Dino Eggs…And What's Inside by Sara F. Schacter What could be

finding the baby dinosaur still inside? In a huge dinosaur
nesting ground in Argentina, scientists recently found the
fossil remains of six unhatched baby dinosaurs. About a foot
long and snuggled up inside eggs the size of grapefruit, these
dinosaur embryos have helped solve the mystery of which
dinosaurs laid the miles and miles of eggs buried in the dirt
and rock. The tiny embryos were titanosaurs—a type of sauropod,

largest land animals ever. Scientists were amazed that their
delicate skulls and fragile skin had survived long enough to
become fossilized. Some embryos still had tiny, sharp teeth in
their mouths. By studying the embryos' skulls, scientists are
learning just how dramatically the structure of the titanosaurs'
faces changed as they grew. The embryos' nostrils are at the
tips of their snouts, but by the time titano
