Hacker Bird (Restoring 3D Model)
Phorusrhacidae is a large carnivorous bird species. The closest relative to them today is the crane family. The terror bird, also known as the terror bird, is a bird like carnivorous animal that lived alone during the same period as the saber toothed tiger. It is about 1-3 meters tall. Terror birds have hard leg bones and strong muscles, which can completely crush the bones of medium-sized prey and slowly feed on the nutrient rich bone marrow in the prey's bones. According to scientists' estimates, terror birds can reach speeds of up to 97 kilometers per hour, and the extinction of terror birds is believed to be related to wolf packs and disasters.

Ancient Kikushi (3D Restoration Animation)
Kikushi, a collective term for cephalopods and ammonites in the phylum Mollusca, is a group of extinct marine organisms. Kikushi lived from the early Devonian to the late Cretaceous period, and its shell is often preserved in the form of fossils in the strata. The outer shell of ammonite is a single petal, consisting of three parts: the fetal shell, the gas shell, and the living room. It usually spirals around the fetal shell along a plane, with each revolution forming a spiral ring. Adult ammonite shells generally have 5 to 9 spiral rings, symmetrical on both sides, and can be straight, curved, or even irregular.
