Of course it could--Why would it not be able to be something extinct? There's no reasoning in any of the books or interviews with Rowling that would suggest otherwise, and as it is a patronus, not the actual animal, it makes no sense that it could not be such an animal.
To obtain the Stag Patronus in Pottermore, you must complete the Patronus Charm quiz. This quiz assesses your personality through a series of questions, ultimately determining your Patronus based on your responses. The Stag is one of the possible Patronus forms you can receive, symbolizing strength and protection. If you wish to increase your chances of getting this Patronus, consider answering the quiz questions with confidence and positivity.

Yes its very possible
It was not possible for a male dinosaur to lay eggs. That would be like getting a male dog to have puppies... It's not physiologically possible.

There are several contenders. So-called "Ultrasaurus" may have passed 100 tons. He was sort of a Brachiosaurus on steroids, but he's known only from a single massive thighbone. Then there's Seismosaurus ("earthquake-causing dinosaur") and "Supersaurus." New bones are still being discovered and animals inferred from them. As we learn more about dinosaur physiology, it will be possible to predict a maximum possible size beyond which no dinosaur could grow.
No, however, some dinosaurs did have feathers.
becoming pro and being pro are not the same thing because its like syaing that barney became a dinosaur and a famous dinosaur are the same thin. its not humanly possible.
