Archelon is an extinct marine turtle from the Late Cretaceous, and is the largest turtle ever to have been documented, with the biggest specimen measuring 4.6 m (15 ft) from head to tail and 2.2–3.2 t (2.4–3.5 short tons) in body mass. It is known only from the Pierre Shale and has one species, A. ischyros.

Archelonhad a leatherycarapaceinstead of the hard shell seen in sea turtles. The carapace may have featured a row of small ridges, each peaking at 2.5 or 5 cm (1 or 2 in) in height. It had an especially hooked beak and its jaws were adept at crushing, so it probably ate hard-shelledcrustaceans,mollusks, and possibly evensponges, while slowly moving over the seafloor. It also potentially consumed other animals, whilst swimming closer to the surface, likejellyfish,squid, ornautiloids. However, its beak may have been better-adapted forshearingflesh, with fish being another possible prey choice. With its large and strong foreflippers,Archelonwas likely able to produce powerful strokes necessary for open-ocean travel and, if need be, escape from fellow marine predators. It inhabited the northernWestern Interior Seaway, a mild to cool temperate area, dominated byplesiosaurs,hesperornithiformseabirds, andmosasaurs. It may have gone extinct due to the shrinking of the seaway, increased infant mortality rates (in the sea), higher instances of egg and hatchling predation (on land), and a rapidly cooling climate.

Nowadays, we produce the truely Immortal Archelon ischyros, it has a real skin touch, vivid movements...It can be used in a variety of Settings, aquariums, historical museums, theme parks, indoor and outdoor exhibitions, etc. 

In addition to dinosaur exhibitions, we will also do animal exhibitions for major shopping malls and parks. Our simulated animals are all 1:1 restorations, as if they were given life. All animals are made of simulated fur and have movements.

We not only do modern animals, but also primitive animals, such as simulated mammoths, simulated saber-toothed tigers, etc. Design and make different animals according to different scenes.

Our products are exported to Europe and America. We will establish offices in France and Canada to provide customers with high-quality after-sales service.

AMODINO CHINA is the professional manufacturer of designing and producing animatronic models . We have specialized in this field for 20 years .Welcome to contact us for your exhibitions of animatronic animals ,animatronic dinosaurs and animatronic insects.
