Osteology and phylogenetic relationships of a new small maniraptoran from the Upper Jurassic of Wyoming
A recently discovered small maniraptoran from the Morrison Formation of Wyoming provides new evidence for the placement or small Jurassic maniraptorans in theropod phylogeny. The specimen, WDC DML-01, is one of the oldest known taxa to be referred to the Troodontidae, estimated to be about 70% compl...
