That is wrong. There were many dinosaurs during the Permian period, as it is the period where most of the reptiles emerged/evolved.
Here are some dinosaurs from the Permian:
Have a look on Wikipedia for some of these dinosaurs.
A recommended site is:

It has a page on 'Life', so have a look at terrestrial and marine biota.
There are definitely dinosaurs from the Permian period.
