From today's featured article  Replica of the M. ohioensis holotype Megalograptus is a genus of eurypterid, an extinct group of aquatic arthropods, containing five species, all based on fossil material found in the United States: M. alveolatus, M. ohioensis (pictured), M. shideleri, M. welchi and M. williamsae. They were predators, with the largest and best-known species, M. ohioensis, growing to 78 centimeters (2 ft 7 in). The two most distinctive features of Megalograptus were its massive and spined forward-facing appendages, and its sharp spike-shaped telson (the last division of the body). Attached beneath the non-venomous telson were a pair of rounded blade-formed lobes which made it capable of grasping. Researchers have been able to infer the coloration that specimens might have possessed in life, believed to be brown and black, with M. ohioensis being darker than the others. Megalograptus lived in near-shore marine environments, where it used its large appendages to capture prey. The predator may have been cannibalistic at times, like many modern chelicerates.

This title was first awarded in 1928, the initial winner being Primley Sceptre, a fawn Greyhound. Previously, Crufts had used the title of Best Champion, sponsored by the Illustrated Kennel News and awarded from 1905 to 1914. The most successful breed in the modern era since the title of Best in Show was introduced has been the English Cocker Spaniel. Of the breed's seven show titles, all but one of them were owned and bred by H. S. Lloyd from the "of Ware" kennel. Only four dogs have won Best in Show on more than one occasion, and on three of these occasions they were English Cocker Spaniels owned by Lloyd. The fourth occasion was a Labrador Retriever named Bramshaw Bob, owned by the second-most successful breeder in the show's history, Countess Lorna Howe. (Full list...)
