...is not a dinosaur.

This blog is a result of an erroneous mistake; one day I referred to Dimetrodon as a mammal-like reptile in front of a vertebrate paleomammalogist. These animals are not at all members of Reptilia; they are Synapsids - four-legged, back-boned animals that span back 315 million years on a completely different evolutionary branch on the tree of life.

Since then, I've found Dimetrodon partying with members of Dinosauria across the pages of coloring books and frolicking in the aisles of toy stores, surrounded by lifeforms which evolved some 66 million years after those ancient mammalian relatives.

Submit your photos of any number of creatures - Synapsids, Pterosaurs, Ichthyosaurs - that have been tragically mislabeled. For funsies.

So I was play WoW and I was in Un’Goro Crater where it’s filled with dinosaurs and I encounter this creature named Diemetrador, obviosly resembling a Dimetrodon. I repeat, this place has almost only dinosaurs, and when you do this quest named “Roll the bones” to collect dinosaur bones, this creature drops a Dinosaur Bone!
So, Dimetrodon is being misidentificated in the gaming world as well.

are you going to tell me orcs aren’t real either? :(

that’s the last time I go to WoW for my natural history knowledge 

Here is a picture of the Quetzalcoatlus at the Texas Memorial Museum under the trending “dinosaurs” tag. Clearly a pterosaur, not a dinosaur.

But you must understand! I tagged that post with “dinosaurs” because it is actually a photoset including many extinct animals, including dinosaurs.

Strange Biology is a great tumblr. 

I’m a little more lenient with the pterosaur as a dinosaur confusion because they existed around the same times…. but still. A bat is not a bird no more than a pterosaur is a dinosaur! 


The Consumerist posted this article with scans of Christmas ads from 1989, including a toy “Definitely Dinosaurs” dimetrodon.

Jurassic mini golf including T-rex (which ruled during the Cretaceous, not the Jurassic period), and Allosaurus, which although IS from the Jurassic, shouldn’t be hanging out with Dimetrodon from the early Permian.

Seriously where is this? Because I would go to Jurassic mini-golf, scientific inaccuracies aside. 

A drawer full of tiny, tiny sadness at the local zoo. (They are cute, though!)

Found this on a cup that said “Dinosaurs of North America” at the Museum of the Rockies at Montana State University. The exhibits however are extremely accurate and make sure they establish the difference between things like Dimetrodon and dinosaurs. Plus, they have feathered dinosaurs!

You win some, you lose some. 

Dimetrodon even looks kinda dog-like here. 

My 9 year old future Paleontologist Sydney just brought this to our attention. Um, Dimetrodon what are you doing in this Animal Planet Dino Tube? You no live there.

Sydney is super unimpressed. 


I guess in this case we can just eat the mistake?

I wish all mistakes in life were as easy tasty to absolve.
