**Originally Listed At $550**

Northeast China, Lingyuan, Liaoning Province, Late Jurassic, 140 million years old. A handsomely framed Sinohydrosaurus lingyuanensis (also Hyphalosaurus lingyuanensis) fossil. This species is among the more recently discovered types. A marine lizard from the dinosaur fossil beds of Liaoning Province in the Peoples Republic of China, this species had its roots in a land-dwelling progenitor. The Sinohydrosaurus resembles the larger Keichousaurus which preceded it by 100 million years. Size: 7.25" W x 3.625" H (18.4 cm x 9.2 cm); 14.75" W x 12.75" H (37.5 cm x 32.4 cm) framed

While resembling a Nothosaur, this dinosaur differs in its osteological structure. Scholars have noted that it has no clavicles, but instead possesses a T-shaped interclavicle. The Sinohydrosaurus lingyuanensis would have enjoyed the fresh water in the volcanic regions of Late Jurassic. Given its osteological structure, paleontologists believe that this reptile from Lingyuan belonged to Lepidosaurs, as it is very similar to the lizard except its long neck. With 18 vertebra in the neck, it constituted a new genus and new species.

Provenance: ex-A Coin Exchange, Tarzana, California, USA, acquired at the Tucson Gem and Mineral Show in 2008
