Sinornithoides was - you guessed it - another troodontid from Asia. Specifically it was found in the Ejinhoro Formation of Inner Mongolia, China, and lived in the Aptian to Albian ages of the Early Cretaceous, about 113 million years ago, making it a little older than our typical troodontids. It would have been about 1.1 meters long and less than a meter high (more like half a meter high), and it was one of the most completely known troodontids in 1994 (which wasn’t saying much, as troodontids are typically known only from teeth.) It had a long and pointed skull, however it was short compared to the rest of the body.
WHOOOOPPPS I doubt they were this flexible/would’ve just scratched with their hands - I just really wanted to use that vulture sketch as a reference and Sinornithoides seemed like a good idea at the time
