Palaeo After Dark

The gang discusses two papers that investigate the feeding strategies of ancient animals, including a fossil stingray and an ancient bird. Meanwhile, James is recovering, Curt refuses to do his job, and Amanda is in podcast heaven but teetering over podcast hell.   Up-Goer Five (Curt Edition): The friends look at two papers that looks into what old animals that are long dead would eat. The first paper looks at the teeth of a group of animals that move through the water like waves and have a long back part. Animals in this group today eat lots of different things. In the past, we do not know what these animals would eat so we do not know the ways in which these animals have changed to better eat the things they eat. This paper finds an old animal with teeth and body parts and finds that this thing could break hard things with its teeth, but also that it moved through the water in a different way than the animals today that break hard things. The second paper looks at hard things in the stomach of an

The gang discusses two papers that use Blender 3d modeling techniques (and other functional morphology techniques) to study arthropod morphology. The first paper looks at trilobite enrollment and the second paper looks at the anomalocaris great frontal appendages. Meanwhile, James likes horses, Amanda has some name ideas, and Curt fails to segue.   Up-Goer Five (Amanda Edition): Today our friends look at two papers that talk about things with legs that have many parts. The first paper looks at very old pretty large things with mouth legs that people can't decide if they were strong or not strong. The paper does lots of computer stuff to figure out just how strong the mouth legs are. They find that the mouth legs are not as strong as people thought they might be and so they did not eat things with very hard parts, probably, but things that were not hard at all. The second paper looks at how cute little things with legs that have many parts might have made themselves into balls. There are many ways that th

The gang discusses two papers that looks at mammal jaws and teeth. The first paper uses many different analyses to study how the mammal jaw evolved, and the second paper looks at a unique set of teeth in a fossil whale group. Meanwhile, Curt gets ideas from Mortal Kombat, James has discusses farming practices, and Amanda finds any excuse to be fabulous.   Up-Goer Five (Curt Edition): The friends talk about two papers that look at how mouths for animals with hair have changed over time. The first paper looks at the bottom hard part of the mouth to see how it first started and how it has changed and why it changed. Lots of people have ideas about this, but this paper is the first attempt to really look at this problem for a lot of different ways of handling it. They do a lot of things that are very number heavy to look at how these hard parts are able to move, and they look at a lot of parts from living and long dead things. What they find is that the bottom mouth parts of animals with hair are not as g

The gang discusses two papers that look at examples of unusually large animals in the fossil record; one large lacewing larvae and one very large skink. Meanwhile, James is having a great day, Amanda starts a chant, and Curt learns the true meaning of “cool fossil bro”.   Up-Goer Five (Curt Edition): The friends look at two papers about things that are big for what they are. The first paper is a type of kid of an animal that is small thing that flies when it is grown but does not fly when it is a kid. These animals have a neck when they are kids which some of these animals do not have. This animal has a really long body and a really long neck. They found it in water, so they think this animal would have been a big thing living in the water and eating things that it caught with its long neck. The second paper looks at another group of animals with cold blood and hard bits on its skin that runs around on four legs. This animal is really big for its group. Parts of this animal were found before, but they were s

The gang discusses two papers that look at the ecomorphology of Mesozoic swimming reptiles. The first paper investigates swimming strategies in various marine swimming reptile groups, and the second paper looks at changes in the skull of mosasaurs compared to stem whales. Meanwhile, James has a meal, Amanda “makes” animals, and Curt needs more insight.   Up-Goer Five (Curt Edition): The friends look at two papers that look at how big angry animals that move through the water lived a long time ago. The first paper looks at how these big animals moved through the water, because there are many ways that an animal can move through water. They use numbers to look at how these animals look, and they also use some animals from today that move through water to see if the way they look is like the ones from the past. They find that there are some ways that animals look with their bodies that change how they move through the water. This shows a lot of cool things. Some groups start moving through water in one way and

The gang discusses two papers that look at the impact of humans on bird populations. The first paper looks at the history of a condor nesting site in the Andes, and the second paper looks at the impact of artificial light on the circadian rhythms of urban bird populations. Meanwhile, James is highly engaged, Curt tries to sell some property, Amanda finds something slightly more horrifying, and everyone is in the presence of ALAN.   Up-Goer Five (Curt Edition): The friends look at how people have made life different for small  animals that fly in the air and some of them make sweet sounds. The  first paper looks at the home for one type of these animals that is  pretty big and eats things that are dead. These animals have been using  this home for a really long time, and we can look at their shit (yes  this is the only word I can use) to see what they ate in the past and  also see how long they have been there. A long time ago, their shit  shows that they ate a lot of things from the big blue wet thing,  prob

