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.
Indeed, the photographic self-portrait is surprisingly common in the very early days of photography exploration and invention, when it was often more convenient for the experimenting photographer to act as model as well. In fact, the picture considered by many to be the first photographic portrait ever taken was a âselfieâ. The image in question was taken in 1839 by an amateur chemist and photography enthusiast from Philadelphia named Robert Cornelius. Cornelius had set his camera up at the back of the family store in Philadelphia.
