Physical Charateristics:
Hyphalosaurus (meaning "submerged lizard") is a genus of freshwater aquatic reptile, and a major part of the Jehol Biota. It lived during the early Cretaceous period (Aptian age), about 122 million years ago. It contains two species, H. lingyuanensis and H. baitaigouensis, both from the Yixian Formation of Liaoning Province, China. It is among the best-known animals from the Jehol Biota, with thousands of fossil specimens representing all growth stages in scientific and private collections.
Physical Charateristics: Tortoises ( /'t??r.t?s.?z/, Testudinidae) are a family of land-dwelling reptiles in the order Testudines. Like their marine relatives, the sea turtles, tortoises are shielded from predators by a shell. The top part of the shell is the carapace, the underside is the plastron, and the two are connected by the bridge. The tortoise endoskeleton has the adaptation of having an external shell fused to the ribcage. Tortoises can vary in size from a few centimeters to two meters. They are usually diurnal animals with tendencies to be crepuscular depending on the ambient temperatures. They are generally reclusive animals.
