A trillion years is 1,000,000,000,000 years.
In astronomy, it is probably a meaningless concept, because according to our current understanding of the universe, space and time began with the Big Bang around 14 billion years ago. So, looking back, there is no 15 billion years or more in astronomy.
Looking forward, there is too much uncertainty about the amount of matter in the universe to judge whether it will continue to expand and eventually burn away, or reverse into a big crunch which may be followed by Big Bang 2. However, there will be no link between our universe and universe 2. So whichever way it works out, current theories suggest that the universe as we know it will not survive a trillion years.
So many questions to answer, so little time!
Dinosaurs have been extinct for approximately 65 million years. Humans shared a common ancestor with monkeys about 6 million years ago, however Humans as such have only been around for roughly 40 thousand years.
A million or more years best fits the concept of geologic time. Geologic time spans millions to billions of years and is used to describe the immense length of time over which Earth's processes have occurred, such as the formation of mountains, evolution of species, and movement of continents.

Claudius Ptolemy, also known as Ptolemy, was a Greek-Roman mathematician, astronomer, and geographer who lived in the 2nd century AD. He is most famous for his work "Almagest," a comprehensive mathematical and observational treatise on astronomy that influenced Western and Islamic astronomy for over a thousand years. Ptolemy's geocentric model of the universe, with Earth at the center, dominated astronomy until the heliocentric model proposed by Copernicus in the 16th century.
Under the current "short scale" of numeration, a "trillion" is one thousand billion or 1012. (The superceded "long scale" used names that increased by a factor of one million, making the old billion 1012 and the old trillion 1018.)
A thousand million years equals 1 billion years.
