Lalieudorhynchus: Permian Hippo-like Protomammal

[@dinohall2595]

The narrator's ability to consistently pronounce "Lalieudorhynchus" correctly is something I can only dream of achieving in life.

People usually say the Triassic animals were pretty weird, which is kinda true. However the Permian seems to have its share of animals with unusual head or bodyplans. There is even a clade of Permian synapsids called "terrible heads", difficult to get weirder than that.

[@jameskazd9951]

There is a lot of weird stuff at every period in time really, even today. just look at the platypus

[@altanativeftw2625]

The Triassic was very weird because it was sandwiched in between two extremely severe mass extinction events, making much of its biota unlike anything before or after. But the same can be said for the Permian, which saw two mass extinctions (end-Guadalupian and end-Permian) and a less severe extinction event (Olson’s extinction) all within close proximity to each other, creating the same “weirdosity” effect. Furthermore, at the beginning of the Permian, the world was at the peak of the Late Palaeozoic Ice Age and resembled the Last Glacial Maximum, but at its end was an extremely arid supergreenhouse more severe than even the Turonian and Early Eocene supergreenhouses. Additionally, during the beginning of the Permian, the Carboniferous-Earliest Permian Biodiversification Event was still ongoing in the seas. It truly was an incredibly dynamic and interesting period.

[@floflo1645]

@@altanativeftw2625 thanks for the explanation

[@UniDocs_Mahapushpa_Cyavana]

Permian animals are only weird by today's 🏙 standards. The Triassic animals were weird in general, because they had terribly adapted forms that only stuck around because of no competition or competent predators for them.

Great work as usual! Nice to learn more about both caseids and anteosaurs in the same video. Didn't know anteosaurs were, potentially, water-savvy creatures.

[@chimerasuchus]

The study of Permian faunal isotopes mentioned in the video found Anteosaurus spent a notable amount of time in the water, likely because herbivorous dinocephalians spent an even greater amount of time there. Even though they were mostly terrestrial, anteosaurs were actually once perceived as crocodile analogues.

[@jamesdavison6290]

First of all -- I love this channel! Tor decades into the future this makes detailed knowledge accessible for folks that don't want to take a graduate course! Now for the bad news -- my own speculation! A huge animal like that could never sink. Its gut would be full of gas, and it was a floating island. The only alternative was if it ate huge quantities of rocks or sand to weigh it down, which seems unlikely, although some paleontological context might be helpful here. Those big forelimbs suggest to me it was digging through mangrove-like environments eating woody roots and letting its huge gut do the work of digestion, and maybe floating around the rest of the time. Maybe crawling on land to lay eggs at times. IMHO.

[@bencake28]

The answer to the question: how they lived? is evident through anatomy and environment. Like today's iguanas of Galapagos Islands. The water is great for escaping the heat and offers more plant food than land. For me the case is clear. This lifeform lived on coasts, rivers and islands and went into the water to eat. 🤓🤷🏽 Thanks for the amazing Content! 🦖

Based on reading Wikipedia articles, it seemed that many Permian animals kinda wanted to be the hippos of its time.

[@TheFoshaMan]

As far as I remember the Varanopids are still being considered Synapsids

[@chir0pter]

Another awesome video! Chimerasuchus' production and this narrator go well together. I wonder if Lalieudorhynchus and other derived caseids could be better compared to beavers. Stocky animals with short necks that escape into water to avoid predators and sleep but forage on land. Perhaps the answer to the caseids odd anatomy could be found in the paleobotany of the time. Were they a perfect height to graze on groundcover cycads trunk crowns? Was there a large stalked herb like a large horsetail that, like a beaver processing a tree trunk, benefits a herbivore designed to sit in one place for an extended period? Probably should widen the search to caseid associated paleofloras in general and not just this one species

[@hangebza6625]

I say there are 4 rules in Evolution: - crab is best - Your ancestors were noodles, your descendants will be noodles - everything will try to fly, no matter how many limbs they have - since vertrebrates took over the land, there will always be hippos

[@1998topornik]

Very cute protomammal. It is shame we will never see how this critter behaved in the wild.

