This post is part of Debutniverse, a series where I watch just the first episode of various cartoons.

First episode title: Denver, the Last Dinosaur
How familiar with the show am I?: I hadn't heard of it before.

What happens when four teenage boys discover the only known living dinosaur in the present day? This show both asks and answers that question. In quite a lot of detail, since this first episode is over 45 minutes long!
