KT is a Metaroom created by Ghosthande and released for the CCSF 2009. It is named for the K-T boundary, and consists of both a subterranean level and an upper level which is home to a variety of flora and fauna.
"KT is a fairly large, prehistoric-themed metaroom (or more accurately, a partial world) complete with dinosaurs, buried fossils, ancient monoliths and lush tree ferns. It comes with its own background music as well as a variety of new critters, plants and other agents, all of which utilize original 3D graphics." -- Breeders Beware.
You can download KT from Breeders Beware.
There are also several additional elements which are obtainable by using the temple cauldron.
The Bone Cave
For the CCSF 2010, Ghosthande released an expansion known as The Bone Cave as an addon for KT. It adds an additional cave to the metaroom along with many other new features.
"A new cave system has been discovered deep below the surface of KT! The tar pits, known as the Bone Cave, are home to a few previously undiscovered life forms specially adapted to the subterranean tomb, and the caves show further hints of the planet's intelligent inhabitants, including ancient magic such as the Medicine Rattle and even a tool to help transform the surface into a more peaceful abode: the mystic plaque has the ability to convert the dangerous Rexes into harmless vegetarians and dispel the evil Banshee magic that lingers in the Temple of Banubey." - Ghosthande

Warning: Before you inject The Bone Cave into your world, you must highlight it in the Agent Injector and click the 'remove' button. This will clean up any old scripts in the metaroom so they can be replaced. The Bone Cave may now be injected safely into the world.
