Daguerreotype
Invented by Louis-Jacques-Mandé Daguerre and introduced worldwide in 1839, daguerreotype was almost completely superseded by 1860 with new, less expensive processes yielding more readily viewable images. In the late 20th century, there was a revival of daguerreotypy by a small number of photographers interested in making artistic use of early photographic processes.
Dakotaraptor
The first fossils of "Dakotaraptor" were found in South Dakota, United States, in 2005. In 2015, the genus "Dakotaraptor" received its name, meaning "plunderer of Dakota", when the type species "Dakotaraptor steini" was described. The fossils contain an incomplete skeleton without a skull and some individual bones. They have been found in the Maastrichtian-age Hell Creek Formation, dated to the very end of the Cretaceous period, making "Dakotaraptor" one of the last surviving dromaeosaurids.
