Lizards are incredibly widespread and diverse but it took them a long time to get to where they are now. Because they used to face some pretty stiff competition from a group of lizard look-alikes.
Thanks to these wonderful paleoartists for their excellent lizard/fake lizard illustrations!

When the impostor lizards are sus
GohanLSSJ2 پیش 22 ساعت
If we wanna get really loose with the term "lizard" then the basal amniotes, their reptiliomorph ancestors and even the earliest sauropsids and synapsid pelycosaurs were basically lizards, too.

I don’t understand the difference between lizard and dino? Why the separate category?
Rexyjp123 پیش 17 روز
I think it is cause dinosaurs have more hollow bones like birds
Grain Assault
Grain Assault پیش ماه
It's hard to explain for someone who doesn't know alot about taxonomy, but dinosaurs are just a separate group from lizards. Also, dinosaurs tended to walk with their legs directly below them and mostly with their back legs (many types were bipedal including today's birds) while lizards usually have their legs out to the side a bit and use all four equally. Lizards and dinosaurs are both reptiles. Birds are a type of dinosaur, and snakes are a type of lizard. Crocodiles are more closely related to dinosaurs than lizards.

You know what one of my favorite things about Sci Show and PBS Eons and the rest of your projects is? You guys are all huge dorks. And I mean that in the best way, as a huge dork myself. You guys love this stuff, you love learning about it and you love teaching it, and you also can't keep a straight face when you share those awful jokes and puns at the end. I just love your "oh goddammit" faces. XD

well damn. didn't know i lived in the last bastion of the sphenodons. I guess New Zealand was the last bastion for many different species. i mean if you consider birds to be dinosaurs then i guess New Zealand is the only country were dinosaurs continued to rule after the cretaceous

Tuatara should be introduced in a self sustainable reproducting numbers to different habitats all around the world - in which they can climatly and resoursefully survive and thrive - in order to save Sphinodontians out for the future natural historical ages of our world.

Imagine how wrong some of our ideas must be about these animals. I mean, just take a hippo's skeleton. If you looked at it you'd imagine some monster from Star Wars, when in reality it's just a chonky water horse. Just think about how wrong a lot of our reconstructions might be without the actual soft tissue giving us a solid clue. Perhaps the Triassic creatures weren't half as weird.

What exactly stops us from incorporating Sphenodontians into the definition of a lizard? The floating jaw and single hole aren't ususally what people look for when identifying a lizard so why stick to those as criteria when you've found very lizardy ancestors of lizards that don't have those features?
