The Origin of Mammals group is for artists of prehistoric and extinct mammals as well es their ancestors, the Synapsids.

This group shall show the best and the scientific most accurate artworks of our extinct next relatives.
Feel free to join, everybody is welcome. But submissions will be hardly reviewed, so don't feel bad if your work hasn't fulfilled the regulations.

If there is any problem with joining or submitting, please send me a note. Administrating groups in deviantArt is a very confusing work.

Please read the
Rules & Regulations
Please read the text below carefully before you start submitting. If there are any questions feel free to send a note with the subject.


There are no restrictions for joining. Everybody who likes to join can do that. Joining requests are automatically approved. You are not committed to submit any artwork if you join, it's completely free.


If you won't be member anymore you are free to leave at any time you want. But we would enjoy to keep featuring your artwork you already submitted.


As a member you're allowed to submit artwork from your gallery. The group moderators may suggest artwork from none-members also. If you want to submit be sure that your work hit the level which is required. There is no restrictions for submitting-quantity at the moment. For more information about the requirement read further.
What we will accept:
This group has the intention to show the best and most accurate artwork of Synapsids (mammal-like reptiles) and prehistoric or mammals which went extinct in modern times. Your work shall show obvious use of references like skeletons or scientific sheets. Skeletal reconstructions have to be very accurate, but don't have to be complete. Life-reconstructions offer some space for imagination and speculation. But be sure that your imagination and speculation is comprehensible and scientific plausible.
Your artwork can be black and white (shaded) or colored. You must not use backgrounds or benchmarks. Traditional and digital media is accepted. And please come up with your own ideas, don't use the style of TV shows (like BBC or Primeval) or other artists.
What we won't accept:
We only accept artwork of other animals than the mentioned if they are a part of the whole image or used for comparison and the main topic is a Mammal or a Synapsid. Don't submit scraps or WIPs, we also don't accept photos. You have to show the animal with a neutral background or a natural environment with natural behaviour, so don't put the Dimetrodon for example under a carribean coconut-palm or vest him with unlikely behaviour or anatomy.

The rules can be edited at any time by the Founder and changes are retroactive.

Does this qualify for the group?

I used these as references:………

(I had to reference the Moschops skeleton because there are no side-view references right now for Keratocephalus)
Is this group material?

The reference is from here:…

Actually no, there are some aspects which would prevent this from accepting:

1. It's obvious that you used photos (the eye of Elephas maximus) and/or brushes to obtain the texture. I tend to decline photomanipulations, unless they are of an excellent quality. And even then I'm precarious because of possible copyright issues.
Despite that I think it would be unfair against other artists who don't use such ways to 'enchant' their works digitally.
Same goes for 3D-art if the models aren't own work.
The thing here is also, that it isn't well executed. Shading an texture-pathway don't work that well. Also it would have been a better decision to use the skin of Hippopotamus or species with similar lifestyle and size as reference.

2. The tongue describes a sinuous wave. This is likely impossible for such an animal. In most Vertebrates the body of the tongue lays flat in the mouth and then curls at the end. Try to search for pictures as references, here I have some for you: Wolf yawning, Lizards yawning and oped-mouthed Birds.

3. The way you depicted it, it looks like the head doesn't even belong to the rest of the animal, also the cranium is very distinct from the mandibles.

4. The whole body-shape is wrong for a Dinocephalian. Use the skeletons of related Genera to reconstruct such a fragmentary species in a believable way. Also no Dinocephalian or non-mammal Therapsid had such columnar legs, they were spread-out (karkemish' reconstruction is quite a bad reference point for that).

If there are still questions, feel free to ask.
How about now? it's been changed.

I referenced the cranium from Haughton, 1929, "on some new therapsid genera", the palaeocritti site on teeth and mandible, and used Estemmenosuchus as the guide for the postcranials
Okay, just needed to know.

Hi, I'm trying to recruit some creature artists for a group project ([link]). If anyone is interested, let me know and I'll send you a group invite :)
