miss him, and I needed to honor him in some way. I couldn't not do it."

Among the skills needed for one to discover a new species of crocodile is, apparently, a keen eye.

Not that the fossilized crocodile head is smallit took four men to lift it. But other experts had seen the fossil without realizing it was a new species. Brochu points out that the Nairobi collection is "beautiful" and contains many fossils that have been incompletely studied. "So many discoveries could yet be made," he says.

In fact, this isn't the first time Brochu has made a discovery involving fossils from eastern Africa. In 2010, he published a paper on his finding a man-eating horned crocodile from Tanzania named Crocodylus anthropophagusa crocodile related to his most recent discovery.

Brochu says Crocodylus thorbjarnarsoni is not directly related to the present-day Nile crocodile. This suggests that the Nile crocodile is a fairly young species and not an ancient "living fossil," as many people believe. "We really don't know where the Nile crocodile came from," Brochu says, "but it only appears after some of these prehistoric giants died out."
