I got a 3D Printer! I have an idea for a tabletop Dinosaur survival game - would anyone be interested in such a thing? The dice are my own sculpt featuring dromaeosaur claws for 1 and 2, and theropod footprints for 3-6. The figurine is a Citipati oviraptorosaur model I made, printed at roughly 1:60 scale on a 30mm base. More to come.

Heyuannia huangi bears the distinction of being the first oviraptorid found in China (the family had previously only been known in Mongolia.) It was a medium-sized oviraptorid, with a toothless, short and deep snout, and short arms and digits. Multiple fossils have been found of this species, including one which may retain possible reproductive organs. Heyuannia fossils also include hundreds, if not thousands of eggs. Preservation of the pigments biliverdin and protoporphyrin in the eggshells of these eggs indicate that they were blue-green in color. This coloration allowed for both camouflage and sexual signalling, as well as protection from the harsh UV light of the desert sun.

Two species of Heyuannia are known, H. huangi (drawn here) from the Dalangshan Formation and H. yanshini (originally named Ingenia) from the Barun Goyot Formation. The Late Cretaceous Dalangshan Formation of China is mainly known for Heyuannia and its eggs. The only other fossils from this location are teeth from an indeterminate tyrannosauroid, and the partial skeleton of an indeterminate lambeosaurine hadrosaurid.
