Palaeo After Dark

We ring in the new year by talking about new research on the evolutionary history of early animals. Also, Amanda makes some very deep cartoon cuts, James manages an emergency, and Curt makes impossible resolutions.  References: Pisani, Davide, et al. "Genomic data do not support comb jellies as the sister group to all other animals." Proceedings of the National Academy of Sciences 112.50 (2015): 1...

In this episode, we discuss two papers about early tetrapods/tetrapodomorph taxa, Tiktaalik  and Ichthyostega, and what new findings suggest about their locomotion. Also, Curt makes a suspicious delivery, and James desperately tries to feed Amanda "spoilers" for the new Star Wars. EDITOR'S NOTE: While I cannot confirm that any of James's spoilers are indeed accurate, they seem highly unlikely to b...

In this episode, we discuss two papers that describe ammonite feeding habits. Meanwhile,  Amanda gets into a boxing match, Curt is introduced to Moon Moon, and James is completely derailed by an animal.... again. Also, James invents a completely ridiculous life strategy  for ammonites (34 :30) that Curt is just drunk enough to truly appreciate.  Simple text summary The groups looks at two papers t...

Fresh off of GSA, the gang gets together to discuss a quick paper about the extent to which adaptation can overprint historical signal in evolution. Afterwards, James and Curt update Amanda with the highlights of GSA. Meanwhile, Curt explains quarter based economics, James hosts a quiz show, and Amanda is delighted by a paper.  "Your Call" Kevin MacLeod (incompetech.com)  Licensed under Creative C...

It's that time of year again, so James and Curt bring you day by day coverage of the 2015 Geological Society of America meeting, joined by friends Brendan Anderson and Tory McCoy. So join us for an ethically compromised good time as they discuss the fascinating work of strangers, friends, and themselves. Day 1: James and Curtis Day 2: James, Curtis, and Brendan starts at 0:50.40 Day 3: James, Curt...

The gang discusses two papers that deal with the events that led to the extinction of the early metazoan Ediacaran fauna, as well as the extinction's philosophical ramifications for our understanding of evolution in general. Chaos runs rampant throughout this podcast as our figurative and literal systems break down through time. But somehow, life.... finds a way.... through a 4G network. Meanwhile...

The gang finally just does what comes naturally and discusses two papers about food. Specifically, one paper on why things aren't tasty and another answering the vital question "what foods in the past would be kosher" (the answer might just surprise you). Meanwhile, Amanda finds her spirit animal, James details our terrifying corporate future, and Curt wants to play a game.  TRIGGER WARNING: Mild...

The gang discusses two papers about the evolutionary placement of some Cretaceous flowering plants (angiosperms). Meanwhile, Amanda finds her alter ego,  James goes very old school with his jokes, and Curt really doesn't want to talk about the next paper.   References Friis, Else Marie, et al. "Archaefructus–angiosperm precursor or specialized early angiosperm?." Trends in plant science 8.8 (2003)...

The gang discusses two papers that detail how the stratigraphic record affects our understanding of the fossil record.  Meanwhile, Amanda gets very enthusiastic, James burns straw men,  and Curt isn't sorry.   References Benton, Michael J. "Palaeodiversity and formation counts: redundancy or bias?." Palaeontology (2015). Holland, Steven M., and Mark E. Patzkowsky. "The stratigraphy of mass extinct...

In this episode the gang tries to have a discussion about the fossil preservation of birds. Instead they get completely sidetracked imagining the penguin apocalypse. Meanwhile, Amanda slowly goes crazy, James keeps hearing things, and Curt delights in a mispronunciation.   "Up goer five" text summary This time the group looks at papers about how animals that have bits that mean they can fly break...

The gang goes broad and tackles two papers that deal with evidence of sex and reproduction in the fossil record. Meanwhile, Amanda goes method, James invents a new scientific term, and Curt is haunted by one terrible joke that will not die.

The gang discusses two papers about the evolution of quadrupedal lifestyle in ornithischian dinosaurs. Also, James discusses the joys of being a squid, Curt details the ideal political tag-team match,  and Amanda dreams of HD belts. "Up goer five" text summary The group talks about big angry animals without hair - again. This time they look at two studies that look at how one group of big angry an...

