Silurian Ark

The Silurian Ark is a large starship created by the Earth-based Silurian civilization during the final days of their rule.

Background
These large roughly spherical shaped craft are able to hold thousands of crew in hibneration pods and are able to hold an entire self-contained ecosystem for animals to thrive. Some parts resembled outside planetary environments that were a near perfect replica of an environment though a keen observer was able to sample the air and detect metallic content in the air. Another example of the ships true nature is present in these environments as underneath the soil and sand were metallic plates. Its engines are powered through hydroelectric means with a large ocean that used waves as a form of energy.

A computer system is present that allows easy access to information and included a teleport system to any area of the ship. The control deck serves as the command centre for the entire ship and included an automated piloting system that locked the target for the vessel. Piloting of the ship involved parallel bio-compartments chairs that required the users to be of the same gene-chain.

History
This craft's creation is dated to the end of the Silurian's rule of the planet Earth. At the time, they discovered an object that was forecasted to collide with their homeworld. The majority of their race entered into hibernation though some of their kind created a large spaceship designed to hold their people and a large number of Dinosaurs. After the ship launched, it travelled in space where the Silurian preserved dinosaurs managed to thrive except for one species. Whilst in hibernation, the ark was boarded by Solomon who determined its cargo to be of high value that he could sell. After boarding the ship, he had his two robots wake up a few of the Silurians at a time and disposed of them when they refused to give him the dinosaurs. This led to the entire crew of thousands of Silurians being killed but their unique piloting method meant that Solomon was not able to alter the craft of the ship which was heading towards Earth.

Eventually, it managed to arrive near Earth orbit where its trajectory caused Humans to determine it was a threat. Thus, they intended to destroy it with a barrage of missiles. In this time, the Eleventh Doctor learnt of the ships existence and was determined to save it. He took Queen Nefertiti, John Riddell, Amy Pond, Rory Williams and Brian Williams to the ship where he encountered Solomon. The Doctor ultimately placed the Ark's signature onto Solomon's ship causing the missiles to target it and thus sparing the Silurian vessel. (DW: Dinosaurs on a Spaceship)
