Dinobabies: the remains of a prehistoric "daycare" are found in Neuquén. There are more than 100 bones of titanosaurs, one of the largest long-necked herbivores in Patagonia.

They believe they were specimens between 10 months and one year old. "This has never been seen, it is historical," said Leonardo Filippi, paleontologist at the Urquiza Argentine Museum in Rincón de los Sauces, Argentina.
