A New Basal Neornithischian Dinosaur from the Phu Kradung Formation (Upper Jurassic) of Northeastern Thailand

An exceptional articulated skeleton of a new basal neornithischian dinosaur, Minimocursor phunoiensis gen. et sp. nov., was discovered in the Late Jurassic Phu Kradung Formation at Noi locality, Kalasin Province, Thailand, highly productive non-marine fossil vertebrate locality Khorat Plateau. It is one best-preserved dinosaurs ever found Southeast Asia. nov. shows combination both plesiomorphic and apomorphic characters resembling those to Early Cretaceous small-bodied ornithischians from China: low subtriangular boss projected laterally on surface jugal, brevis shelf ilium visible lateral view along its entire length, distinct supraacetabular flange present pubic peduncle ilium, prepubis tip extends beyond distal end preacetabular process manus digit formula ?-3-4-3-2. The phylogenetic analysis that this dinosaur among most neornithischians. This study provides better understanding early evolution taxonomic diversity
