Yeah people don't realize that mammals and our relatives were quite diverse during the Mesozoic Mammals were hit quite hard in the end Cretaceous extinction
@@Egill2011 dinosaurs didnt go extinct, birds are still here. Most mammal clades also went extinct. most mammals and dinos went extinct, but the few that were left led to the mammals being better adabted to be megafauna
To be fair, I remember loads of nature documentaries as a teenager that basically said that. They implied that reptiles evolved into mammals after the asteroid strike in order to have the warm blood and brooding behaviour to survive in low-sunlight environments
@@gregoryfenn1462 Mammals evolved during the Jurassic, which is 10's of millions of years before the asteroid, tens of millions of year before any tyranosaurid, tens of millions of years before any ceratopcian existed, tens of millions of years before any troodon ''raptor'' evolved. Before dinosaurs, in the permian era, early mammals ruled the world, we call them therapsids
Noticing a pattern : animals whit digging adaptation can transition to water very easily : other than the platypussy and the castorocauda we have some beaver ancient relatives wich had a digging lifestyle , the star nosed mole can swim in water , otters come from the mustelid a group of manly fossatorial hunters and nearly all Xenarthra can swim . Guess having shovel paws and the ability to hold the breath for long time helps in swimming
@@matthewdodd1262 true also snakes probably had a similar history : pepole are currently indecise wheter they were digging lizard or swimming lizards iparentetad whit mosasaurs
currently my favourite channel. I'm deeply inerested in zoology ever since I was a little kid. Now when I finally know english, there's so much more to discover. Thank you for your work guys. I'm thinking to start helping you with your work from artistic side of it. I'm a painter and a graphic designer and when I finish animation project I am currently working on I would like to start painting animals for you some times 'pro publico bono' - of course.
Thanks Ben, great video! I had to go look up wth a Docodont was. Apparently they branched off before even the monotremes did, and are thus not even mammals. One called Patagonia survived in South America until at least the Miocene. It's crazy to me that South America was such a repository of deeply-branching mammalian diversity at that time, including true placentals, true marsupials, various metatherians, and even this Mammaliform group. How did all these groups manage to make it to South America, and yet remain isolated from the rest of the world to survive? Would be great to have a video on these different waves of colonization over South America's geologic history
Thanks, you are definitely broadening my mind. I had stopped exploring the evolutionary story because I thought I had a general grasp of the subject, but you constantly surprise me with these more specific examples I'd never heard of nor suspected. I am sure a deep interest drives your efforts, long may it remain.
The claws would also indicate that it may have dug for shellfish. Eat fish meat they would also eat shellfish meat. Pointy face to poke into shellfish burrows. Fat nose would easily detect any movement, dig the clam out. Fills the beaver niche. The second animal looks like the musk-rat niche filled.
It amazes me just how intertwined burrowing and swimming lifestyles have helped sculpt mammalian biology and anatomy over the millions of years since splitting from reptiles.
Well done! I really am enjoying the amazing quality of your presentation skills. It never get‘s old and I hate to admit it, but I am even more fascinated listening to you than to my zoology professor, so many ages ago 🤗👍
Strange not only to think that this existed with dinosaurs but was also a part of their diet. If I ever saw a dino eating one I'd yell "NO, THAT COULD BE MY ANCESTOR!"
I would love a video on the mentioned Platypus. A strange mammal with some unique adaptations... like eggs, a bill and venom? How is that not a literal monster...
I like the way how science give scientific names on latin most of the time. Im Beazilian and i can understand the name Castorocauda Castor in Portuguese is beaver And cauda is tail.
I wish I had a time machine so I could just watch all of these animals see them touch them maybe bring something no one seen before back with me imagine we still find animals alive on earth today it’s so hard to imagine what it would truly look like I wish I could see it all honestly it be so perfect
I find this very interesting. What 1st struck me as the host started talking about this animal being like a beaver or otter was would its physcial characteristics not be compared to a platypus. And what is mode of replication more like monotreme, marsupial or mammal. The artist's illustration made it look more like a platypus. This the host started talking about it's supposed prey being among other things including insects and it being built to dig. Here again the comparison to the platypus is valid. Duckbill platypus diet consist of crustaceans as well as aquatic insects and worms. Platypus is also built to dig either in bottoms of ponds & streams as well as into banks of streams or ponds. Would be interested if this animals also has a venomous spur on any of its legs?
Amazing, this adaptations show convergent evolution at his best. And 164 millions of years in the past!! hopefully in the future it could exist the big mesozoic ecology once again
Yet again taxonomy has me confused. So within the context of crown-group phylogenetics, if a species has no extant descendants, it can't be classified with its relatives that do have extant descendants? Would survival to the present day have been enough for castorocauda to be considered a true mammal?
I was going to say that you're too smart for your own good, but I'll amend that to your too knowledgeable for _our_ good. Why don't you restate your remark in a more digestible form. Pre-thanks in advance
Convergent evolution being such a common thing both in living creatures and fossilized remains leads me to believe complex alien life forms might not look as alien.
I love amphibious mammals like the platypus, and this Castorocauda is fascinating. 😊 By the way, do you have an opinion on Matthew Bonnan saying in a conference that Tyrannosaurus was a "clapper, not a slapper," meaning that the palms of the T. rex's hands always faced inward and toward each other, not facing the ground?
the ability to pronate one's hands is a Mammalian trait from Trechnotheria onwards (derived synapomorphy) It is caused by a process on the tibia that allows our lower arms to rotate. Dinosaurs didn't have this., nor do momotremes...
Yes, the Crown Group definition refers to the last common ancestor of all mammals alive today, and all descendants of said ancestor. Thus, animals that are not directly descended from that ancestor would not technically be considered true mammals.
Can you do a video on the large fauna early humans would have confronted as they spread around the world, maybe starting with the move out of Africa of Homo erectus?
Calling back to your vids on Speculative Evolution, I can't help but notice a similarity (of these AND beavers) to ancient whale-ancestors, and ponder a possible future Beaver-Whale. I suppose, in the long term, it would just look like another species of whale. But I find the image "Beaver-Whale" conjures up much more entertaining. (c:
Very cool! I really wonder if those guys were oviparous or viviparous. If the former, have the laid eggs like platypuses (which means they must have been only semi-aquatic and incubated their eggs in nests, unless they were more like sea turtles, which would be strange in a mammaliaforme linage). If the latter, how did viviparity evolve in docodontidae and what did it resemble.

