Note: For campaign and challenge play, I highly recommend that the Psittacosaurus be installed as a companion to this mod, as it shares its dig site in the Yixian (pronounced like 'ee-shin' by the by, at least according to Google Translate) Formation and fleshes out that formation slightly more with unique yield items. That mod requires the Herbivore Dinosaur Pack, which is far superior to Claire's Sanctuary.

After an intense couple weeks of trying and failing to find a way to get this thing into a game by using the prefabs of other large theropods and after a grueling session of working around the idiosyncracies of the 'Claire's Sanctuary' files, it's here. This mod adds a new dinosaur to the game: Yutyrannus, a giant, 125 million year-old proceratosaurid from China that stands as the largest dinosaur yet known to have possessed feathers in life. It is unlocked on Isla Pena with a little over half a bar of reputation with the Science division in the campaign/at 3 stars in Challenge Mode.

This mod requires the 'Claire's Sanctuary' DLC and a mod called the Awesome Cobra Script Extender/ACSE, specifically the latest version of the mod (v1.1). The installation procedure is as follows:

• Download the latest version of ACSE/the Awesome Cobra Script Extender from https://github.com/OpenNaja/ACSE/releases/tag/1.1, the
  download link should read 'Awesome.Cobra.Script.Extender.zip'
• Extract the file. If you're using 7Zip, which is what I use for all of this, make sure you click 'Extract Here' instead of any of the other options. If a folder named 'ACSE' appears after you extract the file, you've installed it correctly and you can delete the .zip file (not the folder). If a folder named 'Awesome.Cobra.Script.Extender' appears, delete that folder (not the .zip file, you still need that) and try again.
• Download this very mod
• Either drag/drop or copy/paste the 'YutyrannusNL' folder to the following directory: 'steam\steamapps\common\Jurassic World Evolution\Win64\ovldata'. Do not rename the folder, and do not put the folder in any of the folders already inside of ovldata.
  

Depending on how many ACSE-reliant mods you already have installed, you may encounter a strange issue: the Yutyrannus's research icon may overlap with one of the pre-existing icons in the Medical Treatment menu, making the icon unselectable. To remedy this issue, follow these steps:

• Right click to leave the Medical Treatment menu and go back to the base research menu
• Enter another research submenu - Genetic Research is a good pick
• Right click to leave that menu
• Re-enter the Medical Treatment menu. The icon should now be selectable. If you are unhappy with the layout of the menu or it still does not let you click the icon, retry the process with a different submenu

Known Issues

• Stiff arms, the model was completed before rig editing was figured out
• Feathers are glossy in the rain - this is a quirk more than an issue, but it is worth mentioning
  

If you find any serious issues that aren't acknowledged above, please do report them; the more descriptive the reports the better, "game crashed please help" isn't something I can go off of very well.
