The Dinosaurs lived in 3 Geologic time periods-The Triassic, Jurassic, and Cretaceous.
These 3 time periods where the three periods of the Mesozoic Era, which is also known as the Age of Reptiles.

Bjorn Ulvaeus currently lives in Stockholm. He did live in London for many years.
geologics aren't people, so they don't have a gender and don't have periods.
Many periods are named after places where rocks from those periods are found. For example the Jurassic period is named after the Jura Mountains in the Alps.
There are so many that it's hard to name just a few (there are 6 geologic time periods that existed before the Triassic after all). A few are dimetrodon, arthropleura, the trilobite, meganeura, gorgonops, and ctenorhachis.
The presence of fossils of different ages
The order of geologic time from smallest to largest is Phanerozoic, Proterozoic, Archean and Hadean (Deep Time). These four periods are called Eons which can be further subdivided into Eras, Periods and Epochs. Most people are more familiar with the periods such as Cambrian, Permian, Triassic, Jurassic and. Cretaceous and many more to numerous to mention. To learn more, Google geologic time scale.

Yes - many dinosaurs lived on land, for example.
The Mesozoic era is divided into three periods Triassic, Jurassic and Cretaceous. During the early Triassic, corals appeared. Seed plants dominated the land, in the northern hemisphere, conifers flourished. Glossopteris was the dominant southern hemisphere tree during the Triassic period. Many new dinosaurs appeared during the Jurassic period. Giant plant eating dinosaurs dominated the Earth. carnivores such as Allosaurus and Composognathus were plentiful. Many bird-like dinosaurs also thrived during this period. The Cretaceous period saw the heyday of the dinosaurs. Many new species of dinosaurs evolved during this period. New dinosaurs such as, the deadly t-rex and the extremely large Giganotosaurus appeared for the first time as did Triceratops and many others.
Yes there is evidence of Mesozoic dinosaurs in the form of fossilised bones of hundreds of clades, ranging from embryos to adult, eggs, coprolites and trackways. There are dinosaurs living today, the birds which are theropod dinosaurs. There is overwhelming evidence that birds derived from dinosaurs. There are now many fossils that show many types dinosaurs had feathers.
Dinosaurs lived between approximately 230 million and 65 million years ago, during the Mesozoic Era, which is divided into the Triassic, Jurassic, and Cretaceous periods. The last dinosaurs disappeared around 65 million years ago, likely due to a mass extinction event. This means that dinosaurs roamed the Earth for about 165 million years before their extinction.
The geologic time scale is divided into periods, which are then divided into epochs, which are further divided into ages. For example, the time of the dinosaurs lasted 3 periods (Triassic, Jurassic, Cretaceous), each period had 3 epochs (late, early, middle), and each age fit into one of those. Many epochs have more than 1 age associated with them. As for the basis for differentiating the eras, I'm not so sure. The only one I can say for sure is the end of the Cretaceous, which is when the dinosaurs suddenly became extinct due to a meteor impact. I think the divisions are based on significant, global-scale events that changed the world.
