Early Artiodactyls and Tylopods
Вставка
- Опубліковано 8 вер 2024
- Please enjoy this examination of basal Artiodactyls, which were surprisingly diverse and have a long evolutionary history. While some would have resembled modern ungulates, many genera were quite bizarre, looking like rabbits or even carnivorans.

The Artiodactyls as a whole are probably the most diverse non-controversial order. To highlight some of the diversity, the order includes tree-climbing almost cat-like herbivores, pig-like predators, ruminants and fully aquatic, colossal filter feeders and mega predators.
@@indyreno2933 why is it that you keep replying to my comments with inaccurate, extremely long responses?
Euarcontaglirens, Xenarthrans, and Afroferians are diverse as well

Just a reminder that "Indy Reno" is not a reliable or accurate source of zoological information. Much of what they keep stating and repeating is either outdated, not widely agreed upon, or simply completely made up. So you can safely disregard and ignore much of what they say, because they keep pretending that they know a lot about animals when so much of it is not even in the published zoological literature or mentioned by professional zoologists.
@@Reyma777 this person likes to do that, they have been called out plenty for made up and inaccurate information on this channel. I believe they have some issues.
@@indyreno2933 Dude I see you on every animal video. Stop spreading misinformation. Honestly I’m tired of correcting you on your outdated beliefs
Another great video.
You made a good point about academic paywalls too lol, really frustrating when trying to research really any of the non-dinosaur animals.
Thanks Doc. I had not heard of many of these fascinating animals, a lot of them don't look much like you would expect. Very interesting video.
Also that fossil at 1.17 is quite nice.
Looking forward to the kangaroos!
That last picture of the prehistoric kangaroo is truly something else
Wow! I never knew the tylopods had such diverse morphology in prehistoric times!
Bonus points for the correct pronounciation of the word "guanaco"!🎉
I did look it up just to be sure!
"Hello everyone, Dr. Polaris here"...
And your evening is rescued. 🥳
I ❤ your content so much. I learned with every episode a bit more. Just amazing! 🤓
Keep going Dude! 🦖
Me too!
Great video! Plus that last picture with the kangaroo about to grab that guy is horrifying.
This channel needs to grow big! So much info in such a simple yet elaborated manner. Kudos to Dr. Polaris ✌️ Lot's of love and support to you ❤️
Your comparative size depictions are fabulous, and give a useful visual reference for us. I hope to see more in other episodes. Wonderfully made doc!
I love this person's videos. They are very well put together and informative.
Would love to see a vid on the diversity of balen whales of the Miocene-Pliocene. Or one on the Cetotherium of which only one of the family is left.
Suggestion for future video: ant eaters - mammalian and dinosaur - shared morphology (including dentition) and what if anything termites and ants developed to counter them.
LOVE the "academic paywall" callout. I think a lot of folks would be happy to use their credentials to help you get articles though.
great video. you disserve more attention.
Incredible video, as always. Waiting for recent unknown stuff like vishnuichtys
This was GREAT!!!!!
It's interesting to me that Artiodactyls all started out of long thick tails, but none of the living species possess them today. True, whales do have long thick tails, but they use their tails for propulsion so don't really factor into this.
That is probably because all early mammals seem to have had long, thick tails.
@@scvcebc Yes. But what is curious to me is the fact that all the extant herbivore species above a certain size greatly reduced the size of their tails. Some kind of evolutionary pressure must have existed that caused long tails to either be a detriment, or unnecessary.
@@DragonFae16 Probably because unlike most sauropsids and early synapsids mammals don't "use" their tails to walk/run rather relaying in their limbs for propulsion. There are mammals who have long tails and are cursorial (like cheetahs) but they use their tail as rudder rather than a direct running aid.
@@indyreno2933 Whales are part of Artiodactyla aka Artiodactyls. I said in my comment that they don't factor in. I mentioned them in case someone pointed to them and talked about how they still have long tails if I didn't bring them up.
That aside, why did you feel the need to give a lecture about a plethora of species that don't even factor into the conversation? Did you just want to cudgel someone with your knowledge/googling skills? Your comment doesn't add anything constructive to the conversation. To be constructive, you would have had to add how each of those species/genera/orders factor into the discussion on the Artiodactyles greatly reducing their tails. Unless someone specifically asks for a full list of different genera, orders or families, a list like that is completely uncalled for. All you had to say was that they aren't closely related to living even-toed ungulates. No need to bring bats, shrews and the multitude of species up at all.
@@indyreno2933 And you must be bringing all those orders of mammals up because they are the ones responsible for ungulates losing their long tails. And here I thought it was the mermaid mafia because they had been paid with leprechaun gold.
Incredible video about a new awesome group of prehistoric fauna topic :D
And I wish you a great day
I am usually overwhelmed by this group, thanks. While whale evolution needs its own time slot, I've never been sure how they fit into the ungulates.
@@indyreno2933 in essence, orcas are the only ungulates that prey on carnivorans, seals