The gang discusses two papers about the evolution (and loss) of hypercarnivory in mammals. Meanwhile, Amanda shares more equine history, Curt does his best to kill a trend, and James goes "nuclear".

The gang discusses two papers about the effects of the Permian Mass Extinction on the evolutionary and ecological patterns of brachiopods and bivalves. Also, Amanda finds her true calling, James indiscriminately throws shade, and Curt feels the pain of being the only person to vaguely remember what the papers were about.  'Up goer five' summary: The group talks about two types of animals with hard...

That gang discusses convergent evolution and potential sexual selection in the horns and frills of ceratopsian dinosaurs, which Amanda refers to as the "most American dinosaur". Also, Amanda defends a cause, James practices being a "tiger mom", and Curt drinks for two with disastrous but expected consequences.

In this episode, the gang discuss the diverse and ecologically abundant mammals of the Mesozoic. Meanwhile, Amanda gives dedicated fans an exclusive cat report, James learns something, and Curtis does his best Skeletor impression. However, the greatest question goes unanswered: what are Wombles? Up-Goer Five podcast summary (using only the ten hundred most commonly used English words): The group t...

Amanda thinks about a writing style. James takes on a big responsibility. Curt deflects. The nature of change is considered, but the conversation remains locked in stasis.   References Gould, Steven J.. "Is a New and General Theory of Evolution Emerging?" Paleobiology, 6.1 (1980): 119-130. Hunt, Gene, Melanie J. Hopkins, and Scott Lidgard. "Simple versus complex models of trait evolution and stasi...

In this episode, the gang discusses changes in biomass through time. They also spend a fair chunk of the podcast passing blame. Meanwhile, James is denied eating a bagel, Curt describes complex biodiversity patterns as “getting swole”, and Amanda apologizes repeatedly. They also try to answer the toughest question of all, would a eurypterid be tasty?   References: Bambach, Richard K. "Seafood thro...

In this episode, the gang tries desperately to talk about a really interesting plant paper and fails miserably. Meanwhile, James stops caring, Amanda relishes in being right, and Curt really tries to keep this one together (he fails). Also, despite the podcast not being about it at all, James has to talk about the new gliding dinosaur.   References: Stevenson, Robert A., Dennis Evangelista, and Ci...

 The gang attempts to discuss the Ringo Starr of mass extinctions, the End Triassic. And much like the actual extinction event, the discussion is long, broad, and not focused on any one thing in particular. Meanwhile, Amanda learns the joys of screen sharing, Curt makes some dubious shopping decisions, and James “wins” (play along at home and count how many times James “wins” the podcast).   Refer...

In this episode the gang discusses mimicry in the fossil record, which James uses as an excuse to introduce everyone to one of his “favorite” papers.  And as they stare into the gaping maw of mimicry in slack-jawed disbelief, grim smiling lips float back to them flashing pearly teeth in the dark and whispering one word.... mouths.   References http://www.edinburghgeolsoc.org/edingeologist/z_42_08....

The gang attempts to talk about the coral gap, but instead Amanda spends nearly 40 minutes trying to explain why Petoskey Stones are cool, and James tries to sidetrack her at every turn. Meanwhile, Curt is too drunk to care. Our sincerest apologies to all of the coral workers out there.   References: Robinson, George W., and Donald Reed.

In this episode we revisit the topic of taphonomy by discussing two papers that deal with actualistic taphonomy studies. Also, Amanda butchers potatoes, Curt becomes morbid, and James’s humor gets progressively bluer as the night goes on to the surprise of no one.   References Briggs, Derek EG. "The role of decay and mineralization in the preservation of soft-bodied fossils." Annual Review of Eart...

The gang returns to the subject of molecular clocks by discussing several papers that compare the results of molecular clock studies to the fossil evidence. Meanwhile, James tells stories of internet “fame”, Curt loses his composure, and Amanda will be right back.   References: Jarvis, Erich D., et al.
