Top Ten Dinosaur and Fossil Finds: Most Viewed of 2009

Large, "lost," or simply unusual, a bevy of prehistoric beasts were brought to life in National Geographic News's most popular paleontology stories of the year.

Young dinosaurs weren't Mini-Me versions of their parents, evidence presented in October suggests—meaning that up to a third of dinosaur species may be misidentified.

7. Tiny "T. Rex" Found —150-Pound Species Came First
No heavier than a small man, Raptorex was Mini-Me to T. rex's dinosaur Dr. Evil. But in this case, the tiny gave rise to the titanic, researchers said in September.

1. "Missing Link" Found: Fossil Connects Humans, Lemurs?
The 47-million-year-old, exceptionally preserved primate fossil "Ida," unveiled on May 20, was hailed by some as a major discovery in human evolution.
