Gansus is a genus of aquatic birds that lived during the Aptian age of the Early Cretaceous (Aptian-Albian) period in what are now Gansu and Liaoning provinces, western China. The rock layers from which their fossils have been recovered are dated to 120 million years ago.
It was first described in 1984 on the basis of an isolated left leg.
It is the oldest-known member of the Ornithurae, the group which includes modern birds (Neornithes) and extinct related groups, such as Ichthyornis and Hesperornithes.
he genus Gansus contains a single species, G. yumenensis, which was about the size of a pigeon and similar in appearance to loons and diving ducks.
It had many features common among modern birds, and also retained some basal traits such as its clawed wings.
Gansus was discovered in the form of a single fossil foot in 1981. Five more well-preserved fossils were found in 2003–2004 in mudstone at the site of an ancient lake at Changma, Gansu; the geological stratum in which the fossils were found is the Xiagou Formation. Their bodies had settled in anoxic mud and were soon covered with further extremely fine silty sediments. Without oxygen, their remains resisted decay: these specimens preserved remains of flight feathers and traces of the webbing between their toes.
In 2011, there were described nine additional specimens, that supported on the basis of a statistic analysis of the sternum and elements of the legs, the hypothesis that Gansus was a volant bird.
You et al. (2006) concluded that the anatomical characteristics of Gansus were similar to foot-propelled diving birds, such as Hesperornis (from the Cretaceous) and the loons (Gaviidae) and grebes (Podicipedidae).
On the other hand, Li et al. (2011) concluded that Gansus showed a more similar morphology to ducks.
Two years later, Nudds et al. (2013) showed that the pectoral limb length proportions of Gansus were most similar to swifts and hummingbirds (Apodiformes), while the pelvic limb length proportions fell within the modern birds (Neornithes), showing similarities with grebes (Podicipedidae), albatross (Diomedeidae) and cormorants (Phalacrocoracidae), suggesting that Gansus was both volant and capable of diving to some degree using either foot-propelled or, perhaps, both its wings and its feet for underwater locomotion.
Gansus was described as the oldest known ornithuran. The Ornithurae, however, has been given several very different definitions. In the definition used by You and colleagues (that is, the clade containing all living birds plus Hesperornis and Ichthyornis), Gansus is indeed the oldest known member. However, several birds from the older Yixian Formation and contemporary Jiufotang Formation are considered ornithurans under other definitions. Under any definition, all living birds, including taxa as diverse as ostriches, hummingbirds and eagles, are descended from basal ornithurans, many of which were semi-aquatic. It is now thought possible that all modern birds descended specifically from a semi-aquatic bird similar to Gansus. Thus, while Gansus is not necessarily a direct ancestor of today's birds, it is closely related to such an ancestral species.
This hypothesis was corroborated by later phylogenetic studies that included this taxon.
In the game, it is a duck-like waterfowl that lives near water and is slightly larger than a dodo.
It can swim like a duck, but it can fly.
They are friendly birds and will quickly fly to the sky to escape if attacked.
Taming
Coma tamed because it can be easily put into a coma.
It can be easily tamed, mainly on berries.
After taming
They can be raised like domestic animals like dodos.
However, it can be shoulder glued and can be carried on the shoulder.
It also has the ability to find out if there is water nearby.
As soon as it finds a nearby body of water, it can fly away and guide the player to that body of water.
As such, it is very useful in areas with limited water access, such as desert regions and Scorched Earth.
Because this bird tells the player where the waterside is.
