Prehistoric Planet Croc Ideas

So this was a thing I did on Twitter in anticipation of Prehistoric Planet. Obviously crocs (in this case meaning crocodylomorphs) were a pretty massive part of earth's fauna during the late Cretaceous, and seeing as the first season featured NONE I came to speculate which taxa could hypothetically make an appearance. Now part of the challenge for myself was to come up with a new, interesting contender every day in anticipation of the show's release, each based around the confirmed episides we had and restricted purely to taxa from the Campanian and Maastrichtian. While it took a lot of energy, I did manage to do so. Hell, halfway through they dropped the reveal of Simosuchus, which I had saved for later.

Obviously we didn't get much still, but I'll regardless post my list of candidates and ideas here, perhaps third time's the charme for a lot of these (tho for convenience I'm still ordering them by S2s episode titles). I'll also try to break them apart roughly by biome, starting with islands. PS: I'd love to hear which crocs people would have loved to see themselves. Any on this list or stuff I didn't even mention? Let me know I'm curious.

We got a shit ton of island crocs from the Cretaceous actually, which you can broadly divide into two categories. The crocodiles of the European archipelago as seen in the top row. Featuring the small, possibly shellfish eating Acynodon (art by Adramelech89), the incredibly widespread Allodaposuchus which did have some possibly semi-terrestrial forms (art by Alejandro Blanco, Aina and Agnès Amblás) and Aprosuchus, a tiny terrestrial critter from Hateg (art by @knuppitalism-with-ue). They already give a nice diversity between tiny durophages with blunt snouts, large, more traditional crocs and lanky land species.

The other island category concerns Madagascar, which had a lot of attention in season 2. Discounting Simosuchus, we got Araripesuchus tsangatsangana (art by Scott Hartman) and Mahajangasuchus (art by Mark Hallet). Both are really cool. The former is yet another smaller terrestrial species that may not actually be part of Araripesuchus, while the later is a massive, 4 meter relative of the famous Kaprosuchus that took to the water independently from all other crocs and has been nicknamed "Hippo croc" for its weird skull. Really I'd have loved to seen an episode entirely dedicated to this place.

Next up we had the badlands episode, which oh boy has a lot of contenders from the clade Notosuchia. Brace yourself.

Here again I could split these in two categories. The first is just general badland taxa. There's Ogresuchus for example, from Spain's Tremp Formation (art by Aina and Agnès Amblás). A relatively small sebecid found in a sauropod nesting site. And we all know what PhP does with baby sauropods. Or the long-necked Gobiosuchus (art by @yoofilos) from Mongolia, which may look like its related to the other ones in this category but actually is a far more ancient type of croc.

The far bigger group concerns South America's Notosuchians. ALL OF THESE are from the Bauru Group, with some even from the same single formation. You got Stratiotosuchus (again by Joschua Knüppe), a large terrestrial baurusuchid that filled the nische of mid sized carnivore in an environment shared by sauropods and abelisaurs. There's Pissarrachampsa (by Felipe Alves Elias), another baurusuchid I decided to feature because we have evidence of a nesting site that shows they only had few eggs. A great opportunity to show their tender side. Uberabasuchus (justin_an74), part of the bizzarly proportioned peirosaurids. Adamantinasuchus (by Deverson da Silva), a small, lanky Notosuchian and of course the heavily armored omnivore Armadillosuchus (by the ever talented Júlia d'Oliveira). Hell you could do a full episode just on the foodweb of the Bauru Group (Godoy et al. 2014).

Then there's swamps, which I'll just use to dump all the crocs that don't fit into the other categories.

As you'd expect, freshwater would be ideal for crocs with a more traditional semi-aquatic lifestyle, here represented by three forms. Jiangxisuchus (image by Li et al. 2014) is a paralligatorid, which are tiny crocodilians from the Cretaceous and Paleogene of east Asia. We honestly don't know what they are, some say alligator relatives, others say they are closer to crocs. But its small and cute. Then there's Roxochampsa (artist of the model I couldn't find), which looks suspiciously crocodilian but is actually a relative of Uberabasuchus from the badlands, hell it appeared in the same formation. Still, I reasoned that I'd throw it into this category because I already proposed so much for badlands (none of which came true but hey). And then there's Denazinosuchus (art by Andrey Atuchin). Again it looks deceptively like a modern croc, but is actually the last remnant of the goniopholids, crocodyliforms that were prominent animals in the Jurassic and early Cretaceous. It could have brought both taxonomic diversity nad highlighted croc resilience till the end.

When it came to picking out crocs for Oceans, it got tricky. Obviously season 2 tried to differentiate itself by being set more in the open ocean, not the coast, and true pelagic crocodiles weren't around by the end of the Cretaceous. So I had to settle for coastal animals. There's Sabinosuchus (Schiller II et al. 2016), a cousin to Sarcosuchus and, like Denazinosuchus, one of the last of its lineage. Also its from Mexico which is rarely talked about for its fossils. Rhabdognathus (Ghedoghedo) is a distant cousin, a slender snouted dyrosaur. Unlike pholidosaurs, dyrosaurs actually did really well after the KPG impact and spread around a lot, living way into the Eocene. And finally Chenanisuchus (art by artbyjrc), which like Rhabdognathus was found both before and after the impact that killed the dinosaurs.

