By Dana Qablawi

A Little About It.

  • Was named by Edward Drinker Cope in 1879
  • Largest known Entelodont
  • Look resembles the modern day bison and white rhino
  • Also known as Dinohyus and some people refer to it as terrible pig

When Did It Exist?

  • During the late Eocene epoch to early Miocene Epoch
  • Around 20-30 million years ago
  • Believed to have lived in North America and Asia

Fossil Evidence

  • Fossils have bean located in North America
  • Fossils of other mammals have bite marks on them which match the dental patterns of the Daeodons jaw
  • 1924, archaeologists found Daeodon fossils.
  • Found a body of a man in gold clothes with the bones, remains were found in England


  • Believed to have eaten live animals, and some plants
  • Debates on whether it ate only plants or animals as well
  • Believed that it ate animals because of the size of its teeth

Possible Descendants

  • Scientists say that the Daeodon is the ancestor of the modern day pig.
  • Some palaeontologists say that they are more closely related to hippos

Link to Evolution Unit

  • The Daeodon links to the evolution unit because it is believed that the Daeodon has evolved into a pig.
  • During that time Pangea started to slowly break apart causing the species to separate.
  • As a result the Daeodon may have mated with other animals resulting into a new species with different dietary needs making it the species it is today

Why Are They Extinct?

  • Tied in with the ongoing climate change of the Oligocene and Miocene epoch
  • Global cooling - also affects their diet
- Ecosystems on land changing from tropical forests to open grasslands

- If they did eat plants then these changes would have caused a large decrease in the plants types the Daeodon ate.

  • The Daeodon made no change which showed that it either could not eat the different plant types, or it did not eat any plants in general


  • North America
  • Some people say that the Daeodon was also in Asia and was able to cross the bridge between North America and Asia at the time called Beringia
