The dinosaur's scientific name, Beibeilong sinensis, honors Chinese culture. In Mandarin, "beibei" means "baby," and "long" translates to "dragon." The species name is derived from the Latin word for China. Thus, the dinosaur's name means "baby dragon from China."
Macroelongatoolithus eggs are often laid in clutches up to 10 feet (3 m) long.
The other bones (right) show the end of Baby Louie's right tibia and fibula. The scale bar is 5 mm (0.2 inches).
The B. sinensis embryo looks more similar to a 51-day-old crocodile embryo (right) than it does to a 78-day-old embryo (right), which is close to hatching. This comparison suggests that the B. sinensis embryo died before completing three-fourths of its development in the egg.
