The skull of a dinosaur embryo from Argentina is providing surprising details about baby facial features present in one species from an important dinosaur group called titanosaurs that included the largest land animals that have ever lived on Earth. “We used to get excited about the skeletons of giant dinosaurs but it always makes a difference when we get to look inside the eggs of these giants,” said paleobiologist Martin Kundrat of Pavol Jozef Safarik University’s Center for Interdisciplinary Biosciences in Slovakia, lead author of the research published in the journal Current Biology. The dinosaur appears to have had specialized facial features as a hatchling that changed as it got older.
