Sinocyclocheilus yimenensis (common name: Yimen golden-line barbel) is a species of cave fish in the family Cyprinidae. [1] [2] [3] It is endemic to Yunnan province in southern China. Its specific name yimenensis refers to the Yimen County where its type locality is. [2]
It grows to 10.5 cm (4.1 in) standard length and has a scaled, elongated body. The colouration is golden with a darker back and with some dark speckles. [2]
The type locality is an exit of a subterranean stream. [2]

The tench or doctor fish is a fresh- and brackish-water fish of the order Cypriniformes found throughout Eurasia from Western Europe including the British Isles east into Asia as far as the Ob and Yenisei Rivers.

Sinocyclocheilus is a genus of freshwater fish in the family Cyprinidae that is endemic to Guangxi, Guizhou and Yunnan in China. Almost all of its species live in or around caves and most of these have adaptions typical of cavefish such as a lack of scales, lack of pigmentation and reduced eyes. Several species have an unusual hunchbacked appearance and some of the cave-dwellers have a "horn" on the back, the function of which is unclear. In contrast, the Sinocyclocheilus species that live aboveground, as well as a few found underground, show no clear cavefish adaptions. They are relatively small fish reaching up to 23 cm (9.1 in) in length. The individual species have small ranges and populations, leading to the status of most of the evaluated species as threatened. Many species populations in the genus have yet to be evaluated by the IUCN.

Tonganosaurus is a genus of mamenchisaurid sauropod dinosaur, similar to Omeisaurus. It is known from one specimen consisting of twenty vertebrae, a front limb and pectoral girdle, and a complete hind limb with partial hip. It was discovered in the Yimen Formation, China. The horizon of the specimen and the age of the Yimen Formation is controversial. The formation has been divided into three levels, and Tonganosaurus appears to be of late Early Jurassic (Pliensbachian) age. Tonganosaurus is the oldest known member of the mamenchisaurids, being almost 15 million years older than the next-oldest members of the group. It was first named by Li Kui, Yang Chun-Yan, Liu Jian and Wang Zheng-Xin in 2010 and the type species is Tonganosaurus hei.
