Tyrannosaurus lived about 65 to 70 million years ago, in the late Cretaceous Period. T. rex was among the last of the big dinosaurs. Like all non-bird dinosaurs, T. rex lived in the Mesozoic era. Tyrannosaurus is believed to have lived in forests, near rivers, and in areas that were open and full of prey.

NicÃ©phore NiÃ©pce and Daguerre. The first photographic process â heliography â was invented around 1824 by NicÃ©phore NiÃ©pce.
