Anchiornithidae is a family of small, feathered dinosaurs that lived during the Late Jurassic period. These creatures are significant for their bird-like features, suggesting an early stage in the evolution of flight. Anchiornithids had long feathers on their arms, legs, and tails, with some species displaying evidence of four wings, potentially used for gliding or balance, which making them crucial to understanding the transition from dinosaurs to modern birds. The uniqueness of this specimen lies in its open mouth, much like the logo of Jurassic Park, where the arrangement of the teeth can be easily observed. Each tooth is still very sharp and reflects light. The specimen comes with pre-preparation photos to prove that it is completely natural. These small bones, teeth, and claws have been perfectly preserved for tens of millions of years, showing impressive color variations. With careful preparation and the preservation of natural bones, it is undoubtedly a specimen worth collecting. The bottom of the matrix was damaged during shipping, but the fossil itself was not affected. Before shipment, I will reinforce the back of the matrix with a piece of wood and properly package it to ensure its safety. I sincerely recommend this to every collector who has a strong interest and passion for dinosaurs..
