Brain to body ratio
Once the biggest mammal of its time, the Coryphodon was a large creature weighing about 500 kg, about the size of a modern-day hippopotamus. Its brain size, however, only weighed around 90 grams, distinguishing it as having one of the smallest body-to-brain ratios of any mammal.
What is in a tooth?
Scientists have discovered a Coryphodon’s diet by studying its teeth. This study not only reveals what the creature ate but also its behaviour. Many animals migrate to warmer climates as the winter months approach. The Coryphodon did not migrate and instead switched between two seasons and two types of food sources.
The last of its kind
All species on Earth evolve or become extinct. Coryphodon is one mammal that became extinct and no other mammals are currently known to have evolved from it.
