Marine reptile - Fossilised animal - Hyphalosaurus sp. - 56 cm - 30 cm

The Hyphalosaurus genus represents a group of freshwater aquatic reptiles from the early Cretaceous period, characterized by their elongated bodies and tails adapted for swimming. This fossil specimen measuring 56 cm by 30 cm indicates a relatively well-preserved individual, offering important anatomical information. Hyphalosaurus is classified within the order Choristodera and known for unique features such as long necks and paddle-like limbs. These reptiles inhabited lakes and river environments in what is now China, playing a niche role in their ecosystems. Fossils of marine reptiles like Hyphalosaurus provide vital data on the evolution and diversity of aquatic adaptations in Mesozoic reptiles, bridging gaps in understanding vertebrate transitions between land and water.
