👉 Micracanthorhynchina is a group of extinct, large, arboreal mammal-like dinosaurs that lived during the late Cretaceous period. They were characterized by their elongated forelimbs and long necks, as well as a distinctive skull with two sets of vertical ridges on the top and bottom surfaces. These animals are known for their large size, impressive build, and ability to climb trees in search of food.
