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.
Other important technical advances in the history of photography, included the following. Photoetching was invented in 1822-5 by the Frenchman Joseph Niepce (1765-1833), who also made the first photograph from nature in 1826.
The first partially successful photograph of a camera image was made in approximately 1816 by NicÃ©phore NiÃ©pce, using a very small camera of his own making and a piece of paper coated with silver chloride, which darkened where it was exposed to light.
