I was commissioned once again by friend Greg Noneman to illustrate a fight inspired by Primitive War, by Ethan Pettus, between a father tyrannosaurus rex and a modern day grizzly bear- obviously, the bear isn't winning...

*Note: This isn't supposed to be accurate, this was just a fun concept based off of what Greg wanted design wise. I'm aware tyrannosaurus rex probably didn't look like this. 

*Note: No bears were harmed in making of this illustration and I have nothing but love for our ursidae friends.

For those of you who don't know, my two anatomy books "An Atlas of Dinosaur Anatomy" and "An Atlas of Prehistoric Animal Anatomy" are up for sale! If you like my studies like this one then you will love my books! Both come with many animals and several that will ONLY be found in my books! There's also a special Evolution of Baleen Whales in my Prehistoric Animal Anatomy book, you will not find this study anywhere else! Feel free to ask me questions. I will be selling them at Amazon and Barns and Noble soon, I'm going through the whole process and I will post links as soon as they're approved! You can buy them now from Lulu at these links:

thank you for making the tyrannosaurus to some degree, historically accurate 
(the feathers)

actually if t.rewx had feathers, it's likely they were small and more akin to hair of elephants.

It could be a scene from “Footprints of Thunder”, by James F. David, an awesome, too overlooked epic.
imagine “Jurassic Park” if it had been coauthored by Rod Serling.

When Ethan Pettus the author of the novel began writting it in the waning years of the 2010s, he went with what was the then accurate model of T. Rex being feathered and as such it's now stuck, and feathers really work for this book series both from design asethetic and from in-story lore. I imagine if he had wrote it nowadays he would've went with scaly. Much research goes into the writing of the book and I've even helped in that regard by speaking with tyrannosaur paleontologists Dr. Thomas Holtz and Dr. Thomas Carr. Anyone in the comments section that's curious to learn more of the backstory behind Primitive War along with other behind the scenes secrets, I have two interviews with the author on my YouTue channel, and if you search for Primitive War followed by Ethan Pettus in the search bar, you'll quickly find my interviews. I also will include links to the relevant PW pages to follow on Facebook and Instagram which includes all the official concept art, more community creations like this, and other exciting content.

The piece overall came out fantastic, with the Father T. Rex really looking like a force of destruction in this foreshadowing of events to come from later novels as the dinosaurs continue on their migration from outside of that Vietnamese valley they first appeared in. The next commission Rushelle does will be 100% legit Primitive War content as she partakes in "The Father's Hunt" series, a series of illustrations depicting the Father T. Rex on several of his Asiatic Elephant hunts in varying sections of the Valley plus showing different stages of the hunt. Also partaking in the series will be paleoartists Emily Stepp and Jeremias Reyes whom is also the new official concept artist for Primitive War II: Animas Infernal which will likely be out sometime within spring/summer of 2020.
