So science is constantly changing things. Like Eosinopteryx. Which was originally classified as a troodontid, so I put it in my list for ADAD. But then it got reclassified as an avialan, So today’s dinosaur is a bird! Hooray! If it was not an avialaen, it could have been a primitive paravian as well, which is the group we begin today now that we’re done with oviraptorids. It is only known from one fossil specimen, so the confusion on its classification is fairly standard. It lived in the Oxfordian age of the Late Jurassic, about 160 million years ago. It was found in the Tiaojishan Formation of Liaoning Province, China. It was about 30 centimeters long, making it quite small if it wasn’t an avialan. The tail was fairly short and the wings were the same size as Anchiornis huxleyi, and it had hind wings on its lower legs and feet. This could mean that the origin of flight is a much more complex phenomenon than archaeopteryx -> birds; however, given various dinosaurs such as Microraptor, this is not much of a surprise.