[@pittbullking87]

Miocene Rhino Teleoceras had a broad, hippo like body and was thought to be aquatic. More recent studies show it was likely a land animal however.

[@secondbeamship]

I still buy the idea that sauropods were so heavy that they had to live in water as semiaquatic grazers.

[@petrairene]

Turtles and tortuses also have tiny heads for their body size. Convergent evolution? The plump body is an advantage if they forage under water because a larger body mass means they cool down more slowly so can stay active under water for longer until they have to return to land to bask. I would compare it more to a crocodile lifestyle, alternating between periods of basking on the beach and getting food under water.

[@laelaps5246]

I was thinking the same about the turtle-like shape, but turtles usually have very long necks (even if they are retractable and may seem short when not extended)

[@misanthrope22]

Why does the depiction of lalieudorhynchus remind me of Tommy Boy? Kid in Bank: Hey, Mom! It's the guy who robbed the bank. Tommy: I didn't rob any bank. Kid in Bank: Oh, yeah, right. Like it was some other real fat guy with a tiny head. Tommy: I got a tiny head?

[@GhoulsMagnets]

I was thinking, how possible is it that they were more manatee like? Except floating on the surface, rather than deeper into the water, because of their ectothermy. In this concept, they would feed on algae and plant matter floating on the surface. If they even leaned towards a detritivorous lifestyle, that could explain the purpose behind ridiculously large guts

[@blueturtle06]

I had a thought, just like ducks are classified into dabblers and divers, maybe they fed more like dabblers at the top of the water, if they were semi aquatic. Maybe the specialized much like a koala on a specific species of water plant much like water Lillie's or duck weed, just a thought.

[@lerneanlion]

WIll they still be scary if they behaved aggressively like hippos? If so, will it benough enough to scare the predators away?

[@chimerasuchus]

Even if it had the temperament of hippos, Lalieudorhynchus would have been slower, less active, and it had a less impressive arsenal. Although it would be far from harmless, the idea kind of reminds me of the Toaster from Fallout New Vegas.

What if it was a shore/bank feeder that just floated at the surface, with just it's back and head showing above the water, to safely feed along the shore? idk...

[@PurpleRhymesWithOrange]

What is they were floaters? What if they slept by floating on the water, thus eliminating the problem of needing to surface to breath? They could have floated alone expending very minimal effort eating floating plants (such as water lilies) and plants growing in the shallows.

[@ecurewitz]

Maybe they migrated or hibernate, which would explain why a semi aquatic animal would live in a monsoonal wet and dry climate

So in Permian age we already had “alpha versions” of saber-toothed cats, marmots, lemurs and, apparently, hippos. It would be fun if someone discovered flying or fully aquatic synapsids similar to modern bats and whales.

[@justdavedoindavestuff3479]

When I first read the title, I thought it said proto hippo. I don't know how that happened. Now I want to know where hippos came from.

[@catherinehubbard1167]

I’m envisioning these animals as FLOATING eating machines, not needing a long neck because of focussing on consuming massive amounts of vegetation on the water SURFACE. This is unlike hippos, which were bottom-walkers and ate land plants.

[@RobertGotschall]

The common chuckwalla ( Sauromalus ater) of the American South West also has a very large body with small head, but is only about 16 inches long. It is slow moving and a vegetarian. The large body may be a selective advantage for digesting desert plants. If the chuckwalla is a product of convergent evolution, I wouldn’t necessarily expect Lalieudorhynchus to be aquatic.

Correction: Caseids are derived from Milleretta and had a synapsid-type temporal opening by convergence. You're not to blame for this mistake. This is a traditional myth that won't go away for several decades based on how long it took for paleontologists to realize birds ARE dinosaurs. Related taxa include Feeserpeton, Australothyris, Aclieistorhinus and Eunotosaurus. None of these are related to synapsids. You can test this hypothesis of interrelationships by including pertinent taxa. Google: the-case-for-cutting-caseasauria-out-of-the-synapsida/ for a 2011 blogpost on this topic.
