In our impression, most of the dinosaurs are unimaginably large creatures, but the primitive world is not only this kind of outrageous dinosaurs, there are also small pocket dinosaurs, the following Small Editor for everyone to sort out these pocket dinosaurs, let's take a look at it!
The tenth place , " Europaurus " , belongs to the sauropod suborder Macrosodonosaurus , which lived in northern Germany during the Late Jurassic. Fossils of Europaurus Hautiana found by paleontologists include more than 11 individuals belonging to different stages of development, with body lengths ranging from 1.7 m to 6.3 m. Because fossils of Hau's Europaurus were native to marine carbonate formations, these dinosaurs may have inhabited the islands and formed dwarf species due to the isolated environment of the islands.
The ninth dacian magyarosaur belongs to the sauropod suborder plesiosaurs and lived in Romania in the Late Cretaceous. With a body length of only 6 meters, geologists believe that Late Cretaceous Europe was covered by a shallow sea, while what is now Romania is located on an island known as Hatzig. Paleontologists believe that because of the isolated environment of the island, Dacia Magyarosaurus formed a dwarf species, much smaller than its inbreeds on the continent. Dacia Magyarosaurus was first discovered by "Dinosaur Baron" Baron Franz Nopcsa.
The eighth genus , Hajafruta " , belongs to the ornithischian family , living in the Late Jurassic state of Colorado, Usa. Paleontologists speculate that Hajafrutaluta was only 65–75 cm long and weighed 500 to 750 g, making it one of the smallest known ornithischian dinosaurs. Hagaflutaosaurus and other allodonosaur dinosaurs had canine teeth on their upper and lower jaws, and paleontologists believe that canine teeth could be used for fighting and self-defense.
The seventh genus , the theropod " , is a superfamily of theropod suborder Avala , living in Late Cretaceous Mongolia , with a body length of less than 40 cm and a femur length of only 5.26 cm. The forelimbs of the Avaraurus superfamily dinosaurs were generally short, with the second and third fingers degenerating, with only a developing first finger, and paleontologists speculated that the distant Chironae might have used its claws to dig up hard termite mounds.
The sixth genus , " Hesperus " , belongs to the theropod family " , living in The middle Jurassic Liaoning Province , China , with a body length of less than 40 cm , a femur length of only 4.32 cm to 6.62 cm , and a weight of only 110 g. In 2010, scientists from different fields in China and the United States formed a research team to study the fossils of Hesperus, and finally restored the feather color of Hesseosaurus by measuring and statistically restoring the size, length and shape of the melanoid body preserved by the Fossils of Hesch.
The fifth place [ Strange Liaoning Dragon ] belongs to the family Ankylosaurus suborder Noduleosaurus , which lived in Liaoning Province , China during the Early Cretaceous. The body length of the strange Liaoning dragon is only about 34 centimeters, but paleontologists believe that the fossils found so far may belong to the juveniles, so the adult strange Liaoning dragon may be larger.
The fourth place , " Short-feathered Chinese " , belongs to the theropod suborder " " , which lived in Liaoning Province , China during the Middle Jurassic. The fossils of the short-feathered Chinese feathered dragon not only preserve the complete skeleton fossils, but also preserve the feather imprints. With a body length of 30 cm, a skull length of only 4.32 cm, and a femur length of only 4.85 cm, it is one of the smallest known non-avian dinosaurs, with no long flight feathers on its hind limbs, so it may be better at running than its kind.
The third place [Hu Yaolong] belongs to the theropod suborder Panlong family, living in the Inner Mongolia Autonomous Region of China in the Middle Jurassic. Hu Yaolong and Ningcheng Tree Dragon are very similar, but the length of the tail vertebrae of the two is different, the length of the tail vertebrae of Hu Yaolong is only 70% of the body, while the length of the Ningcheng Tree Dragon is 300%. Hu's yaolong was only about 25 centimeters long, but had four tail feathers that were more than 20 centimeters long, and paleontologists speculated that Hu's yaolong had only 164 grams.
The second name , " Therapiaceae " , lived in the Middle Jurassic Inner Mongolia Autonomous Region of China , and paleontologists speculate that this dinosaur may have been a tree-dwelling animal. The body length is less than 20 centimeters, but paleontologists speculate that the fossils found so far may still be juveniles, so the body length of the adult Ningcheng tree dragon is uncertain. The Ningcheng Tree Dragon was named in 2002 by Chinese paleontologists.
The first [Honey-Sucking Honeybird] belongs to the order Swifts of the order Ornithischia and lives in Cuba. Hummingbirds can flap their wings 80 times per second and are able to hover in the air by rapidly flapping their wings. The body length is only 5-6 cm, and the weight is 1.8 grams. Most paleontologists currently agree that birds originated from the theropod dinosaurs of theropods, so dinosaurs also include birds, and honey-sucking birds are the smallest dinosaurs.
