Science magazine comments that "each of the five ancient animals could have answered a casting call for Star Trek". But Kaprosuchus would have resonated with the medieval and ancient imagination too, combining as it does attributes we associate with a dog, a boar, a crocodile and a dragon.
P.S. 23 Nov: the crocs have been given nicknames. The biggest is SuperCroc. PancakeCroc had an impressively flat head. BoarCroc (Kaprosuchus saharicus) had fierce-looking fangs and an armored snout for ramming. DogCroc had a fleshy nose like a dog and was limber enough to gallop. DuckCroc had broad, overhanging snout resembling a duckbill. And RatCroc had a pair of buckteeth in the lower jaw that were used to dig for food.
