Very quick rough sketch
of the newly described spiky Hadrosauroid dinosaur Haolong dongi
I had to at least rough sketch this beauty!

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

Let’s sketch one of the giants of the Jurassic, Torvosaurus!
Torvosaurus was a genus of megalosaurid theropod that lived during the latest part of the Middle Jurassic and the Late Jurassic. The genus contains two described species found in North America and Europe

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 “terrible 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

Two more amazing Triassic reptiles. In this case from the Late Triassic Keuper Group of Europe. The huge phytosaur Nicrosaurus kapfii and one of the earliest plesiosaurs, Rhaeticosaurus mertensi
Part of my book of Triassic Tetrapods (currently in preparation)

Selected species of Dimetrodon.
Here are various sketches showing some species of Dimetrodon, which was a quite diverse genus during the Early Permian. The genus includes about a dozen of species
