Ornitholestes hermanni (Osborn 1903, 1917, 2m, incomplete skeleton, Late Jurassic) According to Wikipedia,
"All published cladistic analyses have shown Ornitholestes to be a coelurosaur as defined by Gauthier. " In the large reptile tree Ornitholestes nests between Compsognathus and Microraptor, yet close to Tianyuraptor in the lineage of Tyrannosaurus. The skeleton shown here was restored based in the AMNH restoration, which may not be accurate with regard to the number of cervicals and dorsals.
Ornithologist Percy Lowe hypothesized in 1944 that Ornitholestes might have borne feathers. As a close relative of Microraptor, Ornitholestes probably had long wing feathers.
