Understanding their tiny origins, small enough to fit inside an egg the size of an ostrich egg, would shed light on how they grew and developed. But the eggs researchers discovered at that site were flattened, making the study of a three-dimensional skull difficult. A new study focused on what researchers are calling the first discovery of a nearly intact embryonic skull of a titanosaurian sauropod. Based on their scans of the fossil, the researchers could essentially look inside the egg and determine what this hatchling looked like -- and the peculiar face looking back at them wasn't what they expected. But, Kundrát speculated, given that there is no evidence of parental care in titanosaurian dinosaurs, these babies were likely on their own for food and defense once they hatched.
