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.
To see how the process got started we need to back up to 1822. In that year Joseph NicÃ©phore NiÃ©pce in France was first able to produce a crude photographic image. But, it was Lous Daguerre in 1839, who came up with a process that could actually be considered photography.
