Earring
Ear piercing is one of the oldest known forms of body modification, with artistic and written references from cultures around the world dating back to early history. Gold, silver and bronze hoop earrings were prevalent in the Minoan Civilization (2000–1600 BCE) and examples can be seen on frescoes on the Aegean island of Santorini, Greece. During the late Minoan and early Mycenaean periods of Bronze Age Greece hoop earrings with conical pendants were fashionable. Early evidence of earrings worn by men can be seen in archeological evidence from Persepolis in ancient Persia. The carved images of soldiers of the Persian Empire, displayed on some of the surviving walls of the palace, show them wearing an earring.
James Kitching
In 1977 James Kitching recovered seven Massospondylus eggs that had been exposed by roadmaking operations in the Golden Gate Highlands National Park in South Africa. In January 2000, Professor Robert Reisz from the University of Toronto at Mississauga in Canada was on a research visit to South Africa and borrowed the fossil eggs to take back to Canada. Diane Scott of his laboratory carried out the difficult preparation under a high magnification microscope. Hans Sues, a Smithsonian palaeontologist who helped analyse the 190-million-year-old eggs — the oldest from a vertebrate animal ever discovered — confirmed that Kitching had been correct in his identification of the eggs. The embryos are so well preserved, that they have yielded remarkable insights into dinosaur biology and behaviour. They are the oldest evidence for caregiving among dinosaurs in that the animals' undeveloped teeth suggest that Massospondylus hatchlings needed help in feeding.
