Aalenian

The Aalenian is a subdivision of the Middle Jurassic Epoch/Series of the geologic timescale that extends from about 174.7 ±0.8 Ma to about 170.9 ±0.8 Ma (million years ago).

Crocodyliformes

Crocodyliformes is a clade of crurotarsan archosaurs, the group often traditionally referred to as "crocodilians".

See Xintiangou Formation and Crocodyliformes

Geological formation

A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics (lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column).

See Xintiangou Formation and Geological formation

Limestone

Limestone (calcium carbonate) is a type of carbonate sedimentary rock which is the main source of the material lime.

See Xintiangou Formation and Limestone

Lungfish

Lungfish are freshwater vertebrates belonging to the class Dipnoi.

See Xintiangou Formation and Lungfish

Middle Jurassic

The Middle Jurassic is the second epoch of the Jurassic Period.

See Xintiangou Formation and Middle Jurassic

Mudstone

Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds.

See Xintiangou Formation and Mudstone

Osteichthyes

Osteichthyes, also known as osteichthyans or commonly referred to as the bony fish, is a diverse superclass of vertebrate animals that have endoskeletons primarily composed of bone tissue.

Plesiosaur

The Plesiosauria (Greek: πλησίος, plesios, meaning "near to" and ''sauros'', meaning "lizard") or plesiosaurs are an order or clade of extinct Mesozoic marine reptiles, belonging to the Sauropterygia.

Protoxinjiangchelys

Protoxinjiangchelys is an extinct genus of xinjiangchelyid turtle known from the Early to Late Jurassic of China (Xintiangou Formation and possibly also the Shaximiao Formation). Xintiangou Formation and Protoxinjiangchelys are Jurassic China.

Sandstone

Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains, cemented together by another mineral.

Sanxiasaurus

Sanxiasaurus (meaning "Sanxia lizard", after the Three Gorges, Chinese Sanxia, of the Yangtze River) is a genus of neornithischian dinosaur from the Middle Jurassic Xintiangou Formation in the Chongqing Municipality of China. Xintiangou Formation and Sanxiasaurus are Jurassic China.

Shaximiao Formation

The Shaximiao Formation is a Middle to Late Jurassic aged geological formation in Sichuan, China, most notable for the wealth of dinosaurs fossils that have been excavated from its strata. Xintiangou Formation and Shaximiao Formation are Jurassic China and Jurassic System of Asia.

Sichuan

Sichuan is a province in Southwestern China occupying the Sichuan Basin and Tibetan Plateau between the Jinsha River on the west, the Daba Mountains in the north and the Yungui Plateau to the south.

Sichuan Basin

The Sichuan Basin, formerly transliterated as the Szechwan Basin, sometimes called the Red Basin, is a lowland region in southwestern China.

Temnospondyli

Temnospondyli (from Greek τέμνειν, temnein 'to cut' and σπόνδυλος, spondylos 'vertebra') or temnospondyls is a diverse ancient order of small to giant tetrapods—often considered primitive amphibians—that flourished worldwide during the Carboniferous, Permian and Triassic periods, with fossils being found on every continent.
