Archelon is the largest turtle ever to have been found on our planet. It likely weighed 4,850 pounds and streached a massive 13 feet between the tips of it's flippers.  The name comes from the greek, meaning "ruler of turtles".  Researchers have suggested that this animal, discovered in South Dakota in the 1970's could have been 100 years old when it died while bruiting on the sea floor.  In life, this majestic creature used it's strong jaws for feeding on the abundant mollusks floating in the water column of the interior seaway.

Our specimen Is mounted in a lively diving posting. It comes with floor mounting assembly or can be suspended as a hanging mount.

The Hesperornithiformes were a group of flightless, aquatic birds that thrived along side the dinosaurs in the subtropical coastal areas of laramidia. Diving in the water for their food much like modern penguins, their teeth were uniquely adapted for hunting fish.  Fossil evidence suggests that Hesperornis had lobed toes that helped it power though the water while hunting and evading predation.

During the days of North America's vast interior seaway, marine reptiles like the mosasaurs were predators at the top of their food chain.  The teeth of Prognathodon were well suited for eating a variety of prey animals which were abundant in the inland sea such as large fish, molluscs and  sea turtles.  Our specimen was discovered in the Mancos shale of Souther Colorado, not far from the native american sites at Mesa Verde National Park.

Soaring above the vast interior seaway, miles from the shoreline, large populations of Pteranodon feasted on the abundant fish far from the reach of terrestrial predators like the dinosaurs and crocodiles that lived in the Cretaceous.  The largest of these great flying reptiles was P. longiceps, with a wingspan of nearly 23 feet.  Discovered in the NIobrara Chalk formation of Kansas, this classic mesazoic flyer is posed in a diving position as if flying towards the water, hunting its next meal.
