Episode 204 - The Messinian Salinity Crisis
Around six million years ago, the Mediterranean Sea dried up, wreaking havoc with local marine life and leaving a dramatic legacy in the geologic record in the form of massive salt deposits. This episode, we’ll explore the evidence for this event, why it happened, how it ended, and the impact it left in the fossil record.
In the news: marine crocs, giant cicadas, giant tadpoles, and drowning bats.

    Some dogey maths in the news about the eggs. 3 square meters is 32 square feet. When converting squared units you have to do the conversion twice. Not sure if that was your mistake or straight from the paper. 6:30

    18:10 Aren't anurognathid pterosaurs hypothesized to be aerial insectivores though (e.g. Evolutionary pressures of aerial insectivory reflected in anurognathid pterosaurs by Hone et al. 2023) ? Additionally, they seem to even be in the right times and places to enter arms races with palaeontinids. Are there Mesozoic birds hypothesized to be aerial insectivores living with giant cicadas?

    • @commondescent

      This is a great point! The diets of early birds aren't well understood, but anurognathids have been hypothesized as aerial hunters of bugs.

    With the convo about animorphs and KA Applegate- it may interest the community to know that the character Jake was named after Applegate’s then-son, now daughter (whose new name I do not know). Anyway, the point is Applegate has a trans daughter, and is very supportive of her.

    Hi guys, big fan of the podcast btw! This spec-evo of the Jackalope got me thinking about all the different inspirations for the Jackalope. Like on the deer side, there’s Asian water deer, pudu, brocket deer, muntjacs (which have antlers and tusks!), tufted deer, and that’s just the true deer. Then the bovids have duikers, dik-diks, klipspringers, royal antelope, four-horned antelope, steenbok, and oribi. Then there’s the chevrotains and musk deer, not to mention the extinct artiodactyls. One angle I kind of like is the idea of the Jackalope being a species of dwarf pronghorn, Capromeryx, that survived past the ice age. Great stuff you guys do!

    So the problem with mammoths being a negative 1. We never saw them 2. This is the way the world is now. 1. We probably did see them quite a bit, a lot of bones have been found with tool marks. 2. Spruce and firs roots go down 3 feet, tundra grass goes down 30 feet. Wanna talk about problems? Global warming coupd be our fault not because of pollution but because killed the mammoths either directly or indirectly through claiming territory. Mammoths like african elephants today pushed down trees to create savannahs they forage on as well as to eat the trees, thats the difference between borial forests and tundra then and by bringing mammoths back and returning the borial forest to tundras we may reclaim the fertile tubdra enviorments creating massive carbon sinks and reverse global warming. Now what happened immeadiatly after the mini ice age, the black plague....so plague plus healthy planet vs no plague plus different planet thats the question with mammoths.

    Working my way through the back catalog. If you're still interested in great movie scientists, I'd like to propose Dr. Clayton Forrester from the 1953 movie War of the Worlds. His colleagues at Pacific Tech too. At the other end of the spectrum would be Dr. Arthur Carrington from 1951's The Thing From Another World and his colleagues too. There's also the whole team from 1971's The Andromeda Strain, who show what Michael Crichton can do when he's working on the field he was actually trained in. Maybe classic sci-fi movies for a Silver Screen Science series?

    WHAT IF! For when they are mogwai, the multiplying is not the offspring, but just the other younger/smaller Mogwai clinging to either an older sibling or some other individual. Same applied to the matured Gremlin state.
