Diabloceratops eatoni

A centrosaurine ceratopsian from the Wahweap Formation of Utah, this dinosaur was first described in 2010 by James Kirkland and Donald DeBlieux. It lived during the Late Cretaceous (Campanian Age) about 79 million years ago.

Considering that the modern Rocky Mountains were being formed at the time, it seems possible that an unfortunate Diabloceratops might have encountered volcanoes. Volcanic lightning is a real natural phenomenon, and if you haven’t seen photos I highly recommend an image search – it’s amazing.

After the last few calm, quiet scenes I’ve painted, I figured a different tone might be fun, though the results may be straying dangerously close to something one might encounter on the side of a van… in the 1980’s…

Time for a March Dino Madness Smear Campaign Post

Hey hey friends

So I know that y’all are filling out that Ornithischia survey for @a-dinosaur-a-day‘s March Madness thing. And I’m learning a disappointing thing.

My two favorite Centrosaurines, Nasutoceratops and Diabloceratops, are losing to Pachyrhinosaurus. Which is unacceptable. (the other unacceptable thing being that you have disappointed Jingshangosaurus by not letting them compete this year)

So, I am here to try and convince you to do the following: open up the Ornithischia survey, go down to Centrosaurines…

And cast your vote (or revote!) for Diabloceratops instead (the genus has a more likely chance of winning than Nasutoceratops.

And, if Diabloceratops gets nominated, I’ll draw one. (The one above I drew on the screencap of another Diabloceratops drawing was with a mousepad, I can draw much better than that).

So, now you’re wondering what the smear campaign is? A vote for Pachyrhinosaurus is a vote for this:

(yeah, remember this? you better, it’s Talking With Dinosaurs)

Now, go vote for the actually great Centrosaurine with a chance. @bruh-i-nevre-seen-a-cooler-dino @palaeofail @palaeontology-official

TGI Fossil Friday!

With a body reaching about 20 feet in length, Centrosaurus, which belongs to a group of horned dinosaurs called centrosaurines, was smaller than its more famous cousin Triceratops, which belonged to the other major group of horned dinosaurs called chasmosaurines.

This specimen was uncovered by famed fossil-hunter Barnum Brown in 1914. He considered it to be the most complete specimen he had ever found, “in all details from the tip of the tail to the end of the nose.” Centrosaurus lived in the Late Cretaceous, about 75 million years ago. Brown and his crew discovered the skeleton in the spectacular badlands along the Red Deer River in Canada.

This is highly relevant to my interests.

Hi everyone!

Jack here, one of the artists doing illustrations here at ADAD. Just making this post to remind you all that we do have a Patreon at patreon.com/officialadinosauraday. Now, some of you may be thinking “but you’re just a bunch of nerds on the internet making short Dinosaur factfiles, it can’t be that hard. Stop being greedy,” but, while we are indeed a bunch of nerds on the internet, the effort and time we put into each entry can be quite surprising. I shan’t speak for Meig or Ryuu, other than that I know each will frequently spend over two hours researching and working on their component, be it art or writing, for each post, but I will share with you a little bit of my own process to try and convey the hard work we do every day.

First of all, I need to check the schedule.

 As you can see, or maybe can’t, as the image is small and tumblr sucks at photos, I’m up today (the 21st of January, 2017) drawing the centrosaurine dinosaur Achelousaurus. My first step is to gather reference images and information. I won’t share that part as A) there are a lot of reference images, and B) some of them exist in books and I can’t share them for copyright purposes.

Based on these references, I have sketched the skeleton, posed it how I want to, and sketched major muscle groups on top as well as a vague soft tissue body outline. All of this is messy and done in blue, but it demonstrates the time and effort put into making sure each illustration is done in accord with the prevalent fossil data.

Now it’s time to sketch the lineart layer. I don’t always use a separate lineart layer, instead sometimes opting for a more painterly approach, but I find this saves time and allows me to make sure the outline and features of the animal are visible and clear. There is an element of speculation in the exact soft tissue features exhibited in each dinosaur, though no feature is put in if it is known to be incorrect, and often things (like large tubercules spread over the back of the animal) are seen in other, closely related animals. You can see how it adheres roughly to the form sketch (in red), with skin folds around joints and the form of some muscles showing through, but not every single detail makes it through the layers of fat and skin and scale.

Now onto colouring. This part can take quite a while, and if done badly it can make the piece look garish or just straight-up not like an animal. Unless pigments are preserved, this part is down to the imagination.

And that’s it done! This piece, which you can see in today’s (21/01/17) post, took roughly two hours and twenty minutes to complete, but they can take up to as much as four hours. I do one of these every other day, as does Ryuu. Meig writes a minimum of one article every day. As you can probably tell, this is a lot of effort, and we’re dedicated to providing the best content we can, available to everyone, for free. However, if you are in a position to do so, and you do enjoy the work we do, please consider supporting us over on Patreon at patreon.com/officialadinosauraday. It means the world to us, and the more support we get the easier it becomes for us to produce this content and increase the quality and quantity of writing and artwork.

Many thanks to all of you for your support. We’re truly fortunate to have such a wonderful community here, and we hope to continue providing the best dinosaur-related content we can.

Cheers for reading!
