Name:
Dissopsalis
Phonetic: Dis-sop-sal-is.
Named By: Pilgrim - 1910.
Classification: Chordata, Mammalia, Creodonta,
Hyaenodontidae.
Species: D. carnifex (type),
D.
pyroclasticus.
Diet: Carnivore.
Size: Unknown.
Known locations: China, India, Kenya and
Pakistan.
Time period: Serravallian to the Tortonian of the
Miocene.
Fossil representation: Several specimens but usually
of just the skull, teeth and partial mandibles. Elements of post
cranial remains have also been attributed to the genus.
Although still only known from a few scattered and incomplete fossils, Dissopsalis stands out from other creodonts by being one of the last to live. The earliest species was D. pyroclasticus from Kenya, but it is the type species of D. carnifex from Asia that confirms is position as a late surviving creodont. Dissopsalis lived at a time when other predators such as the amphicyonids (a.k.a. bear dogs) when had replaced the creodonts as the top predators of the time. However the gradual emergence of true dogs that would go on to diverge into more specialised forms such as wolves would increase competition to the point where Dissopsalis as well as the bear dogs could no longer survive.
