my understanding was that crocodiles could be differentiated from alligators by the feature that the latter will see you later whereas the former will see you in a while
@@novedad4468here usually used together, one in response to the other Someone says "see you later, alligator" and the other says "in a while, crocodile" Rhyming puns!
I love this so much. You don't cut out mistakes, you include good and enough information, you make jokes, and DON'T USE A CRAPPY AI VOICE, thank you, subscribed.
id love to see a video exploring the groups of birds, kinda like your mammal one but instead of being mammals its birds, either way i love your content please do more!
The best pronunciation of araripesuchus I’ve ever heard from (what I presume to be) a native English speaker. The Rs in it are supposed to have a vibrato sound that doesn’t exist in English and is made by slightly vibrating the tongue against the roof of the mouth
who else what's a remake of the documentary When Crocs ate Dinosaurs that takes place from the Triassic to Pleistocene and covers all the fantastic crocodylomorphs throughout prehistory.
I'm so glad that you put Iharkutosuchus in this video, I would not expect that you even know this specie. But to tell a fun fact, (ok, I just want to seem cool) the paleontologyst who found and named that croc teached me at university🤗🤗
Why is the archosaur branch called Pseudosuchia if it includes the living crocodiles? That name would fit with whatever convergently evolved the appearance and niche of crocodiles.
Pseudosuchia as originally defined only included non-crocodilians. Unfortunately phylogenetic analyses resolved crocodiles as deeply nested within this cluster of archosaurs and the name Pseudosuchia has priority over alternative names for this clade. Kind of the same situation when birds were discovered to be deeply nested within Dinosauria = birds are now terrible lizards, while crocodiles are now false-crocodiles.
Amazing how things so primitive are still here. Although I wonder how modern species are able to get by since they require so much sunning time and many have to drag prey underwater to drown them. Obviously they don't have many predators but still seems inefficient to me
"I think you left out the Sebecids. They're the third clade of Crocodilians that made it through the K-Pg line and they were fully terrestrial" - no, not left out. They are not a clade of crocodilians, nor are they within Crocodilia at all
Why don’t you get to think of a suggestion and creating of another RU-vid Videos that’s all about The Evolution Of The Hyenas on the next Animal Origins coming up next?!⭐️⭐️⭐️⭐️⭐️👍👍👍👍👍
Corrections: Pseudosuchia is an invalid clade. By definition archosaurs are crocs + dinos (including birds). These two are sister clades with bipedal ancestors, like Scleromochlus, Pseudhesperosuchus and Junggarsuchus. (Where are they?) So that shuts out all the other traditional pseudosuchians using the last common ancestor method. Poposauria is the outgroup to the Archosauria. Turfanosuchus is the last common ancestor. Other archosauriformes (Euparkeridade, Erythrosuchia, Rauisuchia, Aetosauria, etc) are outgroups to these three. Litargosuchus and Terrestrisuchus were obligate bipeds with really long legs, but your illustrations show them to be rather short-legged quadrupeds. Kayentasuchus is known from a skull, and it is closely related to Litargosuchus. So toss out your current illustration. Hemiprotosuchus is basal to aetosaurs, so not related to croc relatives.
Crocodiles are one of the most infamous reptiles and they are closely related to the dinosaurs and it's been 65 million years since they first exist in the planet.
Crocodilians are reptiles that constitute the order Crocodilia, they are known for their elongated snouts, semi-aquatic lifestyle, and very sharp teeth used for catching prey, there are four extant families of crocodilians: Alligatoridae (Alligators), Caimanidae (Caimans), Crocodylidae (Crocodiles), and Gavialidae (Gharials), while both crocodiles (family Crocodylidae) and gharials (family Gavialidae) are the only extant families of the superfamilies Crocodyloidea and Gavialoidea respectively, both alligators (family Alligatoridae) and caimans (family Caimanidae) belong to the superfamily Alligatoroidea, where alligators and caimans are the crown families of alligatoroids.
Beware of a commenter below called Indy Reno posting nonsense taxonomy and other flawed info. He does this all the time and stubbornly ignores criticism.
@cholachanthyes9191, caimans are in the superfamily Alligatoroidea, but not the family Alligatoridae, just like pygmy and dwarf sperm whales are in the superfamily Physeteroidea but not the family Physeteridae, caimans constitute the family Caimanidae as one of the two crown families of alligatoroids, much like how the pygmy sperm whale and dwarf sperm whale are the only two extant members of the family Kogiidae, which is one of the two crown families of physeteroids.
@cholachanthyes9191, actually, there are officially now four extant families of crocodilians based solely on name: Alligatoridae (Alligators), Caimanidae (Caimans), Crocodylidae (Crocodiles), and Gavialidae (Gharials), the former two constitute the superfamily Alligatoroidea, while the latter two are the only extant families of the superfamilies Crocodyloidea and Gavialoidea respectively.
mate.. 'inside' and 'in' are distinct terms.. inside requires an objective place with a defined interior. you cant be inside water, it's just in. likewise it's in the clade, not inside.. like you could say in or inside a cell, but it's just in cellular chemistry, or.. inside/in the house, but it's always just in the town, you can't be inside a town even if it's it's got medieval walls around it... because then you're in the town *within the walls,(aye , within, not in _or_ inside them. )