The gang discusses two papers that study the paleoecology of the Ediacaran fauna. The first paper looks at environmental information that can be gleaned from the microbial mats these organisms lived on, and the second paper studies how different Ediacaran fossils are distributed on this microbial mat. Meanwhile, James is having a week, Curt is unsure about chips, and Amanda is comfortable being very on brand.   Up-Goer Five (Curt Edition): The friends look at two papers that study some very old animals that lived a long long time ago and lived on these beds of tiny tiny tiny animals and not animals. In fact, these two papers are also interested in the beds these things lived on and how they lived on the bed. The first paper looks at these parts of the beds and how you can find them in different beds made of tiny tiny tiny animals and not animals. There are these lines in the beds that are found in some beds but not all of the beds. They think that the way water moves over the beds may cause these lines to fo

The gang discusses two papers about inferring life habit and ecology from extinct animals. The first paper summarizes the data for ichthyosaur birth to see if they really do preferentially come out tail first, and the second paper investigates a fossil that could complicate the narrative for the origins of a European sabretooth cat group. Meanwhile, James has opinions about browsers, Amanda is camouflaged, Curt needs a drink, and everyone is surprised by a paper for the first time in a long time.   Up-Goer Five (Curt Edition): The friends talk about two papers that looks at how animals did things and where they lived in the past. The first paper looks at a group of animals that lived in the water and had their kids inside them. This group used to be on land before they went into the water for all time. Lots of people say that when a group of animals goes from being on land to being on water, they need to change the way the babies come out of them, with the head coming out last so that they do not breathe in

The gang discusses two functional morphology papers. The first paper looks at eye placement and skull morphology in Thylacosmilus and the second paper looks at the ungals of maniraptoran theropods. Meanwhile, James has milk filled “vegan” food, Amanda is replaced by alternate universe goatee Amanda, and Curt looks to rebrand.   Up-Goer Five (Curt Edition): The friends talk about two papers that look at animals who have very strange parts and how they may or may not have used those parts. The first paper looks at a group of animals with long teeth that eats other animals but is not close to the animal group with long teeth that we all know. This group got long teeth on their own and through a different way. This paper looks at their heads and shows that the way they got long teeth changes how their eyes are put into the head. Most animals that eat other animals have eyes that face forward, this helps them see how close things are in front of them. The long teeth of this animal pushed the eyes to the si

The gang discusses two papers that look at patterns of niche conservatism or niche evolution in the fossil record. The first paper looks at the pollen records of trees in Portugal to test if changing climate can explain modern tree distributions, and the second paper looks at the impact of Late Devonian extinction pulses/invasions on brachiopod communities. Meanwhile, Curt summarizes the podcast, James has brachiopod facts, and Amanda cannot control her cats.   Up-Goer Five (Curt Edition): Our friends talk about two papers that look at where animals live and what they do in the world, and also if that stays the same or changes over time. The first paper looks at tall living things that make their own food and lose a part of themselves every fall. This looks at one place that has just a few of these types of living things but in the past there were different types there. Also, back then it was not as warm and the rain was different. This paper wants to see why the tall living things we have in this part of th

The gang discusses two papers that look at some Cambrian problematic fossils and find new clues that allow us to determine what groups they might belong to. One paper finds new evidence that some of these tube fossils in the Cambrian may be cnidarians and the other paper identifies potential gastropod radula in Cambrian rocks with adaptations for grazing. Meanwhile, James is not at all tired, Amanda will totally clean out her garage, and Curt is in the loop about what is going on.   Up-Goer Five (Curt Edition): The friends talk about two papers that look at some things from a long time ago that are very hard to see what is going on with them but these new finds give us a better idea of what they might be. The first paper looks at these long and soft things. We used to think they were long and soft things that live in the ground today. However, this paper finds that there are little arms on one side and that they have these parts that we see in a very different group of animals that instead has one way in tha

