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.
Daguerre was the inventor of the first practical process of photography. In 1829, he formed a partnership with Niepce to improve the process Niepce had developed. In 1839, following several years of experimentation and Niepce's death, Daguerre developed a more convenient and effective method of photography and named it after himself.
