Rodents are the smallest dinosaurs found so far. It is a herbivorous dinosaur that lived in the late Triassic (or early Jurassic). From 65438 to 0979, according to the fossils of five or six young rats found in a nest, the proportion of head, eyes, limbs and body is very large, which is the fastest growing part of young rats.
This little dragon fossil without tail is only 20 cm long, which is as big as a kitten, so it is named Rat Dragon. However, scientists later found that adult mice can grow to 5 meters long and weigh 120 kg. Scientists carefully compared young people with adults and found that young people have bigger heads, bigger eyes and rounder noses. Adults have smaller heads and eyes and narrower noses.