The gang discusses two papers that use morphometric studies to investigate patterns of ecomorphy in the fossil record. Specifically, they look at two papers that investigate how morphology in sloths and pterosaurs changes over time, and how well these changes map onto changes in body size and ecological shifts. Meanwhile, Amanda could be dean, Curt has opinions on figures, and James provides butchery advice.   Up-Goer Five (Curt Edition): The friends talk about two papers that look at how things look and how that changes over time, and looks to see if these things are changing because of what they do. The first paper looks at animals with hair and long arms that move very slow. There are not a lot of these animals today, but in the past there was a lot of these animals and they did a lot of other things that we do not see them do today. These animals were also looking different as well. But it seems that the things that look different are closer to each other by being close sisters to each other. They also d

The gang discusses two papers that look at the body size of ancient animals. The first paper uses new metrics to estimate the size of the ancient fish Dunkleosteus, and the second paper looks at the various ways that theropod dinosaurs can get big or small. Meanwhile, Amanda is 10 minutes away from being taken to Oz, Curt invents a new adaptation, James figures out perpetual energy, and everyone is forced to record over a conference call.   Up-Goer Five (Amanda Edition): Today our friends talk about a large animal that lives in water with no legs but a big mouth and moving mouth pieces and a hard outer cover. This big animal was one with a hard part in its back that ate lots of things very early before many other things with hard parts in its back were around that ate other things. People used to think that it got very very very big but this study uses numbers to show that it was actually not as big as people used to think. The numbers are very good and are probably going to be very good for lots of animals

The gang celebrates their 10 year anniversary by talking about two papers on the same topic that are 10 years apart. Both papers take a critical look at how we define the “big five” mass extinctions and what this term means. Meanwhile, everyone waxes philosophical for the last 20 minutes, discussing how things have changed in our lives since we started this weird show. Thanks for listening!   Up-Goer Five (Curt Edition): Our friends talk about two papers that were written ten years from each other. Both papers look at times when a lot of animals died. The first paper is looking at how these times changed the types of animals that were around after the big dying, and it finds that some times that didn't kill as many animals had much bigger changes in the types of animals around than times when a lot more animals died. The second paper continues this idea to ask, why do we look at the big times that we do and is there anything about these times that make the all the same. What do these times mean?   Reference

The gang discusses two papers about trilobite evolution and morphology. The first paper looks at disparity and taxonomic trends of trilobites across the Devonian, and the second paper looks at the unique tridents of Walliserops. Meanwhile, Amanda makes a choice, James does some unique functional morphology, and Curt critiques tilapia.   Up-Goer Five (Curt Edition): The friends talk about two papers that look at small hard animals that live in the water and some of them can roll into a ball. The first paper looks at how these animals looked over time. They look at whether or not these animals looked more different when there were more different types of these animals around. This is not usually the case, for lot of animals how different the animals in the group look to each other is not just because to there being more types of animals. For this group that some can roll into a ball, it seems like they look a lot more different when there are also a lot of different types of them. So when something kills a lot

The gang discusses two papers that look at how species respond to climate change. The first paper uses models to study how bird migration patterns may have changed over the last 800,000 years, and the second paper looks at how blooming times for plants in the UK have changed over the last 300 years. Meanwhile, James and Amanda prepare for a trip (2 months ago), and Curt is left a little confused.   Up-Goer Five (Curt Edition): Our friends talk about two papers that look at how living things can change when it gets hotter or colder across the world. The first paper looks at animals that can fly and some of them move around when it gets hot or cold during a year. This paper uses computers to look at how these animals may have changed how they move around during times that were colder and warmer than today. This is part of a bigger story where some people think that these animals moving around during the year is something that might be pretty new, since the last time we warmed up. The computers say that these t

The gang discusses two papers that look at live birth in squamates. The first paper is fossil evidence of live birth in an ancient snake species, and the second paper looks at the evolutionary pressures that might drive some lizards towards live birth. Meanwhile, James has advice for reptiles, Curt celebrates a belated “spooky season”, Amanda continues to have extreme face blindness, and we are all haunted by a corrupted PDF.   Up-Goer Five (Curt Edition): Our friends talk about animals that have cold blood but also have babies inside of them. The first paper looks at some old animals that have cold blood and no legs that have babies inside of them. These parts of the old animal with babies inside of them might be one of the first times that this has been seen for this group at this time. It raises some interesting questions about how and why these animals that most do not have babies inside of them might change to having babies inside of them. One thought was that maybe this happens when these animals with
