There was tons of stuff to check out in Feb. 2023. So for most of the best see it here! There's fossil turtles, dinosaurs, crocs and more!
I definitely thought I had another button on done on that shirt.

Man, that climate map(s) is so awesome. As a kid through to adulthood I always wished there was something like this so I could get a better idea for the environment around these amazing creatures. There’s so much lost to time that we could only speculate on, but when things are in many many disparate papers you can’t really get this kind of workable understanding until you’ve had years of being an avid enthusiast. But potentially now, we can show kids like my son these maps. So now, just like when you describe an environment in current time and the person listening is at least most of the way toward picturing the environment right, we can do the same (potentially) for certain parts of deep time. So cool

Ikr? It seems like there's a lot of meta analyses rn, and it's great

Scotese has done some really great paleo continent reconstructions, and was a coauthor on this paper. So if you're interested I'd check more of his work, maybe Ron Blakey's work, and the other authors on this paper.

@waywardscythe3358 Жыл бұрын

those climate maps are really awesome to me. For some reason recently I got the desire to see what a real color world map of the Cretaceous would look like. Someone should make a google earth for dinosaurs where you can plop down anywhere and see a plausible render of the landscape and local flora/fauna.

There is a huge lesson from Dunky, it is really easy to make great big mistakes from incomplete data. There are people out there who are amazingly good at reconstruction, still its a reconstruction from partial data.

There's two kinds of people, those who can extrapolate from incomplete data.

I just want to say that I really appreciate the straight forward informational manner inn which you present your videos. I get so tired of people on KZfaq making pseudo-educational videos for people with short attention spans. Your channel is the absolutely best paleontological channel I've found.

I really appreciate these monthly summaries of paleo papers. I used to browse the Dinosaur Mailing List, but after it changed up so much, I was without a free source of new paleo knowledge until subscribing to this channel. Also, the point about field experience cannot be understated for young people wanting a paleontology job. As much as I've been enthused about paleontology for most of my life, the complete lack of field experience ruined my hopes of getting a job in that field.

@RaptorChatter Жыл бұрын

Yeah, there's definitely opportunities without field experience, but they are very rare. Hopefully as more people with disabilities which limit field work get into geology that'll change, but for now it's a lot of luck to get a position without that field experience. Glad you like the monthly reviews!

It's so funny that your reassurance on the Dunc update is, "Don't worry, it would still eat people." We're very attached to our childhood visions of murderbeasts sometimes.

Walking in Griffith Park in L.A. you might find dried coyote poop and if you examine it you may find little mouse bones and seeds the size of cherry pits. There are marine fossils in the Malibu Hills. We have a 60-mile-long mountain range that is virtually unexplored by paleontologists. L.A. is ripe with fossils. Don't get me started on the 'Pits.

The Angiosperm stem-group is according to multiple molecular phylogenetic studies the earliest diverging extant spermatophyte (seed plant) taxa. So no they didn’t came from nowhere. And also crown group angiosperms evolved in the jurassic so quite a bit more than just tens of millions of years before the upper cretaceous.

I love your videos - to the point, nice to listen to and no excessive and unnecessary jokes. I love me a good joke, but sometimes you just want facts. Thanks for your efforts!

Lol taking a page out of Ibrahim's book perhaps? Spinosurus, the gift that keeps on giving! 😂

@RaptorChatter Жыл бұрын

I know at least one of the tooth paper authors has been a coauthor with Ibrahim before, so it's not too out of the realm of possibility.

That was a busy month, and a nice job compiling so many news items! I wonder, however, if you might devote some time to explaining what goes into taxonomic regrouping. Because the vast majority of fossils are classified based on the morphology of hard body parts - often fragmentary and incomplete - it would be interesting to hear what sort of evidence if sufficient to convince the scientific community to reclassify a species to a new species, genus, or family. That probably doesn't deserve a video on its own, but perhaps an extra minute or two in the future video.

@RaptorChatter Жыл бұрын

I've been thinking about just doing a taxonomy video before, so then I can just point people to that for my videos if they're more interested in how those distinctions are made. I should really get to it sooner rather than later.

What are the holes highlighted in the Podocnemis tatacoensis illustration for? I am unable to find the answer.

@RaptorChatter Жыл бұрын

Those are foramen for musk glands. So the glands would sit deeper, and would get expressed through ducts which ran through those holes.

Say dude saw a bit out here on a very recent discovery of an ichthyosaur fossil dating from the very early Triassic with characteristics that point to its line evolving in the late Permian. Can you update us on this? Which while on the subject how is the termination of the Permian calculated? While I realize that the images of the late Permian with all the dead things laying around are for artistic effect, it seems to me that actively evolving 'fish lizards' would tend to indicate more healthy environments than usually associated with the extinction.
