What the Hell is Turtle Evolution?

Turtles have been a mystery in evolution for a while. And new technology has helped to answer some of the unanswered questions about their evolution. Or at least it might have. Turtles are still being debated over. There's nothing like them today, so what does that, and the newest research say about their evolution.

Just think. You're a lizard just chilling on a rock somewhere. Enjoying some sun. Then you ask yourself, "Self? I'm tired of my ribs on the inside. These bugs know what's up. I bet I could push my ribs out of my back and give myself a hug with them." This the turtle was born.

Some scientists think the shell is hindering their evolution and maybe thats why octopuses are evolving so fast they dont even have skeletons or cartlidge

turtle skulls have openings at the upper rear of the skull called emarginations. It has been suggested that this is actually the upper fenestrae of diapsids and euryapsids. But the loss of some of the bones at the rear of the turtle skull causes it to open toward the back. Check out the skull of a snapping turtle to see just how big this opening can be.

@RaptorChatter 4 ай бұрын

Having looked for it, I am unsure which feature it is. In my herpetology class we discussed the lack of fenestra, but my professor was a snake researcher, so not a ton of time was spent on turtle anatomy. Do you have a source which discusses this idea? Because it sounds fascinating!

@ambystomaguy5825 4 ай бұрын

Turtles are endlessly fascinating; they're the only animal in evolutionary history to pull their shoulders and pelvis INTO their ribcage! A video on modern turtles would absolutely be worth watching.

You dont have to fully understand Turtles to know they are cool. I have a little Musk Turtle 🐢 in my living room aquarium. They actually behave similar to dogs. Walk around sniffing, digging holes, running around in circles when they see you. I like to think of them as the dogs of the Mesozoic.

There's no complication, genetic studies have conclusively shown turtles to be diapsid reptiles that are unrelated to parareptiles. I don't know why you keep retreading this with your videos

@RaptorChatter 4 ай бұрын

That is a very fair critique. I am attempting to be fair to both published ideas from the last few years, and the Chinlechelys paper was fairly recent. I agree. They are almost certainly closely related to archosaurs. My only concern is early parareptiles had the diapsid condition, and that far down the tree there's some debate still, so parareptiles, and archosaurs might (unlikely at this point) be sister groups. That is the only reason I hedge my bets in videos like this. It may take only one more fossil from the middle Permian, which more distinctly unites certain groups to resolve this. But that doesn't exist yet, so I wanted to be careful about nailing them down to a single position. That said, at the end I do reiterate that they are probably close to the archosaurs. In 5 years time it probably won't be an issue to say that, but for now there are still some discussions about it.

It of course make sense that turtles diverged from other reptiles shortly before a big extinction event. Because after the extinction event, all ecological niches were open for grabs, and thus the proto-turtles could successfully get on a completely different track.

Emerald tree boa. They are available in the pet trade, but buy from a breeder, because not taking more out of the wild is better, and also they can be defensively aggressive, so are usually more show snakes than handling snakes. There are green snakes which are more handlable if that's your interest.

@sampagano205 4 ай бұрын

I really hope we can nail down the relationshop of turtles to plesiosaurs, becuase the archosauroform identification seems very strong. They could be a key to understanding marine reptile evolution.

@RaptorChatter 4 ай бұрын

I agree, and wouldn't be surprised at all if it happens. The northern Tethys sea sediments in China have provided so many early marine reptiles I feel even a paleobiogeography study might hint at that.

many people dont even consider turtles (and crocodiles and dinosaurs) as reptiles. because they claim birds arent reptiles. which would mean dinosaurs arent reptiles and non of dinosaurs ancestors are reptiles. this + the fact that dinosaurs share a more common ancestor with crocodiles than either of them with lizards and snakes and turtles share a more recent common ancestor with that ancestor means that if birds arent reptils, neither are turtles and crocodiles (and the non avian dinosaurs)

I like the idea of turtles being super unique; so, the more ancient and removed their evolution from other reptiles, the better.

They're that even if they're related to archosaurs though. They'd have split off from birds and crocs before the Permian, which would make birds and crocs closer related to one another than they are to Turtles, which would be an entirely unique early branching group of archosauriforms.
