Prompt used to create the image
Scientifically accurate paleoart of Minimocursor, a herbivore Neornithischia dinosaur from Tithonian–Berriasian times (149.2–137.05 million years ago). A small, lightly built two-legged plant-eater about the size of a large dog, with long hind legs for running. Reference: Minimocursor is a genus of basal neornithischian dinosaur from the Late Jurassic Phu Kradung Formation of Thailand. The type species is Minimocursor phunoiensis. Anatomy: short arms with five-fingered hands, a small head with a beak, and a long stiff tail held straight out. Full body in side view, whole animal visible, standing in a Late Jurassic river floodplain like the Phu Kradung Formation of northeastern Thailand, with conifers, cycads, tree ferns and ferns, no grass and no flowering plants. Natural history museum illustration style, realistic textures and natural daylight, muted natural colors. No text, no labels, no humans, no modern objects.

Minimocursor
There is no write-up for this dinosaur yet, but the scientific data below is complete.
Who lived alongside it
Dinosaurs found in the same rock formation as Minimocursor (Phu Kradung), so they lived in the same region at roughly the same time.

Uragasaurus

Mamenchisaurus
Formation data from the Paleobiology Database, counting only each genus's main formations. One formation can span hundreds of thousands to millions of years, so this doesn't mean any two of them ever met.