We need more contents on Mesozoic mammals. Most people still believe that mammals just magically appeared after dinosaurs were gone.

Absolutely. Dinosaurs went extinct because mammals were better fitted.

Nice beaver.

Great video! I’m learning a ton
It looks so normal and familiar that trying to picture it in the same time as some of the strangest living things ever makes it seem like the odd one
I would love a video on the mentioned Platypus. A strange mammal with some unique adaptations... like eggs, a bill and venom? How is that not a literal monster...
Convergent evolution is cool. Here's this crazy guy doing the beaver thing millions of years before the first beaver.
Its skull looks like a shrew; its like a big aquatic shrew.
Imagine being named after a creature that lived millions of years after you
Am I the only who remembers this scrappy little bugger from dinosaur revolution?
TheGamingBeaver needs to see this
Excellent but did I miss where you showed exactly how it fits onto the Tree of Life?
Wow! Now this is kind of a chimera like the platypus but more mammalian.
I love this mammalian form, I remember it
I only remember this animal because of Dinosaur Revolution
Mammals have it again! Nice to know where we come from ( under dino claw).
Enjoyed it and gave it a thumbs up
I like the way how science give scientific names on latin most of the time.
Im Beazilian and i can understand the name Castorocauda
Castor in Portuguese is beaver
And cauda is tail.
I have one of these in my outdoor aquarium Doesn't everybody?

This is pretty much evolutions first attempt at a beaver
Why do its shoulder blades have such a shape? they seem to protrude upward, way higher than the nearby vertebrae. Why is that?

We finally found it! We found the gaming beaver!
wonder if this ancient ancestor to mammals could have been a monotrene (egg
laying mammal) like the platypus?
While they wouldn't have been monotremes, they likely birthed and raised their young in a very similar manner.
Probably. It is less mammal than monotremes.
Convergent evolution being such a common thing both in living creatures and fossilized remains leads me to believe complex alien life forms might not look as alien.
I love amphibious mammals like the platypus, and this Castorocauda is fascinating. 😊
By the way, do you have an opinion on Matthew Bonnan saying in a conference that Tyrannosaurus was a "clapper, not a slapper," meaning that the palms of the T. rex's hands always faced inward and toward each other, not facing the ground?

@@RichardRenes what conditions would have to be met for an animal to have pronated hands?
You should make more videos about Mesozoic mammals, some of them are awesome, like Cronopio for exemple.

Wouldn’t it be so cool if there was a fully aquatic member of this group? Whales before whales.
Well...pliosaurs mosasaurs and ichthyosaurs could be argued that where whales before whales
Wasnt there another giant beaver called castroides
Yep, although that was an actual beaver. :)
You mean that giant ice age beaver?

Iirc one of the earliest Mammals, Megazostrodon, already had features suggesting live birth. So it likely evolved in Synapsids first.
I came for the jokes. I stayed for the video.
If it was related to any modern mammals at all, then it most likely would be related to the platypus as the closest link to monotreme mammalss.
leave it to beavers