And the final two I shall talk about, both of which I thought/hoped would appear in the North America episode. Again, there's certainly overlap, both would have just as much fit into swamps, while many others would have also suited North America. Regardless, here's Brachychampsa (Tom Parker) and Borealosuchus (Chris Masna), both iconic animals from the Hell Creek Formation. One closely allied with alligators and caimans, the other more basal with a head-shape more similar to todays crocodiles.

Now obviously there'd have been a lot more. Part of the challenge to myself was to try and be as diverse as possible, rather than just listing 10 different baurusuchids I went with only two, tried to include as much of the world as possible, etc.... There's also the fact that some really awesome taxa, Titanochampsa, Brachiosuchus and Eurycephalosuchus, all incredibly unique or interesting, were published too late to have been considered for the show. And now, in hinsight, we obviously know that with the exception of Simosuchus none of them made it in. Which is a shame, but maybe next time.

How the brain’s immune system could be harnessed to improve memory

When it comes to memory, immune cells are known as the “bad cops” of the brain. But new research shows they could also be turned into “good cops” to power memory and learning.

Inflammation can send the brain’s immune cells into damaging hyperdrive, and this has been linked to neurodegenerative diseases that affect memory, like dementia.

In the new study, researchers at RMIT found that these same immune cells – known as microglia – can also be activated to have the reverse effect.

When the microglia were altered in rats, their performance in simple memory tasks improved by up to 50%, rather than deteriorating.

While the effect was temporary, the discovery suggests these cells could be targeted in the development of new therapies designed to enhance memory formation, with the hope of preventing cognitive decline as people grow older.

Worldwide, around 50 million people have dementia, with nearly 10 million new cases each year. In Australia, dementia and ageing-related cognitive decline affect 9% of people aged over 65.

Chief Investigator and senior author, Associate Professor Sarah Spencer, said the unexpected results of the study expanded our understanding of memory formation and the role of neuroinflammation in memory loss.

“Cognitive decline is a big problem for our ageing population, and we currently have very few treatments to treat or prevent it,” Spencer said.

“Even in healthy adults, optimising how well we learn and remember can give us a substantial performance edge at work and socially.

“Our study has for the first time shown a link between changes in the immune cells of healthy brains and improved cognitive function.

“While it’s early days and a lot more research is needed, we hope our findings may lead to new therapies that can stimulate these immune cells to boost memory and keep our brains powering as we age.”

Activating memory with activated microglia

In the study, published in Journal of Neuroinflammation, the researchers worked with a unique type of rat to test the effect of microglia on cognitive function.

The study looked at how the rats performed memory tasks when the immune cells were present and compared this with their performance when almost all the microglia were knocked out.

They found that removing almost all the microglia made no difference in memory tasks.

But when the microglia regenerated, this led to astounding results: researchers ran the same memory tests on the rats and they performed 25-50% better than normal rats.

Importantly, the regenerated microglia were a different shape - similar to the “activated” shape that these cells have when dealing with inflammation.

“We are still exploring what makes these cells different when they repopulate the brain, but their shape tells us they may be more active than usual, potentially making the neurons more effective to encourage better memory,” Spencer, an NHMRC Career Development Fellow at RMIT, said.

“The effect doesn’t last. As the microglia go back to their usual shape, memory performance also goes back to normal.

“The next stage in the research is closely investigating these regenerated microglia to better understand the mechanisms at work, with the aim of finding ways to turn the temporary memory boost into a long-lasting effect.”

Microglia-suppressing therapies are currently being tested in clinical trials in the US, as potential treatments for Multiple Sclerosis.

“With our new understanding of the role of microglia in memory, it may be possible in future to test the therapies originally designed for MS and assess their potential in improving cognitive function as well,” Spencer said.

it's okay to stray from your story. go write that short fic you can't take your mind off of! give you—and your characters—a break.

you! won't! always! make! your! word! count! -- you don't need to keep stretching sentences because the scene you finally got right is a hundred words too short. sometimes it's better that way.

the "rules" and "tips" are just ~guidelines~ (especially for people who like to swear by them) -- writing has no laws. especially first drafts. scrap the grammar, scrap the emotional tips, write it because it feels right, not because someone else says so.

every writer procrastinates. it's not easy being a writer.

take time off for yourself. the only thing harder than writing a story is to keep pushing it when you need a break the most. come back to it later. I promise there will be no dumpster fires when you're gone.

all writing is "real" writing. I don't think there's an explanation here?? fiction writers are writers. nonfiction writers are writers. fanfic writers are writers. (like how all reading is real reading!! in every format, too!)

it doesn't need to be perfect. honestly, it might never be. but it can be really close to it. if you're not satisfied with it, move on and come back when you're ready.

you are just as skilled as any bestselling author. remember that everything you read has been heavily edited by teams of people! their first draft could not even be as good as yours is now.

not using clichés is cliché. you will find one in any story. no one can bring you down for liking a certain trope. just because it's common doesn't mean it's bad!

no writer is fully well-rounded. dialogue will be easier to write for some, and description for others.

and, finally, no one knows what they're doing. trust me. we're all stumbling around blind here.

I wonder if the role of those two is ever going to expand at some point.

Uncharismatic Fact of the Day

Parrots are far from the only bird able to mimic human speech. Many other birds, like the crow or the mynah. Other animals like my personal favorite, the Macgregor’s bowerbird (Amblyornis macgregoriae), can even mimic other environmental sounds. Here’s a very cool clip from the Netflix documentary Dancing with the Birds, showcasing the wide range of the Macgregor’s bowerbird.
