As the time to talk #SurvivingEarth nears, I wanted to say that I’m extremely proud to have been part of the amazing team who worked on it

I was commissioned by Tim Haines (producer of Walking with Dinosaurs) and his team, to create the concept art for MANY animals for this project!

Three sketches of Styracosaurus, mostly focusing on its head

For today’s sketch let me present you with Styracosaurus

Styracosaurus lived during the Late Cretaceous in North America. The arrangement of very long, 4-6 spikes protruding from its relatively short frill and long nasal horn is characteristic of this species

Today let me sketch one of the largest theropod #dinosaurs, the enormous Giganotosaurus carolinii

Giganotosurus lived during the latest part of the Cretaceous in South America. It had a long, tall and narrow skull with prominent crests. These crests were rugose and had numerous ridges

5 sketches of Deinocheirus in different positions. Some of the sketches are details of its head and neck

Let’s sketch the magnificent beast that is Deinocheirus!

Deinocheirus mirificus was a huge ornithomimosaur that lived during the Late Cretaceous in Asia. This herbivorous dinosaur had huge arms with large claws that were probably primarily used for digging or gathering plants

Deinocheirus is one of my favorite dinosaurs. We discovered just the arms first (the name means β€œterrible hand”), and spent ~50 years imagining this giant terrifying predator, then when we finally found a more complete fossil it turns out to be this derpy-looking dude.

One good thing about cold weather is that it makes it much easier to observe mammals during the day.

Like this beautiful Coyote (Canis latrans) and Virginia Opossum (Didelphis virginiana) I found
