Catopsbaatar
Catopsbaatar is a genus of multituberculate, an extinct order of rodent-like mammals. It lived in what is now Mongolia during the late Campanian age of the Late Cretaceous Period, about 72 million years ago. The first fossils were collected in the early 1970s, and the animal was named as a new species of the genus "Djadochtatherium " in 1974, "D. catopsaloides". The specific name refers to the animal's similarity to the genus "Catopsalis". The species was moved to the genus "Catopsalis" in 1979, and received its own genus ("Catopsbaatar", Greek and Mongolian for "visible hero") in 1994. Five skulls, one molar, and one skeleton with a skull are known; the latter is the genus' most complete specimen. "Catopsbaatar" was a member of the family Djadochtatheriidae.
Blackleg (potatoes)
The symptoms of Blackleg of Potato were first described in Germany between 1878 and 1900, but the descriptions were incomplete and cannot definitively be linked to the particular disease. The first complete descriptions of Blackleg in potatoes were formed between 1901 and 1917 by several different scientists. These descriptions consisted of many different names, such as "Bacillus phytophthorus", "Bacillus omnivorus", "Bacillus oleraceae", "Bacillus atrosepticus", "Bacillus aroideae", "Bacillus solanisaprus", and "Bacillus melanogenes". Investigations between 1918 and 1958 confirmed that these bacteria were of a single species, and were officially appointed the name "Pectobacterium carotovorum". A variety of "Pectobacterium" ("P. carotovorum var. atrosepticum", which includes "B. melanogenes" and "B. phytophthorus") can be differentiated from the rest, although it is considered the same species of bacteria.
