"Dinosaur Secret Unveiled by Ancient Crystal-Filled Rock"

A crystal stored in a mineral collection for 135 years has been found to contain the shell of a 67-million-year-old titanosaur egg. The egg was preserved by layers of solidified volcanic rock and silica-rich water that seeped inside the shell and crystalized to form a light pink and white agate mineral. The specimen was discovered by a man named Charles Fraser while living in India between 1817 and 1843 and cataloged as agate in 1883 by the Natural History Museum in the U.K. The near-perfect spherical shape of the rock and the thin layer around the crystal suggest it could be a dinosaur egg.
