Description
An image from a powerpoint I'm making, depicting what the relations of some animals commonly called "dinosaurs" actually are compared to actual dinosaurs. Red are the non-archosaurs, yellow are non-dinosaurian archosaurs, and green are the dinosaurs.That rauisuchian looks wonky, I know.

i feel like dimetrodon shoud be a different colour than the marine reptiles, because at least the marine reptiles are at least true reptiles ratehr than mammal relatives
👍: 0 ⏩: 0
I almost feel as if dimetrodon should be another color (perhaps blue) considering it is the only reptile that was more on the evolutionary side towards mammals, which is interesting in its own right. But it would be for the most part irrelevant to the main point.

I guess that the bird is teasing the rest since it's Class is the only one in the picture with extant members...

in the thumbnail i thought that rauisuchian was like some iguanodontid or close affiliates (due to its tall looking trunk region), but just as fast as that thought clicked me, i immediately saw it was colored yellow, so je-yup!)

It isn't that hard to stomach, when you really get down to it, there's nothing dinosaurian about Dimetrodon, the necessary omissions you have to make to call it a dinosaur are enough to call dinosaur any random lizard or salamander, and maybe even a mouse could fit the bill.

Lol the pteranodon looks like it does not give a crap

The Pteranodon stands there, contempt with it's placement as a Sisterclade to the Dinosaurs.

This is funny! I really hate it when people mix up creatures such as these with dinosaurs.

Should've added a wooly mammoth. Those get called dinosaurs too.

The walking with monsters BBC program had to stress that they were not in the time of the dinosaurs when they went to the part about the early Permian. It is sad that a documentary has to do that.

for me, you have no idea how sad that is to me! yeesh even i knew that as early as alongside another fact that cats are not 4 legged owls!

Thinking plesiosaurs, pterosaurs, pliosaurs and permian reptiles are dinosaurs is very common. However I've heard of much worse cases, some people think all prehistoric creatures are dinosaurs. In Primeval, in some episodes, creatures like Hyaenodon are called dinos.

You never watched the show, it seems.
They always say they're dealing with dinosaurs.
👍: 0 ⏩: 1
They said that because that is the best known example of extinct animals. They make it quite clear that they are dealing with other things.
👍: 0 ⏩: 1
And why say both? It's contradictory to call something a dinosaur and then say it's not. I still assume they don't really know what they're talking about.
👍: 0 ⏩: 1
That may be contradictory but they always identified the creatures as whatever they were.

I haven't watched the show since season 5, but I don't think they noted that the Pteranodon, Mosasaur, Hyaenodon, Anurognathus, Titanoboa, Diictodon, Scutosaurus and Gorgonopsid, among a few others, weren't dinosaurs.

Yup, the cast calls everything old a dinosaur!

Awww, I remember when I did something like this in my high-school biology class, good times . I had to rely on the first part of WWD, then fill in the blanks by simply talking abut it. I liked it so much I did it again, even though I didn't have biology after my 2nd year, that year I focused on feather evolution.
So I support your powerpoint

Good diagram. If you wanted to, you could've made Dimetrodon another colour to signify it being a non sauropsid.

A useful image. It's funny how all the other creatures look so upset at being excluded. But maybe you should add some other kinds of dinosaurs too, to make it easier to understand (sauropods/ornithischians).

I left out the other groups of dinosaurs just to keep it relatively simple, just like how I kept out pretty much anything that could be called a dinosaur. Plus I'm going to be talking about image while it's presented.
