That cryptocliudus and vampire squid paper was very interesting! As someone who has no connection to paleontology your videos are amazing and easy to follow, thanks for what you do
The huge gar is very cool, but they're really hardy fish, so not that surprising. The egg in an egg is really cool because, having chickens (and a few other egg-laying species), I know how rare this is. To have had a fossil egg in an egg found is SO lucky, it's mind-boggling!
They actually get overrated in some depictions (and even in academia), assumed to have outcompeted “inferior” predators that in reality managed to hold their own even afterwards, due to having supposed advantages like speed or pack hunting that amphicyonids never actually had in reality (amphicyonids were plantigrade and ambush predators, and there is no reason to assume they hunted in packs when most carnivorans do not)
I always look forward for your monthly reviews. so much info I have to watch it twice. your segment (near the end) concerning the fresh water ecosystems examined so close to the K-T boundary is quite interesting. alot of animals survived that event, and it makes you wonder just what the world was like after the impact. thankfully, the little mammals hung in there, or so much for us!
Well worth a thumbs up, Ezekiel. Perhaps the plaudits should really go to the authors of the papers, but the whole is definitely greater than the sum of the parts, so that's down to you. Every topic was fascinating in its own right, but as a one-time British resident, I must say, the thought of a giant Spinosaur galumphing around my former haunts was especiallly spine-tingling. And the reminder that my teeth are modified fish scales, As is a peacock's tail. Wow!
There is data to indicate O. megalodon really was hunting other predators regularly and that the test isn’t biased due to predation on nursing juveniles; the life history of one smaller raptorial sperm whale from the Late Miocene indicates a similar life history to small dolphins (which are preyed on even as adults), having shorter lifespans but reduced time to sexual maturity and relatively fast reproduction….and this was on a raptorial sperm whale roughly the size of a modern orca, meaning that there was something swimming around in the Late Miocene that was killing and eating orca-sized predators often enough to pose a significant amount of evolutionary pressure.
@@RaptorChatter Megalodon’s Late Miocene heyday also was the heyday of cetaceans in raptorial predator niches (including megalodon’s infamous rival Livyatan, which was the same size as the shark excluding the largest female megalodon and probably the only serious rival it ever had). It probably wasn’t a coincidence-something was allowing such massive marine predators to be especially successful during the Miocene.
Nothing like fetus in fetu, though there are some fossils which have the fetus still inside of them. There are some abnormal morphologies which indicate things like arthritis, but that may also be considered a disease. No true chimeras, but some people have stuck different parts of different fossil animals together to try and get press. Archaeoraptor is a famous example of that.
Really interesting, and as always a great source of palaeo news for my biology classroom as well. Thought you might be interested to know that the VAK model (three learning styles) has been widely debunked from a neurological and pedagogical perspective, but it's about as tenacious a myth in education as 'March of Progress' in evolutionary biology!
That's probably how it happened yeah. Essentially as the eggs hatched faster and faster they would become retained inside the body, and then eventually disappear all together. In order to get nutrients the yolk probably fused with the inside of the womb, and then became reduced with the umbilical cord just being attached to the mother.
@@RaptorChatter Dang! That's a fascinating aspect mammal evolution that I hadn't considered before. Thanks for the insights and great content my friend.
My favorite game ever. They got a lot of the simple things wrong as far as morphology and physiology, enough to drive an amateur Paleo-buff, like me, crazy. An educated pro would likely not like it. But it is a great game, within itself.

Glad you enjoyed it! And that's our goal, to keep every one able to keep up with what's new in paleontology.
That shirt is sick.
many lizards also keep the "belly button" such as many gecko.
Spinosaurids and abelisaurids always do continue to Suprise ! They always came up with gigantic species

the Amphicyonids definitely deserve more attention in media.
Gatty croc I completely agree with you on that.

They really should. I think I've seen them in a few documentaries, but never as a focus.

This being my brithday month I absolutely love this video and this one
Hope yall have a good day

I love the Bowler-Hat Giraffe much more than I should.
Thank you for the content, absolutely love your videos and learning about new things :)

Thanks for the compliments! And yeah, the British spinosaur is super interesting for their evolution, it's just they're always so poorly preserved.
Love to see it
They have to named this gigantic European Crocodile Faced Dinosaur later.
Euro crocosaur

That's really interesting! I'm not super knowledgeable about whale evolution, so I appreciate the insight!

Do we have any fetus-in-fetu fossils?
Any abnormal morphology beside injury or disease?
Any chimeras?

@@RaptorChatter What about the two-headed Hyphalosaurus fossil?
I can imagine Discokeryx was the only one where the male said: "Not today dear, I've got a headache."

Oh, I wasn't aware. Good to know for the future!
I would like to know what was going on in South America at the Permian/Triassic border, it appears that's where Dinosaurs truly started.
Yeah, there's still a lot of research going on there, so hopefully something will be published soon.
So do we know if the umbilical cord evolved from that attachment within the egg?
That's probably how it happened yeah. Essentially as the eggs hatched faster and faster they would become retained inside the body, and then eventually disappear all together. In order to get nutrients the yolk probably fused with the inside of the womb, and then became reduced with the umbilical cord just being attached to the mother.

@@nishbrown facts yeh something's could have been changed but otherwise it's one of my favorite games ever
Tbh I hate how palaeontologists can name species off say a partial jaw. You should really have at least ~70% of a specimen to name it
