Huayangosaurus
Huayangosaurus is a stegosaurian dinosaur from the Middle Jurassic of China. It was one of the smallest known stegosaurians, at just 4 m in length and 500 kg in body mass. Like other stegosaurians, Huayangosaurus was a quadrupedal herbivore with a small skull and a spiked tail. It bore the distinctive double row of plates that characterize all the stegosaurians. In Huayangosaurus, the plates were spike-like. Unique to the Huayangosaurus were the broader skull and premaxillary teeth in the front of its mouth. All later stegosaurians lost these teeth.

Huayangosaurus was an incredibly early stegosaurian, possibly the earliest known. Huayangosaurus fossils can be dated back 165 million years, some 20 million years prior to when Stegosaurus lived. At only 4 metres (13 feet) long, Huayangosaurus is also one of the smallest stegosaurians known.

#Archovember Day 22 - Kentrosaurus aethiopicus
Much smaller than its cousin Stegosaurus, Kentrosaurus aethiopicus was still a very unique stegosaur. From the Late Jurassic of Tanzania, Kentrosaurus had multiple means of defense: from a row of plates down its back that gradually merged into spikes, to longer spikes on the end of the tail, and even spikes on each shoulder! Well… probably. These two unique, broad-based spikes were not found attached to the animal. Classically, they were placed on the hips. However, the more recent discoveries of Gigantspinosaurus and Huayangosaurus had shoulder spines, so it is now typically placed on the shoulders.
Kentrosaurus was a herbivore and did not seem to do much chewing, instead swallowing its food in large chunks, probably also swallowing stones to help grind its food. It would have eaten low-growing food and fruit, though it may have also been able to rear up on its hind legs to reach higher vegetation.
There seem to have been two seperate morphologies of Kentrosaurus: one robust and one gracile. It is suggested that these represent sexual dimorphism, with the more common robust form being females and the less common gracile form being males. However, the ratio of common/uncommon may be skewed by the robust form being more easily fossilized.
Kentrosaurus aethiopicus lived alongside the small iguanodontian Dysalotosaurus, sauropods like Giraffatitan and Dicraeosaurus, theropods like Elaphrosaurus and Veterupristisaurus, and small mammals like Brancatherulum.

So Happy Birthday to Rei! Dino Au art!
Rei as a Gigantspinosaurus with Byakko's markings
I still need to figure what the lore for him would be but maybe he gets the markings after receving byakko's blessing? Or just he already had the markings they just turned green and the spikes became golden.
This actually makes him so much at risk of poaching, ooops. Angst potential uh.
Random facts about the species:
Name means "giant-spined lizard". Of course.
It was found in China. First fossil found in 1985 but it was mistaken for Tuojangosaurus. It was described in 1992 but only got recognized as a valid species in 2006
It is described as a medium- sized stegosaur. Estimated to be about 4.2 meters(14ft) and 700 kilograms (1500lb)
The shoulder spike is twice the length of the shoulder blade. Probably even bigger considering the covering it would have in life, what we see in the fossil now is just the bone core.
We actually have skin impression! They were described as rosettes with a central pentagonal or hexagonal scale, surrounded by thirteen to fourteen ridged smaller square, pentagonal or hexagonal scales.
It is the the most basal known member of Stegosauria but not the most basal stegosaur. Chungkingosaurus and Huayangosaurus are more basal (and both were also candidate species for Rei!)
Still no official lore for him so sorry for that!
Some art process under here

Stegosauria
The Stegosauria suborder consisted of herbivorous ornithischian dinosaurs who lived during the Jurassic to the early Cretaceous period. The earliest Stegosauria was Huayangosaurus.

Shunosaurus; lagartos de Shu
Shunosaurus ("lagarto de Shu") es un género representado por dos especies conocidas, y posiblemente una tercera, de dinosaurios saurópodos cetiosáuridos que vivierón a finales y mediados del período Jurásico, hace aproximadamente entre 165 a 159 millones de años, desde el Bathoniense al Oxfordiense, en lo que hoy es China. Compartió el territorio con otros saurópodos como Datousaurus, Omeisaurus y Protognathosaurus, el posible ornitópodo Xiaosaurus y el posible estegosauriano Huayangosaurus y el terópodo Gasosaurus.
Junto con el Saltasaurus; vendría a ser otro de los tantos sauropodos para hacer compañía al Brachiosaurus
