had its head in the animal with big teeth and no inside hard parts when it lived, or if it was just maybe eating th

Podcast 173 - Early Plants
13/10/2019 Duration: 01h20minThe gang discusses two papers that look into early plant evolution and ecology. The first paper looks at some evidence from fossil spores to determine where the earliest vascular plants on land may have evolved. The second paper looks at a unique Devonian forest ecology from China. Meanwhile, James accidentally hoists himself, Amanda is more heard than she thinks, Curt fails as acting like everything’s ok, and everyone has a good old time working around Amanda’s computer deciding to die. Up-Goer Five (Curt Edition): Our friends talk about old things that can make their own food from the sun. First, they talk about some of the oldest things that make their food from the sun which also have ways of moving water from the bottom of the thing to the top. Before this paper, it was thought that things which make their food and live on the land probably first started in the big piece of land that used to be made up of most of the other land pieces put together. With this paper, they found parts of these things whic

Podcast 172 - GSA 2019
29/09/2019 Duration: 05h17minJames, Brendan, Aly, Carlie, Anna, and Curt gather together at the 2019 Geological Society of America Meeting in Phoenix and discuss the various paleontology talks they saw at the event. Day 1 (Anna, James, Curt, Brendan): 0:00 - 1:05 Day 2 (James, Aly, Carlie, Brendan, Curt): 1:05 - 2:37 Day 3 (James, Anna, Curt): 2:37 - 3:54 Day 4 (James, Carlie, Brendan): 3:54 - 5:17

Podcast 171 - Birds Get Swole in New Zealand
15/09/2019 Duration: 01h39minThe gang discusses some very interesting papers about bird fossils in New Zealand. These papers describe how many different types of birds ended up on New Zealand throughout the Cenozoic, and each time they experienced significant increases in their size. Sadly, since this was a very straightforward topic, no one could quite manage to focus on anything. So meanwhile, Curt remembers childhood animations that no one cares about, James makes it “fun” for himself and no one else, Amanda drinks the unholy combination of bourbon and rye (brye?), and everything just kind of gets way too 2019 near the end (EDITOR’S NOTE: Apologies for the inconsistent audio on this episode. The wrong inputs were used for some of the audio due to some last minute changes, but this should not happen in the future). Up-Goer Five (Amanda Edition): Today our friends talk about things with no teeth that can fly that can't actually fly and live on land that has water all around it. One of these things with no teeth that can fly but can't

Podcast 170 - The Impact of Taphonomy; On Conodonts and Dinosaur Nesting Sites
01/09/2019 Duration: 01h16minThe gang discusses two very different papers that are sort of united together based upon the importance of taphonomy. First, they look at a paper about how the ways in which conodont elements are preserved can affect our understanding of their evolution. Second, they talk about the recent finding of exceptionally preserved therizinosaur dinosaur nesting sites. Meanwhile, Amanda finds herself dealing with a failing webcam, Curt enjoys burying the lede, and James is never wrong unless he wants to be. Up-Goer Five (Curt Edition): Our friends talk about how the ways that things wear down can really change how we understand our past. First, they look at these things that are like teeth but are not and are part of this very old group of animals that are aunt or uncle to a lot of animals that have hard parts in their backs which live today. Some of these old animals that have not teeth have changes through time in their not teeth. The bottom of these not teeth appears to disappear in the animals we find which are

Podcast 169 - Learning about Agnostids
18/08/2019 Duration: 01h26minThe gang takes some time to discuss two papers about agnostids, a strange group of trilobite-like arthropods whose evolutionary history has been the subject of considerable debate. First, we discuss a short paper summarizing the history of the agnostid debate, and then we discuss a brand new paper using new material and Bayesian phylogenetics to offer a fresh new hypothesis. Also, James channels frustration into fun, Amanda nearly has her house destroyed by cats, and Curt asks the Star Wars questions no one wanted answered. Up-Goer Five (Amanda Edition): Today our friends talk about small animals that have no eyes that might be sisters of animals that live in the water that have three parts and big eyes, many legs, and can make themselves into a ball. The first paper talks about the small animals with no eyes and how hard it is to make one of these animals for people to look at. They talk about the past of the animal and where it lived, and who it might be close sisters to. They say that a very cool area wh

