From The Lost World:
But the velociraptors behaved differently. There was a disorderly, chaotic feeling to the scene before him: ill-formed nests; quarreling adults; very few young and juvenille animals; the eggshells crushed; the broken mounds stepped on. Around the mounds, Levine now saw scattered small bones which he presumed where the remains of newborns. He saw no living infants anywhere in the clearing. There were three juveniles, but these younger animals were forced to fend for themselves, and they already showed many scars on their bodies. The youngsters looked thin, undernourished. Poking around the periphery of the carcass, they were cautious, backing away whenever one of the adults snapped at them.
