As the sun sets upon a redwood forest 154 million years ago in what is now the Morrison Formation of Colorado, A lone male Stegosaurus stenops takes one of his juveniles to feed on some fern leaves as a few Mesadactylus chase fleeting insects around the tree trunks.

It doesn't snow in Paleo Pines, but what would our dino friends think if it did?

I bet they would be bewildered and look up at it with their big cute eyes.

Here's my two stegos, left to right: Shilo and Bluebell.

Yanbeilong ultimus Jia et al., 2024 (new genus and species)

(Back vertebrae of Yanbeilong ultimus, from Jia et al., 2024)

Meaning of name: Yanbeilong = dragon north of Yanmen Pass [in Chinese]; ultimus = last [in Latin]

Age: Early Cretaceous (Albian)

Where found: Zuoyun Formation, Shanxi, China

How much is known: Partial skeleton of one individual including several vertebrae and most of the hip.

Notes: Yanbeilong was a stegosaur. Cretaceous fossils of stegosaurs are rare, and they are generally thought to have died out in the Early Cretaceous (though some controversial remains may suggest otherwise). Yanbeilong is thus one of the youngest uncontested stegosaurs known.

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.

Dinovember 2024 Day 7: Bone Wars

Allosaurus and Stegosaurus, two dinosaurs from the Morrison Formation that were both described in 1877 and 1887 respectively by E.D. Cope, who was the chief rival of O.C. Marsh during the Bone Wars, a tumultuous time from 1877-1892 which also saw the discoveries of many famous North American dinosaurs such as Apatosaurus, Camarasaurus, Coelophysis, Diplodocus, and Triceratops…with the notable e caption of Tyrannosaurus, the continent’s most iconic dinosaur.
