Interesting dino-mite Haplocheirus facts!

They were members of the kingdom Animalia, phylum Chordata, and clade Theropod. The oldest known Alvarezsauroid called Hap was a genus of Maniraptoromorph theropod dinosaur. It was in the year 2010 that the fossil of this dinosaur was found which was probably 160 million years ago. The Haplocheirus fossil was found from the Shishugou Formation in the Junggar Basin of the northwestern region of China. H. sollers. Paleontologist Jonah N. Choiniere was a member of that research team that worked on the excavation of the fossils of this dinosaur They were different from Alvarezsauroid features in terms of using the three-fingered hand for skillful activities, which the Alvarezsauroid was unable to perform. Many paleontologists are of the opinion that Haplocheirus has evolved many times from the Mesozoic Era. They were like an early genus of the bipedal dinosaurs called Alvarezsaurs. It mainly fed on insects and the hands were very useful for the purpose. As a small dinosaur Haplocheirus must have been careful of Asian theropods such as Sinraptor and Monolophosaurus. Haplocherius is very different from the features of other dinosaurs of their time because of its relatively very early origins which are about 63 million years because of alvarezsaurs which were known later and more advanced forms of cretaceous. Haplocherius is also predated by 15 million years from the famous dino-birds Archaeopteryx who was the first birds-like dinosaur with feathers.
