Did all the dinosaurs live together in the same period?

They lived in a period of nearly 200 millions years, till -65 MY.
Eoraptor lived from -230 to -225 my. (that a 5 millions years span. It may seems short, compared to that 200 millions years. But keep in mind that humans have been around only for a couple of millions years, and homo sapiens - current humans - only for 300000 years. Which is my point: that 200 millions years span is far more than needed for species to appear, thrive, and disappear several times)
T-rex had been existing only for a couple millions years when that meteorite (probably) ended dynosaurs reign.
Between the death of the last Eoraptor and the birth of the first T-rex, there is twice as much time than between the death of the last T-rex and the birth of the first human!
Dinosaurs even underwent a massive extinction (i mean, before the KT one). The Trias-Jurassic extinction.
Sure, they are the big winner of that extinction (it is that extinction that lead to the radiative thriving of dinosaurs). Exactly as we, mammals, are the big winners of the KT one.
But exactly as the vast majority of the mammals species died during the KT extinction (even if the few that survived earned the Earth), the vast majority of already existing dinosaurs died during the Trias-Jurassic extinction).

Dinosaurs lived between 230 and 65 million years ago, in a time known as the Mesozoic Era.

While the dinosaurs lived during the Mesozoic Era there were various species that lived in the different time periods. As an example Allosaurus is as removed in time from the T-Rex as we are from the T-Rex. Dinosaur species that were dominant during the Triassic were no longer living in the Cretaceous. When flowering plants appeared new herbivore species evolved and those dinosaurs which were unable to adapt died out.

No, not any more than all fish live together the same time frames or that the age of mammals is made up of identical mammals all living together all at the same time.

No they did not. Using fossil evidence, paleontologists have identified over 500 distinct genera and more than 1,000 different species of non-avian dinosaurs. Dinosaurs first appeared about 240 million years ago (in the Triassic Period) and various types existed in different locations up until their demise about 65 million years ago (Jurassic Period). They had a very long run of existence, and they did not all live together.

....sure : such period lasted over 60 million years and evolution was awfully slow , untill a gigantic asteroid impacted the Earth in the gulf of Mexico killing all major animals .

Dinosaurs existed over hundreds of millions of years. They changed over time. Individual species thrived or died out or changed and were modified. The time scale was so large it is beyond our comprehension. We think of the pyramids as "old". We are not surprised that our society has changed since then. So now picture a time some 20000 times longer than this. Of course all of the different types of dinosaurs did not exist at the same time nor even within tens of millions of years of each other.

Sort of - they lived in the Mesozoic Era, which was about 66 million years long
Not in the same period. The same apartment.

No, varieties of dinosuar existed for miullions of years and not all types existed throughout that period.
