Dinosauroids

The archon, or Dinosauroids as classified by the SPDF or sapiens reptiliae are an advanced race of beings that lived on planet Earth at least 3 million years ago. Their civilization lasted for about 20 million years and possibly even longer.

Properties
The archon are the result of a radical shift in evolution after the K/T mass extinction about 66 million years ago. As most of the dinosaurs had been killed off, the last of their kind struggled greatly to survive, and the collective trauma their species suffered caused a mutagen in their DNA to trigger, accelerating their evolution. Their bodies became smaller, they cast off "dead weight" such as spikes, enormous tails and wings and their bodies became more "compact", allowing for much more efficient biological processes. Their brains developed further and their bodies became more humanoid, but they were much stronger than current-day humans and stood about 2.2m to 2.5m tall. In the end, the archon developed a form of ESP (Extra-Sensory Perception) that enabled them to see "the pattern of all that is"; the ability to foresee the future using a logical deduction of all patterns, the way the patterns overlap and repeat themselves throughout all of time, for all eternity and after. The archon had lifespans of about 10.000 years, as opposed to the estimated 70-100 years of most humans.

Sage of Thought
A notable archon, the Sage of Thought, studied for thousands of years before coming to the realization that the K/T mass extinction would most certainly happen again.