Podcast 168 - Alligator Teeth and Too Small Cats
04/08/2019 Duration: 01h01minThe gang discusses two papers that look at the diets of past and present crocodylomorphs using patterns in teeth shape and enamel. It turns out, past relatives of crocodiles were likely a lot more experimental in the types of feeding strategies they implemented than we might expect. Meanwhile, Curt comes up with a great name for a Lamsdell lab bowling league, Amanda loves possums, and James has some very strong opinions about the “Cats” trailer. Up-Goer Five (Curt Edition): The friends talk about two papers that look at the teeth of these big angry animals that hide and eat a lot of animals. It turns out that lots of these big angry animals are sons and daughters of older big angry animals which may have ate other things besides animals. These two papers look at the teeth of the living big angry animals and the older big angry animals to see what we can learn about what they may have ate. The first paper looks at the hardest bits that cover the teeth. In living big angry animals, they find that the teeth fu

Podcast 167 - Jet Lagged Pterosaur Eggs
21/07/2019 Duration: 01h21min[TRIGGER WARNER: Some dead baby jokes because we were in a very weird mental place, and also way too much rambling conversations about Star Wars] The gang celebrates their cross continental trip to the 2019 North American Paleontology Convention by immediately getting on microphone the next day to talk about fossil Pterosaur eggs and what they can tell us about Pterosaur reproductive strategies. As expected, this may not have gone well. Witness the horror as barely conscious minds try and keep on topic for more than about 5 minutes! Apologies to the authors of these quite nice papers. [Editor’s note: The scientific discussion on this podcast “starts” around the 10 minute mark] Up-Goer Five (Amanda Edition): Today our friends talk about animals with skin arms. We are really talking about the baby animals with skin arms when they live in a small house with a hard outer part. One paper talks about the house of a baby animal with skin arms that is very round and good. You can see all the small bits of this hous

Podcast 166 - NAPC 2019
07/07/2019 Duration: 05h10minWe all just got back from the 2019 North American Paleontological Conference at UC Riverside with an extra long (over 5 hours) episode. Join James, Carlie, Curt, and Brendan as they discuss the talks they saw each day of the conference. Time stamps for each day: Day 2 talks ~ 54 min.; Day 4 talks ~2 hr, 36 min; Day 5 talks ~3 hr, 49 min.

Podcast 165 - Sharks for St. Crispin's Day
23/06/2019 Duration: 01h12minThe gang have a “Shark Week” and discuss two papers about the ecology of modern tiger sharks. The first paper talks about a unique feeding strategy for some tiger sharks in which they can consume a fairly large amount of song birds. The second paper discusses how tiger shark populations are distributed around the islands of Hawaii, a place known for fairly high concentrations of tiger sharks. Meanwhile, James informs us of an important holiday, Curt imagines the ultimate battle of goose and shark, and Amanda decides to take charge of the podcast. Up-Goer Five (Curt Edition): Our friends talk about two papers that look at how these big animals with teeth that move through the water live. The first paper looks at what these big animals in the water are eating. People have been catching these big animals in the water and seeing what is inside of them. During some times in the year, usually the fall, these big animals in the water somehow eat a whole hell of a lot of these very small animals that talk a lot and

Podcast 164 - Rails and Snails
09/06/2019 Duration: 01h08minThe gang talks about two papers that are interested in iterative evolution, the repeated evolution of the same or similar morphological characteristics within or among species. Specifically, they are focused on iterative evolution in species on islands. The first paper they discuss looks at how being flightless might have evolved multiple times on the same island within the same species of rails. The second paper looks at repeated changes in developmental timing associated with climatic changes on an island. Also, James is an expert, Curt comes up with the best new Blue Sky series for the USA network “Rails and Snails”, and Amanda changes the podcast’s format. Up-Goer Five (Curt Edition): Our friends talks about two times that weird things happen when animals get on an piece of land that is surrounded on all sides by water. The first paper looks at small light flying things. When these flying things get onto a piece of land surrounded by water, they seem to stop flying. However, they find these remains of t

Podcast 163 - Triassic Fish Questions
26/05/2019 Duration: 01h27minThe gang discusses two papers that look at the extinction and survivorship patterns of clades across the Triassic mass extinction event. Specifically, they look at changes in morphospace in ray-finned fishes as well as phylogenetic patterns of extinction in early archosaurs. Interestingly enough, both studies suggest very low ecological selection (at least in the characteristics we can study in the fossil record), but the archosaur study shows clear phylogenetic clustering of extinction. Meanwhile, James works on his social media engagement, Amanda perfects the concept of a joke, and Curt discovers this podcast’s theme far too late. Up-Goer Five (Curt Edition): The friends talk about two papers which look at a time that was really bad when nearly anything died. But this time is slightly different from the other, more well known ones. Its not the biggest, and its not the one everyone thinks of. Instead, this bad time when everything dies happens just a little after the worst of the bad times where everything
