Xenokeryx was one of the strangest mammals of the Miocene. Almost a chimera of different looks from many different animals. But what was it, how did it live, and why did it and its relatives become so successful?

Ruminant evolution is so interesting. Its also wild to think about how dinosaurs filled similar niches without these four chambered stomachs. It makes me wonder if Sauropods developed other strategies we dont have fossil evidence for like specialized gut flora or even fermentation in their guts.

[@juliusfucik4011]

Rocks

[@SoulDelSol]

They had multiple chambered stomachs too probably.

[@scottmccrea1873]

Well, we don't really know what the sauropod or hardosaurs internal anatomy was for obvious reasons. Given the simple dentition of sauropods - often just simple teeth designed to strip off leaves - they were probably fermenters of some sort. Whereas animals like iguanadontids had huge batteries of grinding teeth that did much to breakdown the cellulose before it got to their stomachs. Be interesting to here an expert (Darren Naish where are you???) on this.

The dutch name for ruminant is very apt. Here it's called a "herkauwer" or, a direct translation: "re-chewer"

[@LuisAldamiz]

Ruminant is from Latin. At least in Spanish "rumiar" (ruminate) is exactly "chewing the cud". I believe "ruminate" originally also meant that in English, although now it's rather "think on something for long".

Ahahaha. I knew they'd be related to okapi and giraffes! This was a cool video, I'd never heard of this taxon of animals before

[@scottmccrea1873]

Which means they're related to the pronghorn, which is the closest living relative to the giraffe/okapi

A long video about the evolution, fossil record and history of Canidae and Caninae (the dog family) going from the present and all the back to the Paleocene and Cretaceous would be fascinating. I did read that the fossil record for mammals gets spotty in the Paleocene. The mystery is interesting. Another video about mammals during the Paleocene and proto-mammals from the Permian to the Cretaceous would be interesting. I did read somewhere that the earliest evidence for fur is in the late Permian. A video about the earliest evidence of fur would be interesting. I do wonder about the history of milk production in proto-mammals but that's likely to be tricky to know from fossils alone. Dinosaurs and reptiles get a large amount of attention regarding the Cretaceous and earlier. The evolution and fossil record of mammals and mammal ancestors is fascinating though. I'm interested in paleontology and I'm a dog lover. Dogs, wolves, coyotes and red foxes are my favorites. :)

how can you tell the shape/amount of stomachs from a fossil?

[@sciencenerd7639]

great video, thanks

[@AllegedlyLoge]

Think there's a little more audio coming from the lef than the right which is irritating my ear quite badly, might just be my headset, not sure. Good video though! Keep it up.

[@RobertGotschall]

Thank you. I need a quick reference for the next time I'm told an early hominem, or any primate, could eat grass like a cow.

[@robrice7246]

Wasn't Miocene Europe a bit more like the Paleo & Eocene around this time (since Apes were present), and why was that (whether it might be from the Himalayas redirecting heat and moisture or not)?

[@michiganscythian2445]

The planet cooled significantly during the Miocene and the expanding grasslands really jump-started equid evolution and began favoring swift running grazers over browsers

~ 2:23 I've been taught that you pronounce abomasum like abo -ma sum [ˌa-bō-ˈmā-səm ]. This also could be true for omasum /oˈmaː.sum/ ? I remember this from my veterinary science courses in the USA so it could be different in the rest of the world.