There used to exist carnivorous land ungulates as well like the mesonychians. I wonder if the land ancestors of whales were herbivorous or whether they were omnivorous like the 1st ungulates probably were.
Cool, fascinating! Thank you for bringing these. I REALLY am looking forward to kangaroos!!!!! Their method of locomotion is unique. I keep wondering what drove that? We know cheetahs drove gazelles and the American cheetah-oid drove pronghorns to their fast forms. What drove kangaroos?
@Marshal Marrs , Marsupial lions were deadly but they were ambush predators. They were the REAL drop bears of Australian legend. The komodo dragon has a top speed of 12 MPH or around 19 kph. I don't see the kangaroo form giving an advantage against either.
Interesting. Thank you
I really enjoy information about mammals from prehistory! Wonderful episode!

I hate how a lot of Paleontology papers are hidden behind paywalls like that.
It’s ridiculous!
If you want a dumb example, go to the sed-strat stuff.
There's one paper I know, from the 1960's, whose authors are long dead/retired.
Still behind a $60 paywall...
@@Albukhshi
You’re kidding!
That’s absolute bulls**t!
That Kangaroo picture at the end tho!
>Kangaroo: Now boy, you put down that spear!
>Aborigine: Welp, I'm f*cked.
at 1 point there was no clean cut between hooves and claws
Wow, that last pic is nightmare fuel! 😱
I saw comment on somewhere in social media, maybe in twitter, where scientist told that scientists don’t get money from their studies, thus they are willing to send their papers for free if asked nicely.
Very neat! Alsooooh FUCK YEAH KANGAROOS!!!!!
Great video! Eocene fauna is very underrepresented, some of these animals are very unique and interesting. Also I have question. Did made video about Deinotherium and its relatives? If my memory is correct there was one but now I cannot find it.
I did but it was copyright claimed and taken down.
@@dr.polaris6423 Shame. Will you do remake of it?
@@dr.polaris6423
Aren't some people miserable 😕
Here to catch up, and leave a like and comment for that ever-voracious Almighty Algorithm, and all that stuff. 👋🏼😁👍🏼
❤️❤️
Thank you greatly, it was really interesting!
wow Another great video
This was a great video! Can you make a next video about the Chapalmalania?
Oof bring on the kangaroos vid. Love your work mate.
I want one.
9:06 could Sespia have looked like a hoofed capybara, maybe? Because the capybara is a large relative of the guinea pig?
Heliosus
Super Nice
Thank you
Please make a video of Panthera Shawi, and their evolution into common leopards, Mosbach lions, today's lions, cave lions, American lions, and jaguars..
@@indyreno2933 -I'm not asking for the whole origin of felines, he already made a video that... I'm asking just for the one that gave way to today's lions, and closest relatives..

@@edwinreveron870 Besides, so much of what "Indy Reno" claims is outright false information; it's either outdated, or is even completely made up, like their attempted reclassification of Panthera - there's so much over there that is simply downright wrong and not recognised by professional zoologists.
I would like a return to your Alter-Earth videos, please.
Do you know when Cetaceans branched off from the rest of the artiodactyls

... Tide pods? No, I eat Tylopods (OOOOHHHHH!)
I'm sorry.
Also: 'the size of a goat' WHICH GOAT. Goats vary so much in size, plus more petting zoo goats tend to be 'pygmy' species and so people whom haven't spent time around farm goats have a skewed perspective. I have seen adult goats the height of a hefty housecat or corgi up to a dairy cow. Which is a pretty big difference-- what is the platonic ideal of the goat, in terms of size??????
i cant find most of these animals info online? does anyone have links with there information?
Tylopods sounds like something babies shouldn't eat but do.
Wow I never knew oreodonts were tylopods, weird.
Helohyid future vid?
