Dinosaur Skeleton - Screen Lock.
Who among us did not like dinosaurs? These majestic extinct creatures like many. The appendix contains pictures of dinosaur skeletons. They will adorn your unlocking screen, and the app will be useful and easy to use!
Fossil skeletons of dinosaurs are almost always the only paleontological material on which scientists try to recreate the appearance of ancient lizards. A characteristic feature of skeletons dividing dinosaurs into two main groups is the structure of pelvic bones. In the dairy herds dinosaurs, the clubbone bones are directed upwards, where they are connected with the cross, the buttocks are down and back, and the pubes are directed forward and downward. In the bird's eye dinosaurs, the buttocks and clubbones are arranged in the same way, and the pubic bones have two branches directed in different directions: one is forward and the other is parallel to the buttocks.
At present, the discovery of a large species diversity has made it difficult to imagine a universally agreed list of distinctive features of dinosaurs; Almost all the dinosaurs that are discovered today share certain changes in relation to the hereditary skeletal archosaure. Although some later dinosaur groups showed signs of further change in common features, they are considered to be typical dinosaurs; Such common features between different taxonomic groups are called synapomorphy.
Synapomorphy of dinosaurs includes an elongated crest on the humerus or upper bone of the hand for the possibility of attachment of delto-superficial muscles; Protrusion in the back of the iliac or the pelvic bone; Leg or bone of the leg, which has a wide lower margin, as well as a projection on the tibia that forms the lower part of the ankle joint.
