Dead Rocks

Even though it isn't part of series 1, it is set during series one, and is the shows Christmas special. It is the only episode to not feature an incursion, anomaly, or any part of the show. Instead, it is set around the time that Kevin, Sam, and Kiera briefly left the team after the events in A Sight to See. It focuses on each of them going to different places to uncover fossils. Kevin goes to Antarctica to discover a new species of almost entirely aquatic spinosaur, while Sam and Kiera go to Morocco, to find a semi-aquatic abelisaur. The end of the episode features a brief look into the animals lives, without anomalies, and without people, just living their lives.
