Fossil showing that some mammals preyed on some dinosaurs found in China.

It was a small dinosaur and dog-sized mammal, but it does play against the typical picture of all mammals being shrew-like and oppressed by their saurian overlords.

I don't want to be a complete "flat earther" about this, but how is it that so many revolutionary, exquisite and detailed fossils are suddenly showing up in China? Dinosaurs with feathers; birds with teeth, etc. I recall reading something recently about China engaging in "fossil forgery." It may be something to look into.
