The bones and eggs of a 70-million-year-old birdlike dinosaur species have been found in Patagonia by a joint Argentine/Swedish research team. What’s unique about the find is the fact that the eggs are preserved near the articulated hind limb of an adult.
Analysis of the eggshell micro-structure was used to identify this as a new species – at 2.6m, one of the largest members of the Alvarezsauridae family. The discovery of the fossils proves the Alvarezsaurids persisted in South America until Latest Cretaceous times
