Orders vs Names: An order is a large group of animals, like Proetida which includes many different kinds of trilobites but not all of them. The information we give about fossils is taken from wikipedia for the fossil name, but when that is not available, we provide information about the 'order' which contains the species. For example "Griffithidella welleri" is found in the map but not in wikipedia, so its order Proetida is used since Griffithidella welleri is a type of Proetida.
