'Condylarths': Bizarre Early Ungulates

During the Early Paleocene, Placental mammals began to diversify explosively after the extinction of the Non-Avian dinosaurs. This included the ancestors of the hoofed ungulates, which often looked almost nothing like their familiar modern relatives. Indeed, many were very generalized animals, more closely resembling Carnivorans, Hyraxes and guinea pigs. Basal were omnivorous and sometimes even carnivorous, although adaptations for herbivory and cursorial behavior developed multiple times as well.

A compliment from one of your Patreons: This is an excellent production, with your characteristic combination of sophistication and clarity. I especially appreciate your willingness to acknowledge the uncertainties of this difficult subject and the often-fragmentary nature of the fossil material. Many, many thanks.

@@dr.polaris6423 I love that you so heavily focus on a lot of the more obscure Cenozoic mammal clades rather than just well known groups like dinosaurs, which already saturate a lot of Palaeo KZfaq. I hope you'll add some more marsupial groups, like Microbiotheria (the monito del monte and a long list of its extinct relatives), Peramelemorphia (bandicoots and bilbies), and Dasyuromorphia (thylacines, quolls, and numbats) to your queue of what is I'm sure many videos in the making.

​@dr.polaris6423 the theria/metatheria split would be great too. As well, a video on the several groups (e.g. sparassodonts, multituberculates) who apparently had marsupial-adjacent reproduction but are considered to have developed i independently of marsupials. IOW why did these several groups develop this method rather than going full placemtal

I absolutely love the Paleocene due to it being such a fascinating part of earth's history not explored much in paleo media. there are so many documentaries about the KPG extinction and yet very few about the world after. I would love to see a just a short of some of the habitats and creatures of that time period with a fundraiser at the end like Forgotten Bloodlines asking use if we want more.

I will say that the "Urbilaterian" is interesting. It's the common ancestor of insects and humans, and it's unknown how complex it was. It's also mysterious how long ago it lived, but it likely lived during the Ediacaran. I might try and make a video on it.

For me, hands down, the Ungulates are among the strangest group of land animals ever to evolve apart from basal tetanuran theropods (like Chilesaurus). Both groups of these animals represent a fork point in the evolution of their respective species. Very strange, very weird.

I'd like to see a video of fossils found closest to K-Pg extinction, fossils on both sides of it as I haven't ever seen something like that. More about what generally was before and after. But I do not know if it would be easy to find information about fossils located very close to it and probably because of it, the generalized stuff and talk about rock layers.

Thank you for going where no paleotuber usually goes. The time right after the Kpg extinction is a paleo wild west. Most mainstream paleo covethe dinos, the extinction and skip straight to the Pleistocene. It's fascinating to think that for half of the "Age of Mammals", it was a "dinosaur" world; as hot if not hotter than the Cretaceous and Mesozoic at large. All mammal origins are from these other worldly jungles.

Thank you for another excellent, educational video. It will be interesting to see how the classification and reordering of condylarths looks in ten or so years, and further. I wonder if it's viable to do a series that looks at the Earth: 1 year 10 years 100 years 1,000 years 10,000 years 100,000 years 1,000,000 years 10,000,000 years after the asteroid impact 66 million years ago? To compare and contrast fauna and flora, land and sea.

Very interesting video: the Paleocene is a fascinating and mysterious but mostly overlooked era, when vertebrate evolution practically restarted from few species survived. I think it would be interesting a video about Ancalagon Saurognathus the earliest known large carnivorous mammal (bear sized) that lived from 63 to 60 million years ago in North America, since very few online information about this animal is available.

I agree with the last three, but the first three already heavily saturate palaeomedia. For now, I'd prefer our favourite polar bear with a PhD to cover less well known fossil groups like procyonids, skunks, koalas, bandicoots, monotremes, and heterodontosaurids.

"Triacus" -- I could swear the sword was used in Star Trek TOS as a planet and species name. -- Very interesting for it to be a civet-like or raccoon-like ungulate omnivore / carnivore. -- Prehistoric mammals are so odd, such a mix of almost-like modern animals, and so easy to imagine prehistoric Earth as being so similar, so different, like an alternate reality. The curious thing is how it could have gone in so many directions, so that we could have had a very different present-day world of animals, including a different kind of hominid, similar to, but not quite like us.
