Species: J.yangi
Animal Class: Medium
Standard Containment Procedures:
Groups of up to eight (8) J.yangi individuals are to be kept in containment pens featuring a minimum floor area of ten thousand (10000) square meters. These containment pens are to feature fencing of ‘low’ classification at minimum, however it is recommended that ‘medium’ class fencing is utilised for larger groups or for groups with aggressive J.yangi individuals. Fencing is to be checked on a weekly basis for any signs of damage or general wear and any found instances of either to be repaired by assigned maintenance staff as soon as possible.
The containment areas for J.yangi groups are to be made up of thickly foliated ground with a low upper-canopy to mimic the forests present in the Yixian formation. Alongside this a large flowing waterway is to be featured inside the containment pen to facilitate freshwater foliage browsing by J.yangi individuals. Feeding for J.yangi individuals is to consist of ten (10) kilograms of plant matter a day multiplied by the number of adult animals present in the containment area.
Recall procedures for J.yangi individuals follow standard Class D Ornithischian Containment Procedures. Usage of lethal force is allowable due to J.yangi’s size. Issuing of standard rifles and tranquilizer rifles is fully authorised and does not require the consent of the board of directors for usage in recontainment of J.yangi.
History & Description:
J.yangi is as close to a ‘standard’ basal Hadrosauriform as a park can put on display, standing at four point seven five meters (4.75m) in a straight line and weighing in at seven hundred and twenty (720) kilograms for an average adult individual. In terms of appearance J.yangi is somewhat unique for an animal of its size and weight in that it is primarily green, however this green is quickly broken up by a brown neck, upper back and tail with a creamy-white underbelly. This creamy white underbelly colour is present throughout other facets of J.yangi, mostly in its patterning with the striping on its limbs, spots on its body and the fish scale-like pattern on its tail all being in this same colour. Outside of this J.yangi has one striking feature, a pair of inflatable nasal sacks which have a striking almost neon blue colour, heavily contrasting the near black scales and beak around it. Unusually the nasal sack with this colouration is present in both male and female J.yangi individuals, with dimorphism between J.yangi’s two sexes being exclusively from the amount they can inflate these nasal sacks with males being capable of inflating it to much higher degrees than females.
J.yangi lacks a rich history of containment due to its relatively placid nature having been involved in minimal containment breaches, wild releases or civilian deaths. This calm and somewhat unconfrontational nature that J.yangi presents is reflected in its social structure and other behavioural habits, as J.yangi individuals in every group being relatively equal to each other with no directly observable hierarchy. Unusually this extends into mating season with males exclusively displaying using their nasal sacks with direct confrontation between more equally matched males being quite rare; in such cases these equally matched males display continuously in a contest of stamina. Such incidents can last for hours with one particular case lasting for nearly fifteen (15) hours with the commotion unintentionally causing a containment breach by a T.rex individual in a nearby containment pen (a transcribed video log of this incident can be viewed in attached document JY_BCHL_004).
At one star, J.yangi is not a ‘popular’ animal in terms of rating, however due to it being a common sight in parks exhibiting prehistoric wildlife it has become a household name with its striking pattern and colour palette being something most people can recollect with just the animals name. This has had the effect of making J.yangi the prehistoric equivalent of the modern Zebra in terms of recognisability and availability across the globe.
