Teensy long-necked dinosaur embryo reveals weird snout horn


A rare dinosaur embryo that was nearly lost to science shows an unprecedented view of what a wee, developing sauropod dinosaur looked like before it hatched and grew into a humongous, long-necked plant-eating behemoth. As it turns out, this unknown species of titanosaur had a tiny, rhino-like horn on its snout that it lost by adulthood, a new study finds.

The nearly intact skull is all that’s left of the 80 million-year-old embryo, but reveals this wee horn in incredible detail. It’s possible the titanosaur used this horn to peck out of its egg, the researchers said, although they also had other ideas about how it broke free from its shell.
