The hair-like structure would prevent the egg/young from getting into a pouch. Also the beard is very thick. Also it's much too dangerous to try to lay the egg in a pouch when you don't really see what they're doing and with that size they have difficulties controlling the body. This could make it to a game of hazard what would pretty soon lead to extinction. The sea horse has a lot better control because of it's very small size.

The shark example was meant to portray how bigger sharks bear live young as they are too big to lay eggs. That applies for (almost) any vertebrate.

Ceadeus is actually very whale-like and has some similarities like the very long fins.

What you see (kind of) false is that the pouch is a very mammalian way as most animals that have a pouch are mammals. Only non-mammal of this kind that come to mind are the sea horses what are fish. And they are not reptiles.

I really don't know why they have beards, but that's just too unsafe for a reason.

The gills are just impossible as there is no turning back in evolution. When you lost something to evolve something else, something better it's gone. Whales could re-evolve the fins only because fins are much better than legs when you live in the water. And they are different to fins of a fish. While it may be of advantage if you have gills underwater, a lung can still get more oxygen and just coming to the surface from time to time is easier and more effective than to evolve gills again. Also as dragon-like monster it is very advanced to reptiles.

And the lifting to the surface is very easy if you compare them to any other possibility for an animal with lungs. Whales just do it because it's just logical to do it if you care for your offspring.
