North American Microraptor Disaster

The North American Microraptor Disaster is an event that occurred due to people bringing back extinct Microraptor species and bringing formerly fictional Microraptor species from films, books, etc (Prehistoric Park, etc) and accidentally introducing them to the modern North American environment.

Description
Depending on a species, Microraptor can be either about the size of a small quail to about the size of a very large turkey. While most species have feathers, only one species have only scales covering its body. Some species of Microraptors have very outdated-looking pronated hands that most other Microraptors species don't have. Some species of Microraptors have a very shrink-wrapped-looking appearance like many of the All Todays animals (reptilian elephants, etc), despite having muscles, etc. All known species of Microraptors are very docile and seem very tame towards any sapient species/beings, but are predatory towards native arthropods and other smaller animals. While (most) feathery species of Microraptors can glide, few Microraptor species such as the featherless scaly Microraptor and the ground Microraptor are completely flightless (or glideless) and are fully terrestrial.
