Guy becomes dinosaur in a coma

I'm trying to remember a book or a series I read when I was a teenager (early to mid 2000s) that featured a guy who was a dinosaur but knew he had been a human before. I think he was in a coma or something and his consciousness was transferred into a dinosaur. And he was trying to get back to his real life. He also encountered other dinosaurs who were people and would communicate with them telepathically (maybe.) I've done some searching already, and I don't think it's the Dinoverse series.
