Podcast 285 - All Things Big and Small
Palaeo After Dark
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...

Podcast 284 - How Complete Is Your Shark
Palaeo After Dark
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...

Podcast 283 - Stolen Podcast
Palaeo After Dark
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...

Podcast 282 - Early Fishies
Palaeo After Dark
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...

Podcast 281 - Climate and Extinction
Palaeo After Dark
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...

Podcast 280 - Just a Weird Little Guy
Palaeo After Dark
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...

Podcast 279 - Frogcast
Palaeo After Dark
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...

Podcast 278 - The Wrong Shapes
Palaeo After Dark
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...

Podcast 277 - Bird Tracks For Fun and Profit
Palaeo After Dark
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...

Podcast 276c - In the Woods Somewhere Part 3
Palaeo After Dark
A cleric, a wizard, and a paladin finally make their way into the center of the woods. What will they find at the end of their journey? "The Builder", “The Other Side of the Door”, “For Originz” by Kevin MacLeod (incompetech.com) Licensed under Creative Commons: By Attribution 4.0 License http://creativecommons.org/licenses/by/4.0/
info_outlineThe 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 do find that these animals are also doing different things when they look different.
The second paper looks at angry animals who can fly but are not the animals that can fly today. These animals start small and get big over time. They actually get big a few times. This paper looks at the parts of these animals and shows the many different ways that parts can change to make these animals big or small. It also shows that, when these things get really big is when the group seems to be doing really bad.
