Spanning 145 to 66 million years ago, the Cretaceous period witnessed turtles as an already well-established and morphologically diverse reptilian lineage. These creatures possessed protective bony shells and occupied ecological niches ranging from small terrestrial habitats to expansive marine environments. Late Cretaceous seas hosted colossal species such as Archelon and Protostega, both achieving shell lengths of approximately 13 feet and demonstrating sophisticated adaptations for pelagic existence. Archelon dominated North American shallow seas, while Protostega specialized in consuming gelatinous prey. This 1.3-inch limb bone from Wyoming's Lance Creek Formation exemplifies the anatomical complexity of these ancient reptiles, offering paleontological insight into Cretaceous biodiversity and evolutionary success.
