Here the results from a stream we had some time ago where we speculated about dinosaur reproductive behaviors. A topic that I think is rather fascinating but is rarely touched upon (cowards!).

You see here six genera in the act.

Utahraptor, Turiasaurus

Hesperosaurus, Therizinosaurus

Spinosaurus, Gastonia

This species of stegosaurus, Hesperosaurus myosin, nicknamed “Stephenie”, is one of only three almost 100 percent complete stegosaurus fossils in the world. She has 80% of her original bones, taking over 9000 hours of restoration. It shows healed rib fractures and bite marks showcasing an intimate look at daily struggles for survival in the late Jurassic world. Stephanie was discovered in 2022 in Wyoming and has a remarkably complete skull that includes an intact brain case.

Strange Symmetries #11: Step Up To The Plate

Stegosaurs are some of the most popular and recognizable dinosaurs thanks to their unique appearances, with small heads, elaborate back plates, and spiky thagomizer tails.

Closely related to the ankylosaurs, they first appeared in the mid-Jurassic about 170 million years ago. While they lasted until at least the mid-Cretaceous (~100 milion years ago), their heyday was in the latter half of the Jurassic, ranging all across Asia, Europe, Africa, and North America – and the North American species like the eponymous Stegosaurus developed especially elaborate plates in a distinctive asymmetrical pattern, not arranged in pairs like most other stegosaurs but in alternating rows along each side of the midline of their backs.

Hesperosaurus mjosi lived around 156 million years ago during the late Jurassic, in what is now Wyoming and Montana in the Western United States. It was closely related to Stegosaurus but was a little older and a little smaller, about 5-6m long (~16-20').

Much like its more famous relative its plates seem to have alternated along its back, which may have been an adaptation to maximize visible surface area while minimizing the number of plates, saving on the energy needed to grow such large elaborate ornamentation.

Hesperosaurus might also represent a rare case of possible sexual dimorphism in non-avian dinosaurs, with wider more rounded plates potentially interpreted as belonging to males and taller pointed plates belonging to females.

Day 14 of Dinovember; a group of Hesperosaurus enjoy a dip and a drink in the shallows.

I’m not sure why, but this is one of my favorites so far ❤️ Maybe cause it’s more simple that most of the others. It does have a lot of white space in the foreground, but I think that’s ok here.

EDIT, 1/11/22: This entire Dinovember series has been compiled and is now available for purchase on Gumroad! The pages can be printed, or thrown into a digital program! Check it out HERE!

I’m also quite fond of stegosaurs. From top to bottom: Ferganastegos, Hesperosaurus, Gigantspinosaurus, Miragaia, Huayangosaurus, and Lexovisaurus (with guest appearance by Eustreptospondylus in the back).
