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.
Who invented camera? Johann Zahn designed the first camera in 1685. But the first photograph was clicked by Joseph Nicephore Niepce in the year 1814. It was thousands of years back that an Iraqi scientist Ibn- al- Haytham made a mention of this kind of a device in his book, Book of Optics in 1021. The earlier cameras were incapable of saving the images and were huge in size. The first practical photography was invented by Louis Daquerre in 1829 but he took almost 10 years to produce the effective method which was named after him as daquerreotype. All this was done in Niepceâs partnership.
